An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related, that occurred after a participant provided informed consent. Abnormal laboratory values or test results occurring after informed consent constituted AEs only if they induced clinical signs or symptoms, were considered clinically meaningful, required therapy (e.g., hematologic abnormality that required transfusion), or required changes in the study drug(s). A TEAE was defined as any AE either reported for the first time or the worsening of a pre-existing event after the first dose of study drug.
A DLT was defined as the occurrence of any protocol-defined toxicity occurring up to and including Day 28, except those with a clear alternative explanation (e.g., disease progression) or transient (≤72 hours) abnormal laboratory values without associated clinically significant signs or symptoms based on investigator determination. All DLTs were assessed by the investigator using Common Terminology Criteria for Adverse Events (CTCAE) v4.03 criteria.
The RP2D of the combination of INCB001158 and chemotherapy in 21-day (for gemcitabine/cisplatin) or 28-day (for mFOLFOX6 or paclitaxel) treatment cycles in participants with advanced or metastatic solid tumors was determined. After the dose escalation was completed, the INCB001158 dose level that was pharmacologically active and tolerable in combination with each chemotherapy regimen (i.e., maximum tolerated dose or lower) was determined to be the RP2D. The RP2D was then further assessed in tumor expansion cohorts in Phase 2.
ORR was defined as the percentage of participants with a best overall response of complete response (CR) or partial response (PR), as determined by investigator assessment of radiographic disease as per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 (v1.1). CR: disappearance of all target and non-target lesions and no appearance of any new lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in the short axis to \<10 millimeters (mm). PR: complete disappearance or at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference the baseline sum diameters, no new lesions, and no progression of non-target lesions. Analysis was conducted by cohort (tumor type) in Phase 2 because different tumor types could have different response criteria or different background response rates.
An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related, that occurred after a participant provided informed consent. Abnormal laboratory values or test results occurring after informed consent constituted AEs only if they induced clinical signs or symptoms, were considered clinically meaningful, required therapy (e.g., hematologic abnormality that required transfusion), or required changes in the study treatment(s). A TEAE was defined as any adverse event that started or worsened after the first dose of study drug.

INCB001158 is an investigational small molecule being studied for the treatment of Biliary Tract Cancer (BTC) and Metastatic Cancer. It has been evaluated in clinical trials for advanced or metastatic solid tumors, including colorectal, gastric, head and neck, lung, renal cell, bladder, urothelial, and mesothelioma cancers.
INCB001158 is an arginase inhibitor. It works by blocking the enzyme arginase, which is involved in the breakdown of arginine, an amino acid essential for T-cell function. By inhibiting arginase, INCB001158 aims to enhance the immune system's ability to fight cancer cells.
INCB001158 is being developed by Incyte Corporation, a biopharmaceutical company traded on the NASDAQ under the ticker symbol INCY. Incyte is conducting clinical trials to evaluate the safety and efficacy of this investigational drug in patients with various solid tumors.
INCB001158 is in Phase 1 clinical development. It has completed two Phase 1 trials, one as a single agent and in combination with immune checkpoint therapy, and another in combination with chemotherapy. The drug is investigational and has not been approved by regulatory authorities.
INCB001158 has been studied in two completed clinical trials. NCT02903914 evaluated it as a single agent and in combination with immune checkpoint therapy in patients with advanced or metastatic solid tumors. NCT03314935 studied it in combination with chemotherapy in subjects with solid tumors, including biliary tract cancer.
INCB001158 is also known by the name 1,158 in some contexts, but no other alternative names have been reported. It is a distinct investigational compound developed by Incyte Corporation and is not the same as any approved drug.
