Investigational Drug
BNT327 (also known as PM8002) is an investigational bispecific antibody that targets PD‑L1 and VEGF‑A. It originated at Biotheus and is now being advanced globally by BioNTech following a licensing deal in November 2023 and a subsequent acquisition agreement announced in November 2024. Clinical development includes Phase Ib/IIa monotherapy and multiple Phase II combination studies across solid tumors. Notably, the agent is also being studied in combination with BioNTech’s TROP2 antibody–drug conjugate BNT325 (DB‑1305). Importantly, DB‑1305 is a separate drug (BNT325), not a synonym for BNT327; the pair is being combined in ongoing trials. (biotheus.com)
BNT327/PM8002 is designed to simultaneously block PD‑L1 to relieve immune checkpoint inhibition and neutralize VEGF‑A to counter tumor angiogenesis. The molecule comprises a bivalent, Fc‑silenced anti‑VEGF‑A IgG1 fused to two humanized anti‑PD‑L1 single‑domain VHHs. Preclinical data show high‑affinity binding to PD‑L1 and VEGF‑A, sub‑nanomolar functional potency in PD‑1/PD‑L1 and VEGF‑A/VEGFR2 signaling assays, and antitumor activity in vivo. The design aims to concentrate VEGF blockade within PD‑L1–positive tumor microenvironments to enhance efficacy and reduce systemic VEGF‑related toxicity. (aacrjournals.org)
Basket/solid tumors (Phase Ib/IIa, monotherapy): In an update through February 3, 2023 (n=263 enrolled; 211 evaluable), overall ORR was 15.2% with a disease control rate (DCR) of 75.4% across tumor types. Signal was observed in several cohorts: cervical cancer ORR 28% (7/25), renal cell carcinoma ORR 26.9% (7/26), platinum‑resistant ovarian cancer ORR 15.4% (4/26), and EGFR‑mutant NSCLC ORR 18.5% (5/27). (ascopubs.org)
Cervical cancer and platinum‑resistant recurrent ovarian cancer (PROC) (ASCO 2024, monotherapy subset): As of December 20, 2023, among 45 evaluable cervical cancer patients, ORR was 42.2% (including 1 CR) with DCR 93.3% and median PFS 8.3 months; PD‑L1–positive (CPS ≥1) tumors had ORR 52.4% (11/21). Among 34 evaluable PROC patients, ORR was 20.6% with DCR 67.7% and median PFS 5.3 months. (ascopubs.org)
NSCLC (ASCO 2024, monotherapy): In 61 evaluable patients with advanced NSCLC, ORR and PFS varied by cohort. Treatment‑naïve cohort (n=17) had ORR 47.1% and median PFS 10.9 months; prior EGFR‑TKI cohort (n=36) had ORR 19.4% and median PFS 4.9 months; a heavily pretreated cohort (IO and platinum‑based chemotherapy) had ORR 12.5% with median PFS 6.7 months. (ascopubs.org)
IO + ADC combination rationale: Early preclinical/clinical evidence presented in 2025 supports combining BNT327/PM8002 with BNT325/DB‑1305 (TROP2 ADC) to improve efficacy without overlapping toxicities; this combination entered clinical evaluation in 2024 (part of an ongoing Phase 1/2 study).

Basket/solid tumors (Phase Ib/IIa, monotherapy; data to February 3, 2023): Any‑grade treatment‑related adverse events (TRAEs) occurred in 68.8% with grade ≥3 TRAEs in 18.3%. Common TRAEs included proteinuria (17.5%), hypertriglyceridemia (11.4%), elevated AST (9.9%) and ALT (9.5%), hypoalbuminemia (8.7%), and elevated GGT (6.8%). Discontinuations due to TRAEs occurred in 13.7%; no treatment‑related deaths were reported. (ascopubs.org)
NSCLC (ASCO 2024, monotherapy): Any‑grade TRAEs occurred in 85.2% with grade ≥3 in 18%. Immune‑related AEs in 37.7%; treatment‑related SAEs in 9.8%; discontinuations due to TRAEs in 8.2%. Common TRAEs (≥15%) included hypertension, hypothyroidism, proteinuria, hypoalbuminemia, hypocalcemia, and elevated AST/LDH. (ascopubs.org)
Cervical cancer and PROC (ASCO 2024, monotherapy subset): Any‑grade TRAEs in 95.4% and grade ≥3 in 35.6%; any‑grade immune‑related AEs in 57.5% (grade ≥3 in 8%). Discontinuations due to TRAEs in 14.9%. Proteinuria, hypertension, anemia, elevated WBC count, and thrombocytosis were among the most common events. (ascopubs.org)

HealthScout AI summary: Adults with advanced/metastatic NSCLC (squamous or non-squamous), including both first-line AGA-negative and previously treated patients (with genotype-specific prior therapy, e.g., post–third-gen EGFR TKI), receive the HER3-directed topoisomerase I ADC BNT326 combined with the PD-L1/VEGF-A bispecific antibody BNT327, with arms also testing each agent alone and standard-of-care comparators by PD-L1 status. Excludes prior HER3/topo I ADC exposure (with limited exceptions), uncontrolled ILD/pneumonitis, active CNS disease needing steroids/anticonvulsants, significant effusions, and high-grade prior irAEs leading to ICI discontinuation.
