New drug combo tested for tough cancers, but study halted early
NCT ID NCT03522142
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage trial tested an experimental drug called INCB081776, alone or with an immunotherapy (retifanlimab), in 83 adults with advanced solid tumors like lung, kidney, or melanoma cancer. The goal was to check safety and find the right dose. However, the study was terminated early, so the full picture is unclear.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- INCB081776 (an experimental drug) and retifanlimab (an immunotherapy)
- What this could lead to
- If successful, this could point toward a new treatment option for people with advanced solid tumors who have run out of standard therapies.
- What could go wrong
- This was an early Phase 1 trial, so safety and dosing were still being figured out. The study was terminated early, so results are limited and may not lead to a usable treatment.

Inclusion Criteria: • Male and female participants at least 18 years of age with advanced malignancies who have received or been intolerant to standard therapy: Parts 1A and 2A: * Histologically confirmed advanced or metastatic gastric or GEJ adenocarcinoma, HCC, melanoma, NSCLC, RCC, soft-tissue sarcoma, SCCHN (recurrent or metastatic), TNBC, or urothelial carcinoma. Additional tumor histologies, including MSI-H tumors, may be allowed with approval from the medical monitor. * Measurable disease per RECIST v1.1. Parts 1B and 2B: • Histologic confirmation of the cohort-specific tumor types specified below: Cohort 1 - Advanced or metastatic melanoma Cohort 2 - Advanced or metastatic NSCLC Cohort 3 - Recurrent or metastatic SCCHN Cohort 4 - Advanced or metastatic soft-tissue sarcoma * Cohorts 1-3 must have received 1 prior PD-1/L1 treatment and have experienced PD during or after that treatment and have progressed on other SOC therapy(ies); Cohort 4 must be PD-1/L1 treatment naïve but have progressed on SOC therapy(ies). * Measurable disease per RECIST v1.1. * Must be willing to submit to a fresh baseline tumor biopsy and an on-treatment biopsy between Cycle 2 Day 1 and Cycle 3 Day 1. * Care should be taken to biopsy the same lesion for the baseline and on-treatment samples. If a participant has a solitary target lesion, this should not be biopsied. Part 1C: * Participants with relapsed/refractory AML following standard therapy; acute promyelocytic leukemia (M3) and therapy-related AML are excluded. * FLT3-ITD and IDH1/2 wild-type or mutated are eligible; appropriate targeted therapy for participants with actionable mutations must have been received. Exclusion Criteria: * Laboratory values not within the protocol-defined range. * History of retinal disease as defined in the protocol. * Clinically significant cardiac disease as per protocol-defined criteria. * History or presence of an ECG that, in the investigator's opinion, is clinically meaningful as per protocol-defined criteria. * Untreated brain or central nervous system (CNS) metastases or brain or CNS metastases that have progressed as per protocol-defined criteria. * Active or inactive autoimmune disease or syndrome that has required systemic treatment in the past 2 years or receiving systemic therapy for an autoimmune or inflammatory disease. * Prior Grade 3 or higher immune-related AEs or any ocular toxicity on prior immunotherapy as per protocol-defined criteria. * Receipt of any vitamin K antagonists, systemic corticosteroids, live vaccines, or treatment with any anticancer medications or investigational drugs within the protocol-defined intervals. * Has not recovered to ≤ Grade 1 or baseline from toxic effects of prior therapy and/or complications from prior surgical intervention before starting study treatment. * Active infection requiring systemic therapy. * Evidence of hepatitis B virus or hepatitis C virus infection or risk of reactivation. * Known history of HIV (HIV 1/2 antibodies).
