Efficacy and Safety of Minodronate in Patients With Low Back Pain

Efficacy and Safety of Minodronate in the Treatment of Postmenopausal Osteoporosis With Low Back Pain: a Single-centre and Randomized Controlled Trial

This study will provide objective evidence for the efficiency and safety of minodronate in the treatment of postmenopausal osteoporosis with low back pain protocol. Furthermore, it will be helpful to evaluate the quantitative relationship between bone metabolic markers (BTM) and bone mineral density (BMD) in patients with osteoporosis under different ages.

Study Overview

• Status: Not yet recruiting
• Conditions: Postmenopausal Osteoporosis
• Intervention / Treatment: Drug: Minodronate; Drug: Alendronate

Detailed Description

The study is a randomized, parallel controlled clinical trial in Chinese postmenopausal OP patients receiving minodronate or alendronate. Minodronate will be administered once daily for 12 weeks, and alendronate will be administered once daily for 12 weeks. This study is divided into two stages: the first stage is 12 weeks, and at the end of the first stage, the results of patients' back pain and gastrointestinal adverse reactions will be summarized; the second stage is 12 weeks, and the pharmacokinetic and pharmacodynamic characteristics of patients will be summarized at the end of the second stage. The VAS score in this study rangs from 0-100 mm. During the screening, the patient's past pain relief methods, such as pain medication or the way of life intervention will be recorded. The use of the above methods during the patients' treatment will be prohibited to prevent interference with the results of the clinical trials. During the treatment, if patients experience sudden aggravation of low back pain, the VAS score is more than 70, and the patients could not bear the pain, a rescue drug (acetaminophen) will be used uniformly to relieve the pain. Throughout the trial, a total of 5 follow-up visits will be planned. The VAS score, PK&PD sampling, BMD evaluation, and Izumo scale score will be calculated.
