A Study to Assess the Safety and Efficacy of IPN10200 in Adult Participants With Moderate to Severe Upper Facial Lines

The purpose of this study is to assess the safety and efficacy profile of increasing doses of IPN10200 in comparison to placebo, with the aim to discover the doses(s) that offer the best efficacy/safety profile when used for the treatment of moderate to severe Upper Facial Lines.

This study will be conducted in three stages. The full study (including all stages) will have a maximum 547 participants. The protocol is currently approved up to stage 1, step 1 and stage 1/ step 2.

Stage 1 (phase Ib \& II)

* Step 1 (Phase Ib): a dose-escalation first-in-human step in participants with moderate to severe Glabellar Lines (GL)
* Step 2 (Phase II): dose finding step in participants with moderate to severe GL as compared with Dysport

Stage 2 (phase II)

- An evaluation of efficacy and safety of IPN10200 in one of the following regions: GL + forehead lines (FHL) or lateral canthal lines (LCL)

Stage 3 (phase II)

- A safety and efficacy evaluation of IPN10200 in all three regions (GL, FHL and LCL)


Eligibility Criteria:
Inclusion Criteria:

1. Participant must be 18 to 65 years of age inclusive, at the time of signing the informed consent.
2. Moderate or severe (Grade 2 or 3) GL at maximum contraction at Baseline, as assessed by the ILA using a validated 4-point photographic scale.
3. Moderate or severe (Grade 2 or 3) GL at maximum contraction at Baseline, as assessed by the SSA using a validated 4-point categorical scale.
4. Dissatisfied or very dissatisfied (Grade 2 or 3) with their lines at Baseline, as assessed by the SLS.

Exclusion Criteria:

1. An active infection or other skin problems in the upper face including the GL, FHL, and LCL area (e.g. acute acne lesions or ulcers).
2. A history of eyelid blepharoplasty or brow lift within the past 5 years
3. A history of facial nerve palsy.
4. Marked facial asymmetry, ptosis, excessive dermatochalasis, deep dermal scarring, or thick sebaceous skin.
5. Any known medical condition that may put the participant at increased risk in regard to exposure to BoNT of any serotype (i.e. myasthenia gravis, Eaton-Lambert syndrome, amyotrophic lateral sclerosis, etc.)
6. Has COVID-19 illness or a know positive SARS-CoV-2 test, or the presence of any other condition (e.g. neuromuscular disorder or other disorder that could interfere with neuromuscular function)
7. Previous treatment with any BoNT serotype for Stage 1 / Step 1 or any recent reatment (within the past 6 months prior to baseline) with any BoNT serotype for Stage 1 / Step 2.
8. Any prior treatment with permanent fillers in the upper face including the GL, FHL and LCL area.
9. Any prior treatment with long lasting dermal fillers in the upper face including the GL area within the past 3 years and/or skin abrasions/resurfacing (whatever the interventional technic used) within the past 5 years, or photo rejuvenation or skin/vascular laser intervention within the 12 months prior to Baseline.
10. Any planned facial cosmetic surgery during the study.
11. Use of concomitant therapy which, in the investigator's opinion, would interfere with the evaluation of the safety or efficacy of the study intervention, including medications affecting bleeding disorders (e.g. antiplatelet agents and/or anticoagulants given for treatment or prevention of cardiovascular/cerebrovascular diseases).
12. Use of medications that affect neuromuscular transmission, such as curare-like non depolarising agents, lincosamides, polymyxins, anticholinesterases and aminoglycoside antibiotics, within the past 30 days prior to Baseline.
13. Use of any experimental device within 30 days or use of any treatment with an experimental drug within five times the documented terminal half-life of the respective drug or its metabolites or if the halflife is unknown within 30 days prior to the start of the study (prior to Baseline) and during the conduct of the study.
14. Known positive for hepatitis B antigen, or hepatitis C virus antibody, or for human immunodeficiency virus (HIV) or a diagnosis of acquired immunodeficiency syndrome.
15. Clinically diagnosed significant anxiety disorder, or any other significant psychiatric disorder (e.g. depression) that might interfere with the participant's participation in the study
16. An inability to substantially lessen GL and/or horizontal forehead rhytids even by physically spreading them apart as determined by the investigator.
17. Known allergy or hypersensitivity to BoNT or any excipients of IPN10200 or Dusport/Azzalure, or allergy to cow's milk protein.
18. A history of drug or alcohol abuse
19. Pregnant women, nursing women, premenopausal women or women of childbearing potential not willing to practice a highly effective form of contraception method
20. Male participants who are not vasectomized and who have female partners of childbearing potential and are not willing to use condoms with spermicide throughout study participation.
