Brief Summary

The Stage 2 of this phase 2 study is an open-label, single-arm study to assess the efficacy and safety of CBL-514 in participants with Edematous Fibrosclerotic Panniculopathy (EFP) cellulite.

Conditions

Cellulite

Outcome Measures

Primary Outcomes (1)

• Evaluation of the Score Change of Edematous Fibrosclerotic Panniculopathy (EFP) Measured by Cellulite Severity Scale From Baseline Following Administration of at Least 1 Course of CBL-514.

  Change in total scores from baseline in the Modified Hexsel Cellulite Severity Scale to 4 weeks after the final treatment. The Modified Hexsel Cellulite Severity Scale is based on (A) number of evident depressions, (B) depression depth scale, and (C) morphological appearance of skin surface alterations.

  From baseline to 4 weeks after the final treatment visit

Secondary Outcomes (5)

• Percentage of Participants' Thighs That Achieve at Least 1-level Severity Improvement Measured by Cellulite Severity Scale From Baseline Following Administration of at Least 1 Course of CBL-514.

  From baseline to 4 weeks after the final treatment visit

• Evaluation of the Total Score Change of Edematous Fibrosclerotic Panniculopathy (EFP) Measured by Cellulite Severity Scale From Baseline Following Administration of at Least 1 Course of CBL-514.

  From baseline to 12 weeks after the final treatment visit

• Percentage of Participants' Thighs That Achieve at Least 2-score Improvement Measured by Cellulite Severity Scale From Baseline Following Administration of at Least 1 Course of CBL-514.

  From baseline to 4 weeks after the final treatment visit

• Percentage of Participants' Thighs With Improvement in Global Aesthetic Improvement Scale (GAIS) Reported by the Clinician, Following the Administration of at Least 1 Course of CBL-514.

  4 weeks after the final treatment visit

• Percentage of Participants' Thighs With Improvement in Global Aesthetic Improvement Scale (GAIS) Reported by the Participant, Following the Administration of at Least 1 Course of CBL-514.

  4 weeks after the final treatment visit

Other Outcomes (4)

• Number of Participants With Treatment-emergent Adverse Events (TEAEs)

  From baseline until the end of follow-up, up to 17 weeks

• Number of Treatment-emergent Adverse Events (TEAEs)

  From baseline until the end of follow-up, up to 17 weeks

• Number of Participants With Adverse Events of Special Interest

  From baseline until the end of follow-up, up to 17 weeks

Study Arms (1)

CBL-514 up to 320mg

EXPERIMENTAL

Drug: CBL-514 injection

Interventions

CBL-514 will be administered at the raised area of cellulite.

CBL-514 up to 320mg

Eligibility Criteria

• Age: 18 Years - 64 Years
• Sex: female
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• Female aged 18 years to 64 years old (at Screening), inclusive.
• Have a BMI \> 18.5 and \< 35 kg/m2 and body weight ≥ 50 kg at Screening and Day 1.
• The participant has both sides of posterolateral thighs assessed according to the modified Hexsel CSS (A) number of evident depressions, (B) depression depth scale, and (C) morphological appearance of skin surface alterations. On assessment by the modified Hexsel CSS, the participant scores at least 4 and no greater than 8 at Screening and Day 1.
• The total score must contain:
• Hexsel CSS item (A) 'number of evident depressions' score of ≥1
• Hexsel CSS item (B) 'depth of depressions' score of ≥ 1
• Participant has a stable lifestyle (e.g., exercise, eating patterns, and smoking habit) per participant report for at least 3 months before Screening and during the study.
• Voluntarily signs the informed consent form and, in the opinion of the Investigator or delegate, is physically and mentally capable of participating in the study, and willing to adhere to study procedures.

You may not qualify if:

• Female participant of childbearing potential who is not willing to commit to an acceptable contraceptive regimen with her partner from the time of Screening and throughout study participation until 90 days after the last IP dose, or who is currently pregnant or lactating. Note: females who are not of childbearing potential are not required to use contraception. Females not of childbearing potential are defined as those who have been surgically sterilized (hysterectomy or bilateral oophorectomy) or who are postmenopausal (defined as aged at least 50 years old with ≥ 12 months of amenorrhea and a follicle-stimulating hormone \[FSH\] \> 30 IU/L at Screening).
• Participant diagnosed with coagulation disorders or is receiving anticoagulant/antiplatelet therapy or medications or dietary supplements, which impede coagulation or platelet aggregation within 14 days prior to the IP administration.
• Participant has hemoglobin A1c (HbA1c) ≥ 9%, delayed wound healing, or any diabetic risks which, in the opinion of the Investigator (or designee) is inappropriate to participate in the study.
• Participant has a clinically significant cardiovascular disease and abnormal findings in electrocardiogram (ECG) at Investigator's (or designee's) discretion.
• Participant with active or prior history of malignancies within 5 years before Screening or being assessed for a possible malignancy. Except adequately treated basal cell carcinoma of the skin and in situ squamous cell carcinoma of the skin would be eligible as per Investigator's (or designee's) discretion.
• Participant with a history of human immunodeficiency virus (HIV)-1 infection, or participants with active HIV infection at Screening with a positive HIV antigen/antibody (Ag/Ab) combination test.
• Participant with a history of trypanophobia, the extreme fear of medical procedures involving injections or needles, or who experience vasovagal syncope and pass out at the sight of blood or a needle.
• Participant with any hepatic medical condition that, in the opinion of the Investigator (or designee), would interfere with assessment of safety or efficacy or compromise the participant's ability to undergo study procedures or provide informed consent.
• Participant who has a recent history of major depression, anxiety, or other psychiatric disease requiring treatment with prescription medication within 6 months prior to Screening.
• Participant has abnormal skin or local skin conditions at the treatment area, which in the opinion of the Investigator (or designee), is inappropriate to participate in the study. This includes but is not limited to any of the following:
• skin manifestations of a systemic disease
• any abnormality of the skin or soft tissues on the anticipated treatment area
• skin laxity on treatment area when the participant is in the standing position
• sensory loss or dysesthesia in the area to be treated
• evidence of any cause of enlargement in the area to be treated other than localized subcutaneous fat
