Efficacy and Safety Study of MYOBLOC® in the Treatment of Adult Lower Limb Spasticity

A Phase 2/3, Multicenter, Randomized, Double-Blind, Placebo-Controlled, Single-Treatment Efficacy and Safety Study of MYOBLOC® in the Treatment of Adult Lower Limb Spasticity

Phase 2/3, randomized, double-blind, placebo-controlled, single-treatment, multicenter trial assessing the efficacy and safety of MYOBLOC for the treatment of lower limb spasticity, in adults followed by an open-label extension safety trial.

Study Overview

• Status: Terminated
• Conditions: Spasticity
• Intervention / Treatment: Drug: Phase 2; Placebo; Drug: Phase 3; MYOBLOC; Drug: Phase 3; Placebo; Drug: Phase 2; Low Dose MYOBLOC (15,000 Units); Drug: Phase 2; High Dose MYOBLOC (20,000 Units)

Detailed Description

Phase 2, randomized, double-blind, placebo-controlled, single-treatment, multicenter trial will compare the efficacy and safety of two doses of MYOBLOC (15,000 Units and 20,000 Units)versus volume-matched placebo in the treatment of lower limb spasticity in adults. An interim analysis will evaluate all available safety and efficacy data from the Phase 2 double-blind trial in order to recommend which dose will be evaluated in subsequent Phase 3 trial. The Phase 3, randomized, double-blind, placebo-controlled, single-treatment, multicenter trial will compare the efficacy and safety of MYOBLOC versus placebo in the treatment of lower limb spasticity in adults. Subjects who complete either the Phase 2 or Phase 3 trial will continue into an open-label extension part of the study where each will receive 4 separate treatments of MYOBLOC (20,000-25,000 Units) ~13 weeks apart for lower limb spasticity.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The Change From Baseline in the Modified Ashworth Scale (MAS) Score in the Tone of the Ankle Plantar Flexors at Week 4 Post-injection.	The Modified Ashworth Scale (MAS) is an internationally accepted and validated instrument used to measure resistance during passive soft-tissue stretching. Resistance will be measured and recorded using a 6-point scale ranging from 0 (no increase in muscle tone) to 4 (affected part[s] rigid in flexion or extension). The post-injection MAS score is subtracted from the baseline MAS score to yield the change from baseline MAS score. A change from baseline MAS score <0 represents a better outcome.	Baseline and Week 4
The Clinical Global Impression of Change (CGI-C) Score in Functional Ability at Week 4 Post-injection	The Clinical Global Impression of Change (CGI-C) scale is a single item clinician assessment of how much the patient's functional ability has improved, worsened or has not changed relative to the patient's baseline state prior to treatment (injection). The CGI-C is rated on a 7-point Likert scale from 1 to 7, where 1 = "Very much improved", 2 = "Much improved", 3 = "Minimally improved", 4 = "No change", 5 = "Minimally worse", 6 = "Much worse", and 7 = "Very much worse". A CGI-C score <4 represents a better outcome.	Week 4

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Effect of MYOBLOC on the Caregiver Global Impression of Change (GGI-C) [Phase 2 and Phase 3]	An additional secondary endpoint is the Caregiver Global Impression of Change (GGI-C) score at Week 4 post-injection. The GGI-C scale is a single item caregiver assessment on how much the patient's ability to function has improved, worsened or has not changed relative to the patient's baseline state prior to treatment (injection). The GGI-C is rated on a 7-point Likert scale from 1 to 7, where 1 = "Very much improved", 2 = "Much improved", 3 = "Minimally improved", 4 = "No change", 5 = "Minimally worse", 6 = "Much worse", and 7 = "Very much worse". Successful therapy is indicated by a lower score (<4) in subsequent testing.	Week 4
Effect of MYOBLOC on the Caregiver Global Impression of Change (GGI-C) [Phase 2 and Phase 3]	An additional secondary endpoint is the Caregiver Global Impression of Change (GGI-C) score at Weeks 2, 8 and 13 (and, if applicable, at re-evaluation visit) post-injection. The GGI-C scale is a single item caregiver assessment on how much the patient's ability to function has improved, worsened or has not changed relative to the patient's baseline state prior to treatment (injection). The GGI-C is rated on a 7-point Likert scale from 1 to 7, where 1 = "Very much improved", 2 = "Much improved", 3 = "Minimally improved", 4 = "No change", 5 = "Minimally worse", 6 = "Much worse", and 7 = "Very much worse". Successful therapy is indicated by a lower score (<4) in subsequent testing.	Weeks 2, 8, and 13 (and, if applicable, at re-evaluation visit)
Effect of MYOBLOC on the Patient Global Impression of Change (PGI-C) [Phase 2 and Phase 3]	An additional secondary endpoint is the Patient Global Impression of Change (PGI-C) score at Week 4 post-injection. The PGI-C scale is a single item patient reported (self) assessment of how much his/her ability to function has improved, worsened or has not changed relative to his/her baseline state prior to treatment (injection). The PGI-C is rated on a 7-point Likert scale from 1 to 7, where 1 = "Very much improved", 2 = "Much improved", 3 = "Minimally improved", 4 = "No change", 5 = "Minimally worse", 6 = "Much worse", and 7 = "Very much worse". Successful therapy is indicated by a lower score (<4) in subsequent testing.	Baseline and Week 4
Effect of MYOBLOC on the Numeric Rating Scale of Pain (Pain-NRS) [Phase 2 and Phase 3]	An additional secondary endpoint is the change from baseline in the Pain Numeric Rating Scale (Pain-NRS) score at Week 4 post-injection. The Pain-NRS is a unidimensional measure of pain intensity in adults. It is a segmented numeric version of the visual analog scale (VAS) in which a respondent selects a whole number (0-10 integers) that best reflects the intensity of his/her pain. The common format is a horizontal bar or line. Similar to the VAS, the Pain-NRS is anchored by terms describing pain severity extreme on 11-point scale ranging from 0 ("no pain") to 10 ("worse pain imaginable"). A lower change from baseline Pain-NRS score (<0) represents a better outcome	Baseline and Week 4
Effect of MYOBLOC on the Walking Impairment Questionnaire (WIQ) [Phase 2 and Phase 3]	An additional secondary endpoint is the change from baseline (CFB) Walking Impairment Questionnaire (WIQ) percent scores at Week 4 post-injection. The WIQ is a 14-item survey of a patient's self-perceived walking distance (20, 50, 150, 300, 600, 900, 1500 feet), walking speed (1.5, 2, 3, 5 mph), and stair-climbing ability (12, 24, 36 stairs). Each item is rated on a 5-point Likert scale by degree of physical difficulty; where 0="unable", 1="much", 2="some", 3="slight", 4= "none". A percent maximal score (0-100%) for walking distance, walking speed, and stair-climbing is derived by dividing the sum of each rating multiplied by its respective distance, speed or number of stairs by the maximal score (14080, 46 or 288, respectively) multiplied by 100. A higher percent score represents less impairment. A higher change from baseline percent score (>0%) represents a better outcome.	Baseline and Week 4
Effect of MYOBLOC on Walking and Resting Comfort Scale (WRCS) [Phase 2 and Phase 3]	An additional secondary endpoint is change from baseline Walking and Resting Comfort Scale (WRCS) score at Week 4 post-injection. WRCS is a 5-item self-report assessment of patients degree of comfort he/she experiences when walking (with and without ankle-foot orthosis and with waking device) or at rest (with and without ankle-foot orthosis). Each item is rated on a 5-point scale ranging from "1=very comfortable" to "5=very uncomfortable". A higher change from baseline WRCS score (>0) represents a better outcome.	Baseline and Week 4
Effect of MYOBLOC on Modified Ashworth Scale (MAS) Responder Rate Tone of the Ankle Plantar Flexors [Phase 2 and Phase 3]	An additional secondary endpoint is the Modified Ashworth Scale (MAS) Responder Rate for MAS score in the ankle plantar flexors at Week 4 post-injection. The MAS is an internationally accepted and validated instrument used to measure resistance during passive soft-tissue stretching. Resistance will be measured and recorded using a 6 point scale ranging from 0 (no increase in muscle tone) to 4 (affected part[s] rigid in flexion or extension). The MAS responder rate is defined as the percent of subjects with ≥1 grade reduction in their change from baseline MAS score at Week 4. Values range from 0 to 100%. A higher percentage represents a greater number of responders.	Baseline and Week 4
