Treatment Group

EXPERIMENTAL

Five sites will be repeatedly injected with Rcombinant botulinum neurotoxin type A for injection (YY001) at 0.05 mL each, 2 sites in corrugator muscle of each side and 1 site in the procerus muscle, for a total dose of 20U.The study period is up to 64 weeks, divided into 5 treatment cycles.

Biological: Rcombinant botulinum neurotoxin type A for injection (YY001)

Interventions

Five sites will be injected at 0.05 mL each, 2 sites in corrugator muscle of each side and 1 site in the procerus muscle, for a total dose of 20U.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female 18 to 65 years (inclusive) at the time of signing the informed consent form.
  • At screening or baseline, participants who complete all visits of the REFINE study without major protocol deviations and SAEs
  • Agree to participate in the study and sign the informed consent form.
  • At the discretion of the investigator, the participants can comply with the protocol requirements.
  • Females and/or males of childbearing potential and their partners: those who should be using effective contraception and have no plans for childbearing, egg donation (females), or sperm donation (males) from the signing of the informed consent form to 3 months after the last administration. female participants of childbearing potential must have had a negative blood pregnancy test (human chorionic gonadotropin) within 7 days prior to the first administration of study drug or a Urine pregnancy test examination must be negative 3 days prior to the first administration of study drug.
  • Note:
  • Women of childbearing potential are those who have experienced menarche, have not undergone sterilization (hysterectomy or bilateral salpingo-oophorectomy or bilateral tubal ligation), and are not in a state of post-menopausal (defined as absence of menstrual bleeding for 12 months prior to screening, without any other medical reason).
  • Effective contraceptives include: vasectomy, abstinence, intrauterine devices, hormones \[oral, patch, ring, injections, implants\], barrier methods \[diaphragm, cervical cap, sponge, condom\].

You may not qualify if:

  • Use of medications or treatments prohibited by the REFINE study protocol.
  • Any condition that required permanent discontinuation of study treatment during the REFINE study.
  • Use of nonsteroidal anti-inflammatory drugs including aspirin or anticoagulants within 1 week prior to baseline.
  • Abnormal laboratory tests that, in the assessment of the investigator, are not appropriate for participation in this study: including, but not limited to: alanine aminotransferase (ALT)/aspartate aminotransferase (AST) ≥ 2.5 times the upper limit of the normal range (×ULN), creatinine ≥ 2 ×ULN, urea/urea nitrogen ≥ 2 ×ULN.
  • Female who is pregnant or breast feeding.
