A Study in Adults Evaluating Polycaprolactone Microsphere Filler for Treatment of Moderate to Severe Nasolabial Folds
208 participantsStarted 2025-05-01
Plain-language summary
The goal of this clinical trial is to evaluate the safety and efficacy of polycaprolactone microsphere filler (Lafullen) for the correction of moderate to severe nasolabial folds in adults aged 18 and above, regardless of gender.
The main questions it aims to answer are:
* Does Lafullen improve wrinkle severity in the nasolabial fold area at 48 weeks post-injection (WSRS responder rate)?
* Is Lafullen superior to the control product (Restylane, a hyaluronic acid filler) in terms of long-term wrinkle correction and safety? Researchers will compare Lafullen (polycaprolactone filler) with Restylane (modified sodium hyaluronate gel) to see if Lafullen provides superior wrinkle correction at 12 months post-injection.
Participants will:
* Receive either Lafullen or Restylane via injection in the nasolabial fold area.
* Optionally receive a touch-up injection at 4 weeks after the first treatment if needed.
* Undergo regular follow-up visits at 4, 12, 24, 36, and 48 weeks post-treatment.
* Subjects in the Lafullen group will continue follow-up up to 72 weeks to assess long-term efficacy and safety.
* Be assessed through clinical photography, pain scale (VAS), satisfaction questionnaires, and safety evaluations (e.g., AEs, vital signs, lab tests).

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. Previous surgery, cosmetic facial procedure, or plans to undergo cosmetic surgery in NLF area or lower face during the trial, inculding any of the following circumstances:
. Received permanent fillers or prostheses (such as PMMA etc.) or semi-permanent dermal fillers (such as CaHA, PLLA, PCL, etc.).
. Received temporary dermal fillers (such as HA and collagen etc.) within 12 months prior to screening.
. Received anti-wrinkle surgery within 12 months prior to screening.
. Receiving botulinum toxin injection, chemical stripping, radiofrequency laser, and liquid nitrogen freezing anti-wrinkle treatment within 6 months.
. Individuals who used topical agents (e.g., corticosteroids, steroids \[excluding hydrocortisone\], retinoids, or retinoid derivatives intended as medications but not as cosmetics) on the mid-to-lower facial area within 3 months prior to screening or plan to use them during the trial period, as well as those undergoing hydrocortisone treatment.
. Individuals with abnormal coagulation mechanisms \[activated partial thromboplastin time (APTT) \>1.5 times the upper limit of normal (ULN), etc.\], or use of anticoagulants (e.g., warfarin, rivaroxaban), antiplatelet agents (e.g., aspirin, clopidogrel), thrombolytic agents (e.g., recombinant human urokinase) within 2 weeks prior to screening.
