About this study
Official title: A Randomized, Double-Blind, Placebo-Controlled, Phase 2 Study to Evaluate the Efficacy, Safety, Tolerability, and Pharmacokinetics of ASN002 in Subjects With Moderate To Severe Chronic Hand Eczema Refractory to Corticosteroid Therapy
Randomized double-blind/placebo study to evaluate the efficacy of ASN002 in subjects with severe chronic hand eczema.
Read the detailed description
This is a placebo controlled study where subjects with severe chronic hand eczema will be randomized (1:1:1) to receive ASN002 at 40 mg, 80 mg, or placebo once daily for 16 weeks (Part A). Then, in Part B, subjects who were assigned to placebo in the first part of the study will receive the highest dose of ASN002 (80 mg) for the rest of the treatment period (up to Week 32). The subjects who were assigned ASN002 in the first part of the study will continue on the same assigned treatment dose during the second part of the study (Week 16 to Week 32). The total treatment period of 32 weeks will be followed by a 4 week follow-up period.This study will also characterize the pharmacokinetics and pharmacodynamics of ASN002 through blood sampling and three or four biopsies from subjects who consent.

ASN002Drug
Daily dose of ASN002 for 32 weeks
Placebo Oral TabletDrug
Daily dose of Placebo Oral Tablet for 16 weeks
| Study group | Role | What they receive |
|---|---|---|
| ASN002 40 mg | Experimental | 40 mg ASN002 Receives: Drug: ASN002 |
| ASN002 80 mg | Experimental | 80 mg ASN002 Receives: Drug: ASN002 |

What is being measured
The primary outcome is the main question the study is designed to answer.
Percent Change From Baseline in Modified Total Lesion Symptom Score (mTLSS)
Percent change from baseline in hand mTLSS at Week 16. The mTLSS is an assessment of the severity of each of the following: erythema, scaling, lichenification/hyperkeratosis, vesicles, edema, fissures, and pruritus/pain. Each of these are rated using a 4-point severity scale. The ratings are added to create a total mTLSS calculated as the sum of assigned individual scores with a maximum value of 21 (most severe disease) and a minimum of 0 (no disease)
Measured: 16 weeks
Secondary outcomes (2)
Change From Baseline in Hand Physician Global Assessment (PGA)
Proportion of participants with a response of Physicians Global Assessment achieving clear (0) or almost clear (1)
Measured: 16 weeks
Change From Baseline in Hand Patient Global Assessment (PaGA)
Reduction of PaGA compared to baseline where marked improvement was noted with at least 75% clear
Measured: 16 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing ASN002 in people with Chronic Hand Dermatitis, run by Asana BioSciences at 23 sites in 2 countries.
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 9 inclusion and 8 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: finished, as of the sponsor's last update on 9 May 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 23 sites in United States, Canada. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 9 May 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percent Change From Baseline in Modified Total Lesion Symptom Score (mTLSS) (time frame: 16 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03728504, which also lists 1 linked publication.
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 9 May 2023; AzTrials last refreshed its copy on 6 Nov 2026.
