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

Официальное название

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

Обзор

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.

Подробное описание

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.

Критерии участия

Критерии включения

• Dose Escalation additional criteria: Patients must have histologically confirmed cancer that is metastatic or unresectable and must have progressed on standard therapies which would have included fluorouracil (5-FU) or capecitabine
• Dose Escalation additional criteria specifically for colorectal cancer (CRC) patients: Willingness and ability to undergo a pre-treatment biopsy
• Dose Expansion additional criteria: Patients must have histologically confirmed CRC that is metastatic or unresectable and must have progressed on standard therapies which would have included 5-FU or capecitabine
• 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
• Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 (Karnofsky >= 60%)
• Availability of archival tumor tissue at the time of patient enrollment for molecular profiling studies
• Prior to study dosing, previous systemic therapy must have been completed for at least five half-lives or 2 weeks, whichever is shorter

• 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

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
