Summary

This phase I/II trial studies the side effects and best dose of avelumab with M6620 in treating patients with deoxyribonucleic acid (DNA) damage repair (DDR) deficient solid tumors that have spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable). DDR deficiency refers to a decrease in the ability of cells to respond to damaged DNA and to repair the damage, which can be caused by genetic mutations. Immunotherapy with monoclonal antibodies, such as avelumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. M6620 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving avelumab together with M6620 may help to control DDR deficient metastatic or unresectable solid tumors.

Description

PRIMARY OBJECTIVES:

I. To determine the safety and tolerability of the combination of berzosertib (M6620) and avelumab in patients with DNA damage response (DDR) deficient advanced solid tumors. (Arm A: M6620 + avelumab) II. To establish the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of the combination of M6620 and avelumab in patients with DDR deficient advanced solid tumors. (Arm A: M6620 + avelumab)

SECONDARY OBJECTIVES:

I. To determine the clinical benefit of the combination as defined by clinical benefit rate (CBR) - complete response [CR] + partial response [PR] + stable disease [SD] > 6 months (CR + PR + SD > 6 months). (Arm A: M6620 + avelumab) II. To assess clinical benefit of the combination as defined by objective response rate (ORR), overall survival (OS), duration of response (DoR) and progression free survival (PFS). (Arm A: M6620 + avelumab)

EXPLORATORY OBJECTIVES:

I. To evaluate clinical benefit of the combination of M6620 and avelumab based on specific DDR aberrations. (Arm A: M6620 + avelumab) II. To evaluate clinical benefit of the combination of M6620 and avelumab based on DDR gene expression signatures. (Arm A: M6620 + avelumab) III. To evaluate the impact of treatment on programmed death ligand 1 (PD-L1) expression and immune cell populations. (Arm A: M6620 + avelumab) IV. To assess potential mechanisms of resistance by comparing pre- and on-treatment biopsies in responders and non-responders. (Arm A: M6620 + avelumab) V. To evaluate the pharmacokinetic (PK) and pharmacodynamic (PD) profile of M6620 in combination with avelumab in patients with DDR deficient advanced solid tumors. (Arm A: M6620 + avelumab)

OUTLINE: This is a phase I, dose-escalation study of M6620, followed by a phase II study.

Patients receive avelumab intravenously (IV) over 60 minutes on days 1 and 15, and M6620 IV over 60 minutes on days 1, 8, 15, and 22. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30, 60, and 90 days, then every 12 weeks afterwards.

Variant interpretation for actionability will be performed by PODS
	Subjects with germline defects in DDR genes are eligible for this trial
	The collection of archival tumor tissue (within 1 year prior to study enrollment) will be mandatory. Tumor biopsies on cycle 1 day 15 will be mandatory. Subjects will not be put at undue risk to obtain the biopsy at cycle 1 day 15 (C1D15). A biopsy at C1D15 will not be required if it poses a serious/severe complication risk greater than 2%. All other biopsy time points are not mandatory but will be strongly encouraged where feasible. These include at baseline and at disease progression
	Subjects must have received at least 1 line of systemic therapy in the advanced/metastatic setting. Subjects with diseases without known effective options, and subjects who had declined standard of care therapy prior to study introduction are also eligible
	Subjects enrolling in the dose escalation should have progressed on or be intolerant to all therapies known to confer a clinical benefit. Subjects must not have refused all available therapies
	Subjects who have received prior therapy with immune checkpoint inhibitors (ICIs) are eligible for this trial. Subjects with a standard-of-care option for an immune checkpoint inhibitor are eligible
	Subjects must have measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1, or patients may have bone metastatic disease evaluable by Prostate Cancer Working Group 3 (PCWG3) for subjects with metastatic castration-resistant prostate cancer (CRPC), or according to tumor evaluation criteria best suited and accepted for the tumor type to be evaluated

	Serum creatinine =< 2 X ULN or estimated creatinine clearance >= 30 mL/min according to the Cockcroft-Gault formula
	Female patients of childbearing potential must have a negative serum or urine pregnancy test at screening (and again at baseline just prior to first administration of study drugs)
	Female patients of non-childbearing potential must meet at least 1 of the following
	criteria
	Achieved postmenopausal status, defined as follows: cessation of regular menses for at least 12 consecutive months, with no alternative pathological or physiological cause

	Have medically confirmed ovarian failure All other female patients (including female patients with tubal ligation) are considered to be of childbearing potential
	Women of childbearing potential and fertile men must agree to use adequate contraception when sexually active from signing of the informed consent form for the full study until at least 6 months after the last study drug administration. Patients must agree to utilize 2 reliable and acceptable methods of contraception simultaneously. A man is considered fertile after puberty unless permanently sterile by bilateral orchiectomy. Men taking part in this study are advised not to father a child during and up to 6 months after treatment; prior to treatment, advice should be sought for conserving sperm due to the chance of irreversible infertility as a consequence of treatment. Female partners of childbearing potential from male study patients have to use adequate contraception / birth control between signing of the informed consent and 6 months after the last administration of the study drug if the male study patient is not sterilized. The investigator or a designated associate is requested to advise the patient how to achieve highly effective birth control. Highly effective (failure rate of less than 1% per year) contraception methods, when used consistently and correctly, include
	Combined (estrogen and progestin containing: oral, intravaginal, transdermal) and progestin-only (oral, injectable, implantable) hormonal contraception associated with inhibition of ovulation
	Intra-uterine device or intrauterine hormone-releasing system
	Bilateral tubal occlusion or vasectomized partner (provided that partner is the sole sexual partner and has received medical assessment of the surgical success)
	Sexual abstinence (reliability to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient) Male patients with a female partner of reproductive potential must use a condom and ensure that an additional form of contraception is also used during treatment and until 6 months after last study drug administration. Patients must agree to utilize 2 reliable and acceptable methods of contraception simultaneously
