A clinical study to evaluate efficacy and safety of AHPL/AYTAB/0313 tablet in subjects suffering from osteoarthritis of knee(s)

BACKGROUND: Osteoarthritis (OA) is the most common form of arthritis with unsatisfactory treatment outcomes. OBJECTIVES: To evaluate efficacy and safety of AHPL/AYTAB/0313 tablet in subjects with OA of knee joint. STUDY DESIGN: Prospective, open-label, single-arm clinical study conducted in daily clinical practice setting. METHOD: Subjects were advised to take 2 AHPL/AYTAB/0313 tablets twice daily orally after meals for 180 days. 48 subjects completed the study. The primary endpoints were changes in mean visual analogue scale (VAS) pain score and WOMAC score. Secondary endpoints were quality of life, time to walk 50 feet, knee joint swelling, use of analgesic drug as rescue medicine, and safety parameters. RESULTS: At baseline visit, the mean index knee joint pain (VAS) score was 82.29 ± 15.19, which reduced significantly to 19.38 ± 13.75 on day 180. The mean WOMAC combined score at baseline was 39.94 ± 11.67, which reduced significantly to 09.58 ± 05.77 (76.0%) on day 180. The mean WOMAC pain score at baseline was 09.65 ± 02.91, which reduced significantly to 02.06 ± 01.46 on day 180. The mean WOMAC stiffness score at baseline was 03.48 ± 01.58, which reduced significantly to 00.63 ± 01.08 on day 180. The mean WOMAC difficulty score at baseline was 26.81 ± 09.63, which reduced significantly to 06.90 ± 04.78 on day 180. The mean walking time to walk 50 feet reduced significantly by 40% on day 180. Not a single subject was known to have knee joint swelling from 150 days onwards. Only 5 subjects were using analgesic as rescue medicine on day 180. Twenty-six subjects had adverse events (AEs). Most of the AEs were not associated with the study medication. Vitals and all the safety laboratory parameters were within normal limits both at baseline and on day 180. CONCLUSION: “AHPL/AYTOP/0113” tablet is safe and significantly effective in reducing pain, swelling, and stiffness of knee joints and improving mobility of knee joints in patients with OA.
