Clinical Trial Summary

This phase I trial studies the side effects and best dose of olaparib and onalespib when given together in treating patients with solid tumors that have spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable) or ovarian, fallopian tube, primary peritoneal, or triple-negative breast cancer that has come back (recurrent). Olaparib and onalespib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Description:

PRIMARY OBJECTIVE: I. To establish the maximum tolerated dose (MTDs) of olaparib and onalespib (AT13387) administered in combination in patients with advanced solid tumors. SECONDARY OBJECTIVES: I. To identify the dose-limiting toxicity (DLT) and other toxicities associated with olaparib and AT13387 administered in combination as assessed by Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0. II. To determine the recommended phase 2 doses (RP2D) of the combination of olaparib and AT13387. III. To determine the plasma pharmacokinetics of olaparib and AT13387. IV. To document anti-tumor activity of the combination of olaparib and AT13387 as assessed by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and progression free survival (PFS). Although the clinical benefit of [this/these] drug(s) has not yet been established, the intent of offering this treatment is to provide a possible therapeutic benefit, and thus the patient will be carefully monitored for tumor response and symptom relief in addition to safety and tolerability. OUTLINE: This is a dose-escalation study. Patients receive olaparib orally (PO) twice daily (BID) on days 1-7 (cycle 0). Beginning in cycle 1, patients receive olaparib PO BID on days 1-28 and onalespib intravenously (IV) over 1 hour on days 1, 2, 8, 9, 15, and 16. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 30 days and every 3 months for up to 2 years.

• Triple-negative breast cancer (TNBC) which has recurred despite standard therapy; recurrent TNBC needs to have metastatic disease and patients with an in breast recurrence are not eligible; up to 4 prior lines in the recurrent setting for patients with triple-negative breast cancer are allowed
• For the dose expansion cohort, patients with ovarian, fallopian tube or primary peritoneal cancer must have platinum resistant disease defined as progression within 6 months after last platinum regimen; platinum refractory disease is allowed
• For the dose expansion cohort, patients with triple-negative breast cancer may not be BRCA1/2 germline mutation carriers
• Because no dosing or adverse event data are currently available on the use of olaparib in combination with AT13387 in patients < 18 years of age, children are excluded from this study, but will be eligible for future pediatric trials.

• Any clinically significant electrolyte imbalance, particularly hypokalemia and hypomagnesemia, should be corrected before treatment
• Pre-study evaluation must include an ophthalmologic exam by an ophthalmologist (not optometrist) and should minimally include visual acuity testing, slit lamp examination, and funduscopic examination; follow up eye-exams will only be performed if subjects develop/report any visual impairment; visual impairment may include peripheral flashes (photopsia), blurred or double vision, floaters, color distortion and dimness, difficulties with light/dark accommodation, tunnel vision or other field defects, halos, apparent movement of stationary objects, and complex disturbances; follow up eye-exams will minimally include visual acuity testing, slit lamp examination, and funduscopic examination; additional testing will be based on symptoms, what is observed and ophthalmologist recommendations
• For the expansion cohort only: measurable disease by RECIST v1.1 with at least one measurable target lesion
• The effects of olaparib in combination with AT13387on the developing human fetus are unknown; for this reason and because olaparib and AT13387 are anti-neoplastic small molecule inhibitors, which are agents that are potentially teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 3 months after the last dose of study drugs; should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately; men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of olaparib and/or AT13387 administration
• Patients must be able to swallow tablets and have no significant impairment in gastrointestinal absorption
• Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

• Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
• All acute, clinically significant treatment-related toxicity from prior therapy, except for alopecia, must have resolved to grade =< 1
• Patients who are receiving any other investigational agents
• Patients with known active or history of brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to olaparib and AT13387 used in study
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
• Pregnant women are excluded from this study because olaparib and AT13387 are agents with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with AT13387 or olaparib, breastfeeding should be discontinued if the mother is treated with olaparib or AT13387
• Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with olaparib or AT13387; in addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy; appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated
• Known history of QT/corrected QT (QTc) prolongation or torsades de pointes (TdP); patients who are currently receiving treatment with medication with a known risk to prolong the QT interval or inducing torsades de pointes and the treatment cannot either be discontinued or switched to a different medication prior to starting study drugs
• Participants receiving any medications or substances that are strong inhibitors or inducers of CYP3A4 or moderate inhibitors of CYP3A4 are ineligible; the study team should check a frequently-updated medical reference for a list of drugs to avoid or minimize use of; as part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
• Participants with myelodysplastic syndrome/acute myeloid leukemia or with features suggestive of myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maximum Tolerated Dose (MTD) of Olaparib Administered in Combination With Onalespib	MTD was determined by testing increasing doses of the combination of olaparib PO and onalespib IV within dose escalation cohorts consisting of 3 to 6 evaluable participants. MTD reflects the highest dose combination that did not cause a Dose-Limiting Toxicity (DLT) in > 33% of participants. DLTs were defined based on the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0.; Enrollment to this study was suspended prior to completion of the dose escalation due to discontinuation of further development of onalespib. A true single MTD therefore could not be determined. The two dose levels included in this outcome measure represent the highest well-tolerated dose combinations (Dose Level 2 [DL2]: Olaparib 300 mg PO BID and Onalespib 40 mg/m^2 IV; and Dose Level 2a [DL2a]: Olaparib 200 mg PO BID and Onalespib 80 mg/m^2 IV).	Up to 35 days for each dose level cohort
Primary	Maximum Tolerated Dose (MTD) of Onalespib Administered in Combination With Olaparib	MTD was determined by testing increasing doses of the combination of olaparib PO and onalespib IV within dose escalation cohorts consisting of 3 to 6 evaluable participants. MTD reflects the highest dose combination that did not cause a Dose-Limiting Toxicity (DLT) in > 33% of participants. DLTs were defined based on the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0.	Up to 35 days for each dose level cohort
Secondary	Number of Participants Who Experienced Dose-Limiting Toxicities (DLTs)	DLTs were based on the NCI Common Terminology Criteria for Adverse Events (CTCAE) v.5.0 and were defined as any grade 3 or 4 non-hematologic toxicity (excluding grade 3: fatigue; diarrhea, constipation, and nausea and/or vomiting controlled with supportive measured within 24 hours; hypophosphatemia; hyponatremia; hypomagnesemia; and rash that resolves to < grade 3 within < 5 days), grade 4 neutropenia of > 7 day duration, febrile neutropenia, grade 4 thrombocytopenia or bleeding associated with grade 3 thrombocytopenia, requirement for repeated blood transfusion within 4-6 weeks, any other grade 4 hematologic toxicity, any study treatment-related death, any grade 3 or 4 event considered to be dose-limiting in the opinion of the investigator, and the inability to take 75% or more of the planned dose for olaparib and 4 out of 6 doses for onalespib within the DLT period due to treatment-related adverse events.	Within Cycles 0 and 1 (up to 35 days).
Secondary	Number of Participants Who Experienced Treatment-Related Toxicities	Treatment-related toxicities in this outcome include non-hematologic and hematologic adverse events that were either Grade 3+ or occurred in at least 10% of all treated participants, and were considered at least possibly related to olaparib and/or onalespib. Adverse events were graded according to the NCI Common Terminology Criteria for Adverse Events (CTCAE) v.5.0.	Up to 67 weeks
Secondary	Number of Participants With Objective Responses by RECIST 1.1	Responses determined per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by CT or MRI, where Objective Response (OR) represents either a Complete Response (CR; disappearance of all target lesions) or a Partial Response (PR; at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum diameters).	Up to 63 weeks
Secondary	Number of Participants Progression-Free for At Least 24 Weeks by RECIST 1.1	Responses determined per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by CT or MRI, where Progressive Disease (PD) represents (relative to baseline) at least a 20% increase in the sum of diameters of target lesions, appearance of one or more new lesions, or unequivocal progression of existing non-target lesions. The duration of progression-free status was defined as the interval from the date of enrollment to date of either PD or date of last disease assessment.	Up to 24 weeks
