Detailed Description

This is an open-label, multicenter, Phase 1/1b study of ALTA2618, a mutant-selective and orally bioavailable AKT1 E17K inhibitor, in adults with AKT1 E17K-mutant solid tumors. This study will evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary clinical activity of ALTA2618, and aims to find the best dose. The study consists of two parts: Part 1 - Dose Escalation and Part 1b - Dose Expansion.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

  • Unresectable or metastatic disease
  • Progressed on, intolerant to, or declined prior standard-of-care therapy (including targeted therapy, if applicable) appropriate to tumor type and stage
  • Evaluable or measurable disease per RECIST v1.1
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
