About this study

Official title: A Phase 2a, Double-blind, Randomized, Placebo-Controlled, Dose-Ranging Study to Evaluate the Safety and Effectiveness of AA4500 in the Treatment of Dupuytren's Disease Nodules

The objectives of this study are to assess the safety and effectiveness of AA4500 in treating palmar Dupuytren's disease nodules.

Read the detailed description

Approximately 13 sites in the United States and Australia, approximately 90 study subjects.

After all pre-injection procedures are completed on day 1, eligible men and women will be randomized in a 1:1:1 ratio to dose group and then in a 4:1 ratio to treatment group. Study drug will be administered into a palmar nodule located on the selected hand.

AA4500 (collagenase clostridium histolyticum) 3 doses (low, medium, and high) after reconstitution with sterile diluent (0.3 mg/mL calcium chloride dihydrate in 0.9% sodium chloride). Each dose of study drug will be injected into the nodule. The injection will be administered in 3 different volumes according to randomization.

Placebo after reconstitution with sterile diluent (0.3 mg/mL calcium chloride dihydrate in 0.9% sodium chloride). Each dose of study drug will be injected into the nodule. The injection will be administered in 3 different volumes according to randomization.

Follow up visits for the evaluation of safety and efficacy will be required for all subjects on days 8, 29, and 57.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent Change From Baseline in Surface Area and Volume of the Treated Nodule at Day 57 Using Caliper Measurements

    Percent change from baseline in surface area and volume of the treated nodule was determined from hand-held caliper measurements of the length and width of the nodule. Percent change = 100*(Day 57 area [or volume] - baseline area [or volume])/baseline area [or volume]. A negative value represents the improvement from baseline (decreased size) while a positive value represents worsening.

    Measured: Baseline, Day 57

Secondary outcomes (7)
  1. Percent Change From Baseline in Surface Area and Volume of the Treated Nodule at Day 57 Using Ultrasound

    Percent change from baseline in surface area and volume of the treated nodule was determined from ultrasound measurements of the length, width, and depth of the nodule. Percent change = 100*(Day 57 area [or volume] - baseline area [or volume])/baseline area [or volume]. A negative value represents the improvement from baseline (decreased size) while a positive value represents worsening.

    Measured: Baseline, Day 57

  2. Change From Baseline in Consistency of the Treated Nodules at Day 57

    Investigators determined the consistency of the nodule through palpitation using a 5-point scale: 5 = hard (solid), 4 = firm throughout, 3 = moderate firmness, 2 = soft, and 1 = non-palpable. The change scores could range from +4 (greatest worsening in consistency) to -4 (greatest improvement in consistency); a negative change from baseline value reflects improvement from baseline (softening) while a positive value reflects worsening.

    Measured: Baseline, Day 57

  3. Percent Change From Baseline in Hardness of the Treated Nodule at Day 57

    A durometer was used to assess nodule hardness on a scale of 0 (soft) to 100 (hard). Percent change = 100*(Day 57 hardness - baseline hardness)/baseline hardness. A negative value represents the improvement from baseline (softening) while a positive value represents worsening.

    Measured: Baseline, Day 57

  4. Change From Baseline in Nodular Pain of the Treated Nodule at Day 57

    After the nodule was squeezed using a dynamometer, subjects were asked to rate the amount of pain they felt on an 11-point visual analog scale (VAS) from 0 (no pain or discomfort) to 10 (extreme pain or discomfort). A negative change from baseline value reflects improvement from baseline (less pain) while a positive value reflects worsening.

    Measured: Baseline, Day 57

  5. Investigator Global Assessment of Improvement With Treatment

    Investigators were asked to determine the degree of improvement in the subject's treated nodule compared with screening on a 7-point scale: 1 = very much improved, 2 = much improved, 3 = minimally improved, 4 = no change, 5 = minimally worse, 6 = much worse, and 7 = very much worse.

    Measured: Day 57

  6. Subject Satisfaction With Treatment

    Subjects were asked to rate their satisfaction with treatment on a 5-point scale: 1 = very satisfied, 2 = quite satisfied, 3 = neither satisfied nor dissatisfied, 4 = quite dissatisfied, and 5 = very dissatisfied.

    Measured: Day 57

  7. Composite Responder Analysis

    A composite responder is a subject who had an improved assessment [values of 1 (very much improved), 2 (much improved), or 3 (minimally improved)] on the investigator global assessment and had a satisfied assessment [values of 1 (very satisfied) or 2 (quite satisfied)] on the subject assessment.

    Measured: Day 57

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Collagenase clostridium histolyticum in people with Dupuytren's Disease, run by Endo USA Inc., a Keenova Therapeutics Company at 11 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 8 inclusion and 11 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 5 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in United States, Australia. 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 7 Jul 2015). 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 Surface Area and Volume of the Treated Nodule at Day 57 Using Caliper Measurements (time frame: Baseline, Day 57). 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 NCT02193828, 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 5 Oct 2017.
