Brief Summary:
This is a Phase I, open-label study to assess the safety, tolerability, pharmacokinetics and anti-tumor activity of AZD4635 in Japanese patients with advanced solid malignancies. This study consists of 2 cohorts, Cohort1 and Cohort2. At least 3 or up to 6 evaluable Japanese patients with advanced solid malignancies will be enrolled in Cohort1 and 6 evaluable patients will be enrolled in Cohort2.

Condition or disease Intervention/treatment Phase
Advanced Solid Malignancies Drug: AZD4635 Phase 1

Detailed Description:

Objectives:

Primary objective:

Investigate the safety and tolerability of AZD4635 monotherapy in Japanese patients

Secondary objective:

Characterize the single-dose and multiple-dose plasma pharmacokinetic (PK) parameters of AZD4635 monotherapy Determine the preliminary anti-tumor activity of AZD4645 monotherapy

Overall design:

This is a phase I, open-label study of AZD4635 in Japanese patients with advanced solid malignancies.

The study consists of 2 cohorts, Cohort 1 and Cohort 2. At least 3 or up to 6 evaluable Japanese subjects with advanced solid malignancies will be enrolled in Cohort 1 and 6 evaluable patients will be required for Cohort 2 to confirm the tolerability. The total number of evaluable subjects in each cohort will depend upon available data in each cohort and decision of Safety Review Committee(SRC).

Study Period:

The study is expected to start in June 2019 and end in June 2020.

Number of Subjects:

9 to 12 evaluable subjects will be enrolled in this study to confirm the tolerability.

Treatments and treatment duration:

Subjects will receive AZD4635 once daily (QD). A single dose of AZD4635 will be taken on Cycle 0 Day1 and the subsequent dose of AZD4635 will be taken from Cycle 1 Day 1 until discontinuation criterion is met. A cycle of study treatment will be defined as 21 days of continuous dosing.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. The incidence of Adverse event and SAE [ Time Frame: From the informed consent to 30 days post last dose ]
    Investigate the safety and tolerability of AZD4635

  2. The incidence of Dose-limiting toxicity (DLTs) [ Time Frame: 25 days (Cycle0 and Cycle1) ]
    Investigate the safety and tolerability of AZD4635


Secondary Outcome Measures :
  1. Objective response rate (ORR) [ Time Frame: Tumor assessment is Cycle 4 Day 1 and then on Day 1 of each even numbered cycle (+/-5 days) until disease progression. Expected to be for up to 6 months. ]
    Summarize based on RECIST 1.1 by cohort and overall.

  2. Maximum plasma concentration (Cmax) [ Time Frame: Samples will be collected at pre-specified time points in the single-dose and multiple-dose portion of the study beginning with Cycle 1 Day 1 until last dose. Expected to be for up to 6 months. ]
    Characterize the single-dose and multiple-dose plasma of AZD4635

  3. Disease control rate (DCR) [ Time Frame: Tumor assessment is Cycle 4 Day 1 and then on Day 1 of each even numbered cycle (+/-5 days) until disease progression. Expected to be for up to 6 months. ]
    Summarize based on RECIST 1.1 by cohort and overall.

  4. Area under the plasma concentration-time curve (AUC) [ Time Frame: Samples will be collected at pre-specified time points in the single-dose and multiple-dose portion of the study beginning with Cycle 1 Day 1 until last dose. Expected to be for up to 6 months. ]
    Characterize the single-dose and multiple-dose plasma of AZD4635
