Clinical Trial Radar

• Have histologically or cytologically confirmed SCLC with combined histologies.

• Have received any of the following therapies or drugs within the noted time intervals prior to study treatment:

  • Within 2 weeks: small molecule agents with half-life of <7 days; radiation outside the thoracic cavity including whole brain radiation. Of note, other local radiation for brain lesions (not whole brain) is allowed; local radiation for bone lesions is allowed. Palliative bone radiation or brain stereotactic radiosurgery would not require a washout period, but participants should recover from radiotherapy-related toxicity.
  • Within 4 weeks: radiation involving the thoracic cavity; small molecule targeted agents with half-life of ≥7 days; monoclonal antibodies, antibody-drug conjugates, radioimmunoconjugates, or T-cell or other cell-based therapies.
  • Have received prior treatment with anti-vascular endothelial growth factor (VEGF) monoclonal antibody, or programmed death (ligand)-1 (PD\[L\]-1)/VEGF bispecific antibody.
  • Have received systemic corticosteroids (at a dosage greater than 10 mg/day of prednisone or an equivalent dose of other corticosteroids) within 7 days prior to the initiation of study treatment. Note: local, intranasal, intraocular, intra-articular or inhaled corticosteroids, short-term use (≤7 days) of corticosteroids for prophylaxis (e.g., prevention of contrast agent allergy) or treatment of non-autoimmune conditions (e.g., delayed hypersensitivity reactions caused by exposure to allergens) are allowed.

• Have the following central nervous system metastases:

  • Participants with untreated brain metastases that are symptomatic or large (e.g., greater than 2 cm).
  • Participants with treated central nervous system (CNS) metastases who are not neurologically stable or on steroids (at a dosage greater than 10 mg/Day of prednisone or an equivalent dose of other corticosteroid) within 7 days before initiating study treatment of this study.
  • Participants with known leptomeningeal metastases.

• Have uncontrolled hypertension or poorly controlled diabetes prior to study treatment.

• Have a serious or non-healing wound, or (incompletely healed) bone fracture. This includes history of abdominal fistula, tracheoesophageal fistula, gastrointestinal perforation, or intra-abdominal abscess for which an interval of 6 months must pass before study entry. In addition, the participant must have undergone correction (or spontaneous healing) of the perforation/fistula and/or the underlying process causing the fistula/perforation.

• Have a significant risk of hemorrhage (per investigator clinical judgment) as defined in the protocol.

• Have superior vena cava syndrome or symptoms of spinal cord compression that requires urgent medical intervention.

NOTE: Other protocol defined Inclusion/Exclusion criteria apply.
