Study Description

Brief Summary

This phase II trial studies how well olaparib and ceralasertib (AZD6738) work in treating patients with IDH mutant cholangiocarcinoma or solid tumors. Cancer is caused by changes (mutations) to genes that control the way cells function. Laboratory studies have shown that olaparib and AZD6738 can shrink IDH mutant tumors or stop them from growing. Olaparib and ceralasertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed Description

PRIMARY OBJECTIVE:
  1. To determine the overall response rates of olaparib and ceralasertib (AZD6738) in subjects with recurrent/progressive IDH1/2-mutant solid malignant tumors, who will be recruited to 2 cohorts: a. Cholangiocarcinoma b. Other solid malignant tumors.
SECONDARY OBJECTIVES:
  1. To assess the progression free survival (PFS) of olaparib and AZD6738 in adults with recurrent/progressive IDH1/2-mutant solid malignant tumors.

  2. To estimate the overall survival (OS) in adults with recurrent/progressive IDH1/2- mutant solid malignant tumors.

  3. To assess the duration of response in adults with recurrent/progressive IDH1/2-mutant solid malignant tumors.

  4. To assess the safety and tolerability of the combination of olaparib and AZD6738.

EXPLORATORY OBJECTIVES:
  1. To evaluate 2-hydroxyglutarate (2HG) concentration in plasma by mass spectrometry and correlate with treatment response.

  2. To evaluate 2HG levels in tumor biopsies prior to the beginning of treatment and while on therapy and correlate with treatment response.

  3. Correlate 2HG concentration in plasma and in tumor biopsies. IV. To evaluate deoxyribonucleic acid (DNA) double strand breaks (DSBs) as measured by mass cytometry time of flight (CyTOF)-imaging mass cytometry (IMC) in tumor biopsies before and after treatment with olaparib and AZD6738.

OUTLINE:

Patients receive olaparib orally (PO) twice daily (BID) on days 1-28 and ceralasertib PO once daily (QD) on days 1-7. Cycles 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.

  • Outcome Measures

    Primary Outcome Measures

    1. Objective response rate (ORR) [Up to 30 days post treatment after removal from study]

      The exact two-sided 95% confidence intervals (CIs) for the ORR will be reported.

    Secondary Outcome Measures

    1. Progression free survival (PFS) [From start of treatment to time of progression or death, whichever occurs first, assessed up to 30 days after removal from study]

      PFS will be estimated using the Kaplan-Meier method with the 95% CIs. The CI based on the Greenwoods variance will be reported. In addition, the possible risk factors will be compared for survival with log-rank test. For multivariate analysis, the proportional hazards Cox model will be applied to investigate potential prognostic factors, such as age and stage of disease on the survival data. The adjusted p-values of the odds ratios and the adjusted 95% confidence interval will be reported.

    2. Overall survival (OS) [From start of treatment to time of death, assessed up to 30 days after removal from study]

      OS will be estimated using the Kaplan-Meier method with the 95% CIs. The CI based on the Greenwoods variance will be reported. In addition, the possible risk factors will be compared for survival with log-rank test. For multivariate analysis, the proportional hazards Cox model will be applied to investigate potential prognostic factors, such as age and stage of disease on the survival data. The adjusted p-values of the odds ratios and the adjusted 95% confidence interval will be reported.

    3. Duration of response [From the time measurement criteria are met for complete response or partial response (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented, assessed up to 30 days after removal from study]

      Will be estimated using the Kaplan-Meier method with the 95% CIs. The CI based on the Greenwoods variance will be reported. In addition, the possible risk factors will be compared for survival with log-rank test. For multivariate analysis, the proportional hazards Cox model will be applied to investigate potential prognostic factors, such as age and stage of disease on the survival data. The adjusted p-values of the odds ratios and the adjusted 95% confidence interval will be reported.

    4. Incidence of adverse events [Up to 30 days post treatment]

      Toxicities will be evaluated utilizing the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0.

    Other Outcome Measures

    1. Absolute and fold changes in gamma H2AX foci [Baseline up to 30 days post treatment]

      Absolute and fold changes for gamma H2AX foci will be calculated between baseline and subsequent follow-up (pre-treatment and on-treatment biopsies). These will be displayed graphically versus (vs). time for each cohort. Differences will be plotted vs. response status. Wilcoxon sign-rank test as well as paired t-tests will be used to evaluate if differences between baseline and each subsequent time point are significant. Summary statistics will be reported (with 95% confidence intervals) to demonstrate mean differences in fold-change (or log fold-change) between responders and non-responders.

    2. 2HG levels [Up to 30 days post treatment]

      2HG levels in tumor and plasma will be compared to treatment responses. The Mann-Whitney U test will be used to test for differences in post-treatment tissue and plasma 2HG concentrations between patients with a response to treatment and those without. Will also apply analysis of covariance for post-treatment plasma concentration in 2HG adjusted for the pre-treatment plasma concentration between patients with a response to treatment and those without.

    Eligibility Criteria

    Criteria

    Ages Eligible for Study:
    18 Years and Older
    Sexes Eligible for Study:
    All
    Accepts Healthy Volunteers:
    No
    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 cholangiocarcinoma or other solid malignant tumor that has progressed despite standard therapy, or for which no effective standard therapy exists. Patients with primary central nervous system (CNS) tumors, e.g. glioma, are not allowed

    • Patients must have biopsy-confirmed evidence of an IDH1 or IDH2 mutation, confirmed in a Clinical Laboratory Improvement Act (CLIA)-certified laboratory, associated with neomorphic activity of the encoded proteins

    • Patients must have tumors determined to be easily accessible for biopsy and must be willing to have serial biopsies. Tumor biopsies will be performed on the most accessible biopsiable site of disease. All possible precautions to avoid complications will be taken, including discussions in multidisciplinary meetings, if needed. If a patient opts out of a pre-treatment biopsy, biopsy is not possible, or if a pre-treatment biopsy does not yield sufficient tissue for analysis, the patient must be willing to provide an archival formalin-fixed paraffin-embedded (FFPE) specimen, if available, for liquid chromatography/mass spectrometry (LC/MS) analysis of 2HG. Permission of the study principal investigator (PI) is required in all of the above scenarios

    • In order to maximize the availability of newly obtained specimens for 2-HG analysis, at least 10 biopsies will be required in each group (cholangiocarcinoma and other solid tumors) of 14 patients treated in the first stage of this Simon two-stage design. Thus if 4 patients in an arm have already opted out, further patients may only enroll on that arm (in the first stage) if they agree to undergo the pre- and on-treatment biopsies. If a patient has agreed to undergo the two biopsies and undergoes the pre-treatment biopsy, he or she may not opt out of the second biopsy unless such a biopsy would not be safe (e.g. inaccessible tumor). Permission of the study PI is required in this scenario

    • All patients must be willing to provide 5 unstained archival slides, if available, for pre-treatment 2-HG analysis and correlation with 2-HG levels in pre-treatment frozen specimens

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

    • Patients must have measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1

    • Patients must have at least one lesion, not previously irradiated, that can be accurately measured at baseline as >= 10 mm in the longest diameter (except lymph nodes which must have short axis >= 15 mm) with computed tomography (CT) or magnetic resonance imaging (MRI) or >= 10 mm with callipers by clinical exam OR at least one lesion (measurable and/or non-measurable) that can be accurately assessed by CT/MRI/clinical exam at baseline and follow up visits

    • Subjects must have progressive cancer at the time of study entry

    • Prior experimental (non-Food and Drug Administration [FDA] approved) therapies (other than drugs that target ATR) and immunotherapies are allowed. Patients must not have received these therapies for 30 days or five half lives of the drug (whichever is less) prior to the initiation of study treatment
