Testing the Addition of an Anti-Cancer Drug, ZEN003694, to the Usual Chemotherapy Treatment (Capecitabine) for Metastatic or Unresectable Cancers

March 8, 2024 updated by: National Cancer Institute (NCI)

Phase I Trial of ZEN003694 (ZEN-3694) in Combination With Capecitabine in Patients With Solid Tumors

This phase I trial tests the safety, side effects, and best dose of ZEN003694 in combination with the usual treatment with capecitabine in treating patients with cancer that has spread from where it first started (primary site) to other places in the body (metastatic) or cannot be removed by surgery (unresectable) and that it has progressed on previous standard treatment. ZEN003694 is an inhibitor of a family of proteins called the bromodomain and extra-terminal (BET). It may prevent the growth of tumor cells that over produce BET protein. Capecitabine is in a class of medications called antimetabolites. It is taken up by cancer cells and breaks down into fluorouracil, a substance that kills cancer cells. Giving ZEN003694 in combination with capecitabine may be safe in treating patients with metastatic or unresectable solid tumors.

Detailed Description

PRIMARY OBJECTIVE:

I. To determine the safety and tolerability, maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of BET bromodomain inhibitor ZEN-3694 (ZEN003694 [ZEN-3694]) in combination with capecitabine in patients with solid tumors.

SECONDARY OBJECTIVES:

I. To observe and record anti-tumor activity of ZEN003694 (ZEN-3694) in combination with capecitabine.

II. To determine the pharmacokinetics (PK) of ZEN003694 (ZEN-3694) in combination with capecitabine.

III. To determine the pharmacodynamics (PD) of ZEN003694 (ZEN-3694) in combination with capecitabine (death receptor 5 [DR5] dynamics and apoptosis).

IV. To identify molecular subpopulations particularly sensitized to bromodomain and extra-terminal motif inhibitor (BETi) and capecitabine.

OUTLINE: This is a dose-escalation study of ZEN003694 and capecitabine, followed by a dose-expansion study.

Patients receive ZEN003694 orally (PO) once daily (QD) and capecitabine PO twice daily (BID) 2 weeks on, 1 week off during each treatment cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients undergo computed tomography (CT) or magnetic resonance imaging (MRI), positron emission tomography (PET)/CT, and collection of blood samples throughout the trial. Patients may also undergo biopsies during screening and while on the study.

After completion of study treatment, patients are followed up for safety 30 days after the last dose, and then every 3 months for 12 months.

  • Dose Expansion additional criteria: Willingness and ability to undergo pre- and on- treatment biopsies
  • Patients must have measurable disease
  • Age >= 18 years. Because no dosing or adverse event data are currently available on the use of ZEN003694 (ZEN-3694) in combination with capecitabine in patients < 18 years of age, children are excluded from this study

  • Glomerular filtration rate (GFR) >= 50 mL/min/1.73 m^2
  • Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial
  • For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated

  • Patients should be New York Heart Association Functional Classification of class 2B or better
  • The effects of ZEN003694 (ZEN-3694) and capecitabine on the developing human fetus are unknown. For this reason and because BET inhibitors as well as 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. Women of child-bearing potential and 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 6 months after completion of ZEN003694 (ZEN-3694) and capecitabine administration
  • Ability to understand and the willingness to sign a written informed consent document. Legally authorized representatives may sign and give informed consent on behalf of study participants

Exclusion Criteria:

  • Previous treatment with BET inhibitors
  • History of inability to tolerate capecitabine at the projected treatment dose on this trial
  • Use of oral Factor Xa inhibitors (i.e., rivaroxaban, apixaban, betrixaban, edoxaban otamixaban, letaxaban, eribaxaban) and Factor IIa inhibitors (i.e., dabigatran). Low molecular weight heparin is allowed

  • Patients who are receiving any other investigational agents
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to ZEN003694 (ZEN-3694) or other agents used in study
  • Patients receiving any medications or substances that are strong inhibitors or inducers of CYP3A4 are ineligible. Strong inhibitors of CYP3A4 must be discontinued at least 7 days, and inducers 14 days prior to the first dose of ZEN003694 and capecitabine. Substrates of CYP1A2 with narrow therapeutic window must be avoided while taking ZEN003694
  • Pregnant women are excluded from this study because ZEN003694 (ZEN-3694) 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 ZEN003694 (ZEN-3694), breastfeeding should be discontinued if the mother is treated with ZEN003694 (ZEN-3694). These potential risks may also apply to other agents used in this study

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence of adverse events
Time Frame: Up to 30 days after last dose
Adverse events and serious adverse events will be tabulated for each dose levels. As per National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0, the term toxicity is defined as adverse events that are classified as either possibly, probably, or definitely related to study treatment. The maximum grade for each type of toxicity will be recorded for each patient, and frequency tables will be reviewed to determine toxicity patterns.
Up to 30 days after last dose
Maximum tolerated dose (MTD)
Time Frame: Up to 30 days after last dose
Defined as the highest dose level with no more than 1/6 dose-limiting toxicity.
Up to 30 days after last dose
Recommended phase 2 dose (RP2D)
Time Frame: Up to 30 days after last dose
Will be determined based on the MTD and later cycle adverse event (AE) rates.
Up to 30 days after last dose
