Deciphera Announces First Patient Treated in Phase 1 Study of DCC-3116 in Patients with Advanced or Metastatic Tumors with a Mutant RAS or RAF Gene
– Phase 1 Study will Assess First-in-Class Switch-control ULK Kinase Inhibitor Designed to Inhibit Autophagy as a Single Agent and in Combination with a MEK Inhibitor –
“Approximately one third of all cancers, including a high percentage of pancreatic, lung, colorectal, and melanoma cancers, are driven by mutations in RAS or RAF genes, representing what we believe to be one of the largest unmet medical needs in oncology,” said
Autophagy, a catabolic process in which cells recycle components to generate energy, is often upregulated in cancer cells when cells are stressed or damaged due to anti-cancer treatments. The ULK kinase initiates the autophagy pathway and provides a potential targeted approach to selectively inhibiting autophagy in cancers caused by RAS or RAF mutations. In preclinical studies, DCC-3116 was observed to potently and durably inhibit autophagy in RAS and RAF mutant cancer cell lines through the inhibition of ULK kinase. In addition, in preclinical studies, DCC-3116 also blocked the increase in autophagy induced by inhibitors of the MAPK pathway as a resistance mechanism. The Company’s in vitro and in vivo studies have demonstrated that DCC-3116 in combination with inhibitors of the MAPK pathway may block the growth of cancers caused by RAS or RAF mutations.
The clinical development plan for DCC-3116 will focus on documented RAS and RAF cancer mutations, which utilize autophagy for tumor growth and survival. The Phase 1, multicenter, open-label, first-in-human study will evaluate DCC-3116 as a single agent and in combination with trametinib, an FDA-approved MEK inhibitor, in patients with advanced or metastatic tumors with a mutant RAS or RAF gene. Assuming positive results in the dose escalation phase, combination expansion cohorts are currently planned in patients with advanced or metastatic pancreatic ductal adenocarcinoma (PDAC) with KRAS or BRAF mutations, non-small cell lung cancer (NSCLC) with KRAS, NRAS, or BRAF mutations, colorectal cancer (CRC) with KRAS, NRAS, or BRAF mutations, and melanoma with NRAS or BRAF mutations. Combination expansion cohorts are planned to evaluate DCC-3116 in combination with trametinib.
