Background:
NSCLC patients with STK11 gene mutations could not benefit from immunotherapy, according to the data of multiple clinical trials. This is associated with immunosuppressive tumor microenvironment (TME) due to elevated AXL expression, and deficiency in pro-inflammatory cytokines and effector T cells. AXL inhibitor bemcentinib (formerly BGB324) has been found to improve the effectiveness of immunotherapy of immune checkpoint inhibitors. FC084CSA is a high selective AXL inhibitor.
Methods:
This is an ongoing first-in-human, phase I study of FC084CSA in patients with advanced solid tumors. The primary objective is to evaluate the safety and tolerability of FC084CSA. The secondary objectives include preliminary efficacy and pharmacokinetics.
Results:
As of January 10th, 2024, 9 patients with a median age of 60 years (44-73) were enrolled in 4 different dose levels: 100mg QD, 200mg QD, 400mg QD and 600mg QD. All patients had ≥ 2 prior lines of prior therapy. No dosing-limiting toxicities were observed. 8 (88.9%) patients experienced treatment-related adverse events (TRAEs). Most TRAEs were grade 1 or 2 and only one grade 3 TRAE was observed. The most common TRAEs (≥20%) included increased blood lactate dehydrogenase (44.4%), elevated gamma-glutamyl transferase (33.3%), proteinuria (33.3%), anemia (33.3%), increased aspartate aminotransferase (22.2%), weight loss (22.2%), increased blood creatinine (22.2%) and vomiting (22.2%). A total of 8 patients had at least 1 post-baseline tumor assessment. Objective response rate (ORR) was 0% and disease control rate (DCR) was 62.5% (5/8).
Conclusions:
FC084CSA was well tolerated in patients with previously heavily treated solid tumors. Clinical trial information: NCT06231550.
