Drug: ABBV-368
Drug: ABBV-181
Registration Number
NCT03071757

Brief Summary

The primary purpose of this Phase 1, open-label study is to evaluate the safety, pharmacokinetics, and preliminary efficacy of ABBV-368 as a monotherapy and in combination with ABBV-181 in participants with locally advanced or metastatic solid tumors. The study will consist of 3 parts: ABBV-368 dose escalation, ABBV-368 tumor-specific dose expansion (triple negative breast cancer \[TNBC\] cohort and head and neck cancer cohort) and 18F-AraG Imaging Substudy.

  • 3A: Participants with locally advanced or metastatic TNBC that have exhausted standard treatment for their incurable disease and are treatment naïve to a PD-1/PD-L1 targeting agent.
  • 3B: Participants with recurrent HNSCC that are not candidates for curative treatment with local or systemic therapy, or metastatic HNSCC of the oral cavity, oropharynx, hypopharynx, and larynx that is considered incurable by local therapies. Participants must be treatment naïve to a PD-1/PD-L1 targeting agent.
  • Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0 to 2.
  • Participants must have immune-related Response Evaluation Criteria for Solid Tumors (iRECIST) evaluable or measurable disease in the PART 1 and measurable disease per iRECIST in PART 2
  • Adequate bone marrow, kidney and liver function.

Exclusion Criteria
  • Received anticancer therapy including chemotherapy, immunotherapy, radiation therapy, biologic, herbal therapy, or any investigational therapy within a period of 21 days prior to the first dose of ABBV-368.

Number of Participants With Adverse EventsMultiple time points in each cycle (each cycle is 28 days), throughout study completion, an average of 2 years, or participant becomes lost to follow up, or study termination

An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. The investigator assessed the relationship of each event to the use of study drug as either reasonable possibility or no reasonable possibility. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the subject and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment-emergent events (TEAEs/TESAEs) are defined as any event that began or worsened in severity after the first dose of study drug. For more details on adverse events please see the Adverse Event section.

Secondary Outcome Measures
NameTimeMethod
Clinical benefit rate (CBR)Multiple time points in each cycle (each cycle is 28 days), throughout study completion, an average of 2 years, or participant becomes lost to follow up, or study termination

CBR defined as the proportion of subjects with a confirmed partial response (PR), complete response (CR), or stable disease.

Progression-Free Survival (PFS)Multiple time points in each cycle (each cycle is 28 days), throughout study completion, an average of 2 years, or participant becomes lost to follow up, or study termination

PFS time is defined as the time from the first dose of study drug (Day 1) to disease progression or death, whichever occurs first.

Objective Response Rate (ORR)Multiple time points in each cycle (each cycle is 28 days), throughout study completion, an average of 2 years, or participant becomes lost to follow up, or study termination

ORR is defined as the proportion of subjects with a confirmed partial or complete response to the treatment.

Duration of Objective Response (DOR)Multiple time points in each cycle (each cycle is 28 days), throughout study completion, an average of 2 years, or participant becomes lost to follow up, or study termination

DOR defined as the time from the initial objective response to disease progression or death, whichever occurs first.
