DS-1205c was generally safe and well tolerated at all dose levels, but the safety profile of ≤800 mg BID was more favorable than 1200 mg BID. The recommended dose for dose-expansion cohorts of DS-1205c in combination therapy with gefitinib was 800 mg BID.
Eligible subjects must either have evidence of radiological disease progression during treatment with erlotinib, gefitinib, or afatinib without the T790M resistance mutation, or must experience disease progression during osimertinib treatment and no risk factors for QTc prolongation. Preliminary analysis of efficacy data reveals that three patients had stable disease beyond 100 days (RECIST v.1.1). Conclusion Dose escalation is ongoing and updated clinical and biomarker data will be presented.
