Brief Summary:
This study is a first-in-human, open-label, multicenter, Phase 1-2 study to assess the safety, pharmacokinetics, pharmacodynamics, and preliminary clinical activity of ASTX029 administered orally to subjects with advanced solid malignancies who are not candidates for approved or available therapies.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Solid Tumor, Adult | Drug: ASTX029 | Phase 1 Phase 2 |
ASTX029 is a synthetic small molecule inhibitor of extracellular signal-regulated kinases (ERKs) 1/2. ASTX029 has not been previously evaluated in human subjects. The Phase 1 portion of this study will assess safety and determine the maximum tolerated dose, the recommended Phase 2 dose (RP2D), and the recommended dosing regimen of ASTX029 administered orally. The Phase 2 portion will assess preliminary clinical activity in tumors characterized by gene aberrations in the mitogen-activated protein kinase (MAPK) signal pathway that may confer sensitivity to ASTX029.

In Phase 1 Part B and in the Phase 2 portion of the protocol, subjects must also have documented gene alterations in the MAPK pathway as detailed in the protocol.
- In Phase 1 Part B of the protocol, subjects must have disease lesions that are amenable to biopsy.
- In the Phase 2 portion of the protocol, subjects must have measurable disease according to RECIST v1.1.
