An interventional study of BtH Body 2.2% in Aesthetic Body Volume Loss, sponsored by i+Med S.Coop.. Recruiting at 1 site in Spain. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-07-09.
Sponsored by i+Med S.Coop. · Not applicable, Interventional, and Treatment
This clinical investigation is a prospective, interventional, single-center study designed to assess the safety and effectiveness of BtH Body 2.2%, a cross-linked hyaluronic acid injectable intended for aesthetic volumization and contouring of large body areas. The study enrolls 80 adult participants who seek aesthetic improvement in the gluteal region, thighs, or abdomen. Each participant will receive a single session of subcutaneous injections, with the option for a touch-up treatment at four weeks if clinically justified, and will be followed for a total of nine months.
The primary aim of the study is to determine whether BtH Body 2.2% produces a clinically relevant improvement in the treated area, assessed by the Global Aesthetic Improvement Scale (GAIS), and to evaluate the safety profile of the product by monitoring the incidence of serious adverse events throughout the study period. Secondary assessments will examine patient satisfaction, investigator-rated changes in aesthetic parameters such as volume, firmness, uniformity, elasticity, and overall appearance, as well as improvements in quality of life using validated questionnaires, including the Body Self-Esteem Scale and the Patient Global Impression of Improvement (PGI-I). Objective measurements of skin hydration, elasticity, firmness, and topography will also be obtained using specialized biometric devices.
The overall goal is to generate robust clinical evidence supporting the use of BtH Body 2.2% for safe and effective body contouring and volumization.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
