Official title
Phase 2 Multi-Center, Dose Escalation Trial To Assess The Safety And Effectiveness Of Bucillamine On Urinary Cystine Excretion And Cystine Capacity In Patients With Cystinuria
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Subjects on a standard regimen of tiopronin (cystine binding thiol drug; CBTD) plus prescribed first-line therapy (i.e. on a hydration, alkali therapy and dietary restriction) who are failing therapy will be selected for this trial. After completing informed consent, the subject will have Screening consisting of medication history and physical examination with vital signs. Samples of blood and urine will be taken for clinical laboratory and urinalysis. Patients will undergo a 12-lead ECG test. A history of side effects with current CBTD as well as laboratory recordings of abnormalities attributable to treatment will also be recorded. Subjects will be dosed in a sequential manner, starting with the low dose group (300 mg/day), then proceeding to the 600 mg.day dose group.. Safety and tolerability will be monitored closely by an Independent Medical Monitor (IMM) and based on the IMM's assessment that it is safe to proceed to the higher dose (600 mg/day), subsequent subjects will be enrolled into that group. Up to 15 subjects each will be enrolled into either Group A or Group B. After 7 days on the assigned bucillamine dose, a 24-hour urine sample will be taken and after completing the Day 8 safety visit, subjects will undergo a 7 day washout where no CBTDs will be taken. Thereafter, subjects will be allowed to resume their originally prescribed CBTDs under Investigator's supervision. One week following study drug discontinuation, subjects will return to the clinic for follow-up safety assessments.
