New hope for Hard-to-Treat cancers: experimental PARP inhibitor enters human trials
NCT ID NCT06380660
First seen Jun 27, 2026 · Last updated Aug 05, 2026 · Updated 2 times
Summary
This study is testing an experimental drug called ACE-86225106 in adults with advanced solid tumors that are difficult to treat or have stopped responding to standard therapies. The drug works by blocking a protein that helps cancer cells repair themselves, potentially slowing or stopping tumor growth. The main goals are to check the drug's safety, find the best dose, and see if it shrinks tumors in people with cancers like ovarian, breast, or prostate cancer linked to BRCA gene mutations.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Provide written informed consent; 2. Advanced solid tumors, difficult to treat or intolerant to standard treatment, suitable for investigational treatment; 3. Has Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1; 4. Has a life expectancy of at least 3 months; 5. Has measurable disease per RECIST 1.1, castration-resistant prostate Ccancer (CRPC) patients can be assessed according to PCWG3; 6. Adequate organ function and bone marrow function; 7. Can provide tumor specimens and blood samples for Homologous Recombination Deficiency (HRD)/ Homologous Recombination Repair (HRR) related gene testing. Exclusion Criteria: 1. Receiving any anti-cancer drugs, major surgery, extensive radiation therapy, or local radiation therapy within protocol-defined wash-out period; 2. Concomitant use of medications or herbal supplements known to be strong or moderate inhibitors or inducers of cytochrome P450 3A4 (CYP3A4); 3. Receiving continuous corticosteroid treatment with a dose of prednisone greater than 10 mg/day or an equivalent dose. 4. Receiving continuous treatment with prednisone at a dose of \>10 mg/d or other corticosteroids at an equivalent dose for any reason. 5. Any previous treatment-related toxicities have not recovered, i.e., to ≤ Grade 1 (as evaluated by NCI-CTCAE v5), except alopecia and other Grade 2 toxicities that are deemed not to affect the conduct of the study, as assessed by the sponsor and the clinical investigator. 6. Spinal cord compression or brain metastases unless asymptomatic, treated and stable. 7. Severe cardiovascular disorders. 8. Myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML) or with evidence suggesting possible MDS/AML. 9. Concomitant diseases or conditions that would preclude the absorption of the investigational product. 10. Active infections, or a known history of HIV infection, or a known active hepatitis B or C, or a known active tuberculosis. 11. Other malignancies that require treatment within 3 years prior to first dose of study investigational product. 12. Conditions with rapid deterioration during the screening period. 13. Known allergy or hypersensitivity to the investigational product or any of the excipients of the investigational product. 14. Has other medical conditions that at the discretion of investigator interfere with safety or efficacy evaluation, or affect treatment compliance.
