Summary

The study is an investigator-initiated randomized, placebo-controlled, double-blind, parallelgroup trial. Eighty subjects with PTH will be included and randomized 1:1 for treatment with BTX-A or placebo (isotonic saline). The study comprises a 4-week baseline phase before injection of either active drug or placebo followed by a 12-week evaluation period. Treatment will be double-blind, and subjects will only receive one treatment cycle. Endpoints will be assessed in the evaluation period (weeks 5 to 8) compared to baseline (weeks -4 to -1).

Botox 200 UNT Injection

A concentration of 50U/mL BTX-A is prepared using saline in four syringes: one with 1 mL, one with 0.8 mL, one with 0.7 mL, one with 0.6 mL. This equals a total administration dose of 155U. A total of 155U BTX-A will be injected at day 1 (first day in week 1) by subcutaneous injections according to the PREEMPT protocol.
