Osteoarthritis Clinical Trial
Official title:
Comparative Assessment of Viscosupplementation With Polynucleotides and Hyaluronic Acid to Viscosupplementation With Hyaluronic Acid in the Treatment of Osteoarthritis of the Knee. Randomized, Double-blind, Controlled Study
The purpose of the study is to assess the validity of the polynucleotide within the intra articular treatment of osteoarthritis of the knee, comparing it with that of hyaluronic acid, the most commonly used.
This study is double-blind, controlled, randomized.The aim of the study is to evaluate the
efficacy, safety and tolerability of polynucleotides and hyaluronic acid gel (PNHA, class III
medical device) for intra-articular infiltration in treating pain in osteoarthritis (OA)
patients knee.
This study will involve patients with osteoarthritis who comply with the inclusion and
exclusion criteria. One hundred patients between the ages of 45 and 70 will be enrolled in
the study and randomized to receive one of the following treatment groups:
Group A) Polynucleotides and Hyaluronic Acid (PNHA) Group B) Hyaluronic Acid (HA) The
treatment will be administered through intra-articular infiltration, a weekly infiltration in
the affected knee, for a total of 3 infiltrations (T0, T1 and T2).
The use of non-steroidal anti-inflammatory drugs (NSAIDs) was permitted, but the use of
paracetamol 1 cp 1000 mg every 12 hours, or Meloxicam 15 mg a tablet after meals every 12
hours, was recommended.
In case of grug taking: the number of days when the patient used NSAIDs, the commercial name
and the NSAID dosage used were reported in the CRF.
Study visit:
- T0 start study: inclusion in the clinical trial and assignment of the randomization
number; radiography; clinical study start-up evaluation; fill in the WOMAC
questionnaire; infiltration No. 1.
- T 1 after 1 week from the beginning of the study: infiltration No. 2.
- T 2 after 2 weeks from the beginning of the study (end of treatment): infiltration No.
3.
FOLLOW UP:
- T 3 after 2 months from the beginning of the study: clinical evaluation; fill in the
WOMAC questionnaire.
- T 4 after 6 months from the start of the study: clinical evaluation; fill in the WOMAC
questionnaire.
- T 5 after 1 year from the beginning of the study: clinical evaluation; fill in the WOMAC
questionnaire.
- T 6 after 2 years from the beginning of the study: radiography; clinical evaluation;
fill in the WOMAC questionnaire.
At T6 visit, the patient completed the study. A 24-month study period is calculated for each
patient.
Any adverse event that occurred during the study period was recorded.
