Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Age ≥ 18 years.
  • Have histologically confirmed chordoma that is not dedifferentiated or poorly differentiated subtype.

    • Hemoglobin > 9 g/dL
    • Serum electrolytes (sodium, potassium, magnesium, phosphorus, calcium) Grade ≤1 or within the institutional ranges of normal. If clinically appropriate, electrolytes may be corrected, and values reassessed prior to enrollment.
    • AST and ALT ≤ 2.5 × ULN or ≤ 5 × ULN for patients with liver metastases
    • Total bilirubin ≤ 1.5 × ULN (except in patients with Gilbert Syndrome who can have total bilirubin < 3.0 mg/dL)
    • Serum creatinine clearance <1.5 times ULN or ≥ 50 mL/min as determined by Cockcroft-Gault (Appendix 7) (creatinine clearance need not be calculated if serum creatinine is within normal limits).

Female patients of childbearing potential must have a negative serum beta-human chorionic gonadotropin pregnancy test within 7 days prior to receiving the first dose of study medication.

  • Female patients of childbearing potential must be willing to use an adequate method of contraception, as outlined in the protocol, for the course of the study through 120 days after last dose of study medication.
  • Male patients of childbearing potential must agree to use an adequate method of contraception, as outlined in the protocol, starting with the first dose of study therapy through 120 days after the last dose of study therapy.
  • Willing to comply with all protocol required- visits, assessments, and procedures.

  • Non-English speaking patients will not be required to complete patient reported outcomes.

Exclusion Criteria:

  • Previous treatment with a SHP2 inhibitor.
  • Documented PTPN11 mutations.
