Details and patient eligibility

About

The investigators hypothesize that vorolanib in combination with checkpoint inhibitors (pembrolizumab for gastric/gastroesophageal (GE) junction cancers and nivolumab for hepatocellular carcinoma (HCC)) may improve immunotherapy efficacy by overcoming treatment resistance of checkpoint inhibitors in gastrointestinal (GI) cancers.

  • At least 18 years of age.

  • ECOG performance status ≤ 1

  • Normal bone marrow and organ function as defined below:

    • Leukocytes ≥ 2,000/mcL

    • AST(SGOT)/ALT(SGPT) ≤ 2.5 x IULN (≤ 5 x IULN for patients with liver metastases or hepatocellular carcinoma (HCC))
    • Creatinine ≤ 1.5 x IULN OR measured or calculated creatinine clearance ≥ 50 mL/min for patients with creatinine levels > 1.5 x IULN
    • Urine protein ≤1+ or urine protein to creatinine ratio ≤ 1; if UPC ratio is >1 on urinalysis, then 24-hour urine collection from protein must be obtained and level must be <1,000 mg for patient enrollment.
    • aPTT and either INR or PT ≤ 1.5 x ILUN unless participant is receiving anticoagulant therapy as long as PT or aPTT is within therapeutic range of intended use of anticoagulants
  • Patients receiving therapeutic non-Coumadin anticoagulation are eligible, provided they are on a stable dose (per investigator judgment) of anticoagulant.

  • Patients with treated/stable brain metastases, defined as patients who have received prior therapy for their brain metastases and whose CNS disease is radiographically stable at study entry, are eligible. Patients with clinically evident CNS hemorrhage on scans are excluded.

  • Women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry, for the duration of study participation, and for 31 weeks after the last dose of study drug. Should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately.

  • Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable).

Exclusion criteria

  • Presence of a concurrent active, incurable malignancy that may alter the outcome of the treatment for disease under treatment as determined by the treating physician.

  • Receiving any other investigational agents within 21 days or 5 half-lives (whichever is shorter) prior to the first dose of study drug.

  • Prior PD-1 or PD-L1 inhibitor therapy, or prior therapy with anti-PD-L2 or anti-CTLA-4 inhibitor, or any other drug specifically targeting T-cell co-stimulation or immune checkpoint pathways.

  • A history of allergic reactions attributed to compounds of similar chemical or biologic composition to vorolanib, nivolumab or pembrolizumab (as applicable), any monoclonal antibody, or other agents used in the study.

  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection.

  • Has a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration. Inhaled or topical steroids and adrenal replacement doses ≤ 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease. Patients are permitted to use topical, ocular, intra-articular, intranasal, and inhalational corticosteroids (with minimal systemic absorption). A brief course of corticosteroids for prophylaxis (e.g. contrast dye allergy) or for treatment of non-autoimmune conditions (e.g. delayed-type hypersensitivity reaction caused by contact allergens) is permitted.

  • Toxicities from prior therapy must have resolved to G1 or less prior to the first dose of study drug except those deemed not clinically significant per PI.

  • Active autoimmune disease or history of autoimmune disease that might recur, which may affect vital organ function or require immune suppressive treatment including systemic corticosteroids. This includes but is not limited to: history of immune-related neurologic disease, multiple sclerosis, autoimmune (demyelinating) neuropathy, Guillain-Barre syndrome, myasthenia gravis; systemic autoimmune disease such as SLE, connective tissue diseases, scleroderma, inflammatory bowel disease (IBD), Crohn's, ulcerative colitis, hepatitis; and a history of toxic epidermal necrolysis (TEN), Stevens-Johnson syndrome, or phospholipid syndrome. Patients with vitiligo or endocrine deficiencies including thyroiditis managed with replacement hormones including physiologic corticosteroids are eligible. Patients with rheumatoid arthritis and other arthropathies, Sjogren's syndrome, and psoriasis controlled with topical medication, and patients with positive serology, such as antinuclear antibodies (ANA) or anti-thyroid antibodies should be evaluated for the presence of target organ involvement and potential need for systemic treatment but should otherwise be eligible. Patients with type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, or conditions not expected to recur in the absence of an external trigger (precipitating event) are eligible.

  • Has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis.

  • History of clinically significant bleeding.

  • Patients who have had evidence of active or acute diverticulitis, intra-abdominal abscess, GI obstruction, and abdominal carcinomatosis which are known risk factors for bowel perforation should be evaluated for the potential need for additional treatment before coming on study.

  • Inability to swallow or retain oral medications or the presence of active GI disease or other conditions that will interfere significantly with the absorption, distribution, metabolism, or excretion of vorolanib.

  • Pregnant and/or breastfeeding. Women of childbearing potential must have a negative pregnancy test within 24 hours of study entry.

  • Active hepatitis B or hepatitis C. Note: no testing for hepatitis B or C is required unless mandated by local health authority.

  • Has a known history of active tuberculosis.

  • Known HIV-positivity.

  • Has received a live vaccine within 30 days prior to the first dose of study drug. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (e.g. FluMist) are live attenuated vaccines and are not allowed.

  • Major surgery within the last 4 weeks; minor surgery within the last 2 weeks.

  • Any radiotherapy within 3 weeks except palliative stereotactic body radiation therapy (SBRT) within 2 weeks.

  • Prior anti-cancer therapy given within 21 days or 5 half-lives (whichever is shorter)

  • Chemotherapy given on the weekly basis with limited potential for delayed toxicity within the last 2 weeks.

  • Symptomatic arterial peripheral vascular disease or significant cardiovascular disease or condition including:

    • Congestive heart failure (CHF) currently requiring therapy.
    • Class III or IV cardiovascular disease according to the New York Heart Association (NYHA) Functional Criteria.
    • Need for antiarrhythmic medical therapy for a ventricular arrhythmia.
    • Severe conduction disturbance (e.g. 3rd degree heart block).
    • Unstable angina pectoris (i.e. last episode ≤ 6 months prior to first dose of protocol-indicated treatment).

    • Myocardial infarction within 6 months prior to starting trial treatment.
    • QTcF >450 ms in men, or >470 ms in women.
