ivosidenib and nivolumabConcurrent dosing of ivosidenib and nivolumab


In this study, response to treatment and (progression free and overall) survival will be described and safety events of ivosidenib in combination with nivolumab will be summarized in patients with advanced solid tumors (nonresectable or metastatic) or enhancing gliomas.

Detailed Description

      This study will describe the safety, response rate, progression free and overall survival,
      and summarize safety events of ivosidenib in combination with nivolumab in participants with
      advanced solid tumors (nonresectable or metastatic) or enhancing gliomas. Participants are
      required to have a histologically consistent diagnosis of IDH1 gene mutated tumor that is not
      eligible for curative therapy. Enrolled subjects will receive orally administered ivosidenib
      dosed daily on 28-day cycles and nivolumab will be infused every 28 days. Participants will
      be assessed at every visit for adverse events starting from the first dose of study
      treatment. Assessment (CT or MRI) for evaluation of disease response will be conducted every
      8 weeks (±7 days) from the first day of treatment cycle 1 and/or at any time when progression
      of disease is suspected. A Post-Treatment Follow-Up Visit for safety will occur 28 (+/- 5)
      days after the last dose of study drug.

Trial Arms

Concurrent dosing of ivosidenib and nivolumabExperimentalIvosidenib will be administered concurrently with nivolumab on a Q28 day schedule.

             investigational product administration or may interfere with the interpretation of
             study results and, in the judgment of the treating investigator, would make the
             participant inappropriate for entry into this study.

          -  Have known active inflammatory gastrointestinal disease, chronic diarrhea, previous
             gastric resection or lap band dysphagia, short-gut syndrome, gastroparesis, or other

Primary Outcome Measures

Measure:Occurrence of dose limiting toxicity (DLT)
Time Frame:Up to 24 months
Safety Issue:
Description:The occurrence (number) of dose limiting toxicity (DLT) in patients receiving ivosidenib plus nivolumab. DLT describes side effects of the treatment that are serious enough to prevent an increase in dose or level of that treatment.

Secondary Outcome Measures

Measure:Adverse Events Related to Treatment
Time Frame:Up to 24 months
Safety Issue:
Description:Adverse events per NCI Common Terminology Criteria for Adverse Events (CTCAE v5.0), experienced by patients related to their receiving the treatment combination of ivosidenib and nivolumab.
Measure:Overall Survival (OS)
Time Frame:Up to 36 months
Safety Issue:
Description:The length of time from the start of treatment that patients diagnosed with the disease are still alive.
Measure:Objective Tumor Progression
Time Frame:Up to 24 months
Safety Issue:
Description:Solid Tumor-Progression per RECIST v1.1 Criteria:Progressive Disease (PD):≥20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). The sum must also demonstrate an absolute increase of ≥5 mm. The appearance ≥1 new lesion(s) is considered progression. Glioma-Tumor progression per RANO Criteria: Progressive Disease: No CR, PR, SD prior to PD. Progression: 25% or more increase in enhancing lesions despite stable or increasing steroid dose, increase (significant) in non-enhancing FLAIR/T2W lesions, not attributable to other non-tumor causes, any new lesions; clinical deterioration (not attributable to other non-tumor causes and not due to steroid decrease)
