Clinical trials overview
The trial data show four interventional studies of Incb099280 in people with cancer.[1][2][3][4] Two were Phase 2 studies and two were Phase 1 studies.[1][2][3][4] All four trials are marked as completed.[1][2][3][4]
Who was studied
One Phase 2 study looked at people with recurrent or advanced/metastatic solid tumors who were immunotherapy-naïve, meaning they had not received immunotherapy before.[1] Another Phase 2 study focused on people with advanced cutaneous squamous cell carcinoma, including previously untreated or recurrent locally advanced or metastatic disease that was not suitable for curative surgery or radiotherapy.[3]
The Phase 1 combination study with adagrasib enrolled adults with advanced solid tumors harboring a KRASG12C mutation.[2] The Phase 1 study with ipilimumab included participants with selected solid tumors.[4] In simple terms, these studies focused on adults with cancers that were already advanced and needed new treatment options.[1][2][3][4]
What the trials measured
The Phase 2 studies measured objective response, which means whether the cancer shrank in a confirmed way.[1][3] They used standard response rules such as RECIST v1.1, and one study also used composite criteria for metastatic cSCC and WHO criteria for locally advanced cSCC.[1][3]
All studies tracked treatment-emergent adverse events (TEAEs), which are side effects or medical problems that happen after treatment starts.[1][2][3][4] They also looked at how often these events caused dose interruption, dose reduction, or stopping the study drug.[1][2][3][4] The safety checks included physical exams, vital signs, electrocardiograms, and laboratory tests.[1][3]
The Phase 1 combination studies also measured dose-limiting toxicities (DLTs), which are side effects severe enough to limit dosing.[2][4] One of these studies aimed to find the maximum tolerated dose (MTD) or one or more recommended dose(s) for expansion (RDEs), while the other aimed to identify one or more RDEs.[2][4] In patient terms, these outcomes help researchers decide what dose can be given safely and what dose should be studied next.[2][4]
Study phases and treatment plans
The two Phase 2 studies tested Incb099280 as a single oral treatment at 400 mg BID, 600 mg BID, and 800 mg BID, according to the study summaries.[1][3] These studies were designed to learn about safety, tolerability, and early signs of benefit in larger patient groups.[1][3]
The Phase 1 studies tested Incb099280 in combination with other cancer medicines.[2][4] One study combined it with adagrasib, and the other combined it with ipilimumab.[2][4] These early studies focused on safety and dose finding before any larger testing could happen.[2][4]
Completed studies at a glance
The largest study in the data set enrolled 328 participants and studied recurrent or advanced/metastatic solid tumors in immunotherapy-naïve people.[1] The advanced cSCC Phase 2 study enrolled 241 participants.[3] The Phase 1 adagrasib combination study enrolled 125 participants, and the Phase 1 ipilimumab combination study enrolled 124 participants.[2][4]
Together, these studies show that research on Incb099280 has centered on advanced cancer settings, especially solid tumors and cutaneous squamous cell carcinoma.[1][2][3][4] The main questions were whether treatment was safe, how well it was tolerated, what dose could be used, and whether the cancer showed a response.[1][2][3][4]
