Study of AG-120 in Previously Treated Advanced Cholangiocarcinoma With IDH1 Mutations (ClarIDHy)

Overview

  • Study type

    Interventional
  • Study phase

    III
  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

Study AG120-C-005 is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study of orally administered AG-120. Subjects, all personnel involved in the evaluation of subjects' response to treatment (e.g., Investigators, study coordinators, study pharmacists), and designated Sponsor team members will be blinded to study treatment. Subjects are required to have a histologically-confirmed diagnosis of IDH1 gene-mutated cholangiocarcinoma that is not eligible for curative resection, transplantation, or ablative therapies prior to enrollment.IDH1 mutation testing will be performed at participating investigative sites. Subjects must have progression of disease and have received at least 1 but not more than 2 prior treatment regimens for advanced disease (nonresectable or metastatic). All subjects must have received either a gemcitabine or a 5 fluorouracil (5-FU) based chemotherapy regimen.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

See eligibility criteria

Inclusion Criteria:

  1. Be ≥18 years of age.
  2. Have a histopathological diagnosis (fresh or banked tumor biopsy sample, preferably collected within the last 3 years) of nonresectable or metastatic cholangiocarcinoma and are not eligible for curative resection, transplantation, or ablative therapies.
  3. Have documented IDH1 gene-mutated disease (from a fresh tumor biopsy or the most recent banked tumor tissue available) based on central laboratory testing (R132C/L/G/H/S mutation variants tested).
  4. Have an ECOG PS score of 0 or 1
  5. Have an expected survival of ≥3 months.
  6. Have at least one evaluable and measurable lesion as defined by RECIST v1.1. Subjects who have received prior local therapy (including but not limited to embolization, chemoembolization, radiofrequency ablation, or radiation therapy) are eligible provided measurable disease falls outside of the treatment field or within the field and has shown ≥20% growth in size since post-treatment assessment.
  7. Have documented disease progression following at least 1 and no more than 2 prior systemic regimens for advanced disease (nonresectable or metastatic). Subjects must have received at least 1 gemcitabine- or 5-FU-containing regimen for advanced cholangiocarcinoma. Subjects who have received systemic adjuvant chemotherapy will be permitted provided there is documented disease progression during or within 6 months of completing the therapy.

Exclusion Criteria:

  1. Received a prior IDH inhibitor.
  2. Received systemic anticancer therapy or an investigational agent <2 weeks prior to Day 1 (washout from prior immune based anticancer therapy is 4 weeks). In addition, the first dose of study treatment should not occur before a period ≥5 half-lives of the investigational agent has elapsed.
  3. Received radiotherapy to metastatic sites of disease <2 weeks prior to Day 1.
  4. Underwent hepatic radiation, chemoembolization, and radiofrequency ablation <4 weeks prior to Day 1.
  5. Have known symptomatic brain metastases requiring steroids. Subjects with previously diagnosed brain metastases are eligible if they have completed their treatment and have recovered from the acute effects of radiation therapy or surgery prior to study entry, have discontinued corticosteroid treatment for these metastases for at least 4 weeks and have radiographically stable disease for at least 3 months prior to study entry. Note: up to 10 mg per day of prednisone equivalent will be allowed.
