Brief Summary:
This is a Phase 1, multicenter, open-label, dose-escalation study to evaluate the safety, tolerability, PK, PD, and clinical activity of domvanalimab (AB154) as monotherapy and in combination with zimberelimab (AB122) in participants with advanced solid malignancies.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Solid Tumor, Unspecified, Adult | Drug: Domvanalimab Drug: Zimberelimab | Phase 1 |
This is a Phase 1, multicenter, open-label, dose-escalation study to evaluate the safety, tolerability, PK, PD, and clinical activity of domvanalimab as monotherapy and in combination with zimberelimab in participants with advanced solid malignancies. In this dose escalation study, participants will receive domvanalimab administered intravenously as monotherapy or in combination with zimberelimab. Treatment will continue until progressive disease, unacceptable toxicity, withdrawal of consent, or other reasons for study drug discontinuation occurs.

Exclusion Criteria:
- Use of any live vaccines against infectious diseases (eg, influenza, varicella) within 4 weeks (28 days) of initiation of investigational product
- Underlying medical conditions that, in the Investigator's or Sponsor's opinion, will make the administration of investigational product hazardous (eg, interstitial lung disease, active infections requiring antibiotics, recent hospitalization with unresolved symptoms)
- Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial
- Is pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the study, starting with the pre-screening or screening visit through 100 days after the last dose of domvanalimab as monotherapy and in combination with zimberelimab.
- Participants who require a Legally Authorized Representative (LAR) to provide informed consent on their behalf.
- Any active autoimmune disease or a documented history of autoimmune disease or history of a syndrome that required systemic steroids or immunosuppressive medications, except for vitiligo or resolved childhood asthma/atopy. Participants with asthma who require intermittent use of bronchodilators (such as albuterol) will not be excluded from this study
- Prior malignancy active within the previous year except for locally curable cancers that have been apparently cured, such as basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the cervix, breast, or prostate cancer
- Has had prior chemotherapy, targeted small-molecule therapy, immunotherapy (tumor vaccine, cytokine, or growth factor given to control the cancer), biologic agents or radiation therapy within 4 weeks (or 5 half-lives) prior to Day 1 or has not recovered from AEs due to a previously administered agent
- Use of other investigational drugs within 28 days or at least 5 half-lives before investigational product administration.
