Study of GS-2426 in Participants With Advanced Solid Tumors

15. maj 2026 opdateret af: Gilead Sciences

A Phase 1, Multicenter, Open-Label Clinical Study to Evaluate the Safety and Tolerability of GS-2426 in Participants With Advanced MTAP-Deleted Solid Tumors

The goal of this clinical study is to learn more about the study drug GS-2426, and how safe and tolerable it is in participants with advanced methylthioadenosine phosphorylase (MTAP)-deleted solid tumors.

The primary objective of this study is to evaluate the safety and tolerability of GS-2426 in participants with MTAP-deleted advanced solid tumors and to determine the maximum tolerated dose (MTD)/maximum administered dose (MAD) and the recommended phase II dose (RP2D).

Beskrivelse

Key Inclusion Criteria:

  • Participants 18 years of age or older (≥ 19 years old for participants in South Korea).
  • Histologically or cytologically confirmed advanced malignant solid tumors, who have progressed on, are intolerant to or are ineligible for standard therapy, or have no standard treatment options.
  • Participant tumors are MTAP-deficient.
  • Adequate organ function
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
  • All participants must provide a pretreatment tumor tissue sample.

Key Exclusion Criteria:

  • Participants with plans to breastfeed during the study period or within 7 days following the last dose of study intervention.
  • Have not recovered (ie, returned to Grade 1 or baseline) from clinically significant AEs due to a previously administered agent or a previous intervention as assessed by the investigator.
  • Active second malignancy. Individuals with a history of malignancy who have been completely treated with no evidence of active cancer for 5 years prior to enrollment, or individuals with surgically cured tumors with low risk of recurrence may be enrolled.
  • Requirement for ongoing therapy with any prohibited medications .
  • Prior therapy with a PRMT5 inhibitor or methionine adenosine transferase 2a (MAT2A ) inhibitor.
  • Have serious infection requiring antibiotics within 14 days prior to the first dose.
  • Uncontrolled concurrent diseases

Note: Other protocol defined Inclusion/Exclusion criteria may apply.

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Phase 1a: Monotherapy Dose Escalation
Participants will receive escalating doses of GS-2426 monotherapy, until disease progression, or until the participant meets other study drug discontinuation criteria as specified in protocol, or up to a maximum of 105 week, whichever occurs first.
Medicin: GS-2426
Administered Orally
Eksperimentel: Phase 1b: Monotherapy Dose Expansion
Participants will be enrolled in different indication-specific cohorts. Participants will receive GS-2426 monotherapy at the recommended dose until disease progression, or until the participant meets other study drug discontinuation criteria as specified in protocol, or up to a maximum of 105 weeks, whichever occurs first.
