Target Sample Size
Total Sample Size="160" Sample Size from India="160" Final Enrollment numbers achieved (Total)= "161" Final Enrollment numbers achieved (India)="161"
This was a Phase III, randomized, two-arm, multicenter, active-controlled, parallel-group, double-blind, comparative study in patients with wet AMD.
The study was conducted at total 20 geographically distributed centers in India (one site did not screen any patient), having qualified Investigators. The study was initiated only after the receipt of regulatory and EC approval. Total 187 patients were screened to randomize 161 patients from 20 geographically distributed centers in India.
Each clinical trial site was provided with randomization number schedule. After obtaining informed consent, patients were screened by undergoing various assessments and after confirming the eligibility, total 161 patients were randomized in 2:1 ratio to either Sun’s Ranibizumab arm Solution 0.05 mL (0.5 mg) intravitreal injection or Reference Biologic arm (Accentrix®) intravitreal injection in double-blind fashion, as per randomization schedule.
Only one eye per patient was selected as “study eyeâ€. Only study eye received the study drug. Ranibizumab (Test or Reference) 0.5 mg was administered as intravitreal injection on the Day 1, Day 28, Day 56 and Day 84. Reference drug Accentrix® was used in this study.
Study was amended thrice.
Version No. 1.2; dated 29/SEP/2020: CTCAE as criteria for safety was considered for this study
Version 2.0 dated 12/FEB/2021: Exclusion criteria no. 21 modified to ‘Patients with HbA1c > 7’ was considered a relevant population for Ranibizumab in wet-AMD indication. Moreover, these subjects were not excluded in innovator Pivotal clinical trials conducted for approval in this indication.
Version No. 2.1; dated 30/APR/2021: Added diabetic retinopathy as a separate exclusion criteria no. 11 as per SEC recommendations and deleted diabetic retinopathy in exclusion criteria no. 12 as per SEC recommendations
Total duration of the trial was 126 (14 days screening + 112 days treatment period) comprising of total 7 visits: The study was planned as follows:
Screening: 14 days (Day -14 to Day -1)
Visit 2: Randomization/Day 1
Visit 3: Day 7 ±2
Visit 4: Day 28 ±2
Visit 5: Day 56 ±2
Visit 6: Day 84 ±2, End of Treatment (EOT)
Visit 7: Day 112 ±2, End of Study (EOS)/Early Termination (ET)
The efficacy, safety and immunogenicity were assessed during the study period. Patients who are withdrawn/ terminating early from the study completed EOS visit assessment. Day 84 were End of treatment day.
After completion of Study, based on the OCT result and Investigator’s judgement patient were further shifted on Pro Re Nata (PRN) Regimen or Treat and Extend (T&E) Regimen. After completion of study, the patient responding to treatment were provided with drug beyond the clinical trial till such duration as recommended by the Principal Investigator or as per rules of post-trial access of investigational product.
Study results conclusion:
Based on results of primary endpoint, Sun’s ranibizumab biosimilar can be considered therapeutically equivalent to reference biologic product, Accentrix®. Sun’s ranibizumab was comparable to reference product for all secondary endpoints as well. Overall, both the products were safe. There were no additional safety or immunogenicity concerns emerged during the study.
