Safety and Effectiveness of GP0112 for Cheek Augmentation and Correction of Midface Contour Deficiencies

Exclusion Criteria

• •1. Known/previous allergy or hypersensitivity to any injectable hyaluronic acid (HA) gel or to gram positive bacterial proteins.
• •2. Known/previous allergy or hypersensitivity to local anesthetics, e.g. lidocaine or other amide-type anesthetics or nerve blocking agents (if intended to be used for that subject).
• •3. Previous or present severe or multiple allergies manifested by severe reactions, such as anaphylaxis or angioedema, or family history of these conditions.
• •4. Previous facial surgery (e.g. facial fat removal, facelift and sinus surgery) in or near the treatment area that in the Treating Investigator´s opinion could interfere with the study safety and/or effectiveness assessments.
• •5. Any previous aesthetic procedures or implants:
• •* Previous use of any permanent (non-biodegradable) or semi-permanent (e.g., calcium hydroxylapatite or Poly-L-Lactic acid) facial tissue augmentation therapy, lifting threads, permanent implants or autologous fat in the face regardless of time.
• •* Previous HA filler or collagen filler in or near the treatment area within 12 months.
• •* Previous botulinum toxin treatment in or near the treatment area within 6 months.
• •* Previous energy based aesthetic procedures (e.g. laser, intense pulsed light, radiofrequency and ultrasound) in or near the treatment area within 6 months.
• •* Previous mechanical (e.g. dermabrasion, needling) or chemical aesthetic procedures (e.g. chemical peel) in or near the treatment area within 6 months.
• •* Previous treatment with cryotherapy in or near the treatment area within 6 months.
• •6. History of cancer or previous radiation near or on the area to be treated.
• •7. Presence of any disease or lesions near or on the area to be treated, e.g.,
• •* Inflammation, active or chronic infection (e.g., in mouth, dentals, head);
• •* Facial psoriasis, eczema, acne, rosacea, perioral dermatitis, herpes simplex or herpes zoster;
• •* Scars or deformities;
• •* Cancer, or precancerous conditions (e.g. actinic keratosis or actinic cheilitis).
• •8. Evidence of scar-related disease or delayed healing activity within 1 year prior to the baseline visit, or subjects susceptible to keloid formation, hyperpigmentation or hypertrophic scarring.
• •9. Presence of tattoo, piercing, beard or facial hair, which, in the Treating Investigator's opinion, would interfere with the study injections and/or study assessment.
• •10. Presence of a dental, oral, or facial condition which, in the Treating Investigator's opinion, would interfere with the study injections and/or study assessment; e.g. has dentures or any device covering all or part of the upper palate, and/or severe malocclusion or dentofacial or maxillofacial deformities. Any planned procedure (e.g. dental implants, tooth extractions, orthodontia) during the study period, that would make the subject unsuitable for inclusion in the opinion of the Investigator.
• •11. An underlying known disease, a surgical or medical condition that would expose the subject to undue risk, e.g. human immunodeficiency virus (HIV), active hepatitis, autoimmune disease, history of bleeding disorders, connective tissue diseases such as rheumatoid arthritis, systemic lupus erythematosus, polymyositis, dermatomyositis, or scleroderma.
• •12. Use of concomitant medication that have the potential to prolong bleeding times such as anticoagulants or inhibitors of platelet aggregation (e.g. aspirin or other non-steroidal anti-inflammatory drugs (NSAIDs), Omega 3 or Vitamin E), within 14 days prior to injection. Omega 3 and Vitamin E are acceptable only as part of a standard multivitamin formulation.
• •13. Treatment with chemotherapy, immunosuppressive agents, immunomodulatory therapy (e.g. immunosuppressive monoclonal antibodies, antiviral treatment for HIV or hepatitis).
• •14. Treatment with systemic corticosteroids (inhaled corticosteroids are allowed) within 3 months prior to Baseline visit.
• •15. Use of topical facial corticosteroids or prescription retinoids near or on the area to be treated within 1 month of the Baseline visit or systemic retinoid treatment within 6 months of the Baseline visit, or plan to receive such treatment during participation in the study.
• •16. Presence of any condition or situation, which in the opinion of the Treating Investigator makes the subject unable to complete the study per protocol, e.g.
• •* Subject is not likely to avoid other prohibited facial cosmetic treatments;
• •* Subject is not likely to complete the study because of other commitments;
• •* Subject is anticipated to be unavailable for visits, incapable of understanding the investigational assessments or having unrealistic expectations of treatment result;
• •* Subject who has a concomitant condition (e.g. acute viral or bacterial infection with fever) that might confuse or confound study treatments or assessments.
• •17. Subject who plan to lose or has a medical condition that may cause them to lose a significant amount of weight during the course of the study.
• •18. Study center personnel, close relatives of the study center personnel (e.g. parents, children, siblings, or spouse), employees or close relatives of employees at the Sponsor company.
• •19. Participation in any other interventional clinical study within 30 days before treatment.
