Overview
Brief Summary
This is a randomized, double-blind, placebo-controlled Phase Ⅱ clinical study to evaluate the efficacy, safety, and immunogenicity of CU-20401 for Injection in a population with moderate to severe contour elevation or over-fullness due to SMF accumulation.
Detailed Description
Eligible subjects were randomized in a 1: 1: 1 ratio to CU-20401 low dose group (0.06 mg/dose), CU-20401 high dose group (0.08 mg/dose), or placebo group using the severity of baseline clinician-reported SMF accumulation (score 2 or 3) as a stratification factor, and received a single subcutaneous injection of this group in the submental fat region on D1; return to the hospital for efficacy assessment on D29, D57, D85 or at early withdrawal; return to the hospital for safety assessment on D1, D8, D15, D29, D57, D85 or early withdrawal; immunogenicity samples were collected on D1, D8, D15, D29, D57, D85, or at early withdrawal (the study design is shown in the figure below).
Investigators
Eligibility Criteria
Inclusion Criteria
- •Fully understand the study contents, study process and possible adverse reactions, be able to complete the study in accordance with the protocol requirements, have reasonable expectations for the injection effect, and voluntarily sign the informed consent form;
- •Men or women aged 18 to 65 years (including boundary values) at the time of signing the ICF;
- •Body mass index (BMI) between 17 and 40 (kg/m2) at screening and baseline (including cut-off);
- •At screening and baseline, the investigator rated moderate to severe submental outline protrusion due to submental fat accumulation according to the clinician-reported Submental Fat Rating Scale (CR-SMFRS) , i.e., those with a score of 2 to 3 points; and the subject-reported Submental Fat Rating Scale (PR-SMFRS)rated the amount of submental fat as moderate/large/very large, i.e., those with a score of 2 to 4;
- •Subjects of childbearing potential (including males and females) have no pregnancy plans and voluntarily take effective contraceptive measures at screening and throughout the trial, and have no sperm or egg donation plans.
Exclusion Criteria
- •Subjects who have received prior surgery, liposuction therapy, or injection of lipolytic drugs similar to the investigational drug (e.g., phosphatidylcholine, etc.) at the submental site;
- •Those who have received biomaterial fillings (e.g., hyaluronic acid, collagen, etc.) within 24 months prior to screening and at the neck or submental site before baseline;
- •Those who have received botulinum toxin injection within 3 months prior to screening and at the neck or submental site prior to baseline, or have received noninvasive skin tightening therapy;
- •Planned to undergo cosmetic procedures at the submental site during the study, including, but not limited to, dermal filling, surgical wrinkle removal, photoelectric therapy, water light needles, microneedles, chemical exfoliation, or scar removal surgery, etc.;
- •Enlargement of the submental area due to other causes of excess non-submental fat accumulation (e.g., goiter, lymphadenopathy, Madelong's disease, platysma protrusion at rest, etc.) or affect the investigator's assessment of submental fat;
- •Those with obvious scars, infections, cancerous or precancerous lesions and/or unresolved wounds, retrognathia, etc. in the chin and neck position, which may affect the evaluation results as assessed by the investigator;
- •According to the investigator's judgment, submental fat dissolution can cause submental skin relaxation (SMSLG) to be Grade 4 or have other anatomic features (e.g., bulging fat under the platysma, extreme skin relaxation of the neck or submental area, protrusion of the platysma band), resulting in unacceptable cosmetic results;
- •Subjects with a pre-existing tendency to scar hyperplasia or keloid may affect the efficacy assessment or subject safety after treatment as judged by the investigator;
- •Subjects with symptoms or associated diseases of dysphagia at screening and baseline;
- •Abnormal clinical laboratory tests (AST or ALT values above twice the upper limit of normal; serum creatinine above 1.5 times the upper limit of normal; triglycerides above 2 times the upper limit of normal) at screening and baseline; or other laboratory tests, vital signs, physical examination, electrocardiogram test results are abnormal and clinically significant, and the investigator considers it inappropriate to participate in this study;
Arms & Interventions
Low Dose Group
0.06mg/ml/dose, the number of doses administered (no more than 36 doses) will be determined after the area has been assessed by the investigator based on the subject's submental fat accumulation
Intervention: Subcutaneous injection of CU-20401
High Dose Group
0.08 /ml/dose, the number of doses administered (no more than 36 doses) will be determined after the area has been assessed by the investigator based on the subject's submental fat accumulation
Intervention: Subcutaneous injection of CU-20401
Placebo group
0/ml/dose, the number of doses administered (no more than 36 doses) will be determined after the area has been assessed by the investigator based on the subject's submental fat accumulation
Intervention: Subcutaneous injection of CU-20401
