Details and patient eligibility


This trial is an open-label, multicenter, Phase 0 trial that will enroll up to 20 participants with recurrent high-grade glioma with FGFR1 K656E or FGFR3 K650E mutation or FGFR3-TACC3 translocation which are scheduled for resection. In the lead-in cohort, a total of 20 participants will be enrolled into the proposed phase 0 clinical trial. Participants will be administered infigratinib prior to surgical resection of their tumor.

  6. Ability to understand and the willingness to sign a written informed consent document (personally or by the legally authorized representative, if applicable).

  7. Has voluntarily agreed to participate by giving written informed consent (personally or via legally authorized representative(s), and assent if applicable). Written informed consent for the protocol must be obtained prior to any screening procedures. If consent cannot be expressed in writing, it must be formally documented and witnessed, ideally via an independent trusted witness.

  8. Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests and other procedures.

  9. Age ≥18 at time of consent

  10. Have a performance status (PS) of ≤2 on the Eastern Cooperative Oncology (Group (ECOG) scale (Oken et al. 1982)

  11. Ability to swallow oral medications.

  12. Has adequate bone marrow and organ function as defined by the following laboratory values (as assessed by the local laboratory for eligibility):

    1. Adequate bone marrow function:

      • absolute neutrophil count ≥1,000/mcL
      • Platelets (at time of surgery) ≥100,000/mcL
      • hemoglobin ≥8.0 g/dL Participants may receive erythrocyte transfusions to achieve this hemoglobin level at the discretion of the investigator.
    2. Adequate hepatic and renal function:

      • total bilirubin ≤1.5 X ULN Participants with Gilbert's syndrome with a total bilirubin ≤2.0 times ULN and direct bilirubin within normal limits are permitted.
      • AST(SGOT) ≤3 X institutional ULN
      • ALT(SGPT) ≤3 X institutional ULN
      • Calculated or measured creatinine clearance ≥45 mL/min
    3. Other Lab Values:

      • Amylase or lipase ≤2 X institutional ULN
      • calcium or phosphorus, or calcium-phosphorus product <55 mg2/dL2
    <!-- -->
    1. Inorganic phosphorus within normal limits
    2. Total corrected serum calcium within normal limits
  13. Confirmed negative serum pregnancy test (β-hCG) before starting study treatment or participant has had a hysterectomy.

  14. For females of reproductive potential: use of highly effective contraception for at least 1 month prior to screening and agreement to use such a method during study participation and for an additional 3 months after the end of treatment administration.

  15. For males of reproductive potential: use of condoms or other methods to ensure effective contraception with partner and for an additional 1 month after the end of treatment administration. A condom is required to be used also by vasectomized men as well as during intercourse with a male partner to prevent delivery of the drug via seminal fluid.

  16. Agreement to adhere to Lifestyle Considerations throughout study duration.

  17. Participants who received chemotherapy must have recovered (Common Terminology Criteria for Adverse Events [CTCAE] Grade ≤1) from the acute effects of chemotherapy except for residual alopecia or Grade 2 peripheral neuropathy prior to Day 1. A washout period of at least 21 days is required between last chemotherapy dose and Day 1 (provided the patient did not receive radiotherapy).

  18. Participants who received radiotherapy must have completed and fully recovered from the acute effects of radiotherapy. A washout period of at least 14 days is required between end of radiotherapy and Day 1.

Exclusion criteria

  1. Have a history of liver transplant.

  2. Have impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of oral infigratinib (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, small bowel resection).

  3. Known active systemic bacterial infection (requiring intravenous [IV] antibiotics at time of initiating study treatment), fungal infection, or detectable viral infection (such as known human immunodeficiency virus positivity or with known active hepatitis B or C [for example, hepatitis B surface antigen positive]. Screening is not required for enrollment.

  4. Have a history and/or current evidence of extensive tissue calcification including, but not limited to, the soft tissue, kidneys, intestine, myocardium, vascular system, and lung with the exception of calcified lymph nodes, minor pulmonary parenchymal calcifications, and asymptomatic coronary calcification.

  5. Have current evidence of corneal or retinal disorder/keratopathy including, but not limited to, bullous/band keratopathy, inflammation or ulceration, keratoconjunctivitis confirmed by ophthalmic examination. Subjects with asymptomatic ophthalmic conditions assessed by the investigator to pose minimal risk for study participation may be enrolled in the study.

  6. Have current evidence of endocrine alterations of calcium/phosphate homeostasis, e.g., parathyroid disorders, history of parathyroidectomy, tumor lysis, tumoral calcinosis etc.

  7. Have had a recent (≤3 months prior to first dose of study drug) transient ischemic attack or stroke.

  8. CTCAE (v5.0) Grade ≥2 hearing loss.

    4. QTcF >470 msec (males and females). Note: If the QTcF is >470 msec in the first ECG, a total of 3 ECGs separated by at least 5 minutes should be performed. If the average of these 3 consecutive results for QTcF is ≤470 msec, the participant meets eligibility in this regard.
    5. Known history of congenital long QT syndrome.
  11. Has serious and/or uncontrolled preexisting medical condition(s) that, in the judgment of the investigator, would preclude participation in this study (for example, interstitial lung disease, severe dyspnea at rest or requiring oxygen therapy, severe renal impairment [e.g. estimated creatinine clearance <30ml/min], history of major surgical resection involving the stomach or small bowel, or preexisting Crohn's disease or ulcerative colitis or a preexisting chronic condition resulting in baseline Grade 2 or higher diarrhea).

  12. Prior therapy with any mitogen-activated protein kinase (MEK) or FGFR inhibitor. Prior therapy is defined as a therapeutic dosing, as determined by the Investigator.

  13. Are currently receiving or are planning to receive during participation in this study, treatment with agents that are known strong inducers or inhibitors of CYP3A4 and medications which increase serum phosphorus and/or calcium concentration.
