A Randomized, Single-Dose, Comparative, Positive and Placebo Controlled, Four-Way, Four Period, Cross-Over Study to Evaluate the Effect of DIC075V on QTc Intervals in Healthy Subjects

Completed · Phase 1 · Has a placebo group

Conditions studied: Ventricular Repolarization

In brief

This study is conducted to evaluate the effectiveness of DIC075V on ventricular repolarization in healthy subjects compared to placebo after a single dose of DIC075V administered intravenously (IV) and to evaluate ECG assay sensitivity by evaluating the baseline-adjusted effect of a single oral (PO) moxifloxacin 400 mg dose on ventricular repolarization in healthy subjects compared to placebo. Other secondary objectives are as follows: * To evaluate the effect of DIC075V on ventricular repolarization in healthy subjects compared to placebo at the Tmax of diclofenac and hydroxypropyl-β-cyclodextrin (HPβCD). * To determine if there is a pharmacokinetic/pharmacodynamic (PK/PD) relationship between the duration of the QTc intervals and diclofenac and HPβCD plasma concentrations. * Obtain additional pharmacokinetic (PK) information on diclofenac and HPβCD in healthy subjects. * Provide additional safety information.

• Normal 12-lead ECG (QTc interval <450 millisecond (ms) for males and <470 ms for females):
• Consistent sinus rhythm
• No clinically significant conduction disorders
• PR interval between 120 and 230 ms
• HR ≤100 bpm and ≥40 bpm
• QRS interval ≤110 ms
• QT intervals that can be consistently analyzed.
• No medical history of cardiac disease or a family history of QT prolongation.
• No clinically significant electrolyte abnormality.
• Subjects with a calculated creatinine clearance greater than >80 ml/min.
• Female subjects who are of childbearing potential with a negative serum pregnancy test at Screening and at Check-in who are either sexually inactive (abstinent) for 14 days prior to Screening and throughout the study or are using two of the following acceptable birth control methods:
• Intrauterine device (IUD) in place for at least 2 months prior to Study Day -2;
• Barrier method (condom or diaphragm) with spermicide for at least 14 days prior to screening through study completion;
• Hormonal contraceptive for at least 3 months prior to Study Day -2 through completion of study;
• Surgical sterilization (vasectomy) of partner at least 6 months prior to Study Day -2.

• Naturally postmenopausal for a minimum of 2 consecutive years prior to Study Day -2;
• Surgically sterile (bilateral tubal ligation with surgery at least 6 months prior to Study Day -2, hysterectomy, or bilateral oophorectomy with surgery at least 2 months prior to Study Day -2).

You may not qualify if…

• History or presence of significant cardiovascular, pulmonary, hepatic, renal, hematologic, gastrointestinal, endocrine, immunologic, dermatologic, neurologic, or psychiatric disease.
• History of invasive cancer within the past 5 years (excluding non-melanoma skin cancers).
• History of hypersensitivity or allergy to the quinolone class of antibiotics; to diclofenac or other NSAIDs; or to HPβCD or other excipients in DIC075V (monothioglycerol, sodium hydroxide, hydrochloric acid, and water for injection).
