Drug: [14C]-resminostat
Registration Number
NCT04955340
Lead Sponsor

Brief Summary

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.

  • History of a minimum of 1 bowel movement per day.

  • 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.
