About this study

Official title: A Phase 1b Followed by Phase II Expansion Trial of Combination of Pembrolizumab and ADG106 in Advanced Solid Cancers and Triple Negative Breast Cancer (ComPACT)

This is a phase Ib followed by phase II clinical trial evaluating the safety and efficacy of combination of ADG106 with pembrolizumab in patients with metastatic cancers. The Phase Ib dose finding part will include all solid tumor subtypes with treatment refractory disease, while phase II will focus on only patients with TNBC.

Read the detailed description

2.1 Hypothesis

  • Combination of ADG106 and pembrolizumab is safe with a reasonable toxicity profile.
  • Combination of ADG106 and pembrolizumab is effective and can improve outcomes in patients with advanced TNBC.
  • Predictive biomarkers may help select patients most likely to benefit from combination therapy.

2.2 Primary Objectives Phase Ib

  • Evaluate the safety and tolerability of combination of ADG106 with pembrolizumab in patients with advanced solid tumors.
  • Determine recommended phase II dose (RP2D) of ADG106 in combination with pembrolizumab.

Phase II • Evaluate the clinical efficacy of ADG106 plus pembrolizumab in terms of ORR in patient with advanced TNBC with CPS ≥1

2.3 Secondary Objectives Phase Ib

  • Evaluate preliminary anti-tumor effect of combination of ADG106 with pembrolizumab in terms of ORR, disease control rate (DCR), PFS and OS in patients with treatment refractory solid tumors

Phase II

  • Evaluate clinical efficacy of ADG106 plus pembrolizumab in terms of DCR, PFS and OS in patients with advanced TNBC with CPS≥1
  • Evaluate clinical efficacy of ADG106 plus pembrolizumab in terms of ORR, DCR, PFS and OS in patients with advanced TNBC with CPS≥10

2.4 Exploratory Objectives

  • Evaluate predictive biomarkers (e.g., tumor PD-L1 CPS score) for response to ADG106 plus pembrolizumab.
  • Evaluate changes in tumor microenvironment with combination of ADG106 plus pembrolizumab.
  • Evaluate changes in tumor genomic expression profile with combination of ADG106 plus pembrolizumab.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Pembrolizumab & ADG106 (Phase Ib) and Pembrolizumab & ADG106 (Phase II) in people with Advanced Solid Tumor and Triple Negative Breast Cancer, run by National University Hospital, Singapore at 1 site in Singapore.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 28 inclusion and 23 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 25 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Soo Chin Lee (+65 6908 2222, soo_chin_lee@nuhs.edu.sg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participant with treatment related toxicities (Phase Ib) (time frame: 3 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05491083, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Jul 2025.
