Olaparib in Treating Patients With Advanced Glioma, Cholangiocarcinoma, or Solid Tumors With IDH1 or IDH2 Mutations

NCT03212274

Description:

This phase II trial studies how well olaparib works in treating patients with glioma, cholangiocarcinoma, or solid tumors with IDH1 or IDH2 mutations that have spread to other places in the body and usually cannot be cured or controlled with treatment. Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Purpose

This phase II trial studies how well olaparib works in treating patients with glioma, cholangiocarcinoma, or solid tumors with IDH1 or IDH2 mutations that have spread to other places in the body and usually cannot be cured or controlled with treatment. Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed Description

      PRIMARY OBJECTIVES:

      I. To estimate the overall response rates of olaparib in subjects with recurrent/progressive
      IDH1/2-mutant solid tumors, who will be recruited to 3 cohorts: a. glioma, b.
      cholangiocarcinoma, c. other solid malignant tumors.

      SECONDARY OBJECTIVES:

      I. To estimate the distribution of progression free survival (PFS) of olaparib in adults with
      recurrent/progressive IDH1/2-mutant glioma and cholangiocarcinoma.

      II. To estimate the overall survival (OS) in adults with recurrent/progressive IDH1/2- mutant
      glioma and cholangiocarcinoma.

      III. To determine the duration of response in adults with recurrent/progressive IDH1/2-mutant
      glioma, cholangiocarcinoma or other solid malignant tumors.

      IV. To confirm the safety and tolerability of olaparib monotherapy.

      EXPLORATORY OBJECTIVES:

      I. To describe 2HG concentration in plasma by mass spectrometry at baseline and at specific
      timepoints and correlate with treatment response.

      II. To describe 2HG levels in tumor biopsies from prior to the beginning of treatment and at
      specific timepoints and correlate with treatment response.

      III. To evaluate in tumor biopsies and in liquid biopsies performed at baseline and at
      specific timepoints if co-occurring alterations detected via multiplexed immunofluorescence,
      mass cytometry (CyTOF)-imaging mass cytometry (IMC), ribonucleic acid (RNA) sequencing and/or
      deoxyribonucleic acid (DNA) sequencing can be associated with differential levels of 2HG
      production, treatment response and resistance.

      OUTLINE:

      Patients receive olaparib orally (PO) twice daily (BID) on days 1-28. Courses repeat every 28
      days in the absence of disease progression or unacceptable toxicity.

      After completion of study treatment, patients are followed up for 30 days.

Eligibility Criteria

        Inclusion Criteria:

          -  Subjects must be able to understand the nature of this trial and provide written
             informed consent, prior to any study specific procedures; patients with Impaired
             Decision Making Capacity (IDMC) who have a close caregiver or legally authorized
             representative (LAR) may be considered eligible for this study at the treating
             physician's discretion, provided that the physician is reasonably sure that the
             possible risks and benefits of the study are clear and that the patient will take the
             drug as prescribed

          -  Subjects must be diagnosed with a glioma, cholangiocarcinoma or other solid malignant
             tumor that has progressed despite standard therapy, or for which no effective standard
             therapy exists, with biopsy-confirmed evidence of an IDH1 or IDH2 mutation associated
             with neomorphic activity of the encoded proteins; patients must have IDH1 or IDH2
             mutation which must be detected in a clinical accredited laboratory using a Food and
             Drug Administration (FDA)-approved molecular test or a validated deoxyribonucleic acid
             (DNA)-based assay conducted in a Clinical Laboratory Improvement Amendments
             (CLIA)-certified laboratory; only specific mutations that lead to a neomorphic
             phenotype will be eligible for enrollment, and include IDH1: R132V, R132G, R132S,
             R132L, R132C and R132H; IDH2: R140W, R140L, R140Q, R172W, R172G, R172S, R172M, R172K

          -  Patients must have tumors determined to be easily accessible for biopsy and must be
             willing to have serial biopsies (with a third biopsy upon evidence of disease
             progression); in case of multiple lesions, tumor biopsies will be performed on the
             most accessible site of disease; all possible precautions to avoid complications will
             be taken, including discussions in multidisciplinary meetings, if needed; patients
             affected by glioma will not be considered for study biopsies

          -  Patients must be willing to undergo extra blood sampling for correlative studies

          -  Subjects with extracranial disease must have evaluable disease by Response Evaluation
             Criteria in Solid Tumors version 1.1 (RECIST v1.1); subjects affected by glioma must
             have evaluable disease by Response Assessment in Neuro-Oncology Criteria (RANO)
             criteria

          -  For subjects with glioma, specific inclusion criteria are as follows:

               -  The disease should be recurrent or transformed glioma; subjects must not have had
                  prior surgery (biopsy allowed) or radiation therapy within 3 weeks of enrollment

               -  There must be an enhancing component of disease, as evaluated on pre-treatment
                  magnetic resonance imaging (MRI)

               -  For patients with World Health Organization (WHO) grade III or IV glioma and
                  progressive disease < 12 weeks after completion of chemoradiotherapy, progression
                  can be defined by the following set of criteria:

                    -  New enhancement outside of the radiation field (beyond the high-dose region
                       or 80% isodose line)

                    -  If there is unequivocal evidence of viable tumor on histopathologic sampling
                       (e.g., solid tumor areas. i.e., > 70% tumor cell nuclei in areas), high or
                       progressive increase in MIB-1 proliferation index compared with prior
                       biopsy, or evidence for histologic progression or increased anaplasia in
                       tumor);

                    -  Note: Given the difficulty of differentiating true progression from
                       pseudoprogression, clinical decline alone, in the absence of radiographic or
                       histologic confirmation of progression, will not be sufficient for
                       definition of progressive disease in the first 12 weeks after completion of
                       concurrent chemoradiotherapy

               -  For patients with WHO grade III or IV glioma and progressive disease >= 12 weeks
                  after completion of chemoradiotherapy, progression can be defined by the
                  following set of criteria:

                    -  New contrast-enhancing lesion outside of radiation field on decreasing,
                       stable, or increasing doses of corticosteroids

                    -  Increase by >= 25% in the sum of the products of perpendicular diameters
                       between the first post-radiotherapy scan, or a subsequent scan with smaller
                       tumor size, and the scan at 12 weeks or later on stable or increasing doses
                       of corticosteroids

                    -  For patients receiving antiangiogenic therapy, significant increase in
                       T2/fluid attenuated inversion recovery (FLAIR) non-enhancing lesion may also
                       be considered progressive disease; the increased T2/FLAIR must have occurred
                       with the patient on stable or increasing doses of corticosteroids compared
                       with baseline scan or best response after initiation of therapy and not be a
                       result of comorbid events (e.g., effects of radiation therapy,
                       demyelination, ischemic injury, infection, seizures, postoperative changes,
                       or other treatment effects)

                    -  Note: Clinical deterioration alone is not attributable to concurrent
                       medication or comorbid conditions is sufficient to declare progression on
                       current treatment but not for entry onto a clinical trial for recurrence

               -  For patients with WHO grade II glioma progression is defined by any one of the
                  following:

                    -  Development of new lesions or increase of enhancement (radiological evidence
                       of malignant transformation)

                    -  A 25% increase of the T2 or FLAIR non-enhancing lesion on stable or
                       increasing doses of corticosteroids compared with baseline scan or best
                       response after initiation of therapy, not attributable to radiation effect
