A Multicenter, Phase 1, Open-Label, Dose-Escalation Study of ABBV-181, a Monoclonal Antibody, as Monotherapy and in Combination With Another Anti-Cancer Therapy 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-181. This study will also evaluate the safety and tolerability of ABBV-181 in combination with Rovalpituzumab Tesirine and ABBV-181 in combination with venetoclax. The study will consist of 3 parts: ABBV-181 monotherapy dose escalation and expansion, ABBV-181 in combination with Rovalpituzumab Tesirine and ABBV-181 in combination with venetoclax.
18 Years to 99 Years
Accepting Healthy Volunteers?
- Participant must have an advanced solid tumor and must not be a candidate for surgical resection or other approved therapeutic regimen known to provide clinical benefit. For dose escalation, the participant may have been previously treated with a programmed cell death 1 (PD-I) targeting agent. For dose expansion, the participant must be PD-I/PD-L1 targeting agent naïve. For Part 2 ABBV-181 in combination with rovalpituzumab tesirine, the participant must have SCLC with progressive disease and have failed platinum containing therapy and be PD-1/PD-L1 targeting agent naïve. For Part 3 ABBV-181 in combination with venetoclax, the participant must have locally advanced or metastatic NSCLC and received no more than four lines of therapy in an advanced or metastatic setting and has progressed on no more than one PD-1/PD-L1 containing therapy.
- Participant has an Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 to 2 for the monotherapy cohort and an ECOG 0 to 1 for ABBV-181 in combination with rovalpituzumab tesirine cohort (Part 2) and ABBV-181 in combination with venetoclax (Part 3).
- Participants have adequate bone marrow, renal, hepatic and coagulation function.
- Participants must have measurable or evaluable disease per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 in the dose escalation portion of the trial. Participants in the expansion cohort must have measurable disease per RECIST version 1.1 or disease evaluable by assessment of tumor antigens. Participants enrolled in ABBV-181 in combination with venetoclax cohort (Part 3) must have measurable disease per RECIST version 1.1.
- Participant has received anticancer therapy including chemotherapy, immunotherapy, radiation therapy, biologic, herbal therapy, or any investigational therapy within a period of 5 half-lives, prior to the first dose of ABBV-181 or Rovalpituzumab Tesirine or venetoclax.
- For ABBV-181 plus rovalpituzumab tesirine therapy (Part 2), participant must not have had prior exposure to Rovalpituzumab Tesirine or a pyrrolobenzodiazepine (PBD) based drug.
- Participant has unresolved adverse events greater than grade 1 from prior anticancer therapy except for alopecia.
- 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 A, B or C. Subjects who have a history of hepatitis B or C who have undetectable HBV DNA or HCV RNA are anti-viral therapy may be enrolled.
- Participant has known history or inflammatory bowel disease, pneumonitis, or known uncontrolled metastases to the central nervous system (CNS) (with certain exceptions).
- Participants with a history of or ongoing pneumonitis or interstitial lung disease are also excluded.
- For ABBV-181 plus venetoclax therapy (Part 3), participant must not receive a strong or moderate inducer or inhibitor of cytochrome P450 (CYP)3A within 7 days before first venetoclax dose.
- For ABBV-181 plus venetoclax therapy (Part 3), participants with a known gastrointestinal disorder (i.e.: malabsorption syndrome), complication (i.e.: dysphagia) or surgery that could make consumption or absorption of oral medication problematic are also excluded.
