phenoxybenzamine and Leiomyoma

phenoxybenzamine has been researched along with Leiomyoma in 6 studies

Phenoxybenzamine: An alpha-adrenergic antagonist with long duration of action. It has been used to treat hypertension and as a peripheral vasodilator.

Leiomyoma: A benign tumor derived from smooth muscle tissue, also known as a fibroid tumor. They rarely occur outside of the UTERUS and the GASTROINTESTINAL TRACT but can occur in the SKIN and SUBCUTANEOUS TISSUE, probably arising from the smooth muscle of small blood vessels in these tissues.

Trial Outcomes

Change in Post-Ice Provocation Visual Analog Score (VAS) Between Week 12 and Week 24

The VAS is a commonly used validated tool for assessment of pain. The 10-cm VAS was used to assess current patient pain/discomfort before and after application of ice to study lesions. A clinically meaningful change in chronic pain intensity using the VAS has been determined as a reduction of 2 points or 30%. Scale is 0-10. 10 denotes worse pain than 0. (NCT00971620)
Timeframe: Between week 12 and 24

InterventionScore (Median)
BTX-A4.10
Placebo/Saline-0.30

Change in Worst Lesional Pain in the Past Week Based on Brief Pain Inventory

Change in worst lesional pain in the past week based on Brief Pain Inventory (BPI) from Week 0 to Week 4 in treated patients versus controls. The BPI uses an arbitrary units on a 0-10 scale. For the purposes of the statistical calculation, a difference of 1 standard deviation between groups at baseline vs. week 4 was considered significant. Any BPI value above zero (no pain) is abnormal. The mean change indicates mean change in pain score. (NCT00971620)
Timeframe: Between week 0 and week 4

Comparison of Change in Skin Related Quality of Life by Total Dermatology Life Quality Index (DLQI) at Week 0 vs. Week 4

The DLQI is a 10-question quality of life survey which has been extensively validated and frequently used in dermatologic disorders such as atopic dermatitis, acne, and psoriasis. Score is 0-30 based on 10 questions. The higher the score, the more quality of life is impaired. (NCT00971620)

Immunohistochemical Staining of Cutaneous Leiomyomas for Acetylcholinesterase (AchE) Before (i.e.,Week 0) and 12 Weeks After Botulinum Toxin Administration

AchE staining was scored as 0 (none), 1 (rare), 2 (scattered), or 3 (focal or greater). (NCT00971620)
Timeframe: Week 0 vs. week 12

BTX-A1.00

Immunohistochemical Staining of Cutaneous Leiomyomas for C-fos Before (i.e., Week 0) and 12 Weeks After Botulinum Toxin Administration

c-fos, a marker of neuronal activation after pain stimulation, was scored as 0 (none), 1 (scattered), 2 (<66% of tumor cells), or 3 (≥66% of tumor cells). (NCT00971620)
Timeframe: Week 0 vs. week 12

Median Change in Average Pain Between Two Arms

Change in average pain was assessed by the Brief Pain Inventory (BPI). The BPI is a validated pain assessment tool that assesses severity of pain, location of pain, impact of pain on daily functions, pain medications, and amount of pain relief in the past 24 hours or past week (e.g. scale of 0-10 (worst pain)).

Specific Skin Pain-Related Question on the Dermatology Life Quality Index

"The DLQI is a 10-question quality of life survey which has been extensively validated and frequently used in dermatologic disorders such as atopic dermatitis, acne, and psoriasis. Participants response to the question Over the last week, how itchy, sore, painful or stinging has your skin been? was assessed by the Dermatology Life Quality Index. This outcome refers to a single specific question on the DLQI, so the range for this outcome is 0-3. Lower values in the DLQI indicate less impairment (or greater improvement) in life quality from the skin disease." (NCT00971620)

Visual Analog Scale (VAS) of Patient Perceived Pain at Leiomyoma Site Prior to Ice Provocation at Week 0 vs. Week 4

The VAS is a commonly used validated tool for assessment of pain. For this measure, a 10-cm VAS was used to assess current patient pain/discomfort before application of ice to study lesions at week 0 and week 4. A clinically meaningful change in chronic pain intensity using the VAS has been determined as a reduction of 2 points or 30%. Range is 0-10; 0 is no pain and 10 is worst possible pain. (NCT00971620)

Worst Pain Severity

Pain severity was assessed by the Brief Pain Inventory (BPI). The BPI is a validated pain assessment tool that assesses severity of pain, location of pain, impact of pain on daily functions, pain medications, and amount of pain relief in the past 24 hours or past week (e.g. scale of 0-10 (worst pain)). This outcome was based on a single 0-10 question on the BPI. (NCT00971620)
