Overview
Brief Summary
The primary objective of the study is to evaluate the safety, tolerability, dose-limiting toxicity (DLT) and pharmacokinetics (PK) of acasunlimab (also known as GEN1046) administered as monotherapy or in combination with pembrolizumab in Japanese study participants with malignant solid tumors.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Participant must have a histologically-confirmed non-central nervous system (CNS) solid tumor that is metastatic or unresectable and for whom there is no available standard therapy likely to confer clinical benefit; or a participant who is not a candidate for such available therapy and for whom, in the opinion of the investigator, experimental therapy with acasunlimab or acasunlimab in combination with pembrolizumab may be beneficial.
- •Asian race and Japanese ethnicity.
- •Have measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.
- •Have Eastern Cooperative Oncology Group (ECOG) 0-
- •Have an acceptable hematological status.
- •Have acceptable liver function.
- •Have an acceptable coagulation status.
- •Have acceptable renal function.
- •Should provide a tumor tissue sample (formalin-fixed paraffin-embedded \[FFPE\] blocks/slides) from archival tissue or fresh biopsy collected before C1D1, preferably derived from advanced disease stage.
Exclusion Criteria
- •Have uncontrolled intercurrent illness, including but not limited to:
- •Ongoing or active infection requiring intravenous treatment with anti-infective therapy, or any ongoing systemic inflammatory condition requiring further diagnostic work-up or management during screening.
- •Symptomatic congestive heart failure (Grade III or IV as classified by the New York Heart Association), unstable angina pectoris or cardiac arrhythmia.
- •Uncontrolled hypertension defined as systolic blood pressure ≥ 160 mmHg and/or diastolic blood pressure ≥ 100 mmHg, despite optimal medical management.
- •Ongoing or recent evidence of autoimmune disease.
- •History of irAEs that led to prior checkpoint treatment discontinuation.
- •Prior history of myositis, Guillain-Barré syndrome, or myasthenia gravis of any grade.
- •History of chronic liver disease or evidence of hepatic cirrhosis.
- •Evidence of interstitial lung disease.
- •History of non-infectious pneumonitis that has required steroids or currently has pneumonitis.

Outcomes
Primary Outcomes
Elimination half-life (t 1/2) of Acasunlimab
Time Frame: Predose and postdose at multiple timepoints of each cycle (Cycle length=21 days)
Number of Participants with Adverse Events (AEs)
Time Frame: From first dose date up to end of the safety follow up period, 90 days after last dose
An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
Maximum (Peak) Plasma Concentration (Cmax) of Acasunlimab
Time Frame: Predose and postdose at multiple timepoints of each cycle (Cycle length=21 days)
Number of Participants with Dose limiting Toxicities (DLTs)
Time Frame: During first cycle (Cycle length=21 days) in each cohort
Determine the DLT profile of acasunlimab administered as monotherapy or in combination with pembrolizumab. The DLTs will be graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) criteria version 5.0.
Plasma Trough (Pre-dose) Concentrations (Cthrough) of Acasunlimab
Time Frame: Predose and postdose at multiple timepoints of each cycle (Cycle length=21 days)
Area under the concentration time curve (AUC) of Acasunlimab
Time Frame: Predose and postdose at multiple timepoints of each cycle (Cycle length=21 days)
Time to Reach Cmax (Tmax) of Acasunlimab
Time Frame: Predose and postdose at multiple timepoints of each cycle (Cycle length=21 days)
Secondary Outcomes
- Number of Participants with Anti-Drug Antibody (ADA) to Acasunlimab(Up to 2 years)
