NCT05691504 | RECRUITING | Advanced Endometrial Carcinoma

Testing the Combination of APG-1252 (Pelcitoclax) and Cobimetinib in Recurrent Ovarian and Endometrial Cancers
Sponsor:

National Cancer Institute (NCI)

Brief Summary:

This phase I trial tests the safety, side effects, and best dose of combination therapy with pelcitoclax (APG-1252) and cobimetinib in treating patients with ovarian and endometrial cancers that have come back after a period of improvement (recurrent). APG-1252 is a drug that inhibits activity of proteins that prevent cell death, leading to increased cell death and reduced cell growth. Cobimetinib is used in patients whose cancer has a mutated (changed) form of a gene called BRAF. It is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells. Giving APG-1252 in combination with cobimetinib may shrink or stabilize tumor in patients with recurrent ovarian and endometrial cancers.

Detailed Description:

PRIMARY OBJECTIVE: I. To establish the recommended phase 2 dosing (RP2D) for combination pelcitoclax (APG-1252) and cobimetinib in advanced/recurrent endometrial and ovarian cancers. SECONDARY OBJECTIVES: I. To observe and record anti-tumor activity. II. To assess the side effects associated with combination APG-1252 and cobimetinib in advanced/recurrent endometrial and ovarian cancers, as measured by treatment-emergent and treatment-related adverse events by Common Terminology Criteria for Adverse Events (CTCAE) criteria. III. To assess the activity of combination APG-1252 and cobimetinib in advanced/recurrent endometrial and ovarian cancers, via measures of clinical activity, including response rate (RR), progression-free survival (PFS), clinical benefit rate (CBR), and duration of response (DoR). TRANSLATIONAL OBJECTIVES: I. To evaluate the pharmacodynamic effects of combination APG-1252 and cobimetinib on BCL-xL activity, including BCL-xL:BAX and BCL-xL-BAK heterodimers, as measured by the National Clinical Laboratory Network (NCLN) apoptosis multiplex immunoassay. II. To evaluate markers of response and resistance to APG-1252 and cobimetinib via whole exome sequencing and ribonucleic acid (RNA) sequencing obtained in pre-treatment/archival and on-treatment samples. III. To explore the effect of combination APG-1252 and cobimetinib on RAS pathway signaling, as measured by the NCLN ERK/MEK multiple immunoassay, and the association between RAS pathway activation with activity of combination APG-1252 and cobimetinib. IV. To explore markers of response and resistance to APG-1252 and cobimetinib through evaluation of BIM and MCL1 expression and RAS pathway signaling by reverse phase protein array (RPPA) and by BIM and pERK expression by immunohistochemistry. V. To determine pharmacokinetic (PK) parameters of APG-1252 and cobimetinib in combination. VI. To investigate RAS allelic burden and resistance mutations in patients receiving combination APG-1252 and cobimetinib. OUTLINE: This is a dose-escalation study of APG-1252 and cobimetinib followed by a dose-expansion study. Patients receive APG-1252 intravenously (IV) once a week (Q7D). Patients also receive cobimetinib orally (PO) once a day (QD) on days 1-21 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo biopsy and collection of blood on study and undergo computed tomography (CT) and/or magnetic resonance (MRI) throughout the trial. Patients undergo echocardiography (ECHO) or multigated acquisition scan (MUGA) during screening and on study. Patients are followed for up to 30 days after removal from study therapy.

Criteria
Inclusion Criteria
  • * For dose escalation, patients must have histologically or cytologically confirmed recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer, or endometrial cancer that is metastatic or unresectable and for which standard curative or palliative measures do not exist or are no longer effective. For expansion, patients must have histologically or cytologically confirmed recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer
  • * Prior lines
    • * Patients must have received at least one prior line of platinum-based systemic therapy. Platinum received together with radiation as a sensitizing agent is not considered a systemic line of therapy
    • * Patients with low grade serous ovarian cancer must have received a prior MEK inhibitor at a demonstrated therapeutic dose (i.e., trametinib 1mg daily or higher; binimetinib 30mg twice daily or higher). Patients who have had prior cobimetinib must have been able to tolerate cobimetinib at the dose and schedule they would receive it on study
    • * Patients with microsatellite instability (MSI) or mismatch repair deficient (dMMR) endometrial cancer must have received prior PD-1 or PD-L1 directed immunooncology (IO) therapy or be considered medically ineligible to receive such therapy
    • * Patients with ovarian cancer must have platinum-resistant disease (progression within 6 months of last receipt of platinum)

    • * Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
    • * Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, patients should be class 2B or better
    • * Patients should be able to swallow oral therapy
    • * The effects of APG-1252 on the developing human fetus are unknown. For this reason and because other therapeutic agents used in this trial are known to be 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 and for the duration of study participation and for 2 weeks after completion of APG-1252 and cobimetinib administration. 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 2 weeks after completion of APG-1252 and cobimetinib administration
    • * Ability to understand and the willingness to sign a written informed consent document. Participants with impaired decision-making capacity who have a legally-authorized representative (LAR) and/or family member available will also be eligible
    • * Patients must be willing to release archival tissue if available
    • * Patients on dose level 2 or higher in the escalation cohort and patients in the expansion cohort must have measurable and biopsiable disease (in a lesion that is not being utilized as a target lesion for Response Evaluation Criteria in Solid Tumors \[RECIST\] assessment)
    Exclusion Criteria
    • * Potential trial participants should have recovered from clinically significant adverse events of their most recent therapy/intervention prior to enrollment. Patients who have previously received cancer-directed therapeutic agents with the potential for CYP3A4 interaction will be eligible if at least 5 half-lives have elapsed before enrollment
    • * Patients who have not recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities \> grade 1) with the exception of alopecia

Strong inhibitors or inducers of CYP3A4 must be discontinued at least 7 days prior to the first dose of APG-1252 and cobimetinib. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. 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
    • * Patients with uncontrolled intercurrent illness
    • * Patients with evidence of retinal pathology on ophthalmologic examination; or neurosensory retinal detachment, right ventricular outflow (RVO), or neovascular macular degeneration
    • * Pregnant women are excluded from this study because APG-1252 is an agent 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 APG-1252, breastfeeding should be discontinued if the mother is treated with APG-1252. These potential risks may also apply to other agents used in this study
    • * Patients with prior exposure to BCL family inhibitors
    • * Patients with any gastrointestinal (GI) disorder that may affect absorption of cobimetinib and other oral medications in the opinion of the treating investigator, such as malabsorption syndrome, major bowel or stomach resection, evidence of small or large bowel obstruction within the past 3 months
    • * Patients who have a dependence on IV fluids or total parenteral nutrition
