News - Старые лекарства, новый потенциал: поиск средств против старения

In recent years, the scientific community has been abuzz with the potential of generic drugs like metformin and rapamycin, long-established for other medical uses, possibly holding the key to slowing the aging process. Despite success in animal models, the leap to human trials remains elusive. Pharmaceutical companies face economic roadblocks; clinical trials for such aging therapies are prohibitively expensive, with no viable profit margins from off-patent drugs. This skepticism is rooted in financial pragmatism rather than corporate conspiracy, as many critics of the industry suggest. "Repurposing these drugs doesn't make financial sense for the industry," admitted experts at the 12th Aging Research and Drug Discovery meeting. Clinical trials, especially Phase 3 trials, require colossal investments, and the return must justify the expenditure. For drugs like metformin and rapamycin, the economics are simply unfeasible. Metformin costs about $4-$20 monthly, while rapamycin ranges from $40-$150, prices far too low for companies to sponsor extensive trials without patent monopolies. Additionally, 'aging' itself remains an unattractive target since it is not yet designated a reimbursable condition by insurers. However, pharmaceutical strategies are adapting. New patented drugs are developed for specific conditions with potential side benefits—their impact on aging biomarkers is also measured during trials. The hope is to parallel aging's recognition with that seen in obesity, transforming it from a lifestyle topic to a treatable medical condition. As this strategy evolves, the endorsements from regulators will be essential. While industry hesitates, academic and independent efforts are burgeoning. The American Federation for Aging Research, seeking support for the TAME Trial, aims to study metformin's effect on age-related diseases in 3,000 seniors. Simultaneously, The University of Texas at San Antonio has secured backing from the National Institute on Aging to undertake a limited but promising rapamycin study. These initiatives signal a step forward on aging-related drug research, bypassing profit motives to address the public wellness promise these drugs may harbor.
