The resistance encountered to passive stretch was graded using a 6-point scale where: 0=no increase in muscle tone (best) to 4=affected part(s) rigid in flexion or extension (worst). For analysis purposes, the MAS-B was recoded as follows: 0=1, 1=1, 1+=2, 2=3, 3=4, 4=5. The scores at Weeks 4 and 6 were averaged. A Mixed Model Repeated Measures (MMRM) model was used for analysis.

An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not related to the medicinal product. A TEAE is an AE that occurs or worsens after receiving study drug.

A negative change from Baseline (decrease in volume) indicates improvement.

Change From Baseline in the Total International Prostate Symptom Score (IPSS) at Week 12
Baseline, Week 12

IPSS is a disease-specific outcome measure based on the American Urological Association Symptom Index. The questionnaire consisted of seven items. The patient evaluated their urinary symptoms (incomplete emptying, frequency, hesitancy, urgency, weak stream, straining, and nocturia) during the previous 4 weeks.

Frequently asked questions about botulinum toxin Type A

What is botulinum toxin Type A?

Botulinum toxin Type A is an investigational biologic that AbbVie Inc. (ticker ABBV) is developing across several therapeutic areas. It is being studied in urology for benign prostatic hyperplasia and in other indications including cervical dystonia, hyperhidrosis, lateral canthal lines, lateral canthus rhytides, and masseter muscle hypertrophy. It remains in clinical development.

What does botulinum toxin Type A target?

Botulinum toxin Type A targets SNAP25, a hydrolytic enzyme. By acting on this target, the drug is designed to interfere with the SNAP25-mediated process. This mechanism underlies its study across the various indications in AbbVie's development program.

Who makes botulinum toxin Type A?

AbbVie Inc., which trades under the ticker ABBV, is the developer of botulinum toxin Type A. The company is running the clinical program for this asset across its studied indications, including benign prostatic hyperplasia, cervical dystonia, hyperhidrosis, and facial line conditions.

What phase is botulinum toxin Type A in?

Botulinum toxin Type A is in Phase 2 development. It is investigational and has not been approved. The program includes four completed clinical trials with a total enrollment of 1,833 participants, and the studies were randomized, double-blind, and placebo-controlled.

What clinical trials is botulinum toxin Type A in?

Four completed trials have studied botulinum toxin Type A: NCT04073303 in masseter muscle prominence, NCT02195687 in Crow's feet lines in China, NCT02010775 in masseter muscle hypertrophy, and NCT01797094 in upper facial lines in Japan. Enrollment ranged from 101 to 417 participants across these studies.

Is botulinum toxin Type A the same as botulinum toxin Type A (44U) or botulinum toxin Type A (200U)?

Yes. Botulinum toxin Type A is also known as botulinum toxin Type A (44U), botulinum toxin Type A (200U), Botulinum toxin Type A Dose 1, and botulinum toxin Type A (24 U). These names refer to the same AbbVie (ABBV) asset in Phase 2 development.
