About
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.
Full description
Background:
- Extrapulmonary High-Grade Neuroendocrine Neoplasms (HGNENs) are all high-grade neoplasms that may resemble small cell carcinoma or large cell Neuroendocrine Carcinomas (NEC) of the lung. Poorly differentiated NECs are often associated with a rapidly progressive disease and a proliferative rate (Ki67%) >20%.
- As a general rule, poorly differentiated NECs are treated with platinum-based regimens according to small cell carcinoma guidelines.
- This protocol will study a continuous infusion of the histone deacetylase (HDAC) inhibitor belinostat in combination with cisplatin and etoposide for patients with advanced neuroendocrine neoplasms.
Objective:
-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 in participants with neuroendocrine malignancies based on UGT1A1*28 and UGT1A1*60 genotypes.
Eligibility:
- The protocol will be open to participants with Extrapulmonary High-Grade Neuroendocrine Neoplasms (HGNENs)
- Participants will be recruited based on genotype, with n=9 carrying UGT1A1*1/*1 or UGT1A1*1/*28 and n=30 carrying any other combination of variant alleles at UGT1A1*28 or UGT1A1*60.
- Age >=18 years
- ECOG Performance Status 0-2
Design:
- Parallel design in which the starting dose of belinostat is administered as a 48-hour continuous infusion at two possible doses based on genotype: 1) 400mg/m^2/day for UGT1A1*28/*28 or at least one UGT1A1*60 allele UGT1A1*28 and UGT1A1*60 genotypes or 2) 600 mg/m^2/day for wild-type participants and those carrying UGT1A1*1/*28 in the absence of other variant alleles.
- To define pharmacokinetics, toxicities of belinostat provided to participants who carry the above genotype groups.
- All participants will also receive cisplatin at 60 mg/m^2 IV on day 2, and etoposide at 80 mg/m^2 IV daily x3 on days 2 - 4.

Participants must have histologically confirmed diagnosis of Extrapulmonary High-Grade Neuroendocrine Neoplasms (HGNENs) for which there is no known standard therapy capable of extending life expectancy.
-
Age >= 18 years.
-
Participants with neuroendocrine prostate cancer may continue ongoing LHRH agonist therapy.
-
Participants with bone metastases or hypercalcemia who began intravenous bisphosphonate treatment prior to study entry may continue this treatment while on study.
-
Evaluable (measurable or non-measurable) disease, per RECIST 1.1.
-
ECOG performance status <=2 at screening
-
Participants must have adequate organ and marrow function as defined below:
- Leukocytes >=3,000/mcL
- Hemoglobin >= 10 g/dL
- Absolute neutrophil count (ANC) >=1,500/mcL
- Platelets >=100,000/mcL
- Aspartate aminotransferase (AST) or serum glutamic-oxaloacetic transaminase (SGOT) / Alanine aminotransferase (ALT) or serum glutamic-pyruvic transaminase (SGPT): <=3 X institutional upper limit of normal
- Total bilirubin <= 1.5 x institutional upper limit of normal (ULN).
NOTE: In participants with Gilbert s syndrome, a total bilirubin <= 3.0 X ULN is allowed
- Serum Creatinine <= 1.5 X institutional ULN OR
- An estimated Creatinine clearance (CrCL) >=60 mL/min/1.73 m^2 based on the Cockcroft Gault equation
- Prothrombin time (PT) / International normalized ratio (INR) and Partial thromboplastin time (PTT) <= 1 X institutional ULN

Women of child-bearing potential (WOCBP) must agree to use effective contraception (hormonal, intrauterine device (IUD), tube ligation, a partner has had a previous vasectomy, abstinence) prior to study entry, during the study, and for 14 months for women after the last dose of the study drug(s). Men with partners of childbearing potential must agree to use effective contraception (abstinence, condoms, previous vasectomy) or request partners to use effective contraception (per above) during the study and for 11 months after the last dose of study therapy.
