ARB

The goal of this clinical trial is to learn if drug OPGx-BEST1 works to treat BVMD and ARB Bestrophinopathy. It will also learn about the safety of drug OPGx-BEST1. The main questions it aims to answer are: Evaluate the safety and tolerability of drug OPGx-BEST1 in one eye (the treatment eye), for 5 years post-injection, in participants with BVMD or ARB. A second question it aims to answer is identification of the most appropriate dose strength of OPGx-BEST1 for clinical development. Evaluate the efficacy of single injection of OPGx-BEST1 in one eye for 5 years post-injection. What medical problems do participants have when taking drug OPGx-BEST1?

Some authors have proposed the use of the flu vaccine to reduce the severity of COVID-19 cases, while some have proposed the use of ACE Inhibitors (ACEI) or Angiotensin Receptor blockers (ARB), since this virus shares hemagglutinin as a transmission mechanism and acts on the ACE2 enzyme during infection. Other authors described how none of the elderly patients receiving antihistamines and azythromycin in two nursing homes in Toledo -Spain- during the first wave died or needed hospital admission, even considering that 100% of residents had a positive serological test after that wave. Other authors have described a positive evolution in patients receiving amantadine for their Parkinson's disease. The aim is to evaluate whether the admitted patients who are previously vaccinated or those who were already receiving these treatments showed a better evolution.
