Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - BGB-A3055
Treatment: Drugs - Tislelizumab

Experimental: Phase 1a Part A: Dose Escalation (BGB-A3055 Monotherapy) - Different groups of participants will receive increasing doses of BGB-A3055 alone to determine the most appropriate dosage levels.

Experimental: Phase 1a Part B: Dose Escalation (BGB-A3055 + tislelizumab) - Different groups of participants will receive increasing doses of BGB-A3055 in combination with tislelizumab to determine the most appropriate dosage levels.

Experimental: Phase 1b (Dose Expansion): - Participants will receive the recommended dose for expansion phase (RDFE) of BGB-A3055 in combination with tislelizumab to provide additional information on the safety, tolerability, and potential benefits of the recommended dose.

Eligibility
Key inclusion criteria
1. Age=18 years on the day of signing the informed consent form (ICF) (or the legal age of consent in the jurisdiction in which the study is taking place, whichever is older).
2. All participants are also required to demonstrate an ECOG Performance Status score of=1 and have adequate organ function.
3. Participants with histologically confirmed advanced or metastatic solid tumors associated with high CCR8 and who have previously received available standard systemic therapy or for whom treatment is not available or not tolerated and could not receive any prior therapy targeting CCR8.
4. >=1 Measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1
5. Participants should be able to provide the archival formalin-fixed paraffin-embedded (FFPE) tumor tissues (as block or unstained slides) or fresh biopsy if there is no archival tissue at baseline. For selected cohorts, participants should be willing to provide post-treatment fresh biopsy at specified timepoints.

Key exclusion criteria
1. Active leptomeningeal disease or uncontrolled, untreated brain metastasis.
2. Active autoimmune diseases or history of autoimmune diseases that may relapse
