1. Has a history of hypersensitivity or allergy to collagenase or any other excipients of CCH.

2. At the Screening Visit has a CR-PCSS score of less than 2 or greater than 3 for the area to be treated (buttocks or thighs) and/or has a Hexsel CSS Subsection D "Grade of Laxity, Flaccidity, or Sagging Skin" score of less than 2 or greater than 3 (severe) for the areas to be treated (buttocks or thighs).

3. Has a coagulation disorder which requires anticoagulant or antiplatelet medication during the study (except for ≤ 150 mg aspirin daily), or has taken anticoagulant or antiplatelet medication(s) within 14 days before injection of study treatment (except for ≤ 150 mg aspirin daily).

6. Is pregnant and/or is breast-feeding or plans to become pregnant and/or to breast-feed during the course of the study.

7. Has a history of scarring due to keloids or abnormal wound healing.

8. Has local (in areas to be treated) conditions (thrombosis, vascular disorder, active infection/inflammation, active cutaneous alteration, tattoo/mole) that restricts study participation

9. Has history of drug or alcohol abuse within the 5 years prior to the Screening Visit.

10. Has evidence of clinically significant abnormalities, as judged by the investigator, in any of the following: physical examination findings, electrocardiogram (ECG), clinical laboratory values, or vital signs.

The sponsor's medical monitor will be required to review the results for confirmation of eligibility in the case of any of the following: abnormalities in ECGs indicating corrected QT interval (QTc) prolongation of 470 ms or greater; and clinical laboratory values of liver enzymes

11. Has used or intends to use any of the local application/therapies/injections/procedures that restricts study participation.

12. Has any other condition(s) that, in the investigator's opinion, might indicate the participant to be unsuitable for the study.
