Ovarian Cancer Clinical Trial

IACS-6274 With or Without Pembrolizumab for the Treatment of Advanced Solid Tumors

Summary

This phase I trial tests the safety, side effects, and best dose of IACS-6274 with or without pembrolizumab in treating patients with solid tumors that have spread to other places in the body (advanced). IACS-6274 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving IACS-6274 with or without pembrolizumab may help to control the disease.

Primary Objectives:

To assess the safety and tolerability of oral IACS-6274 as monotherapy (Part A) and in combination with bevacizumab and weekly paclitaxel (Part B).

For Dose Escalation Only:

• To determine the maximum tolerated dose (MTD) and the recommended phase 2 dose (RP2D) of IACS-6274 and in combination with bevacizumab and weekly paclitaxel (Part B).

Secondary Objectives:

To assess the preliminary antitumor activity of IACS-6274 as monotherapy (Part A) and in combination with bevacizumab and weekly paclitaxel (Part B) in patients with or without biomarker selected tumor types.
To characterize the PK profile of IACS-6274 as a monotherapy (Part A) and in combination with bevacizumab and weekly paclitaxel (Part B).
To evaluate predictive biomarkers of response and correlate with clinical outcome.

Exploratory Objectives:

• To collect biobank samples for potential future analysis of biomarkers (optional, informed consent required).

OUTLINE: This is a dose-escalation study of IACS-6274 followed by a dose-expansion study. Patients are assigned to 1 of 2 parts.

PART A: Patients receive IACS-6274 orally (PO) twice daily (BID) on days 1-21. Cycles repeat every 21 days for 2 years in the absence of disease progression or unacceptable toxicity.

PART B: Patients receive IACS-6274 PO BID on days 1-21 and bevacizumab and paclitaxel intravenously (IV). Cycles repeat every 21 days for 2 years in the absence of disease progression or unacceptable toxicity.

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

Eligibility Criteria

Inclusion Criteria:

Provision of written informed consent prior to any study related procedures and compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
Male or female patients ≥18 years of age at the time of study entry who agree to participate by giving written informed consent prior to participation in any study related activities.

Histologically or cytologically confirmed advanced solid tumors, specifically:

Dose Escalation for Part A may include:

Patients with tumors harboring actionable KEAP1/NFE2L2/STK11/NF1 mutations
Patients with low ASNS expression levels (HGSOC or endometrial cancer)
Patients who had immunotherapy (IO) melanoma (Minimum treatment duration of prior PD-1 or PD-L1-containing regimen of 12 weeks [or equivalent of 2 response evaluations]).
Patients with post-platinum HNSCC
Patients with chondrosarcoma
Patients with ARID1A mutant clear cell ovarian cancer

Dose Escalation for Part B may include:

- Confirmed recurrent high-grade non-mucinous ovarian cancer that is platinum-resistant, defined as disease relapse within a platinum-free interval (PFI, or the time elapsed from the last date of platinum dose until PD) of < 6 months

Dose Expansion for Part B will be limited to:

- Confirmed recurrent high-grade non-mucinous ovarian cancer with low ASNS expression levels that is platinum-resistant, defined as disease relapse within a PFI of < 6 months, and with less than 5 prior therapies.

Note: all biomarker mutations/expression levels must be confirmed prior to study treatment.

Patients must have received at least one line of therapy for advanced stage disease and be refractory or ineligible to available existing therapy(ies) known to provide clinical benefit for their condition.
Prior treatment with chemotherapy, radiotherapy, immunotherapy or any investigational therapies must have been completed at least 3 weeks or at least five half lives, whichever is shorter, before the study drug administration, and all AEs (excluding alopecia and peripheral neuropathy) have either returned to ≤Grade 1 or stabilized.
Fresh and/or archival tumor tissue from a biopsy obtained between the completion of the most recent line of treatment until study entry must be available for mutation and biomarker analysis. If available, archival tumor tissue from the time of initial diagnosis or the most recent biopsy (archival and/or fresh) will be collected. For ovarian cancer patients, a fresh biopsy must be collected in addition to archival tumor tissue. NOTE: No fresh tumor tissue will be required if a previous biopsy detected the selected mutations for each cohort. In all cases, procedures to obtain fresh tumor tissue should not put the patient at undue risk, and should only be performed if the risk is minimal (no greater than 2% risk of serious or severe complications).
Patients must have at least 1 lesion (measurable and/or non-measurable) that can be accurately assessed at baseline by CT or MRI and is suitable for repeated assessments.

Platelets ≥1.0×109/L
Hemoglobin ≥9.0 g/dL (>5.59 mmol/L)
Creatinine clearance (CrCl) >50 mL/min. Actual body weight should be used for calculating creatinine clearance using the Cockroft Gault equation (except for patients with body mass index >30 kg/m2 when the lean body weight should be used, and without the need for chronic dialysis therapy).
Serum total bilirubin ≤1.5×ULN (with the exception of patients with known Gilbert's syndrome: serum total bilirubin must be <3×ULN in these patients)
Aspartate aminotransferase (serum glutamic oxaloacetic transaminase) and alanine aminotransferase (serum glutamic pyruvic transaminase) ≤2.5×ULN or ≤5×ULN for patients with liver metastases)

In addition to the to use one form of highly effective contraception combined with a barrier method, female patients of childbearing potential must have a negative serum pregnancy test at screening (within 7 days of the start of treatment) and must not be breastfeeding.

Non-sterile men, who are not sexually abstinent and intend to be sexually active with a women of childbearing potential, must use a condom from the start of the trial and until 16 weeks after the last dose of treatment, or must practice total abstinence*** for the total duration of the study treatment and at least 3 months after the last dose of study treatment. Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception. Female partners of childbearing potential should consider the use of at least one contraception method describe above. If the female partner is pregnant, male participants should use a condom plus spermicide.

Total/true abstinence is defined as a patient who refrains from any form of sexual intercourse, and this is in line with their usual and/or preferred lifestyle.
