A Multicenter, Open-Label Phase 1 Study of DS-1205c in Combination With Osimertinib in Subjects With Metastatic or Unresectable EGFR-Mutant Non-Small Cell Lung Cancer

This study has two parts: dose escalation and dose expansion. The primary objectives are: - For Dose Escalation, to assess the safety and tolerability of DS-1205c when combined with osimertinib in the study population and to determine the recommended dose for expansion of DS-1205c when combined with osimertinib in the study population - For Dose Expansion, to assess the safety and tolerability of DS-1205c when combined with osimertinib in the study population In Dose Escalation, after a 7-day run in period (Cycle 0), there will be 21-day cycles (Cycle 1 onward). In Dose Expansion, there will be 21-day cycles. The number of treatment cycles is not fixed in this study. Participants will continue study treatment until they decide not to (withdraw consent), their disease gets worse [progressive disease (PD)], or side effects become unacceptable (unacceptable toxicity).

Primary Outcomes

Measure: Number of participants with dose-limiting toxicities (DLTs) when taking DS-1205c in combination with osimertinib during dose escalation

Time: within 28 days

Description: Categories: during dose escalation, during dose expansion

Measure: Number of participants with clinically significant safety measures when taking DS-1205c in combination with osimertinib

Time: within 36 months

Secondary Outcomes

Description: DS-1205a is the free form of DS-1205c when DS-1205c is administered alone

Measure: Area under the plasma concentration time curve (AUC) for DS-1205a

Time: during Cycle 0 of the dose escalation period (within 28 days)

Measure: Maximum observed analyte concentration (Cmax) of DS-1205a

Time: during Cycle 0 of the dose escalation period (7 days)

Measure: Actual sampling time to reach Cmax (Tmax) of DS-1205a

Time: during Cycle 0 of the dose escalation period (7 days)

Measure: Area under the analyte concentration versus time curve during a dosing interval (AUCtau) of DS-1205a

Time: during Cycle 0 of the dose escalation period (7 days)

Measure: Minimum observed analyte concentration prior to the beginning, or at the end, of a dosing interval (Ctrough) of DS-1205a

Time: during Cycle 0 of the dose escalation period (7 days)

Description: Categories: DS-1205a, osimertinib, and osimertinib active metabolites (AZ5104 and AZ7550)

Measure: Cmax during a dosing interval (Tau) at steady state (Cmax,ss)

Time: during the dose expansion period, within 36 months

Description: Categories: DS-1205a, osimertinib, and osimertinib active metabolites (AZ5104 and AZ7550)

Measure: Plasma concentration of DS-1205a versus time

Time: during the dose expansion period, within 36 months

Description: Categories: DS-1205a, osimertinib, and osimertinib active metabolites

Measure: AUCtau

Time: during the dose expansion period, within 36 months

Description: Objective response rate is calculated as the number of participants with best objective response [complete response (CR) or partial response (PR) determined by Investigator assessment based on Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1], divided by the number of participants in the analysis population.

Measure: Objective response rate (ORR), graded according to RECIST version 1.1

Time: within 36 months

Measure: Change from baseline in size of target lesion(s)

Time: within 36 months

Description: DOR is defined as the time from documentation of tumor response [either CR or PR] to disease progression

Measure: Duration of response (DOR)

Time: within 36 months

Description: DCR is defined as the sum of CR rate, PR rate, and stable disease (SD) rate

Measure: Disease control rate (DCR)

Time: first dose to 36 months

Description: PFS is defined as the time from the date of the first dose to the earlier of the dates of the first objective documentation of radiographic PD, or death due to any cause

Measure: Progression-free survival (PFS)

Time: baseline to objective disease progression or death from any cause (within 36 months)

Measure: Overall survival (OS)

Time: baseline to death from any cause (within 36 months)

Purpose: Treatment

Historical confirmation that the tumor harbors an EGFR mutation known to be associated with EGFR TKI sensitivity (including G719X, exon 19 deletion, L858R, L861Q) or 2. Has experienced clinical benefit from an EGFR TKI, followed by systemic progression (Response Evaluation Criteria in Solid Tumors [RECIST version 1.1] or World Health Organization [WHO]) while on continuous treatment with an EGFR TKI. 4. Is currently receiving, and is able to discontinue erlotinib, gefinitib, or afatinib; or is currently receiving osimertinib at the prescribed 80 mg dose and is able to interrupt osimertinib. --- L858R ---
