简要总结
A Phase I, open-label, multicentre, dose-escalation study to investigate the safety, pharmacokinetics and maximum tolerated dose (MTD) of AZD4785 in patients with advanced solid tumours where KRAS may be an important driver of tumour survival.
Part A: Dose escalation in patients with solid tumours to evaluate safety, pharmacokinetics and maximum tolerated dose (MTD). Once the maximum tolerated dose (MTD) is established, a dose expansion cohort may be included in Part A, with up to an additional 6 patients to further explore the PK, safety, tolerability, and preliminary anti-tumour activity of the AZD4785 MTD for confirmation of the recommended phase 2 dose (RP2D).
Part B: Expansion cohort at the selected dose in patients with non-small cell lung cancer (NSCLC) to evaluate PK parameters, safety, tolerability, and preliminary anti-tumour activity of the AZD4785 RP2D as monotherapy in patients with NSCLC. Approximately 20 patients with NSCLC (Two groups of approximately 10 patients each) with NSCLC will be enrolled to Part B. Group 1 patients will have an option to provide tumour biopsies and Group 2 will be required (mandatory) to provide paired tumour biopsies. Overall up to 12 patients in Group 2Part B patients will be required (mandatory) to may provide paired tumour biopsies. A third group of up to 20 patients with other tumour types and/or a potential different schedule may be added based on the results seen in Parts A and B and any other emerging data and may also provide biopsies.
详细描述
This is a First-Time-in-Human (FTIH), Phase 1 study to determine the MTD, recommended Phase 2 dose (RP2D), safety, tolerability, pharmacodynamics, and pharmacokinetics of AZD4785. The study will be conducted in two parts: a dose-escalation phase (Part A)and an expansion phase (Part B). A third group of up to 20 patients with other tumour types and/or a potential different schedule may be added based on the results seen in Parts A and B and any other emerging data.
AZD4785 will be given as an IV infusion over 1 hour, initially in 3 loading doses during the first week and then weekly thereafter. The loading doses will be given on Days 1, 3, and 5 of the first week and weekly thereafter on Days 8, 15, and 22 of 28 Day cycles. In subsequent cycles AZD4785 will be administered on Days 1, 8, 15, and 22 until disease progression, intolerable toxicity, or discontinuation criteria have been met.
Once the MTD is established, a dose expansion cohort may be included in Part A, with up to 6 additional patients to explore the PK, safety, tolerability, and preliminary anti-tumour activity of the AZD4785 MTD for confirmation of the RP2D. Thereafter, Part B expansion phase will continue to explore PK parameters, safety, tolerability, and preliminary anti-tumour activity of the AZD4785 RP2D as monotherapy in patients with NSCLC. Approximately 20 patients with NSCLC (2 groups of approximately 10 patients each) with NSCLC will be enrolled to Part B. Group 1 patients will have an option to provide tumour biopsies and Group 2 will be required (mandatory) to provide paired tumour biopsies. Overall up to 12 patients in Part B may provide paired tumour biopsies. A third group of up to 20 patients with other tumour types and/or a potential different schedule may be added based on the results seen in Parts A and B and any other emerging data and may also provide biopsies. Up to 12 patients in Part B may provide paired biopsies.

排除标准
- •Patients who have received chemotherapy, radiotherapy, hormonal therapy, immunotherapy or investigational drugs within 21 days or 5 half lives (whichever is shorter) from enrolment.
- •With the exception of alopecia, any unresolved toxicities from prior therapy greater than National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Grade 1 at the time of enrolment.
- •Unresolved immunotherapy-related hepatotoxicity from previous therapy.
- •Major surgery (excluding placement of vascular access) ≤ 21 days from beginning of the enrolment or minor surgical procedures ≤ 7 days. No waiting is required following implantable port and catheter placement.
- •Patients receiving full-dose anti-coagulation therapies.
- •Has active or prior documented autoimmune disease within the past 2 years with the exception of vitiligo, Grave's disease, and/or psoriasis not requiring systemic treatment.
- •Has a history of atypical Haemolytic Uremic Syndrome.
- •Patients with leptomeningeal metastases.
- •Previously untreated brain metastases. Patients who have received radiation or surgery for brain metastases are eligible if therapy was completed at least 3 weeks prior to enrolment and there is no evidence of central nervous system disease progression or mild neurologic symptoms, and no requirement for chronic corticosteroid therapy.
- •Evidence of severe or uncontrolled systemic diseases, including uncontrolled hypertension, active bleeding diatheses, or active infection including hepatitis B, hepatitis C and human immunodeficiency virus (HIV).
- •Any of the following cardiac criteria:
- •Congestive heart failure (CHF) per New York Heart Association (NYHA) classification > Class II.
- •Cardiac ventricular arrhythmias requiring anti-arrhythmic therapy.
- •Unstable angina or new-onset angina.
- •QT interval (QTcF) >470 ms on screening electrocardiogram (ECG) by Fridericia's formula.
- •History of hypersensitivity to active or inactive excipients of AZD4785 or drugs with a similar chemical structure or class to AZD
- •Judgment by the Investigator that the patient should not participate in the study if the patient is unlikely to comply with study procedures, restrictions and requirements.
- •Psychological, familial, sociological, or geographical conditions that do not permit compliance with the protocol.
