Montelukast in ENL Reaction
Recruitment status was: Not yet recruiting
Objective of the trial is to assess the safety and efficacy of Montelukast in treatment of Erythema Nodosum leprosum (ENL) reaction in multibacillary leprosy patients either in combination with prednisolone or alone.
Hypothesis is that montelukast will reduce the severity of ENL reaction in Multibacillary leprosy patients without causing an unacceptably high incidence of adverse effects.
Design is a multicentre hospital-based single-blind prospective trial for leprosy patients with ENL reaction. prior written consent will be taken from the patients who will undergo the trial.
Endpoints are decrease in severity of ENL and absence of new nerve function impairment
|Erythema Nodosum Leprosum Leprosy||Drug: montelukast in treatment of ENL reaction|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind
Primary Purpose: Treatment
|Official Title:||Montelukast as an Alternative or Supplementary Treatment in ENL Reaction in Leprosy|

- absence of new nerve function impairment
- incidence of adverse effects
|Study Start Date:||December 2006|
|Estimated Study Completion Date:||June 2009|
Leprosy is still a common medical problem in many countries including Bangladesh, and currently there are at least 3500 leprosy patients in this country at risk of ENL reaction, which is a distressing complication of Multibacillary (MB) leprosy liable to result in permanent disability if not well treated. The drug of choice is either prednisolone ( which often causes adverse effects especially with prolonged use) or thalidomide which is not available in Bangladesh.Clofazimine in high doses is recommended as an alternative but supplies are difficult to obtain. Hence the need for an alternative drug which could be used as a steroid sparing agent or an alternative to steroids in ENL reaction. Montelukast is a leukotriene inhibitor already available on the open market in this country as an immunomodulator, and a small clinical trial with zafirlukast ( very similar drug) suggested that drugs in this group may be effective for ENL.
This is a phase two trial to assess the safety and efficacy of montelukast as an alternative or supplementarry treatment for ENL reaction.
Eligible patients presenting to one of the participating hospitals with ENL reaction will be randomly allocated to one of three groups to receive prednisolone only or prednisolone plus montelukast or montelukast alone. Any patients who have major contra-indications to steroids will be put into a separate observational group and receive montelukast only.
Drug regimens are prednisolone starting at 40 mg od nd tapered over 12 weeks. Montelukast 10mg od for 16 weeks.
The patients will be monitored weekly for 8 weeks then monthly for 4 months.
At least 20 patients will be enrolled in each group.
The patients will be closely observed for adverse effects, and any who deteriorate will receieve additional steroid according to the protocol. Any who develop new nerve function impairment will be removed from the trial and given a full course of prednisolone.
Analysis will be done on an intention to treat basis and will look for any statistically significant difference in ENL score at 2 weeks, 12 weeks and 24 weeks, or a difference in the number of patients who develop new nerve function impairment, as well as the incidence and severity of any adverse effects in each group.
