A Study of TRB191 in Patients With Extensive-stage Small Cell Lung Cancer

12. november 2026 oppdatert av: Novartis Pharmaceuticals

A Phase I, Open-label, Multi-center Study of TRB191 in Patients With Extensive Stage Small Cell Lung Cancer

The purpose of this study is to characterize the safety, tolerability, pharmacokinetics (PK), immunogenicity (IG) and preliminary anti-tumor activity and to determine a recommended dose (RD) of TRB191 in patients with extensive-stage small cell lung cancer (ES-SCLC).

Beskrivelse

Inclusion Criteria:

  • Age ≥ 18 years old
  • Histologically or cytologically confirmed and documented ES-SCLC
  • Dose escalation: Patients with ES-SCLC and disease progression after one or more chemotherapy regimens (with or without PD-L1 inhibitor) according to the local standard of care (SOC). Prior treatment with a DLL3-targeted therapy is allowed, except in cohorts designed to evaluate TRB191 in patients who are naïve to prior DLL3-targeted therapy
  • Dose expansion: Patients with ES-SCLC and disease progression after one or more chemotherapy regimens (with or without PD-L1 inhibitor), according to the local SOC. Patients must have received prior treatment with tarlatamab

Exclusion Criteria:

  • Patients with inadequate bone marrow function and/or organ functions with out-of-range laboratory values
  • Impaired cardiac function or clinically significant cardiac disease
  • Presence of symptomatic central nervous system (CNS) metastases or CNS metastases requiring local therapy or increasing doses of corticosteroids within 2 weeks prior to study entry
  • Treatment with anti-cancer therapies prior to the first dose of study treatment within the stated timeframes
  • Pregnant or nursing woman, and women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception

Other protocol-defined inclusion/exclusion criteria may apply.
