Study Summary

This trial is testing a new drug, ART4215, on people with advanced cancer. The goal is to learn more about the side effects and effectiveness of the drug.

Who is the study for?
This trial is for adults with advanced or metastatic solid tumors suitable for PARP inhibitor treatment. Eligible participants may have had prior chemotherapy but not more than three regimens, and no previous PARP inhibitors unless specified. They must have at least one measurable tumor lesion, adequate organ function, and agree to use effective contraception.Check my eligibility
What is being tested?
ART4215 is being tested alone and alongside talazoparib or niraparib in patients with various cancers including breast cancer. The study aims to determine the safe dosage levels, side effects profile, and effectiveness of these treatments in combating cancer progression.See study design
What are the potential side effects?
Potential side effects include reactions related to drug infusion, fatigue, digestive issues like nausea or constipation, blood cell count changes increasing infection risk, liver or kidney function alterations. Specific side effect profiles will be studied during the trial.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Part A: Number of participants with dose limiting toxicities (DLTs) from ART4215 monotherapy, in combination with talazoparib or in combination with niraparib
Part B1 and B2: Number of participants with adverse events following administration of ART4215
Part B3: Progression free survival (PFS) as a measure of efficacy for ART4215 in combination with talazoparib or talazoparib alone
Secondary outcome measures
Assessment of lesions in (or indicative of lesions in) DNA repair pathways by immunohistochemistry for loss of shieldin complex and/or TP53BP1 or other relevant pathways
Best overall response (BOR) as a measure of efficacy for ART4215 as monotherapy, in combination with talazoparib or in combination with niraparib
Change in tumor size as a measure of efficacy for ART4215 as monotherapy, in combination with talazoparib or in combination with niraparib

Trial Design

6Treatment groups
Experimental Treatment
Group I: Part B3Experimental Treatment2 Interventions
In Part B3, approximately 120 participants with HER2 negative BRCA breast cancers will be randomized 1:1 to either ART4215 in combination with talazoparib or talazoparib alone.
Group II: Part B2Experimental Treatment1 Intervention
In Part B2 dose expansion, up to 20 participants with solid cancers with characteristics indicative of sensitivity to pol theta inhibition will receive ART4215.
Group III: Part B1Experimental Treatment1 Intervention
In Part B1 dose expansion, up to 30 participants with solid cancers that have been treated with a PARP inhibitor for an approved indication will receive ART4215.
Group IV: Part A3Experimental Treatment2 Interventions
Part A3 will evaluate ART4215 given in combination with niraparib in 21-day cycles. Up to 30 participants will participate in this dose escalation arm.
Group V: Part A2Experimental Treatment2 Interventions
Part A2 will evaluate ART4215 given in combination with talazoparib in 21 day cycles. Up to 50 participants will participate in this dose escalation arm.
Group VI: Part A1Experimental Treatment1 Intervention
Part A1 will evaluate ART4215 monotherapy administered in 21 day cycles. Up to 90 participants will participate in this dose escalation arm.
