About

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.

Full 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.

Patients must have either at least one lesion that can be evaluable using RECIST v1.1 or patients with mCRPC must have measurable prostate specific antigen above normal limits (per local ranges)
Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
Normotensive or well controlled blood pressure, with or without current antihypertensive treatment
Females of child-bearing potential must use 2 highly effective methods of contraception
Male patients should be willing to use barrier contraception

Major Exclusion Criteria:

Any investigational medicinal product or other systemic anticancer treatment within at least 4 weeks prior to the first dose of study treatment, or within 8 weeks after immunotherapy or other long half-life antibody therapy, whichever is the most appropriate and as judged by the Investigator.
Evidence of recent or significant cardiovascular disease
Unresolved toxicities from prior therapy greater than CTCAE Grade 1 at starting study treatment
History of seizures, CNS tumors or CNS metastasis
Active or prior documented autoimmune or inflammatory disorders within the past 3 years to the start of treatment
Patients with prior ≥ Grade3 immune-mediated reactions
Evidence of severe or uncontrolled systemic diseases
Inadequate bone marrow reserve or organ function
Refractory nausea and vomiting, chronic gastrointestinal diseases, or previous significant bowel resection that would preclude adequate absorption of AZD4635
History of hypersensitivity to AZD4635 or drugs with a similar chemical structure or class to AZD4635
Judgment by the Investigator that the patient should not participate in the study
