About

Resminostat is a potent, orally available inhibitor of Class I, IIb and IV histone deacetylases (HDACs), including a pronounced activity against HDAC6. Resminostat targets epigenetic changes observed in tumour cells and has the potential to provide significant benefit to patients with advanced malignancies by inhibiting tumour progression and metastasis or even inducing tumour regression.

This will be a Phase 1, open-label, non-randomized, single dose study of the absorption, metabolism, excretion of [14C] resminostat following a single oral dose in healthy male participants.

The purpose of this study is to determine the absorption, metabolism, and excretion (AME) of [14C] resminostat and to characterize and determine the metabolites present in plasma, urine, and, where possible, faeces in healthy male participants following a single oral administration. Knowledge of the metabolism and excretion of parent drug and its metabolites is useful for evaluating the Metabolites in Safety Testing requirements elucidated in the International Conference on Harmonisation (ICH) M3, and the likelihood of effects of renal or hepatic impairment on the disposition of resminostat, and the likelihood for drug-drug interactions with resminostat. The results from this study may guide future study designs using special populations or evaluating the potential for drug-drug interactions.

Inclusion criteria

Male
Age between 35 (inclusive) and 55 years of age (inclusive)
Body mass index between 18.0 and 28.0 kg/m2, inclusive but at least 60 kg of body weight.
Healthy, as determined by no clinically significant findings from medical history, physical examination, 12-lead ECG, vital signs measurements, and clinical laboratory evaluations (congenital nonhemolytic hyperbilirubinemia [eg, suspicion of Gilbert Meulengracht's syndrome based on total and direct bilirubin] is not acceptable) at screening and/or check-in as assessed by the investigator (or designee).
Subjects must agree to use contraception
Able to comprehend and willing to sign an ICF and to abide by the study restrictions
History of a minimum of 1 bowel movement per day.
Subjects must agree not to donate sperm from check-in until 90 days after discharge.

Exclusion criteria

Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal, neurological, respiratory, endocrine, or psychiatric disorder, as determined by the investigator (or designee).
Any of the following abnormalities in laboratory test values and/or ECG at screening and/or check-in, confirmed by repeat: hemoglobin, white blood cell count, total platelets, and QTcF outside of normal range; alanine aminotransferase, aspartate aminotransferase, and creatinine values > upper limit of normal; and estimated glomerular filtration rate (calculated using Cockcroft-Gault formula) <60 mL/min.
History of significant hypersensitivity, intolerance, or allergy to any drug compound, food, or other substance, unless approved by the investigator (or designee).
History of stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs (uncomplicated appendectomy and hernia repair will be allowed).
Confirmed (eg, 2 consecutive measurements) systolic blood pressure >150 or <90 mmHg, diastolic blood pressure >90 or <50 mmHg, and pulse rate >90 or <40 beats per minute.
History of alcoholism or drug/chemical abuse within 2 years prior to screening.
Alcohol consumption of > 21 units per week. One unit of alcohol equals ½ pint (285 mL) of beer or lager, 1 glass (125 mL) of wine, or 1/6 gill (25 mL) of spirits.
Positive alcohol breath test result or positive urine drug screen (confirmed by repeat) at screening or check-in.
Positive hepatitis panel and/or positive human immunodeficiency virus test
Participation in a clinical study involving administration of an investigational drug (new chemical entity) in the past 90 days or 5 half-lives, whichever is longer prior to dosing.
Administration of any vaccination (including vaccines currently being deployed in the UK for SARS-CoV-27) within the past 90 days prior to dosing.
Use or intend to use any medications/products known to alter drug absorption, metabolism, and excretion processes, including St. John's wort, within 30 days prior to check-in, unless deemed acceptable by the investigator (or designee).
Use or intend to use any prescription medications/products within 14 days prior to check-in, unless deemed acceptable by the investigator (or designee).
Use or intend to use slow-release medications/products considered to still be active within 14 days prior to check-in, unless deemed acceptable by the investigator (or designee).
Use or intend to use any nonprescription medications/products including vitamins, minerals, and phytotherapeutic/herbal/plant-derived preparations within 7 days prior to check-in, unless deemed acceptable by the investigator (or designee).
Use of tobacco- or nicotine-containing products within 3 months prior to check-in, or positive cotinine test at screening or check-in.
Ingestion of poppy seed-, Seville orange-, or grapefruit-containing foods or beverages within 7 days prior to check-in.
Receipt of blood products within 2 months prior to check-in.
Donation of blood from 3 months prior to screening, plasma from 2 weeks prior to screening, or platelets from 6 weeks prior to screening.
Poor peripheral venous access
Subjects with exposure to significant diagnostic or therapeutic radiation (eg, serial X-ray, computed tomography scan, barium meal) or current employment in a job requiring radiation exposure monitoring within 12 months prior to check-in.
Subjects who have participated in any clinical study involving a radiolabeled investigational product within 12 months prior to check-in.
Subjects who, in the opinion of the investigator (or designee), should not participate in this study.
