Details and patient eligibility


Researchers are looking for a better way to treat people with solid tumors. Before a treatment can be approved for people to take, researchers do clinical trials to better understand its safety and how it works.

In this trial, the researchers want to learn about regorafenib taken together with nivolumab in a small number of participants with different types of tumors. These include tumors in the head and neck, the esophagus, the pancreas, the brain, and the biliary tract. The biliary tract includes gall bladder and bile ducts.

The trial will include about 200 participants who are at least 18 years old. All of the participants will take 90 mg of regorafenib as a tablet by mouth. The dose of regorafenib can be adjusted up to 120 mg or down to 60 mg by the doctor based on how well a participant tolerates treatment. All of the participants will receive 480 milligrams (mg) of nivolumab through a needle put into a vein (IV infusion).

The participants will take treatments in 4-week periods called cycles. They will take regorafenib once a day for 3 weeks, then stop for 1 week. In each cycle, the participants will receive nivolumab one time. These 4-week cycles will be repeated throughout the trial. The participants can take nivolumab and regorafenib until their cancer gets worse, until they have medical problems, or until they leave the trial. The longest nivolumab can be given is up to 2 years.

During the trial, the doctors will take pictures of the participants' tumors using CT or MRI and will take blood and urine samples. The doctors will also do physical examinations and check the participants' heart health using an electrocardiogram (ECG). They will ask questions about how the participants are feeling and if they have any medical problems.

Inclusion criteria

  • Histologically confirmed selected recurrent or metastatic solid tumor types that have progressed after treatment with standard therapies and for which there are no curative intent surgery or chemoradiation.

  • Cohort 1: subjects with HNSCC (Head and neck squamous-cell carcinoma) who have not received prior PD-1/PD-L1 inhibitor therapy.

  • Cohort 2: subjects with HNSCC who have progressed on or after prior systemic therapy, at least one of which included a PD-1/PD-L1 inhibitor alone or in combination with chemotherapy.

  • Cohort 3: subjects with ESCC (Esophageal Squamous Cell Carcinoma) who progressed on or after platinum and/or fluoropyrimidine based regimen.

  • Cohort 4: subjects with PDAC (Pancreatic ductal adenocarcinoma) who have progressed on or after gemcitabine or fluoropyrimidine based regimens.

  • Cohort 5: subjects with BTC (Biliary tract carcinoma) (intrahepatic or extrahepatic cholangiocarcinoma or gall bladder cancer) who have progressed on gemcitabine or fluoropyrimidine or platinum therapy or a combination of these agents.

  • Cohort 6: subjects with Grade IV GBM (Glioblastoma multiforme) or Grade III AA (Anaplastic astrocytoma) (World Health Organization [WHO] criteria) with unequivocal first progression after surgery followed by radiotherapy and temozolomide.

  • Documented HPV (Human papilloma virus) / p16 status for oropharyngeal cancer.

  • Capable of giving signed informed consent, including compliance with the requirements and restrictions listed in the informed consent form (ICF) and in the protocol.

  • Adult participants of legal maturity (18 years or older).

  • Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) 0 to 1.

  • Adequate hematologic and organ function as assessed by the following laboratory tests performed within 7 d before start of study treatment including:

    • Total bilirubin ≤1.5 x the upper limit of normal (ULN). Total bilirubin (≤3 x ULN) is allowed if Gilbert's syndrome is documented
    • Alanine transaminase (ALT) and aspartate aminotransferase (AST) ≤3 x ULN (≤5 x ULN for participants with liver involvement of their cancer)
  • Measurable disease by baseline CT or MRI per RECIST 1.1 or RANO.

  • Participants must consent to provide recent biopsy/tumor tissue of a primary tumor lesion or from metastases (e.g. liver, lung) for HNSCC (IO treated) for Stage 1 and 2 and in HNSCC (IO naïve) cohort for Stage 2.

  • Anticipated life expectancy greater than 3 months.

  • Be able to swallow and absorb oral tablets.

Exclusion criteria

  • Presence of symptomatic central nervous system (CNS) metastases, leptomeningeal metastases or spinal cord compression. Previously-treated lesions should be stable for at least 6 weeks prior to study entry.

  • Participants with a condition requiring systemic treatment with either corticosteroids (>10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days of start of study treatment.

  • Prior therapy with PD-1/PD-L1 or cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitors, or any form of immunotherapy to treat cancer (except cohort 2).

  • Cohort 2: More than one prior therapy with PD-1/PD-L1 or CTLA-4 inhibitors, or any other form of immunotherapy to treat cancer.

  • ESCC:

    • patients with apparent tumor invasion on organs located adjacent to the esophageal disease (e.g., the aorta or respiratory tract).
    • patients who have previously received taxane agents for recurrent/metastatic cancer.
  • GBM/AA

    • Primary tumors localized to the brainstem or spinal cord.
    • Presence of diffuse leptomeningeal disease or extracranial disease.

  • Participants who have known dMMR/MSI-H cancers or NTRK (tropomyosin receptor kinase) fusions.

  • Prior therapy with regorafenib.

  • Systemic anti-cancer treatment within 14 days or less than 5 half-lives (whichever is shorter) of the first dose of study treatment.
