Brief Summary:
This phase I trial tests the safety, side effects, and best dose of ZEN003694 in combination with Binimetinib in treating patients with solid tumors that carry RAS alterations and that have spread to other places in the body (advanced/metastatic) or cannot be removed by surgery (unresectable). ZEN003694 is an oral medication with potential anticancer activity. It is an inhibitor of a family of proteins called bromodomain and extra-terminal (BET) which play important role during development and cellular growth. ZEN003694 may stop the growth of tumor cells that produce BET. Binimetinib is in a class of medications called kinase inhibitors. It works by blocking the action proteins called MEK1 and MEK2, that signal cancer cells to multiply. It may help keep cancer cells from growing and spreading. There is pre-clinical evidence that using ZEN003694 and binimetinib together may shrink or stabilize cancers studied in this trial. There are two parts of this study; dose escalation and dose expansion. In the dose escalation part of this study, different people will get different doses of the study drugs ZEN003694 and binimetinib. In the dose expansion part of this study, the highest dose with manageable side effects will be given to additional people. This will help to understand the side effects that may happen with this drug combination.

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) of BET bromodomain inhibitor ZEN-3694 (ZEN003694 [ZEN-3694]) and binimetinib when given in combination in patients with advanced or metastatic solid tumors with rat sarcoma virus oncogene homolog (RAS) pathway alterations. (Part 1 [Dose Escalation]) II. To evaluate the safety and toxicity of ZEN003694 (ZEN-3694) and binimetinib when given in combination. (Part 2 [Dose Expansion])

SECONDARY OBJECTIVES:

I. To determine the safety and tolerability of ZEN003694 (ZEN-3694) and binimetinib when given in combination in patients with advanced or metastatic solid tumors with RAS pathway alterations. (Part 1 [Dose Escalation]) II. To characterize the pharmacokinetics (PK) of ZEN003694 (ZEN-3694) when given in combination with binimetinib. (Part 1 [Dose Escalation]) III. To observe and record the preliminary antitumor activity of ZEN003694 (ZEN-3694) and binimetinib when given in combination. (Part 1 [Dose Escalation]) IV. To determine the effects of ZEN003694 (ZEN-3694) and binimetinib when given in combination on patient survival and other metrics of clinical activity. (Part 2 [Dose Expansion]) IVa. To evaluate objective response rate (ORR). IVb. To evaluate progression-free survival (PFS). IVc. To evaluate duration of response (DOR). IVd. To evaluate disease control rate (DCR) at 4 months.

EXPLORATORY OBJECTIVES:

I. To characterize the PK of the ZEN003694 (ZEN-3694) and binimetinib combination. (Part 2 [Dose Expansion]) II. To identify biomarkers of sensitivity and response to the ZEN003694 (ZEN-3694) and binimetinib combination. (Part 2 [Dose Expansion]) III. To determine histone H3 acetylated at lysine 27 (H3K27ac) levels via chromatin immunoprecipitation sequencing (ChIPseq) on tumor biopsy specimen. (Part 2 [Dose Expansion]) IV. To determine the open chromatin regions in response to the ZEN003694 (ZEN-3694) and binimetinib combination using assay for transposase-accessible chromatin sequencing (ATACseq). (Part 2 [Dose Expansion])

OUTLINE: This is a dose-escalation study of ZEN-3694 with fixed dose binimetinib followed by a dose expansion.

Patients receive ZEN-3694 orally (PO) once daily (QD) and binimetinib PO twice daily (BID) on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. During the dose expansion phase, patients will have two mandatory biopsies - one before beginning the study and the second at day 15 of cycle 1. The study biopsy takes small pieces of cancer tissue from patient's body to look for markers (substances made by, on, or in tumor cells) related to how the study treatment works.

After completion of study treatment, patients are followed up every 3 months for up to 2 years.

Primary Outcome Measures :
  1. Incidence of dose limiting toxicities (Part 1 [Dose Escalation]) [ Time Frame: Up to 28 days from treatment start date ]
    Defined as the incidence of clinically significant adverse events or abnormal laboratory values thought to be at least possibly related to the study treatment occurring during the first cycle.

  2. Incidence of adverse events (Part 2 [Dose Expansion]) [ Time Frame: Up to 30 days after last treatment dose ]
    Including but not limited to treatment-emergent AEs, severe adverse events (SAEs), deaths, and clinical laboratory abnormalities, as assessed by the NCI CTCAE v5.0.


Secondary Outcome Measures :
  1. Incidence of adverse events (AEs) (Part 1 [Dose Escalation]) [ Time Frame: Up to 30 days after last treatment dose ]
    Toxicity will be graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v)5.0. Toxicity will be summarized by grade and type using descriptive statistics, including frequency and 95% confidence interval.

  2. Pharmacokinetic (PK) parameters (Part 1 [Dose Escalation]) [ Time Frame: Days 2, 8, 15, and 16 of cycle 1 ]
    PK parameters will be estimated using non-compartmental method(s) and correlated with PD endpoints using non-parametric statistics.

  3. Overall response rate (ORR) [ Time Frame: Up to 2 years from treatment start date ]
    Defined as the percentage of participants who have a partial or complete response to the treatment. Descriptive statistics will be used to summarize ORR.

  4. Disease control rate (DCR) [ Time Frame: Up to 4 months from treatment start date ]
    Defined as the percentage of participants that have achieved complete response, partial response or stable disease after treatment. Descriptive statistics will be used to summarize DCR.

  5. Duration of response (DOR) [ Time Frame: Up to 2 years from treatment start date ]
    Defined as the length of time from treatment start date during the which the tumor does not grow. Kaplan-Meier method will be used to estimate DOR.

  6. Progression free survival (PFS) [ Time Frame: Up to 2 years from treatment start date ]
    Defined as the length of time during and after the study treatment during which the tumor does not grow. Kaplan-Meier method will be used to estimate PFS.

This exception does not include carcinomatous meningitis, which is excluded regardless of clinical stability
  • 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 study

  • Ability to understand and the willingness to sign a written informed consent document. Participants with impaired decision-making capacity (IDMC) who have a legally authorized representative (LAR) and/or family member available will also be eligible

Exclusion Criteria:

  • Patients who have not recovered from AEs due to prior anticancer therapy (i.e., have residual toxicities > Grade 1) with the exception of alopecia
  • Patients who are receiving any other investigational agents
  • Breast cancer patients with a prior history of hormone receptor positivity will not be eligible

  • Patients with uncontrolled intercurrent illness
  • Patients with psychiatric illness/social situations that would limit compliance with study requirements
  • Pregnant women are excluded from this study because ZEN003694 (ZEN-3694) and binimetinib are a BETi and MEK inhibitor agent, respectively, with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for AEs in nursing infants secondary to treatment of the mother with ZEN003694 (ZEN-3694) and binimetinib, breastfeeding should be discontinued if the mother is treated with ZEN003694 (ZEN-3694) and binimetinib
  • Patient has a history of cerebrovascular accident, myocardial infarction, or unstable angina within the previous 6 months prior to study treatment initiation
  • Patients with any medical condition or diagnosis that would likely impair absorption of an orally administered drug (e.g., gastrectomy, ileal bypass, chronic diarrhea, gastroparesis) are excluded
  • Patient has a history of retinal vein occlusion
  • Patient has a history of pneumonitis or interstitial lung disease
