Brief Summary

Background: High-grade neuroendocrine carcinomas (HGNEC) are cancers that develop in different parts of the body, including the digestive tract, genitals, neck, and head. One drug (belinostat), combined with 2 other drugs (etoposide and cisplatin), is approved to treat HGNEC. But some people may have a gene variant that affects how quickly their body gets rid of the drug; these people may do better with different dosages of belinostat. Objective: To test higher or lower doses of belinostat based on gene variants in people with HGNEC. Eligibility: People aged 18 years and older with HGNEC. Design: Participants will be screened. They will have a physical exam with blood tests. Some blood will be used for genetic testing. They will have imaging scans and a test of their heart function. Samples of tumor tissue may be collected. All 3 study drugs (belinostat, etoposide, cisplatin) are given through a tube attached to a needle inserted into a vein. Treatment will be given in 21-day cycles. For cycles 1 through 6: Participants will come to the clinic for the first 4 days. They will be given all 3 drugs. Imaging scans and other tests will be repeated. Each visit will last 4 to 8 hours. After cycle 6: Participants may continue treatment with belinostat alone. They will come to the clinic for the first 3 days of each cycle. They may continue treatment for up to 5 years if the drug is helping them. Participants will have a follow-up visit 30 days after their last dose of belinostat. Then they will receive follow-up visits by phone or email every 3 to 6 months.

Outcome Measures

Primary Outcomes (1)

  • To determine if pharmacogenomic intervention can normalize the area under the curve (AUC) at cycle 6 between UGT1A1*28 and UGT1A1*60 genotypes) of belinostat administered as a continuous 48 h infusion in combination with cisplatin and etoposide

    Identified as the PK parameter of interest.

    Cycles 1-6 pre- and post- treatment with belinostat with all doses

Secondary Outcomes (4)

  • To determine efficacy with respect to objective response rate of belinostat administered as a continuous 48 h infusion in combination with cisplatin and etoposide

    Every 9 weeks while on study therapy

  • To determine the progression-free survival (PFS) and overall survival (OS) of belinostat administered as a continuous 48 h infusion in combination with cisplatin and etoposide

    PFS will be assessed from on-study date until date of progression or death without progression. Overall survival (OS) will be calculated from the on-study date until date of death. Until 3 years after last participant enrolled.

  • To assess duration of response of belinostat administered as a continuous 48 h infusion in combination with cisplatin and etoposide in platinum sensitive

    Until progression or the response is declared to have ended , if the participants have a PR or CR. Until 3 years after last participant enrolled.

  • To assess duration of response of belinostat maintenance

    Every 9 weeks while on monotherapy. Total study therapy will not exceed 5 years.

Eligibility Criteria

You may qualify if:
