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

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

| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Consistency of the Treated Nodules at Day 57 | Baseline, 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. |
| Percent Change From Baseline in Hardness of the Treated Nodule at Day 57 | Baseline, 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. |
| Change From Baseline in Nodular Pain of the Treated Nodule at Day 57 | Baseline, 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. |
| Percent Change From Baseline in Surface Area and Volume of the Treated Nodule at Day 57 Using Ultrasound | Baseline, Day 57 | 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. |
| Subject Satisfaction With Treatment | Day 57 | 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. |
| Composite Responder Analysis | Day 57 | 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. |
| Investigator Global Assessment of Improvement With Treatment | Day 57 | 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. |

Outcome results
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.
