About this study
Official title: A Safety, Efficacy and Pharmacokinetic Evaluation Study of Intralesional Ronkyla Plus Injection for the Treatment of Superficial Lipoma
This study aims to evaluate the safety, efficacy, and pharmacokinetics of Ronkyla Plus, a combinational drug that forms a hydrogel at the injection site, promising a better experience of lipolysis injection for the treatment of superficial lipoma. The study consists of a Part I dose-escalation study to investigate the drug's maximum tolerated dose (MTD) for this indication and a Part II study for evaluating its relative bioavailability in comparison to an FDA-approved lipolysis injection, Kybella.
Read the detailed description
Part I is a randomized, double-blind, placebo-controlled, and sequential dose-escalation study. Eligible subjects will receive intralesional injections of Ronkyla Plus or placebo at a volume dependent on the size of their superficial lipoma, up to a maximum of 10 mL per treatment, at 28-day intervals for up to a maximum of 6 treatments. In the first treatment cycle, subjects will stay in hospital for 3 hours after treatment for evaluation of acute safety profile. Subjects will return to the hospital on Day 8 and Day 29 of each treatment cycle for safety profile evaluation.
Part II is an open-label, single-dose, 2-treatment, parallel study to evaluate the relative bioavailability of Ronkyla Plus injection in comparison with that of Kybella injection. Eligible, non-smoking males and females aged 18 to 65 with treatable superficial lipoma or submental fullness will be included in the study. Twenty (20) subjects for each target symptom, in a total of 40 subjects, are planned to be enrolled in the study to achieve at least 16 evaluable subjects in each treatment group. After screening, subjects will be assigned to Ronkyla Plus or Kybella treatment based on their symptoms and undergo a 16-day PK assessment.
For Ronkyla Plus injection, subject will receive a single intralesional treatment at the maximum tolerated dose (MTD) as determined in Part I. For Kybella injection, subject will receive the maximum dose approved for a single treatment (100 mg) in the submental area.
In the PK assessment period, subjects will visit the hospital in the mornings of Day 3 (48.0 h), Day 5 (96.0 h), Day 8 (168.0 h), Day 11 (240.0 h), and Day 15 (336.0 h), and two consecutive 24-hr PK blood samplings from Day -2 evening to Day 2 morning (pre-dose, 0.25, 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0, 12.0, 16.0, 24.0 h post-dose on Day 1~Day 2; same blood sampling time on Day -1~Day 1 without dosing). Two weeks after the end of the 16-day PK assessment period, subjects of Ronkyla Plus cohort will be eligible for up to 5 additional treatments of Ronkyla Plus for complete clearance of their target superficial lipomas, whereas subjects of Kybella cohort will be eligible for up to 5 additional treatments of Ronkyla (10.56 mg/mL SDC injection approved in Taiwan for submental fullness treatment, pharmaceutical equivalent of Kybella) for improvement of their submental fullness.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study aims to evaluate the safety, efficacy, and pharmacokinetics of Ronkyla Plus, a combinational drug that forms a hydrogel at the injection site, promising a better experience of lipolysis injection for the treatment of superficial lipoma. The study consists of a Part I dose-escalation study to investigate the drug's maximum tolerated dose (MTD) for this indication and a Part II study for evaluating its relative bioavailability in comparison to an FDA-approved lipolysis injection, Kybella.
Detailed description
Part I is a randomized, double-blind, placebo-controlled, and sequential dose-escalation study. Eligible subjects will receive intralesional injections of Ronkyla Plus or placebo at a volume dependent on the size of their superficial lipoma, up to a maximum of 10 mL per treatment, at 28-day intervals for up to a maximum of 6 treatments. In the first treatment cycle, subjects will stay in hospital for 3 hours after treatment for evaluation of acute safety profile. Subjects will return to the hospital on Day 8 and Day 29 of each treatment cycle for safety profile evaluation.
Part II is an open-label, single-dose, 2-treatment, parallel study to evaluate the relative bioavailability of Ronkyla Plus injection in comparison with that of Kybella injection. Eligible, non-smoking males and females aged 18 to 65 with treatable superficial lipoma or submental fullness will be included in the study. Twenty (20) subjects for each target symptom, in a total of 40 subjects, are planned to be enrolled in the study to achieve at least 16 evaluable subjects in each treatment group. After screening, subjects will be assigned to Ronkyla Plus or Kybella treatment based on their symptoms and undergo a 16-day PK assessment.
For Ronkyla Plus injection, subject will receive a single intralesional treatment at the maximum tolerated dose (MTD) as determined in Part I. For Kybella injection, subject will receive the maximum dose approved for a single treatment (100 mg) in the submental area.
In the PK assessment period, subjects will visit the hospital in the mornings of Day 3 (48.0 h), Day 5 (96.0 h), Day 8 (168.0 h), Day 11 (240.0 h), and Day 15 (336.0 h), and two consecutive 24-hr PK blood samplings from Day -2 evening to Day 2 morning (pre-dose, 0.25, 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0, 12.0, 16.0, 24.0 h post-dose on Day 1~Day 2; same blood sampling time on Day -1~Day 1 without dosing). Two weeks after the end of the 16-day PK assessment period, subjects of Ronkyla Plus cohort will be eligible for up to 5 additional treatments of Ronkyla Plus for complete clearance of their target superficial lipomas, whereas subjects of Kybella cohort will be eligible for up to 5 additional treatments of Ronkyla (10.56 mg/mL SDC injection approved in Taiwan for submental fullness treatment, pharmaceutical equivalent of Kybella) for improvement of their submental fullness.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Ronkyla Plus and Kybella in people with Lipoma and Submental Fullness, run by Glonova Pharma Co., Ltd at 3 sites in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 21 inclusion and 29 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 2 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Cindy Chen, MS ((+886) 2-2351-1190 ext. 233, Cindy.Chen@glonova.com.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Part I: Incidence of all adverse events (time frame: 7 months (Part I); 1 month (Part II)). The study lists 23 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Oct 2026.
