Safety of Cell-free Adipose Tissue Product in Healthy Volunteers (SAFETY)

January 26, 2026 updated by: Linio Biotech Oy

Evaluating the Safety and Tolerability of the Liponovo Tissue Product in Healthy Volunteers

The study is a randomized, double blinded, bilaterally controlled trial.The aim is to evaluate the short- and mid term safety of cell-free adipose tissue product. The safety of the tissue product is to be studied in 40 healthy volunteers. Cell-free tissue product is injected into superficial part of the subcutis with one injection to standardized area. The volume of the injection is 4,5 ml. As the control method, the same size area is injected with plain Ringer-Acetat solution. The adverse events and serious adverse events are monitored in doctor visits, phone calls and e-diary.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Liponovo tissue product and Ringer Acetat injections
Investigational products (Liponovo tissue product and Ringer Acetat) are injected into the dorsal forearm, superficial part of the subcutis.
Other: Liponovo tissue product
Investigational products (Liponovo tissue product and Ringer Acetat) are injected into the dorsal forearm, superficial part of the subcutis. The single injection and a 23G/30mm needle are used. The amount of the injected investiogational products is 4,5 ml for both dorsal forearms (together 4,5ml x2 = 9ml / test subject). The product is always injected in the proximal third of the forearm, into a standardized a quarter circle with a radius of 30mm. Both injections are performed with covered syringe to ensure the double-blinding. After the injection, test subjects get a cold on the injection sites to reduce the bruising.
