Subcutaneous versus intravenous pembrolizumab, in combination with chemotherapy, for treatment of metastatic non-small-cell lung cancer: the phase III 3475A-D77 trial.
Background: Pembrolizumab with berahyaluronidase alfa is for subcutaneous (s.c.) administration. The phase III open-label 3475A-D77 study (NCT05722015) assessed s.c. pembrolizumab versus intravenous (i.v.) pembrolizumab, plus chemotherapy, for treatment of metastatic non-small-cell lung cancer (mNSCLC).
Patients and methods: Participants with newly diagnosed stage IV squamous or nonsquamous NSCLC without sensitizing EGFR, ALK, or ROS1 alterations were randomized 2 : 1 to pembrolizumab s.c. 790 mg every 6 weeks (q6w) or pembrolizumab i.v. 400 mg q6w (18 cycles), each given with platinum-doublet chemotherapy. Dual primary endpoints were pharmacokinetic exposure measures of cycle 1 area under the curve (AUC0-6 weeks) and steady-state trough concentration (Ctrough) of pembrolizumab. The noninferiority margin for AUC0-6 weeks and Ctrough geometric mean ratios (GMRs) of pembrolizumab s.c. versus i.v. was specified as 0.8. Secondary endpoints included additional pharmacokinetic exposure measures, pembrolizumab immunogenicity, efficacy, and safety.
Results: In total 377 participants were randomized to the pembrolizumab s.c. (n = 251) or i.v. (n = 126) arms. The median time from randomization to data cut-off (12 July 2024) was 9.6 months (range 6.2-16.4 months). The median injection time for pembrolizumab s.c. was 2.0 min (range 1-12 min). The GMR [96% confidence interval (CI)] for cycle 1 AUC0-6 weeks was 1.14 (1.06-1.22); P < 0.0001. The GMR (94% CI) for steady-state Ctrough was 1.67 (1.52-1.84); P < 0.0001. Secondary pharmacokinetic endpoints were within established bounds for pembrolizumab. Anti-pembrolizumab antibodies were detected in 1.4% (pembrolizumab s.c. arm) and 0.9% (pembrolizumab i.v. arm) of participants. For the pembrolizumab s.c. versus i.v. arms, objective response rates (ORRs) were 45.4% versus 42.1% (ORR ratio 1.08, 95% CI 0.85-1.37). Other efficacy measures were similar and safety profiles were consistent between treatment arms.
Conclusions: Overall exposure and trough concentrations of pembrolizumab s.c. 790 mg q6w were noninferior to those of pembrolizumab i.v. 400 mg q6w given with chemotherapy in participants with treatment-naive mNSCLC. Results support pembrolizumab s.c. as a treatment option in all indications where pembrolizumab i.v. can be used.
期刊介绍：
Annals of Oncology, the official journal of the European Society for Medical Oncology and the Japanese Society of Medical Oncology, offers rapid and efficient peer-reviewed publications on innovative cancer treatments and translational research in oncology and precision medicine.
The journal primarily focuses on areas such as systemic anticancer therapy, with a specific emphasis on molecular targeted agents and new immune therapies. We also welcome randomized trials, including negative results, as well as top-level guidelines. Additionally, we encourage submissions in emerging fields that are crucial to personalized medicine, such as molecular pathology, bioinformatics, modern statistics, and biotechnologies. Manuscripts related to radiotherapy, surgery, and pediatrics will be considered if they demonstrate a clear interaction with any of the aforementioned fields or if they present groundbreaking findings.
Our international editorial board comprises renowned experts who are leaders in their respective fields. Through Annals of Oncology, we strive to provide the most effective communication on the dynamic and ever-evolving global oncology landscape.
