A Multi-Center, Phase 1, Open-Label, Dose-Escalation Study of ABBV-428, an Immunotherapy in Subjects With Advanced Solid Tumors
This is an open-label, Phase I, dose-escalation study to determine the recommended Phase 2 dose (RPTD), maximum tolerated dose (MTD), and evaluate the safety and pharmacokinetic (PK) profile of ABBV-428 when administered as monotherapy or in combination with nivolumab in participants with advanced solid tumors.
18 Years to 99 Years
Accepting Healthy Volunteers?
- Participants must have an advanced solid tumor that has progressed on standard therapies known to provide clinical benefit or the participants are intolerant to such therapies.
- Participants have adequate bone marrow, renal, hepatic and coagulation function.
- For all dose expansion arms, participants must have measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1
- Participants in combination therapy cohorts must have an advanced solid tumor where the use of nivolumab is standard therapy.
- Active or prior documented autoimmune disease in the last 2 years. Participants with childhood atopy or asthma, vitiligo, alopecia, Hashimoto syndrome, Grave's disease, or psoriasis not requiring systemic treatment (within the past 2 years) are not excluded.
- Current or prior use of immunosuppressive medication within 14 days prior to the first dose (with certain exceptions).
- History of primary immunodeficiency, bone marrow transplantation, chronic lymphocytic leukemia, solid organ transplantation, or previous clinical diagnosis of tuberculosis.
- Confirmed positive test results for human immunodeficiency virus (HIV), or participants with chronic or active hepatitis B or C. Participants who have a history of hepatitis B or C who have undetectable HBV DNA or HCV RNA after anti-viral therapy may be enrolled.
- Prior grade greater than or equal to 3 immune-mediated neurotoxicity or pneumonitis (or any other unresolved or symptomatic adverse event in the last 3 months) while receiving immunotherapy.
- Male participants who are considering fathering a child or donating sperm during the study or for at least 3 or 5 months (for monotherapy and combination therapy participants, respectively) after the last dose of study drug.
