For Healthy Volunteers and Post-Herpetic Neuralgia Patients
All participants (excluding those who are exclusively in same-sex relationships, who are postmenopausal or have an exclusive partner who is postmenopausal) must agree to use a highly effective method of contraception throughout the study and for at least 30 days for females or 90 days for males after the last dose of IP. Female participants must not be breastfeeding, lactating, or pregnant during the study period.
Female participants are required to be on their chosen contraceptive for at least 7 days before dosing.
Female participants, where their sole, male sexual partner is vasectomized, must provide a verbal confirmation of azoospermia (90 days following the procedure) which should be recorded in the source documents by the Investigator.
The minimum timeframe for pre-dose vasectomy for male participants is ≥ 12 weeks, unless they are the sole sexual partner of a female participant as outlined above.
Male participants who are sexually active must use a condom combined with use of a highly-effective method of contraception for the female partner (excluding those who have had a vasectomy or whose partner is postmenopausal). Confirmation of the female partner's contraceptive information must be provided verbally by the male participant and should be recorded in the source documents by the Investigator. The postmenopausal status of the female partner must be confirmed verbally by the male participant and should be recorded in the source documents by the Investigator.
In good general health at the Investigator's discretion, with no significant medical history, and with no clinically significant abnormalities on physical examination at Screening and before the first dose of IP.
