BAT3306 versus Keytruda as adjuvant therapy for early-stage non-small-cell lung cancer

A Phase 1, Randomized, Double-blind Study to Compare the Pharmacokinetics, Between BAT3306 and Keytruda® (Pembrolizumab) in Participants With Stage IB-IIIA Non-small Cell Lung Cancer Following Complete Resection

Phase 1 Interventional Bio-Thera Solutions · NCT07180862

This trial will test whether BAT3306 has similar pharmacokinetics and safety to Keytruda when given after surgery to adults with early-stage non-small-cell lung cancer who do not have EGFR or ALK mutations.

What this trial studies

This multicenter, randomized, double-blind, parallel-controlled Phase 1 trial will compare the pharmacokinetics (PK) of BAT3306 versus Keytruda in approximately 140 participants with completely resected early-stage NSCLC. Eligible adults without EGFR mutations or ALK rearrangements and without prior neoadjuvant/adjuvant chemo- or radiotherapy will be randomized 1:1 and receive 200 mg IV every three weeks for up to 12 months. Scheduled serum sampling will be used to analyze PK parameters, immunogenicity, and safety, with an exploratory look at disease-free survival. Randomization is managed via an IWRS and the trial is conducted at the listed Wuhan study site.

Who should consider this trial

Good fit: Adults aged 18–75 with pathologically confirmed NSCLC who had complete surgical resection, no EGFR or ALK alterations, and no prior neoadjuvant or adjuvant chemotherapy or radiotherapy are the intended participants.

Not a fit: Patients with EGFR mutations, ALK rearrangements, small cell or other excluded histologies, prior neoadjuvant therapy, extensive adjuvant chemotherapy, or planned radiotherapy are unlikely to be eligible or benefit from this trial.

Why it matters

Potential benefit: If BAT3306 proves similar to Keytruda, patients could gain access to an alternative PD‑1 antibody with comparable safety and effectiveness that may expand treatment availability.

How similar studies have performed: PD‑1 inhibitors like pembrolizumab have shown adjuvant benefit in NSCLC and other early-phase biosimilar PD‑1 candidates have demonstrated PK similarity, so this approach builds on existing, partially validated work.
