Condition(s) targeted: Bell's Palsy

Intervention: Prednisolone + placebo (Drug); Valaciclovir + placebo (Drug); Prednisolone + valaciclovir (Drug); Placebo + placebo (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: Uppsala University Hospital

Official(s) and/or principal investigator(s):

Summary

The main objective of this study is to study the effects of prednisolone and valaciclovir, with equal importance, compared to placebo for the treatment of Bell´s palsy. The combination of prednisolone and valaciclovir will also be studied.

Clinical Details

Official title: A Multicentre Placebo-Controlled Evaluation of Prednisolone and/or Valaciclovir for the Treatment of Bell's Palsy

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: The primary endpoint will be the time to complete clinical recovery from Bell's palsy.

Secondary outcome:

Proportion of patients with complete healing of palsy compared to those with incomplete healing at 12 months after onset.

Influence on outcome at 12 months by time in hours from onset of palsy until beginning of study medication.

Proportion of patients that develop severe palsy during the first week from onset.

The total duration of pain, in or around the ipsilateral ear or the ipsilateral side of the face, from onset of palsy.

The proportion of subjects with severe pain (more than VAS 3) in the different treatment arms.

Occurrence of synkinesia in the different treatment arms at any time.

Occurrence of facial spasm or contracture in the different treatment arms at any time.

Severity of remaining facial symptoms in patients not healed at 12 months and at each prescheduled study visit.

Detailed description: Study Design: This is a multicentre randomised double-blind placebo-controlled study. Study medication: Prednisolone 60 mg per day for 5 days, after that tapering 10 mg per day for a total treatment time of 10 days. Valaciclovir 1000 mg 3 times per day for 7 days. Prednisolone and valaciclovir are used in combination or separately. One patient of four receives placebo. Study Duration: Study medication will be taken during 10 days. The subjects will be followed for 12 months after initiation of treatment. Follow-up visits will be 11-15 days after start of therapy and at 1, 2, 3, 6 and 12 months after the onset of palsy. Study Setting: The study will be conducted in 17 ENT-clinics in Sweden and Finland, which will be monitored by the members of the board of the Scandinavian Bells Palsy Study (SBPS) Study Subjects: Otherwise healthy subjects with unilateral acute idiopathic facial palsy. A total of 800 subjects will be included in the study. Study Treatments: The subjects will be randomised to one of the following treatment arms for oral administration of study drug: 1. Prednisolone + placebo 2. Valaciclovir + placebo 3. Prednisolone + valaciclovir 4. Placebo + placebo Treatment will be initiated within 72 hours of onset of palsy and continued during 10 days. Measurements: The first follow-up clinical examination is scheduled within 3 days after completed treatment. Further follow-up visits are scheduled at 1, 2, 3 and 6 months from onset of palsy. If complete recovery has occurred at the 2 month visit, the 3 and 6 months visits are not necessary. If complete recovery is present at 3 months the 6 month visit can be excluded. A final follow-up exam is always performed at 12 months. The clinical examination includes a routine examination of ear, nose and throat, grading of the palsy according to the Sunnybrook and House Brackmann grading scales and registration of other symptoms as pain, eye irritation, dysacusis and impaired taste. Blood tests for Lyme Borreliosis are drawn at the acute (the first) visit and at the follow-up visit at 2 months. Primary Endpoint: The primary endpoint will be the time to complete clinical recovery (defined as 100 on the Sunnybrook facial nerve grading scale) from Bell's palsy. The subjects will be categorised as healed or not healed at months 1, 2, 3, 6 or 12 months. Treatments will be compared using the Generalized Wilcoxon rank sum test. Patients where data are missing and there is no healing time will be included as censored at the last visit when the patient was not healed. Secondary endpoints: The secondary endpoints of this study are comparisons between the different treatment arms with regard to:

- Proportion of patients with complete healing of palsy compared to those with incomplete

healing at12 months after onset.

- Influence on outcome at 12 months by time in hours from onset of palsy until beginning

of study medication.

- Proportion of patients that develop severe palsy during the first week from onset.

- The total duration of pain, in or around the ipsilateral ear or the ipsilateral side of

the face, from onset of palsy.

- The proportion of subjects with severe pain (more than VAS 3) in the different

treatment arms.

- Occurrence of synkinesia in the different treatment arms at any time.

- Occurrence of facial spasm or contracture in the different treatment arms at any time.

- Severity of remaining facial symptoms in patients not healed at 12 months and at each

prescheduled study visit as recorded by Sunnybrook Facial Grading System. Safety Evaluations: Adverse events will be assessed during the first study month. Adverse events will be reported in the patient's files and in the patient CRF for this study.
