A 38-year-old man from rural Maharashtra presents with a 2-year history of hypopigmented macules on his trunk and arms. On examination, he has 5 well-demarcated lesions with diminished sensation to light touch and temperature. Slit-skin smear from the lesion shows acid-fast bacilli (AFB) with a bacillary index of 2.5. Lepromin test is negative. Based on the clinical and bacteriological findings, what is the appropriate MDT regimen for this patient?
