Phase I Study of AZD5363 + Olaparib + Durvalumab in Patients With Advanced or Metastatic Solid Tumor Malignancies

Study Overview
=================
Brief Summary
-----------------
This is a Phase 1 dose-escalation study to evaluate the safety and tolerability of combination treatment of AZD5363 + Olaparib + Durvalumab and to determine the RP2D in patients with advanced or metastatic solid tumor malignancies. The purpose of this trial is to determine if combination treatment of drugs, Olaparib, AZD5363 and Durvalumab has beneficial effects in advanced or metastatic cancers and to determine the effects it has on patients and their cancer. Primary Objectives • To evaluate the safety and tolerability of combination treatment AZD5363 + Olaparib + Durvalumab and determine the Maximum Tolerated Dose (MTD), Dose-Limiting Toxicities (DLTs), and Recommended Phase 2 Dose (RP2D) for patients with advanced or metastatic solid tumor malignancies. Secondary Objectives To determine the pharmacodynamics (PDn) of combination treatment AZD5363 + Olaparib + Durvalumab in patients with advanced or metastatic solid tumor malignancies To describe anti-tumor response using immune RECIST of combination treatment AZD5363 + Olaparib + Durvalumab in patients with advanced or metastatic solid tumor malignancies Exploratory Objectives To evaluate anti-tumour response using RECIST v1.1 for combination treatment AZD5363 + Olaparib + Durvalumab in patients with advanced or metastatic solid tumor malignancies To explore molecular correlates of the relationship between mutations in Akt/ PIK3CA/PTEN pathway and response to AZD5363 +Olaparib+ Durvalumab To understand the role of tumour microenvironment in regulation of intratumoral immune regulators (i.e. T-regulatory cells) in improving response to Durvalumab To understand the role of AZD5363 as an immunomodulator To evaluate the role of PD-1 and PDL-1 immunohistochemical and tumour MMR status in predicting response to immune check point inhibitors.

Detailed Description
-----------------
This study is divided into 3 different periods: Screening, Treatment, and End of Treatment Before taking the treatment, patients will have some tests and procedures done to make sure they are eligible for the study (Screening). Then they will enter the Treatment period, where Durvalumab, Olaparib and AZD5363 will be administered to them. If they stop taking your study medication for any reason, an End of Treatment visit will be conducted within 30 days after the last doze of study medication.

Eligibility Criteria
-----------------
Inclusion Criteria: All patients must sign an informed consent in accordance with local institutional guidelines. Age >= 21 Histologically confirmed advanced or metastatic solid tumors who have radiological evidence of progressive disease on study entry and at least 2 measurable lesions, that is deemed unlikely to benefit from further conventional therapy, or for which no standard therapy is available. Although optional, where practicable and safe, all effort should be made by the investigator to obtain serial tumour biopsies from patients enrolled. Provision of an archived tumour tissue block (or at least 10 newly cut unstained slides) where such samples exist in a quantity sufficient to allow for analysis Any number of prior chemotherapy regimens will be allowed and may include biologics Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 to 1; Patients must have adequate bone marrow function and organ function within 2 weeks of study treatment; Adequate hematologic function defined as: (i) platelets >= 100 x 109/L in dose escalation phase, (ii) hemoglobin >= 6.21 mmol/L or 10 g/dL, (iii) ANC >= 1.5 x 109/L, (iv) WBC >= 3.0 x 109/L. Up to 5% deviation is tolerated. Transfusions and growth factors are allowed prior to and throughout the study. Hepatic function: bilirubin < 1.5 times the upper limit of normal (ULN), ALT and AST < 2.5 times ULN. For patients with hepatic metastasis ALT and AST < 5 times ULN is permitted. Up to 10% deviation is acceptable. Adequate renal function: estimated creatinine clearance of >= 60 mL/min, calculated using the formula of Cockcroft and Gault: (140-Age) • Mass (kg)/(72 • creatinine mg/dL); multiply by 0.85 if female. Amylase and lipase <= 1.5 x ULN; Alkaline phosphatase limit <= 2.5 x ULN (<= 5 x ULN for patients with liver involvement of their cancer); International normalization ratio (INR) (if not on anticoagulation therapy) and partial thromboplastin time (PTT) <= 1.5 x ULN; Normal TSH and ACTH Females of childbearing potential who are sexually active with a non sterilized male partner must use at least 2 highly effective method of contraception from the time of screening and must agree to continue using such precautions for 180 days after the last dose of durvalumab + any drug combination therapy or 90 days after the last dose of durvalumab monotherapy. Non-sterilized male partners of a female patient must use male condom plus spermicide throughout this period. Cessation of birth control after this point should be discussed with a responsible physician. Not engaging in sexual activity for the total duration of the drug treatment and the drug washout period is an acceptable practice; however, periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. Female subjects should also refrain from breastfeeding throughout this period. Acceptable methods of contraception are as below: Established use of oral, injected or implanted hormonal methods of contraception. Placement of an intrauterine device or intrauterine system. Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository. Male partner sterilisation (with the appropriate post-vasectomy documentation of the absence of sperm in the ejaculate). True abstinence It is not known whether AZD5363 has the capacity to affect the metabolism of hormonal contraceptives, so hormonal contraception should also be combined with a barrier method of contraception or patients must have evidence of non-child-bearing potential by fulfilling one of the following criteria at screening: Post-menopausal: defined as aged more than 50 years and amenorrhoeic for at least 12 months following cessation of all exogenous hormonal treatments. Documentation of irreversible surgical sterilisation by hysterectomy, bilateral oophorectomy or bilateral salpingectomy, but not tubal ligation Non-sterilized males who are sexually active with a female partner of childbearing potential must use a male condom plus spermicide from screening through 180 days after receipt of the final dose of durvalumab + any drug combination therapy or 90 days after receipt of the final dose of durvalumab monotherapy. Not engaging in sexual activity is an acceptable practice; however, occasional abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception. Male patients are required to use barrier methods of contraception and refrain from sperm donation throughout the study and for 180 days after the last dose of study drug. Male patients wishing to father children should be advised to arrange for freezing of sperm samples prior to the start of study treatment. Breastfeeding women are also excluded from study entry. At time of registration, if the patient has had previous treatment it must have been at least 4 weeks since major surgery or radiation therapy; four weeks from any other previous anti-cancer therapy including biologics. Patients must have recovered from their treatment-related events to <=G1 with the exception of alopecia and neuropathy (<= G2 sufficient).
