Durvalumab, a recombinant fully human anti-programmed-death ligand-1 (anti-PD-L1) monoclonal antibody, is an antineoplastic agent.1 The drug is an IgG1 kappa immunoglobulin.1
Durvalumab is used in combination with platinum-containing chemotherapy as neoadjuvant treatment, followed by durvalumab continued as a single agent as adjuvant treatment after surgery, for the treatment of resectable (tumors ≥4 cm and/or node positive) non-small cell lung cancer (NSCLC) with no known epidermal growth factor receptor (EGFR) mutations or anaplastic lymphoma kinase (ALK) rearrangements in adults.1
Durvalumab is also used for the treatment of unresectable stage III NSCLC that has not progressed following platinum-based chemotherapy combined with radiation therapy in adults.1, 11, 12
Durvalumab is also used in combination with tremelimumab-actl and platinum-based chemotherapy for the treatment of metastatic NSCLC with no sensitizing EGFR mutations or ALK genomic tumor aberrations in adults.1
Neoadjuvant and Adjuvant Treatment of Resectable Non-small Cell Lung Cancer
The current indication for the use of durvalumab in combination with platinum-containing chemotherapy as neoadjuvant treatment, followed by continued use of durvalumab as a single-agent as adjuvant treatment after surgery, for the treatment of adults with resectable NSCLC is based principally on the results of a double-blind, randomized, placebo-controlled, phase 3 study (AEGEAN).1, 14 Patients with newly diagnosed, previously untreated, resectable NSCLC, regardless of tumor programmed death-ligand 1 (PD-L1) expression, were enrolled.1, 14 There were 802 patients randomized (stratified by stage and level of PD-L1 expression) in a 1:1 ratio to receive a neoadjuvant-adjuvant durvalumab regimen or placebo regimen.1, 14 Those randomized to the durvalumab regimen received neoadjuvant durvalumab (1500 mg by IV infusion) once every 3 weeks for up to 4 cycles in combination with platinum-based chemotherapy.1, 14 Platinum-based regimens for NSCLC of squamous tumor histology consisted of either carboplatin (AUC 6) and paclitaxel (200 mg/m2) on day 1 of each 3-week cycle, or cisplatin (75 mg/m2) on day 1 and gemcitabine (1250 mg/m2) on day 1 and day 8 of each 3-week cycle, for 4 cycles.1 Platinum-based regimens for NSCLC of non-squamous tumor histology consisted of pemetrexed (500 mg/m2) and cisplatin (75 mg/m2) on day 1 of each 3-week cycle, or pemetrexed (500 mg/m2) and carboplatin (AUC 5) on day 1 of each 3-week cycle, for 4 cycles.1 Patients continued to receive IV durvalumab or placebo every 4 weeks for up to 12 cycles after surgery.14
The patients enrolled in AEGEAN were 65 years of age (median); 72% of patients were male, 54% were white, 41% were Asian, 0.9% were Black, 1.4% were American Indian or Alaska Native; 16% were Hispanic or Latino; 49% had squamous histology; 28% had Stage II disease and 71% had Stage III; 86% were current or past smokers; and 33% had PD-L1 expression <1%.1, 14 All patients enrolled had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.1, 14 There were 77.6% of patients in the durvalumab group who completed surgery compared with 76.7% of patients in the placebo group.14 The main efficacy endpoints were pathological complete response and event-free survival.1, 14
At a pre-planned interim analysis of the AEGEAN study (46.3 months after study initiation), there were substantial improvements in pathological complete response and event-free survival in patients who received the durvalumab-containing regimen compared with those receiving placebo.1, 14 The median event-free survival had not been reached for the durvalumab with chemotherapy regimen and was 25.9 months for the placebo with chemotherapy regimen.1, 14 The pathological complete response rate was 17.2% for the durvalumab with chemotherapy regimen compared with 4.3% for the placebo with chemotherapy regimen.1, 14
Unresectable Non-small Cell Lung Cancer
The current indication for durvalumab in the treatment of unresectable NSCLC that has not progressed following platinum-based chemotherapy combined with radiation therapy is based principally on the results of a multicenter, double-blind, randomized, placebo-controlled, phase 3 trial (PACIFIC).1, 11, 12 In this study, 713 patients with unresectable stage III NSCLC that had not progressed following at least 2 cycles of platinum-based chemotherapy and concurrent radiation therapy within 42 days of study initiation, were randomized (stratified by gender, age, and smoking history) in a 2:1 ratio to receive either durvalumab (10 mg/kg by IV infusion every 2 weeks) or placebo.1, 11, 12 Treatment was continued for up to 12 months or until disease progression or unacceptable toxicity occurred.1, 11, 12 The median age of patients in this study was 64 years; 69% of patients were white; 27% were Asian; 70% were male; 75% were former smokers and 16% were current smokers; and 51% had a baseline ECOG performance status of 1.1 All patients had received radiation therapy and 99% of patients had received concomitant platinum-based chemotherapy; 55 or 42% of patients had received prior treatment with cisplatin- or carboplatin-based regimens, respectively, and 2% switched between cisplatin and carboplatin.1 This study excluded patients whose disease progressed during platinum-containing chemotherapy and radiation therapy, those with autoimmune disease within the previous 2 years, and those receiving immunosuppressive agents.1 The primary measures of efficacy were progression-free survival and overall survival (as evaluated by a blinded independent central review committee according to RECIST); an additional outcome measure was overall response rate.1, 11
In the PACIFIC study, patients receiving durvalumab had a longer median progression-free survival compared with patients receiving placebo (16.8 months versus 5.6 months).1, 11 Median overall survival had not been reached at the time of the interim analysis (at a median follow-up of 14.5 months).11 At the time of the interim analysis, patients receiving durvalumab had higher overall response rates compared with those receiving placebo (26 versus 14%); complete responses were achieved in 1 or 0% of patients receiving durvalumab or placebo, respectively.1
At a pre-planned interim overall survival analysis of the PACIFIC study at a median follow-up of 25.2 months, patients receiving durvalumab had a longer median overall survival compared with patients receiving placebo (median not reached versus 28.7 months, respectively).1, 12 A 5-year survival outcomes study of PACIFIC reported outcomes at a median duration of follow-up of 34.2 months for all randomly assigned patients in PACIFIC and 61.6 months for censored patients (defined as patients last known to be alive).15 The median overall survival for patients in the durvalumab group was 47.5 months versus 29.1 months for patients in the placebo group.15 The 5-year overall survival rate was estimated to be 42.9 and 33.4% for the durvalumab and placebo groups, respectively.15
Metastatic Non-small Cell Lung Cancer
The current indication for durvalumab, in combination with tremelimumab and platinum-based chemotherapy, for the treatment of metastatic NSCLC without EGFR or ALK genomic aberrations in adults is based principally on the results of a randomized, open-label, active-controlled, phase 3 study (POSEIDON).1, 16 In this study, 1013 adults with previously untreated metastatic NSCLC were randomized (stratified by PD-L1 expression, disease stage, and histology) 1:1:1 to receive tremelimumab plus durvalumab and chemotherapy, durvalumab plus chemotherapy, or chemotherapy alone.1, 16 Those randomized to the tremelimumab plus durvalumab group received tremelimumab 75 mg (or 1 mg/kg for patients <30 kg) with durvalumab 1500 mg and platinum-based chemotherapy every 3 weeks for 4 cycles, followed by durvalumab 1500 mg every 4 weeks until disease progression.1, 16 There was a fifth dose of tremelimumab given at week 16 in combination with durvalumab dose 6.1, 16 Patients in the durvalumab plus chemotherapy group received durvalumab 1500 mg plus chemotherapy for up to 4 cycles of 21 days each, followed by durvalumab 1500 mg once every 4 weeks until disease progression.16 Patients in the chemotherapy group received therapy for up to 6 cycles that were 21 days each.16 Chemotherapy regimen options included one of the following: nab-paclitaxel (100 mg/m2) on days 1, 8, and 15 with carboplatin (AUC 5-6) on day 1 every 3 weeks for any histology; pemetrexed (500 mg/m2) with carboplatin (AUC 5-6) or cisplatin (75 mg/m2) every 3 weeks for non-squamous NSCLC; or gemcitabine (1000 or 1250 mg/m2) on days 1 and 8 with cisplatin (75 mg/m2) or carboplatin (AUC 5-6) on day 1 every 3 weeks for squamous NSCLC.1, 16
The patients in the POSEIDON trial were 63 years of age (median); 77% of patients were male, 57% were white, 34% were Asian, 3% were American Indian or Alaska Native, 2% were Black, 0.3% were Native Hawaiian or Other Pacific Islander; 79% were former or current smokers; 63% had non-squamous histology; and 71% had a PD-L1 expression tumor proportion score of less than 50%.1 All patients had an ECOG performance status of 0 or 1.1 The main efficacy measures were progression-free survival and overall survival.1, 16 The median follow-up for censored patients was 10.3 months and 34.9 months for progression-free survival and overall survival, respectively.16
In the POSEIDON trial, durvalumab, in combination with tremelimumab and platinum-based chemotherapy, substantially improved overall survival and progression-free survival.1, 16 The median progression-free survival was 6.2 months for patients in the durvalumab plus tremelimumab and chemotherapy group and 4.8 months for the chemotherapy alone group.16 The median overall survival was 14 months and 11.7 months for the durvalumab plus tremelimumab and chemotherapy group and chemotherapy alone group, respectively.1, 16 Results of a subgroup analysis (based on age and tumor PD-L1 expression) were generally consistent.16 The progression-free survival and overall survival benefits appeared more prominent in non-squamous (versus squamous) NSCLC histology.16
Guidelines for NSCLC have been published by the American Society of Clinical Oncology (ASCO), including for stage III and stage IV NSCLC.17, 18 For patients with stage III NSCLC receiving concurrent chemoradiation without disease progression during initial therapy, the ASCO guideline states that consolidation with durvalumab for up to 12 months should be offered.17 The living guideline by ASCO for the treatment of patients with stage IV NSCLC without driver mutations states that clinicians may offer durvalumab and tremelimumab plus platinum-based chemotherapy as a first-line treatment option for stage IV patients with good performance status.18
Durvalumab is used as a single agent for the treatment of limited-stage small cell lung cancer (SCLC) that has not progressed following concurrent platinum-based chemotherapy and radiation therapy in adults.1 Durvalumab has been designated an orphan drug by FDA for the treatment of this type of SCLC.4
Durvalumab is also used in combination with etoposide and either carboplatin or cisplatin as first-line treatment for extensive-stage SCLC in adults.1 Durvalumab has been designated an orphan drug by FDA for the treatment of this type of SCLC.4
Limited-stage Small Cell Lung Cancer
The current indication for durvalumab as a single agent for the treatment of limited-stage SCLC that has not progressed following concurrent platinum-based chemotherapy and radiation is based principally on the results of a randomized, double-blind, placebo-controlled study (ADRIATIC).1, 19 In this study, 730 adults with histologically or cytologically confirmed limited-stage SCLC whose disease had not progressed following concurrent chemoradiation therapy were randomized (stratified by stage [I/II versus III]) and receipt of prophylactic cranial irradiation) 1:1:1 to receive durvalumab, durvalumab plus tremelimumab, or placebo.1, 19 Those randomized to the tremelimumab group received tremelimumab (75 mg) with durvalumab (1500 mg) every 4 weeks for 4 cycles followed by durvalumab (1500 mg) every 4 weeks until disease progression, unacceptable toxicity, or up to a maximum of 24 months.1, 19 Those in the durvalumab group received durvalumab (1500 mg) in combination with tremelimumab-matched placebo every 4 weeks for 4 cycles, followed by durvalumab (1500 mg) every 4 weeks.1, 19 Those in the placebo group received durvalumab and tremelimumab-matched placebos every 4 weeks for 4 cycles, followed by the durvalumab-matched placebo every 4 weeks thereafter.1, 19
The patients in the ADRIATIC trial were 62 years of age (median).19 There were 69% of patients who were male; 50% were white, 0.8% were Black, 48% were Asian, 4.2% were Hispanic or Latino, 22% were current smokers, and 68% were past smokers.1 There were 87.4% of patients with stage III disease at diagnosis; previous concurrent chemotherapy included regimens with cisplatin plus etoposide (66.2%) and carboplatin plus etoposide (33.8%).1, 19 All patients had an ECOG performance status of 0 or 1.1 The main efficacy measures were overall survival and progression-free survival.1, 19 For censored patients, the median follow-up for overall survival was 37.2 months for both the durvalumab and placebo group; the median follow-up for progression-free survival was 27.4 months and 27.7 months for the durvalumab group and placebo group, respectively.19
In the ADRIATIC trial, durvalumab substantially improved overall survival and progression-free survival.1, 19 The median progression-free survival was 16.6 months for patients in the durvalumab group and 9.2 months for the placebo group.19 The median overall survival was 55.9 months and 33.4 months for the durvalumab and placebo groups, respectively.1, 19
Extensive-stage Small Cell Lung Cancer
The current indication for durvalumab in combination with etoposide and either carboplatin or cisplatin as first-line treatment for extensive-stage SCLC in adults is based principally on the results of a randomized, open-label, active-controlled, phase 3 study (CASPIAN).1, 20 In this study, 805 adults with treatment-naïve histologically or cytologically documented extensive-stage SCLC were randomized (stratified according to planned platinum therapy) in a 1:1:1 ratio to receive durvalumab plus platinum-etoposide, durvalumab plus tremelimumab plus platinum-etoposide, or platinum-etoposide alone.20 Those randomized to the tremelimumab plus durvalumab group receive IV tremelimumab (75 mg) with durvalumab (1500 mg) and platinum-based chemotherapy every 3 weeks for 4 cycles, followed by durvalumab (1500 mg) every 4 weeks until disease progression or unacceptable toxicity.20 Patients in the durvalumab group received durvalumab (1500 mg) with platinum-based chemotherapy every 3 weeks for 4 cycles, followed by durvalumab (1500 mg) every 4 weeks.20 Patients in the chemotherapy alone group received therapy for up to 6 cycles total and prophylactic cranial irradiation after chemotherapy based on the investigator's discretion.20 The chemotherapy regimen for all groups consisted of the investigator's choice of either carboplatin (AUC 5 or 6) or cisplatin (7580 mg/m2) on Day 1 and etoposide (801000 mg/m2) IV on days 1, 2, and 3 of each 21-day cycle.1 Continuation of durvalumab as a single agent was permitted beyond disease progression if the patient was deriving clinical benefit and was clinically stable.1, 20
The patients in the CASPIAN trial were 63 years of age (median); 70% were male, 84% were white, 15% were Asian, 0.9% were Black; and 93% were former or current smokers.1, 20 There were 90% of patients that had stage IV disease, and 10% had brain metastasis at baseline.1, 20 All patients had an ECOG performance status of 0 or 1.1, 20 Within the study, 25% of patients received cisplatin, and 74% received carboplatin.1 The main efficacy measure was overall survival of durvalumab plus chemotherapy versus chemotherapy alone.1, 20 Additional efficacy measures were progression-free survival and objective response rate.1 The median follow-up for censored patients for overall survival was 14.2 months.20
In the CASPIAN trial, durvalumab, in combination with platinum-based chemotherapy versus chemotherapy alone, substantially improved overall survival.1, 20 The median overall survival was 13 and 10.3 months for the durvalumab plus chemotherapy group and chemotherapy alone group, respectively.1, 20 The median progression-free survival was 5.1 months for patients in the durvalumab plus chemotherapy group and 5.4 months for the chemotherapy alone group.1, 20 The investigators-assessed confirmed objective response rate was higher with durvalumab plus chemotherapy (68%) compared with chemotherapy alone (58%).1, 20 Results of a subgroup analysis (based on baseline clinical and demographic characteristics) found a consistent overall survival benefit with durvalumab plus chemotherapy.20 An updated analysis of the CASPIAN trial at a median follow-up of 25.1 months was conducted and found sustained benefit in overall survival with durvalumab plus chemotherapy (median, 12.9 months) compared with chemotherapy alone (median, 10.5 months).21
Guidelines for SCLC have been published by ASCO and Ontario Health (Cancer Care Ontario).22, 23 For patients with extensive-stage SCLC, the ASCO/Ontario Health guideline states first-line systemic therapy with cisplatin or carboplatin plus etoposide plus immunotherapy (e.g., atezolizumab or durvalumab) followed by maintenance immunotherapy should be offered if there are no contraindications to immunotherapy.22 An ASCO guideline rapid recommendation update states that patients with limited-stage SCLC who have completed concurrent chemoradiotherapy and do not have disease progression should be offered consolidation immunotherapy (i.e., durvalumab) for up to 2 years if there are not any contraindications to immunotherapy.23 In addition, this ASCO guideline update states that for patients with limited stage SCLC and ECOG performance status of 3 or 4 due to SCLC who have been treated with concurrent or sequential chemotherapy and radiotherapy may be offered consolidation immunotherapy (i.e., durvalumab) for up to 2 years if there are no contraindications and there is improvement in performance status.23
Durvalumab is used in combination with gemcitabine and cisplatin for the treatment of locally advanced or metastatic biliary tract cancer in adults.1 Durvalumab has been designated an orphan drug by FDA for the treatment of this type of cancer.4
The current indication for durvalumab in combination with gemcitabine and cisplatin for the treatment of locally advanced or metastatic biliary tract cancer is based principally on the results of a randomized, double-blind, placebo-controlled, phase 3 study (TOPAZ-1).1, 24 In this study, 685 patients with histologically confirmed locally advanced unresectable or metastatic biliary tract cancer who had not previously received systemic therapy were randomized (stratified by disease status [recurrent versus initially unresectable] and primary tumor location [intrahepatic cholangiocarcinoma, extrahepatic cholangiocarcinoma, or gallbladder cancer]) in a 1:1 ratio to receive durvalumab plus chemotherapy or placebo plus chemotherapy.1, 24 Patients in the durvalumab plus chemotherapy group received IV durvalumab (1500 mg) on day 1 plus gemcitabine (1000 mg/m2) and cisplatin (25 mg/m2) on days 1 and 8 of each 21-day cycle for up to 8 cycles, followed by durvalumab (1500 mg) every 4 weeks until disease progression or unacceptable toxicity.1, 24 Patients in the placebo plus chemotherapy group received placebo on day 1 of each cycle with the same chemotherapy regimen as the durvalumab group for up to 8 cycles, followed by placebo every 4 weeks.1, 24 Treatment after disease progression was allowed if the patient was clinically stable and deriving clinical benefit.1
The patients enrolled in the TOPAZ-1 study were 64 years of age (median); 50% of patients were male, 37% were white, 56% were Asian, 2% were Black, 0.1% were American Indian or Alaskan Native; 20% of patients had recurrent disease; and 86% had metastatic and 14% had locally advanced disease.1 The main efficacy endpoint was overall survival.1, 24 Additional efficacy endpoints included progression-free survival and overall response rate.1, 24 The median duration of follow-up was 16.8 months for patients in the durvalumab group and 15.9 months for patients in the placebo group.24
In the TOPAZ-1 study, median overall survival and progression-free survival was substantially prolonged for patients in the durvalumab plus chemotherapy group compared with patients in the chemotherapy alone group.1, 24 The median overall survival for the durvalumab plus chemotherapy group was 12.8 months versus 11.5 months in the placebo plus chemotherapy group.1, 24 The median progression-free survival was 7.2 months and 5.7 months for the durvalumab plus chemotherapy and placebo plus chemotherapy groups, respectively.1, 24 Objective response rates were 26.7% for patients treated with durvalumab plus chemotherapy and 18.7% for patients treated with placebo plus chemotherapy.1, 24 Results for overall and progression-free survival were generally consistent across the subgroups analyzed.24 An updated analysis of the TOPAZ-1 study was conducted at a median follow-up of 23.4 months in the durvalumab plus chemotherapy group and 22.4 months in the placebo plus chemotherapy group.25 The median overall survival at this cutoff was 12.9 months and 11.3 months for the durvalumab and placebo groups, respectively.25
Recommendations for the treatment of advanced and metastatic disease are available from international experts.26, 27 For advanced or metastatic biliary tract cancer, cisplatin-gemcitabine combined with either durvalumab or pembrolizumab is a viable first-line treatment option.27
Durvalumab is used in combination with tremelimumab-actl for the treatment of unresectable hepatocellular carcinoma in adults.1 Durvalumab has been designated an orphan drug by FDA for the treatment of this type of cancer.4
The current indication for durvalumab in combination with tremelimumab for the treatment of unresectable hepatocellular carcinoma is based principally on the results of a randomized, open-label, phase 3 study (HIMALAYA).1, 28 The HIMALAYA study enrolled 1171 adults with Barcelona Clinic Liver Cancer (BCLC) stage B or C hepatocellular carcinoma and Child-Pugh class A liver function who were previously untreated with prior systemic therapy.1, 28 Patients enrolled were randomized (stratified according to presence of macrovascular invasion, etiology of liver disease, and ECOG performance status) 1:1:1 to receive durvalumab, durvalumab plus tremelimumab, or sorafenib.1, 28 Patients in the durvalumab plus tremelimumab group received durvalumab (1500 mg) with tremelimumab (as a one-time single IV infusion of 300 mg on the same day), followed by durvalumab every 4 weeks.1, 28 Patients in the durvalumab group received durvalumab (1500 mg) every 4 weeks; patients in the sorafenib group received oral sorafenib (400 mg) twice daily.1, 28 Treatment was continued until disease progression or unacceptable toxicity.1, 28 Treatment was also permitted beyond disease progression if the patient was deriving clinical benefit and was clinically stable.1, 28
The patients in the HIMALAYA study were 65 years of age (median); 85% of patients were male; 46% were white; 49% were Asian; 2% were Black, 5% were Hispanic or Latino; 26% had macrovascular invasion, and 53% had extrahepatic spread.1 In terms of viral etiology, 31% had hepatitis B, 27% had hepatitis C, and 42% were uninfected.1 The main measure of efficacy was overall survival; progression-free survival and overall response rate were additional efficacy measures.1, 28 The median follow-up for this study was 33.2 months for durvalumab plus tremelimumab, 32.6 months for durvalumab, and 32.2 months for sorafenib.28
In HIMALAYA, durvalumab plus tremelimumab substantially improved overall survival compared to placebo in patients with unresectable hepatocellular carcinoma.1, 28 Median overall survival was 16.4 for the durvalumab plus tremelimumab group and 13.8 months for the placebo group.1, 28 Median progression-free survival was 3.8 months for the durvalumab plus tremelimumab group and 4.1 months for the placebo group.1, 28 Confirmed objective response rates were 20.1 and 5.1% with durvalumab plus tremelimumab and sorafenib groups, respectively.1, 28 A 4-year overall survival analysis of the HIMALAYA study was also conducted.29 For this analysis, the median follow-up was 49.1 months for the durvalumab plus tremelimumab group and 47.3 months for the sorafenib group.29 The median overall survival at this time point was 16.4 months and 13.8 months for the durvalumab plus tremelimumab and sorafenib groups, respectively.29
Guidelines for systemic therapy for advanced hepatocellular carcinoma have been published by ASCO.30 For first-line treatment of advanced hepatocellular carcinoma in patients with Child-Pugh class A liver disease and ECOG performance status of 0 or 1, atezolizumab plus bevacizumab or durvalumab plus tremelimumab may be offered.30 Sorafenib, lenvatinib, or durvalumab may also be offered as first-line treatment for these patients when there are contraindications to atezolizumab plus bevacizumab or durvalumab plus tremelimumab.30 If sorafenib or lenvatinib were used first-line, another tyrosine kinase inhibitor (TKI), ramucirumab, nivolumab plus ipilimumab, or durvalumab may be recommended for appropriate patients.30
A guideline on the treatment of hepatocellular carcinoma from the American Association for the Study of Liver Diseases (AASLD) provides similar recommendations, stating that atezolizumab plus bevacizumab or durvalumab plus tremelimumab are first-line therapies for advanced hepatocellular carcinoma in patients with Child-Pugh class A liver disease.33 In patients with contraindications to these therapies, the AASLD recommends sorafenib or lenvatinib for first-line systemic treatment.33
Durvalumab is used in combination with carboplatin and paclitaxel, followed by durvalumab as a single agent, for the treatment of primary advanced or recurrent endometrial cancer that is mismatch repair deficient, as determined by an FDA-approved test, in adults.1
The current indication for durvalumab in combination with carboplatin and paclitaxel, followed by durvalumab as a single agent, for the treatment of primary advanced or recurrent endometrial cancer is based primarily on the results of a randomized, double-blind, placebo-controlled, phase 3 study (DUO-E).1, 31 There were 718 patients with newly diagnosed advanced or recurrent endometrial cancer that were randomized (stratified by tumor mismatch repair status [proficient or deficient], disease status [recurrent or newly diagnosed], and geographic region) 1:1:1 to receive durvalumab in combination with carboplatin and paclitaxel, placebo in combination with carboplatin and paclitaxel, or durvalumab plus olaparib in combination with carboplatin and paclitaxel.1, 31 The chemotherapy regimen consisted of the following for all patients: carboplatin (AUC 5 or 6) and paclitaxel (175 mg/m2) once every 3 weeks for 6 cycles.1, 31 Patients in the durvalumab plus chemotherapy group also received durvalumab 1120 mg once every 3 weeks for a maximum of 6 cycles, followed by 1500 mg of durvalumab once every 4 weeks as maintenance until disease progression or unacceptable toxicity.1, 31 Patients in the durvalumab plus olaparib and chemotherapy also received the same regimen of durvalumab plus olaparib 300 mg tablets twice daily during the maintenance treatment period.31 Patients in the placebo plus chemotherapy group received matching placebo for durvalumab and olaparib.31
The patients enrolled in DUO-E were 63 years of age (median); 62% of patients were white, 31% were Asian, 2% were Black, 7% were Hispanic or Latino, 1% were America Indian or Alaska Native; 48% were newly diagnosed and 52% had recurrent disease.1 The histologic subtypes were mostly endometrioid (78%), followed by mixed epithelial (6%), carcinosarcoma (5%), and serous (4%).1 There were 80% of patients in the chemotherapy only group and 81% of patients in the durvalumab plus chemotherapy group that had mismatch repair proficient tumors.31 The main efficacy outcome of this trial was progression-free survival.1 For censored patients, the median duration of follow-up was 12.6 months for the chemotherapy only group and 15.4 months for the durvalumab plus chemotherapy group.31 For all tumor types (i.e., mismatch repair proficient and deficient), there was a substantially longer median progression-free survival in the durvalumab plus chemotherapy group (10.2 months) than in the chemotherapy only group (9.6 months).31 In an exploratory analysis based on mismatch repair status, the improvement in progression-free survival was primarily attributed to patients with mismatch repair deficient tumors.1 Within this subgroup of patients, the median progression-free survival had not been reached for the durvalumab plus chemotherapy group compared with a median overall survival of 7 months for the chemotherapy only group.1, 31
The American College of Obstetricians and Gynecologists (ACOG) has published a practice bulletin on the management of endometrial cancer.32 This was published before durvalumab, in combination with carboplatin and paclitaxel, was approved for use in endometrial cancer and therefore does not discuss the use of durvalumab in treatment.32
Administer durvalumab by IV infusion after dilution.1
Administer the diluted durvalumab solution through a sterile, low-protein-binding 0.2- or 0.22-µm inline filter.1
Store durvalumab refrigerated at 2-8°C in the original carton to protect from light.1 Do not freeze or shake.1
Administer diluted solutions of durvalumab immediately after preparation.1 If the diluted solution is not administered immediately, store it for up to 8 hours at room temperature (up to 25°C) or up to 28 days at 2-8°C (total storage time from initial vial entry for preparation of the dilution until start of the IV infusion).1 Do not freeze diluted solutions of the drug.1
Discard any unused portion in the vial or infusion bag since durvalumab injection contains no preservative.1
Do not administer durvalumab simultaneously through the same IV line with any other drug.1
For IV infusion, dilute the appropriate dose of durvalumab injection concentrate (containing 50 mg/mL) with an appropriate volume of 0.9% sodium chloride or 5% dextrose injection to a final concentration between 1-15 mg/mL.1 Prior to administration, visually inspect the solution and container for particulate matter and discoloration.1 The solution should be clear to opalescent and colorless to slightly yellow; do not use the solution if it is cloudy or discolored or if foreign particles are present.1 Mix the diluted solution by gentle inversion and do not shake.1
Administer durvalumab by IV infusion over 60 minutes.1
When used with tremelimumab-actl, infuse tremelimumab-actl first, followed by durvalumab on the same day of dosing.1
When used with tremelimumab-actl and platinum-based chemotherapy, infuse tremelimumab-actl first, followed by durvalumab, and then platinum-based chemotherapy on the same day of dosing.1
When used with tremelimumab-actl and pemetrexed therapy, infuse tremelimumab-actl first, followed by durvalumab, and then pemetrexed therapy on the same day of dosing.1
When used with carboplatin and paclitaxel, infuse durvalumab first and then carboplatin and paclitaxel on the same day of dosing.1
When used with tremelimumab-actl, administer tremelimumab-actl over 60 minutes followed by a 60-minute observation period.1 Then administer durvalumab as a separate IV infusion over 60 minutes.1

Immune-mediated Adverse Reactions
Durvalumab is a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death receptor1 (PD-1) or the PD-ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions.1 Important immune-mediated adverse reactions listed may not include all possible severe and fatal immune-mediated reactions.1
The incidence and severity of immune-mediated adverse reactions were similar when durvalumab was administered as a single agent or in combination with chemotherapy or in combination with tremelimumab-actl and platinum-based chemotherapy.1
Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue.1 Immune-mediated adverse reactions can occur at any time after starting treatment with a PD 1/PD L1 blocking antibody.1 While immune-mediated adverse reactions usually manifest during treatment with PD-1/PD-L1 blocking antibodies, immune-mediated adverse reactions can also manifest after discontinuation of PD-1/PD-L1 blocking antibodies.1
Early identification and management of immune-mediated adverse reactions are essential to ensure safe use of PD-1/PD-L1 blocking antibodies.1 Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions.1 Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment.1 In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection.1 Institute medical management promptly, including specialty consultation as appropriate.1
Withhold or permanently discontinue durvalumab depending on severity.1 In general, if durvalumab requires interruption or discontinuation, administer systemic corticosteroid therapy (1 mg to 2 mg/kg per day prednisone or equivalent) until improvement to grade 1 or less.1 Upon improvement to grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month.1 Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy.1 Certain reactions, such as endocrinopathies and dermatologic reactions, do not necessarily require systemic steroids.1
Durvalumab can cause immune-related pneumonitis.1 The incidence of pneumonitis is higher in patients who have received prior thoracic radiation.1
Durvalumab as a Single Agent : In patients who received durvalumab as a single agent in clinical trials in which radiation therapy was generally not administered immediately prior to initiation of durvalumab, the incidence of immune-mediated pneumonitis was 2.4% (34/1414), including fatal (<0.1%), and grade 3-4 (0.4%) adverse reactions.1 Events resolved in 19 of the 34 patients and resulted in permanent discontinuation in 5 patients.1 Systemic corticosteroids were required in 19 of 34 patients with pneumonitis who did not receive chemoradiation prior to initiation of durvalumab.1

Immune-mediated rash or dermatitis occurred in 7.2% (43/596) of patients receiving durvalumab in combination with tremelimumab-actl and platinum-based chemotherapy, including grade 3 (0.3%) adverse reactions.1 Events resolved in 32 of the 43 patients and resulted in permanent discontinuation in 2 patients.1 Systemic corticosteroids were required in all patients with immune-mediated rash or dermatitis.1
Immune-mediated pancreatitis occurred in 2.3% (9/388) of patients receiving durvalumab in combination with tremelimumab-actl, including grade 4 (0.3%) and grade 3 (1.5%) adverse reactions.1 Events resolved in 6 of the 9 patients.1 Systemic corticosteroids were required in all 9 patients, and of these, 7 patients required high-dose corticosteroid treatment (at least 40 mg prednisone or equivalent per day).1
Other Immune-mediated Adverse Reactions
Other clinically important, immune-mediated adverse reactions that occurred at an incidence of less than 1% each in patients who received durvalumab or durvalumab in combination with tremelimumab-actl, or were reported with the use of other PD-1/PD-L1 blocking antibodies, involved the following general systems: cardiac/vascular, nervous system, ocular, gastrointestinal, musculoskeletal, connective tissue, endocrine, hematologic, and immune systems.1
Durvalumab can cause severe or life-threatening infusion-related reactions.1 Monitor for signs and symptoms of infusion-related reactions.1 Interrupt, slow the rate of, or permanently discontinue durvalumab based on the severity.1 For grade 1 or 2 infusion-related reactions, consider using pre-medications with subsequent doses.1
Infusion-related reactions occurred in 2.2% (42/1889) of patients receiving durvalumab as a single agent, including grade 3 (0.3%) adverse reactions.1
Infusion-related reactions occurred in 2.6% (10/388) patients receiving durvalumab in combination with tremelimumab-actl.1
Infusion-related reactions occurred in 2.9% (17/596) of patients receiving durvalumab in combination with tremelimumab-actl and platinum-based chemotherapy, including grade 3 (0.3%) adverse reactions.1
Complications of Allogeneic Hematopoietic Stem Cell Transplantation (HSCT) After Durvalumab
Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a PD-1/L-1 blocking antibody.1 Transplant-related complications include hyperacute graft-versus-host-disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease (VOD) after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause).1 These complications may occur despite intervening therapy between PD-1/L-1 blockade and allogeneic HSCT.1
Follow patients closely for evidence of transplant-related complications and intervene promptly.1 Consider the benefits versus risks of treatment with a PD-1/L-1 blocking antibody prior to or after an allogeneic HSCT. 1
Fetal/Neonatal Morbidity and Mortality
Based on the mechanism of action of durvalumab and data from animal studies, the drug can cause fetal harm when administered to pregnant women.1 In animal reproduction studies, administration of durvalumab to cynomolgus monkeys from the onset of organogenesis through delivery resulted in increased premature delivery, fetal loss, and premature neonatal death.1
Verify pregnancy status in women of reproductive potential prior to initiation of durvalumab.1 Advise pregnant women of the potential risk to a fetus.1 Advise females of reproductive potential to use effective contraception during treatment with durvalumab and for 3 months after the last dose.1
In patients who received durvalumab across the PACIFIC, CASPIAN, TOPAZ-1, HIMALAYA, POSEIDON, DUO-E, AEGEAN, and other clinical trials, 3.2% of evaluable patients tested positive for anti-durvalumab antibodies, and 19.2% of patients positive for anti-drug antibodies (ADAs) had neutralizing antibodies against durvalumab.1 No clinically important effects of ADAs on durvalumab pharmacokinetics or safety were identified; however, the effect of these ADAs on the effectiveness of durvalumab is unknown.1
Based on findings from animal studies and the mechanism of action of durvalumab, the drug can cause fetal harm when administered to pregnant women.1 There are no available data on use of durvalumab in pregnant women.1
In animal reproduction studies, administration of durvalumab to pregnant cynomolgus monkeys from the confirmation of pregnancy through delivery at exposure levels approximately 620 times higher than those observed at the clinical dose of 10 mg/kg based on AUC, resulted in an increase in premature delivery, fetal loss, and premature neonatal death.1
Human immunoglobulin G1 (IgG1) is known to cross the placental barrier; therefore, durvalumab has the potential to be transmitted from the mother to the developing fetus.1 Apprise pregnant women of the potential risk to a fetus.1
There are no data on the presence of durvalumab in human milk, its effects on the breast-fed child, or the effects on milk production.1 Maternal IgG is known to be present in human milk.1 The effects of local GI exposure and limited systemic exposure in the breast-fed child to durvalumab are unknown.1
Durvalumab was present in the milk of lactating cynomolgus monkeys and was associated with premature neonatal death.1
Because of the potential for adverse reactions in a breast-fed child, advise women not to breast-feed during treatment with durvalumab and for 3 months after the last dose.1
Females and Males of Reproductive Potential
Verify pregnancy status in women of reproductive potential prior to initiation of durvalumab.1
Durvalumab can cause fetal harm when administered to a pregnant woman.1 Advise women of reproductive potential to use effective contraception during treatment with durvalumab and for 3 months following the last dose.1
Safety and efficacy of durvalumab have not been established in pediatric patients.1

Of the 393 patients with unresectable hepatocellular carcinoma (uHCC) treated with durvalumab in combination with tremelimumab-actl, 50% of patients were ≥65 years of age and 13% of patients were ≥75 years of age.1 No overall differences in safety or effectiveness of durvalumab have been observed between patients ≥65 years of age and younger adults.1
Of the 235 patients with endometrial cancer treated with durvalumab with carboplatin and paclitaxel, 49% of patients were ≥65 years of age and 12% of patients were ≥75 years of age.1 No overall differences in safety or effectiveness of durvalumab have been observed between patients ≥65 years of age and younger adults.1
There were no clinically important differences in the pharmacokinetics of durvalumab in mild or moderate hepatic impairment (bilirubin ≤3x upper limit of normal [ULN] and any AST).1 The effect of severe hepatic impairment (bilirubin >3x ULN and any AST) on durvalumab pharmacokinetics is unknown.1
There were no clinically important differences in the pharmacokinetics of durvalumab in mild or moderate renal impairment (creatinine clearance 3089 mL/min).1 The effect of severe renal impairment (creatinine clearance 1529 mL/min) on durvalumab pharmacokinetics is unknown.1

No formal drug interaction studies have been performed to date.1
No cytochrome P-450 (CYP) based drug interactions are anticipated since durvalumab is a monoclonal antibody.2
Durvalumab, a recombinant fully human anti-programmed-death ligand-1 (anti-PD-L1) monoclonal antibody, is an antineoplastic agent.1 The drug is an IgG1 kappa immunoglobulin that binds to PD-L1.1
The immune-checkpoint receptor programmed-death receptor-1 (PD-1) is expressed on activated T cells, B cells, macrophages, and dendritic cells.7, 8, 9 Overexpression of PD-1 ligands on the surface of tumor cells results in activation of PD-1 and CD80 (i.e., B7.1) and suppression of cytotoxic T-cell activity, T-cell proliferation, and cytokine production.1, 8 Durvalumab blocks the interaction between PD-L1 and the receptors PD-1 and CD80, resulting in activation of the antitumor immune response without inducing antibody-dependent cell-mediated cytotoxicity (ADCC).1, 8, 10 The drug also has been shown to reduce tumor growth in mouse tumor models.1, 9
Pharmacokinetic exposure of durvalumab increased more than dose proportionally at doses <3 mg/kg (0.3 times the approved recommended dosage) and dose proportionally at doses ≥3 mg/kg every 2 weeks.1 Steady state was achieved at approximately 16 weeks.1 The pharmacokinetics of durvalumab is similar when assessed as a single agent, when in combination with chemotherapy, when in combination with tremelimumab-actl, and when in combination with tremelimumab-actl and platinum-based chemotherapy.1 Durvalumab clearance decreases over time.1 The elimination half-life is approximately 21 days.1
There were no clinically important differences in the pharmacokinetics of durvalumab based on body weight, age, sex, race, albumin levels, lactate dehydrogenase levels, soluble PD-L1, tumor type, mild or moderate renal impairment, and mild or moderate hepatic impairment.1 The effect of severe renal or hepatic impairment on the pharmacokinetics of durvalumab is unknown.1
