Who can take part
You may be able to join if
- 1. Male or female, aged 19 to 80 years of age (inclusive)
- 2. Has provided written informed consent for the study
- 3. Clinical diagnosis of post herpetic neuralgia, with pain persisting for at least 3 months after the onset of herpes zoster rash, and having received treatment for at least 1 month (with supporting documentation such as a referral letter).
- 4. Average NRS score (on an 11-point scale) for the week prior to baseline is ≥4 and <9, and < 40% reduction at the end of administration compared to before placebo administration (at least 5 days score out of 7 days score entries from day -7 to day -1 are required)
- 5. Has a body mass index (BMI) between ≥18 kg/m2 and <40 kg/m2 (inclusive) at the time of Screening, and a minimum weight of 45 kg.
- 6. If participant is of childbearing potential, is practicing a highly effective method of birth control throughout the study and for at least 30 days for females and 90 days for males after the last dose of IP. The following are considered highly effective methods of birth control: • Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation o oral o intravaginal o transdermal • Progestogen-only hormonal contraception associated with inhibition of ovulation o oral o injectable o implantable • Intrauterine device • Intrauterine hormone-releasing system • Bilateral tubal occlusion • Vasectomized partner (vasectomized partner is a highly effective birth control method provided that partner is the sole sexual partner of the study participant and that the vasectomized partner has received medical assessment of the surgical success) • Sexual abstinence, defined as refraining from heterosexual intercourse during study participation, is acceptable if this is the participant’s usual lifestyle; periodic abstinence (calendar, symptothermal, postovulation methods), withdrawal (coitus interruptus), spermicides only, and the lactational amenorrhea method are not acceptable methods of contraception Note: A participant is considered to be of childbearing potential if they are postmenarchal and premenopausal, unless surgically sterile (permanent sterilization methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy). A postmenopausal state is defined as no menses for at least 1 year without an alternative medical cause.
You likely can't join if
