Description

Summary

This phase I/II trial studies the side effects and best dose of M3814 and to see how well it works when given together with radiation therapy in treating patients with pancreatic cancer that cannot be removed by surgery and has not spread to other parts of the body (localized). M3814 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Giving M3814 and hypofractionated radiation therapy together may work better than radiation therapy alone in the treatment of patients with localized pancreatic cancer.

Official Title

A Phase 1/2 Study of M3814 (Peposertib) in Combination With Hypofractionated Radiotherapy for the Treatment of Locally Advanced Pancreatic Adenocarcinoma

Details

PRIMARY OBJECTIVES: I. To evaluate the safety and tolerability of M3814 (peposertib) in combination with hypofractionated radiotherapy in patients receiving treatment for locally advanced pancreatic adenocarcinoma (LAPC). (Phase I) II. To determine the difference in progression free survival (PFS) between patients with LAPC treated with hypofractionated radiotherapy in combination with M3814 (peposertib) as compared to patients treated with hypofractionated radiotherapy alone. (Phase II) SECONDARY OBJECTIVES: I. To observe and record anti-tumor activity. (Phase I) II. To evaluate plasma pharmacokinetic (PK) profiles of M3814 (peposertib) in patients receiving hypofractionated radiotherapy. (Phase I) III. To compare the 2-year overall survival (OS) rate of patients treated with hypofractionated radiotherapy plus M3814 (peposertib) to that of those treated with hypofractionated radiotherapy alone. (Phase II) IV. To compare the objective response rate (ORR) by imaging of patients treated with hypofractionated radiotherapy plus M3814 (peposertib) to that of those treated with hypofractionated radiotherapy alone. (Phase II) V. To compare the disease control rate in patients treated with hypofractionated radiotherapy plus M3814 (peposertib) as compared to those patients treated with hypofractionated radiotherapy alone. (Phase II) VI. To explore gene signature patterns in baseline patient tumor tissues that may suggest response to the combination of M3814 (peposertib) and radiotherapy, as identified on whole exome sequencing and ribonucleic acid (RNA) sequencing (seq). (Phase II) EXPLORATORY OBJECTIVE: I. To explore changes in gene signature induced by M3814 (peposertib) and hypofractionated radiotherapy treatment as identified in analysis of cell-free deoxyribonucleic acid (DNA) from the peripheral blood. (Phase II) OUTLINE: This is a phase I, dose-escalation study of M3814 followed by a phase II study. PHASE I: Patients undergo hypofractionated radiation therapy for 5 fractions every other day (QOD) over 2 weeks and receive M3814 orally (PO) once daily (QD) for 14 days in the absence of disease progression or unacceptable toxicity. PHASE II: Patients are randomized to 1 of 2 groups. GROUP I: Patients undergo hypofractionated radiation therapy for 5 fractions QOD over 2 weeks and receive M3814 PO QD for 14 days in the absence of disease progression or unacceptable toxicity. GROUP II: Patients undergo hypofractionated radiation therapy for 5 fractions QOD over 2 weeks and receive placebo PO QD for 14 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, and then every 3 months for up to 2 years.

  • Patients must have locally advanced pancreatic cancer according to National Comprehensive Cancer Network (NCCN) Guidelines (Version 1.2020) on CT scan performed within 21 days of registration. Locally advanced disease is defined as any of the following:
  • For head or uncinate process tumors:
  • Solid tumor contact with superior mesenteric artery > 180 degrees
  • Solid tumor contact with the celiac axis > 180 degrees
  • Solid tumor contact with the common or proper hepatic arteries > 180 degrees or
  • For pancreatic body or tail tumors:
  • Solid tumor contact of > 180 degrees with the superior mesenteric artery or celiac axis
  • Solid tumor contact with the celiac axis and aortic involvement or
  • Unreconstructible superior mesenteric vein or portal vein due to tumor involvement or occlusion (can be due to tumor or bland thrombus)
  • Age >= 18 years. Because no dosing or adverse event data are currently available on the use of M3814 (peposertib) in combination with hypofractionated radiation in patients < 18 years of age, children are excluded from this study, but will be eligible for future pediatric trials
  • Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)
  • Leukocytes >= 4,000/mcL
  • Absolute neutrophil count >= lower limits of normal (LLN)
  • Hemoglobin >= 9 g/dL
  • Platelets >= LLN
  • Total bilirubin =< 2.0 x institutional upper limit of normal (ULN)
  • Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase [SGPT]) =< 3 x institutional ULN
  • Creatinine =< 1.5 x institutional ULN
  • Glomerular filtration rate (GFR) >= 51 mL/min/1.73 m2

  • Patients who cannot discontinue concomitant medications or herbal supplements that are strong inhibitors or strong inducers of cytochrome P450 (CYP) isoenzymes CYP3A4/5, CYP2CP, and CYP2C19. Concomitant use of CYP1A2, CYP2B6, and CYP3A4/5 substrates with a narrow therapeutic index are also excluded. Patients may confer with the study doctor to determine if alternative medications can be used. The following categories of medications and herbal supplements must be discontinued for at least the specified period of time before the patient can be treated:
  • Strong inducers of CYP3A4/5, CYP2C9 and CYP2C19: >= 3 weeks prior to study treatment
  • Strong inhibitors of CYP3A4/5, CYP2C9 and CYP2C19: >= 1 week prior to study treatment
  • Substrates of CYP1A2, CYP2B6, and CYP3A4/5 with a narrow therapeutic index: >= 1 day prior to study treatment
  • Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
  • Patients who cannot discontinue concomitant proton-pump inhibitors (PPIs). Patients may confer with the study doctor to determine if such medications can be discontinued. These must be discontinued >= 5 days prior to study treatment. Patients do not need to discontinue calcium carbonate. H2 blockers and antacids are allowed.

  • Patients with uncontrolled intercurrent illness
  • Patients with psychiatric illness/social situations that would limit compliance with study requirements
  • Pregnant women are excluded from this study because M3814 (peposertib) is a DNA-protein kinase (PK) inhibitor with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with M3814 (peposertib), breastfeeding should be discontinued if the mother is treated with M3814 (peposertib)
  • Patients with a history of malignancy within 3 years of the screening visit. Patients with cutaneous carcinomas or in-situ carcinoma will be considered for study entry on a case-by-case basis
