Official title

A Phase 1b Dose Escalation Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of GS-3583, a FLT3 Agonist Fc Fusion Protein, in Subjects With Advanced Solid Tumors

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study is planned to be conducted in 2 parts: Part 1: Dose Escalation and Part 2: Safety Run-In and Randomized Expansion. The primary objectives of Part 1 are 1) To characterize the safety and tolerability of GS-3583 as monotherapy in participants with advanced solid tumors. 2) To determine the maximum tolerated dose (MTD) or recommended Phase 2 dose (RP2D) of GS-3583 as monotherapy in participants with advanced solid tumors. The primary objectives of Part 2 is to assess the safety and tolerability and to determine the RP2D of GS-3583 in combination with zimberelimab (ZIM) and platinum (cisplatin or carboplatin) + 5-fluorouracil (5-FU) chemotherapy in participants with head and neck squamous cell carcinoma (HNSCC) (Cohort A) or in combination with docetaxel in participants with non-small cell lung cancer (NSCLC) (Cohort B).
