A Study of LY4050784 in Participants With Advanced or Metastatic Solid Tumors

Официальное название

An Open-label, Multicenter Study of LY4050784, a Selective SMARCA2/BRM Inhibitor, in Advanced Solid Tumor Malignancies With SMARCA4/BRG1 Alterations

Обзор

The main purpose of this study is to find out whether the study drug, LY4050784, is safe, tolerable and effective in participants alone or in combination with other anticancer agents. In addition, with locally advanced or metastatic solid tumors with a BRG1 (Brahma-related gene 1, also known as SMARCA4) alteration who have previously received, do not qualify for, or are refusing standard of care treatments, or there is no standard therapy available for the disease. The study is conducted in two parts - phase Ia (dose-escalation) and phase Ib (dose-optimization, dose-expansion). The study will last up to approximately 4 years.

• Phase 1a dose escalation: Presence of any alteration in SMARCA4 (BRG1)
• Phase 1b expansion: Part A: Non-small Cell Lung Cancer (NSCLC) that is locally advanced and not suitable for definitive locoregional therapy, or metastatic with presence of a known or likely loss of function alteration in SMARCA4 (BRG1) or loss of protein expression.
• Phase 1b expansion: Part B: Any tumor type (other than NSCLC) that has the presence of a known or likely loss of function alteration in SMARCA4 (BRG1) or loss of protein expression.
• Phase 1b expansion: Part C: Non-small Cell Lung Cancer (NSCLC) that is locally advanced and not suitable for definitive locoregional therapy, or metastatic with presence of a known or likely loss of function alteration in SMARCA4 (BRG1) or loss of protein expression.
• Prior Systemic Therapy Criteria:

• Phase 1a dose escalation and Phase 1b (Part B): Participants who received all standard therapies for which the individual was deemed to be an appropriate candidate by the treating Investigator; or the individual is refusing the remaining most appropriate standard of care treatment; or there is no standard therapy available for the disease.
• Phase 1b expansion (Part A): Participants must have received at least one line of therapy for advanced or metastatic disease.
• Phase 1b expansion (Part C): Participants may be treatment naïve or have received therapy for advanced or metastatic disease
