NCT05411094 | RECRUITING | Locally Advanced Pancreatic Carcinoma

Testing the Safety of the Anti-Cancer Drugs Durvalumab and Olaparib During Radiation Therapy for Locally Advanced Unresectable Pancreatic Cancer
Sponsor:

National Cancer Institute (NCI)

Brief Summary:

This phase I trial tests the safety and tolerability of olaparib in combination with durvalumab and radiation therapy in patients with pancreatic cancer that has spread to nearby tissue or lymph nodes (locally advanced) and cannot be removed by surgery (unresectable). Olaparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. The combination of targeted therapy with olaparib, immunotherapy with durvalumab and radiation therapy may stimulate an anti-tumor immune response and promote tumor control in locally advanced unresectable pancreatic cancer.

Detailed Description:

PRIMARY OBJECTIVE: I. Determine the maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D) of olaparib in combination with durvalumab and radiation therapy (RT). SECONDARY OBJECTIVES: I. To observe and record anti-tumor activity. II. Correlate response with the circulating frequency and diversity of T cells within the peripheral blood. III. Evaluate the safety and toxicity of olaparib in combination with durvalumab and RT. EXPLORATORY OBJECTIVES: I. Evaluate the genetic and clinicopathologic markers of response and resistance including prior receipt of platinum therapy. II. To correlate response with baseline tumoral immune infiltrate. OUTLINE: This is a dose-escalation study of olaparib in combination with fixed dose durvalumab and radiation therapy. Patients receive olaparib orally (PO) twice daily (BID) on days 1-28 and durvalumab intravenously (IV) over 55-65 minutes on day 1 of each cycle. Beginning cycle 2, patients also undergo radiation therapy daily on weekdays for 3 weeks. Chemotherapy and immunotherapy cycles repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity. Patients undergo radiologic evaluation and collection of blood samples throughout the study. Patients may undergo optional collection of buccal samples and optional biopsy at screening and/or on study. After completion of study treatment, patients are followed up at 90 days and every 12 weeks thereafter for two years on until death, whichever occurs first.

To be eligible for this trial, patients should be class 2B or better.
      • * The effects of durvalumab and olaparib on the developing human fetus are unknown. For this reason and because radiotherapy used in this trial is known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception prior to study entry, for the duration of study participation, and for 6 months after the last dose of study treatment. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Male patients should not donate sperm throughout the period of taking olaparib and for 6 months following the last dose of olaparib. All females of childbearing potential (not surgically sterilized, and between menarche and 1 year post menopause) must have a negative screening pregnancy test.
      • * Ability to understand and the willingness to sign a written informed consent document. Participants with impaired decision-making capacity who have a legally-authorized representative (LAR) and/or family member available will also be eligible.
      Exclusion Criteria
      • * Patients who have had prior upper abdominal radiotherapy prior to entering the study.
      • * Patients who have not recovered from grade \>= 2 adverse events (AEs) due to prior anti-cancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria.
      • * Patients with grade \>= 2 neuropathy will be evaluated on a case-by-case basis after consultation with the Study Physician.
      • * Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the Study Physician.
      • * Major surgical procedure within 28 days prior to enrollment. Note: Local surgery of isolated lesions for palliative intent is acceptable. Laparoscopy and/or laparotomy without resection does not constitute a major surgical procedure.
      • * Current or prior use of immunosuppressive medication within 14 days before the first dose of durvalumab. The following are exceptions to this criterion
        • * Intranasal, inhaled, topical steroids, or local steroid injections (e.g., intra articular injection)
        • * Systemic corticosteroids at physiologic doses not to exceed \<\<10 mg/day\>\> of prednisone or its equivalent
        • * Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication)
        • * Receipt of live attenuated vaccine within 30 of planned start of study therapy. Note: Patients, if enrolled, should not receive live vaccine whilst receiving investigational product (IP) and up to 30 days after the last dose of IP.
        • * Patients who are receiving any other investigational agents.
        • * History of allergic reactions attributed to compounds of similar chemical or biologic composition to olaparib or durvalumab.
        • * Patients with any other significant condition(s) that would make this protocol unreasonably hazardous.
        • * Patients receiving any medications or substances that are inhibitors or inducers of CYP3A4/5 are ineligible. 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. The required washout period prior to starting olaparib is 5 weeks for enzalutamide or phenobarbital, and 3 weeks for other agents.
        • * Must not have prior history of organ transplantation, allogeneic transplantation, or double umbilical cord transplantation.
        • * Must not have germline BRCA1 or BRCA2 mutation.
        • * Prisoners or subjects who are involuntarily incarcerated, or compulsorily detained for treatment of either a psychiatric or physical (e.g. infectious disease) illness would be excluded.
        • * Patients must not have previously received anti-PD-1/PD-L1 antibodies or PARP inhibitor for treatment of this cancer.
        • * Patients must not have myelodysplastic syndrome/acute myeloid leukemia or features suggestive of myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML).
        • * Pregnant women are excluded from this study because olaparib is a small molecule agent 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 olaparib, breastfeeding should be discontinued if the mother is treated with olaparib. These potential risks may also apply to other agents used in this study.
        • * Participants must not have an active, known or suspected autoimmune disease which may affect vital organ function or has/may require systemic immunosuppressive therapy for management. Participants with inflammatory disorders (including inflammatory bowel disease \[e.g., colitis or Crohn's disease\], diverticulitis \[with the exception of diverticulosis\], systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome \[granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc.\]) are also excluded with the exception of the following
          • * Patients with vitiligo or alopecia.
          • * Patients with hypothyroidism (e.g. following Hashimoto syndrome) stable on hormone replacement.
          • * Any chronic skin condition that does not require systemic therapy.
          • * Patients without active disease in the last 5 years may be included but only after consultation with the study physician.
          • * Patients with celiac disease controlled by diet alone.
          • * Participants with type I diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger (such as celiac disease controlled by diet) are permitted to enroll. Patients without active disease for 5 years may also be enrolled after consultation with the study monitor or sponsor.
          • * Patients must not have serious, uncontrolled medical disorder, non-malignant systemic disease. Examples include but are not limited to active heart disease including symptomatic heart failure (New York Heart Association \[NYHA\] class 3 or 4), unstable angina pectoris, uncontrolled cardiac arrhythmia or interstitial lung disease, uncontrolled major seizure disorder, unstable spinal cord compression, superior vena cava syndrome, extensive interstitial bilateral lung disease on high resolution computed tomography (HRCT) scan.
          • * Must not have known active inflammatory gastrointestinal disease, chronic diarrhea (other than exocrine insufficiency controlled by enzyme replacement therapy), short gut syndrome, or other conditions that would limit the absorption of the study drug. Patient must be able to swallow and retain an oral medication.
          • * Active infection including tuberculosis (clinical evaluation that includes clinical history, physical examination and radiographic findings, and tuberculosis \[TB\] testing in line with local practice), hepatitis B (known positive HBV surface antigen \[HbsAg\] result), or hepatitis C.
          • * In addition, the patient must not have resting electrocardiogram (ECG) indicating uncontrolled, potentially reversible cardiac conditions, as judged by the investigator (e.g., unstable ischemia, uncontrolled symptomatic arrhythmia, congestive heart failure, corrected QT interval by Fredericia \[QTcF\] prolongation \> 500 ms, electrolyte disturbances, etc.), or patients with congenital long QT syndrome.
