Study Details

Study Description

Brief Summary

In an unbiased CRISPR screen, RIPK1 was identified as a top gene contributing to immunotherapy resistance. In addition, RIPK1 has been reported to drive pancreatic oncogenesis. In murine models, inhibition of RIPK1 kinase activity in the pancreatic tumor microenvironment leads to the replacement of tumor-permissive myeloid infiltrates with innate cells that promote an effective antitumor response by adaptive cells. The investigators hypothesize that inhibition of RIPK1 in human pancreatic cancer subjects will modulate the immune infiltrate to sensitize tumors to checkpoint blockade.

Eligibility Criteria

Criteria

• Ages Eligible for Study: 18 Years and Older
• Sexes Eligible for Study: All
• Accepts Healthy Volunteers: No

Inclusion Criteria:

• Subjects must provide signed, written informed consent.

• Male and female subjects, age >=18 years (at the time consent is obtained). a) Male subjects are eligible to participate if they agree to the following during the study treatment period and for at least 15 days (Part 1) and 120 days (Parts 2-4) after the last dose of study treatment: Refrain from donating sperm, be abstinent from heterosexual or homosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent or must agree to use contraception/barrier: male condom and female partner to use an additional highly effective contraceptive method with a failure rate of <1 percent per year. b) female subjects are eligible to participate if they are not either pregnant or breastfeeding, and at least one of the following conditions applies: is not a woman of childbearing potential (WOCBP), is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of <1 percent per year), with low user dependency during the study treatment period and for at least 15 days (Part 1) and 120 days (Parts 2-4) after the last dose of study treatment and agrees not to donate eggs (ova, oocytes) for the purpose of reproduction during this period. The investigator should evaluate the effectiveness of the contraceptive method in relationship to the first dose of study treatment. Hormonal contraception may be susceptible to interaction with the study drug, which may reduce the efficacy of the contraceptive method. Therefore, a barrier method is also required for subjects using a hormonal option (including hormonal intrauterine device [IUD], oral contraceptive pills/ patch/ vaginal inserts, and hormonal implants) and both highly effective methods of contraception should be utilized during the treatment period and for at least 15 days (Part 1) and 120 days (Parts 2-4) after the last dose of study treatment.If a highly effective non-hormonal method is used, then only one method of contraception is required (by a female participant or partner of a male participant; in either situation the male partner must still use a male condom in addition) during the treatment period and for at least 15 days (Part 1) and 120 days (Parts 2-4) after the last dose of study treatment. A WOCBP must have a negative highly sensitive pregnancy test (urine or serum) as required by local regulations) within 24 hours before the first dose of study intervention. If a urine test cannot be confirmed as negative (e.g., an ambiguous result), a serum pregnancy test is required. In such cases, the subject must be excluded from participation if the serum pregnancy result is positive. If the subject hasn't been on an acceptable method of contraception for at least 2 weeks prior to start of therapy, pregnancy testing must be done weekly for the first month of treatment.

7. Primary Outcome

Title	Percentage of Participants Achieving Complete Response (CR) or Partial Response (PR) Based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 Criteria-Part 3
Description	A participant's disease status and determination of disease progression at post Baseline visits was to be evaluated by the local investigator's assessments by RECIST version 1.1. The overall response rate (ORR)-CR and PR was to be determined by the investigator assessment of the participants computed tomography (CT) or magnetic resonance imaging (MRI) using RECIST version 1.1 criteria for target lesions. ORR is defined as the percentage of participants with a best overall confirmed CR or PR at any time as per disease-specific criteria. PR is when there is at least 30 percent decrease in sum of the longest diameter of the target lesions. Complete Response is when there is disappearance of all non-nodal target lesions, with the short axes of any target lymph nodes reduced to <10 millimeters (mm).
Time Frame	Until response, disease progression, initiation of another anticancer therapy or death whichever is earlier (maximum follow-up up to 2 years 90 days)

Title	Best Overall Response (BOR) Rate-Part 2
Description	Best overall response is defined as the best unconfirmed response (CR > PR > SD [or non-CR/non-PD] > PD] > NE) from treatment start date until disease progression or initiation of new anti-cancer therapy, whichever is earlier, as assessed by the investigator per RECIST 1.1 Criteria. The BOR rate is defined as the percentage of participants with each best unconfirmed response category. Participants with unknown or missing responses were treated as non-responders, i.e., these participants were included in the denominator when calculating percentages of response.
Time Frame	Until response, disease progression, initiation of another anticancer therapy or death whichever is earlier (maximum follow-up up to 2 years and 90 days)
