A multicentric, double-blind, controlled, clinical trial was carried out to compare the efficacy of a combination of rifampicin 600 mg plus ofloxacin 400 mg plus minocycline 100 mg (ROM) administered as single dose with that of standard WHO/MDT/PB six months regimen. The study subjects were 236 previously untreated, smear-negative patients, without nerve trunk involvement and having only two or three skin lesions. Randomization was done on individual patient basis. Results were analysed for mean clinical score for improvement, marked clinical improvement and complete clinical cure at the time of release from treatment and at 12 months and 18 months of follow-up.

Clinical improvement was seen in most patients in both regimens. Marked improvement (i.e., more than 90% reduction in clinical score) at 18 months was seen in 46.2% and 53.4% of the patients treated with ROM and standard regimens, respectively. But, significant difference in favour of standard PB regimen was seen in patients with three skin lesions and in patients in whom more than one body part was affected. Reversal reaction and adverse drug reactions were minimal in both groups.
