A Study to Evaluate the Effectiveness and Safety of Setidegrasib, Given With Either mFOLFIRINOX or NALIRIFOX Chemotherapies, in People With Pancreatic Cancer

Pancreatic cancer is difficult to diagnose early. By the time people have been diagnosed, the cancer has usually spread to other parts of the body (metastatic). The standard treatment is chemotherapy, but other treatments are needed to improve outcomes in people with pancreatic cancer. The first treatment that people usually receive is chemotherapy. At the time this study started, some of the main standard chemotherapies for pancreatic cancer were mFOLFIRINOX or NALIRIFOX.

Genes give your body instructions on how to make proteins. Proteins are needed to keep the body working properly. Many types of cancer are caused by changes in certain genes, making them faulty. Many people with pancreatic cancer have a faulty KRAS gene. One such change in the KRAS gene is called a G12D mutation. Researchers are looking for ways to stop the actions of abnormal proteins made from the KRAS G12D mutation.

This study is about setidegrasib given with chemotherapy in people with pancreatic cancer who have the KRAS G12D mutation. Before setidegrasib can become an approved treatment, clinical studies need to be completed to understand how it works and how safe it is.

The main aim is to learn if people who are given setidegrasib with chemotherapy live for longer than people who are given placebo with chemotherapy. Other aims are to learn if setidegrasib delays the cancer and symptoms returning, how the body processes setidegrasib, and its safety, when given with chemotherapy.

People in this study will be adults with metastatic pancreatic cancer with the G12D mutation in their KRAS gene. Surgery or radiotherapy will not be an option to cure their cancer.

People cannot take part if the cancer cells have spread to the thin tissue covering the brain and spinal cord (leptomeningeal disease), have symptoms of cancer in the brain or nervous system, or have recently had some other cancers that required treatment.

In this study, people are given either setidegrasib with mFOLFIRINOX or NALIRIFOX chemotherapy, or a placebo with mFOLFIRINOX or NALIRIFOX chemotherapy. Whether people receive setidegrasib or placebo is decided by chance. The study doctor decides which chemotherapy (mFOLFIRINOX or NALIRIFOX) people receive. People will only receive NALIRIFOX chemotherapy (with setidegrasib or placebo) after the safety of setidegrasib with NALIRIFOX chemotherapy has been confirmed in another ongoing setidegrasib study. All of the study treatments are given slowly through a tube into a vein (infusion). People will continue to receive study treatment until their cancer gets worse, they can't tolerate the study treatment, they start other cancer treatment, they or the doctor decides the person should stop receiving study treatment, or sadly they pass away. There will be safety checks at each visit, and the doctors will continue to check for medical problems and people's wellbeing throughout the study.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Participant has histologically confirmed metastatic pancreatic ductal adenocarcinoma (PDAC) with documented Kirsten rat sarcoma viral oncogene homolog (KRAS) G12D mutation based on local or central testing (confirmation of a participant's positive KRAS G12D mutation result must be available prior to randomization).
  • Participant has no option for surgical resection or radiotherapy with curative intent.
  • Participant consents to and provides a baseline tumor tissue specimen for the study during screening. The sample must meet the requirements described in the laboratory manual and the tumor sample guidance.

The laboratory values prior to the initiation of the first dose of setidegrasib/placebo (or mFOLFIRINOX/NALIRIFOX, if chemotherapy is administered during the screening period) should be used to determine eligibility. Participants who receive mFOLFIRINOX/NALIRIFOX during the screening period must meet these criteria within 7 days prior to the start of on-treatment chemotherapy (i.e., C1D1).
  • Participant agrees not to participate in another interventional study while receiving study intervention in the present study (participant who is currently in the follow-up period of an interventional clinical trial is allowed).

Exclusion criteria

  • Participant has neuroendocrine, acinar pancreatic carcinoma or pancreatic cancer with squamous/adenosquamous features.
  • Participant has another prior malignancy active (i.e., requiring treatment, including hormonal therapies, or intervention) within the previous 2 years different from the primary malignancy for this study, except for local malignancies that have been apparently cured, such as basal or squamous cell skin cancer, superficial bladder cancer or carcinoma in situ of the cervix or breast, which are allowed.
  • Participant has chronic inflammatory bowel disease, bowel obstruction and/or severe uncontrolled diarrhea.
  • Participant has peripheral sensory neuropathy with functional impairment.
  • Participant has ascites and/or pleural effusion that require invasive interventions within 30 days prior to randomization or have an indwelling drainage catheter.

  • Participant has received any prior systemic therapy for their metastatic PDAC (except with up to 2 doses [i.e., 28 days; 1 cycle] of mFOLFIRINOX or NALIRIFOX during the screening period. If a participant received [neo]adjuvant chemotherapy, tumor recurrence or disease progression must have occurred ≥ 6 months after completing the last dose of the [neo]adjuvant therapy).

Participants rate items on a four-point scale, with 1 as "not at all" and 4 as "very much." For functional scales, higher scores indicate better functioning, while for symptom scales/items, higher scores indicate worse symptoms.

Each domain comprises 5 severity levels (no problems, slight problems, moderate problems, severe problems, extreme problems). The general visual analog scale records the respondent's self-rated health status on a vertical graduated (0 = the worst health a participant can imagine to 100 = the best health a participant can imagine) visual analogue scale. Responses to the 5 items will also be converted to a weighted health state index (utility score) based on values derived from general population samples.

    The PGIC is a single-item questionnaire that asks participants to provide the overall self-assessment of change in their disease on a 7-point scale ranging from "very much worse" to "very much better" as compared to the participant starting the study treatment. Only PGIC questions assessing pain and overall status will be collected.

  17. Change from baseline in Patient Global Impression of Severity PGIS

    Time frame: Up to 3.5 years

    The PGIS is a single-item questionnaire that asks participants to provide the overall self-assessment of their disease severity on a 4-point scale for the past week, with 1 as "None" and 4 as "Severe". Only PGIS questions assessing pain and overall status will be collected.
