BackgroundThe regulation of the synthesis of the nerve growth factor and other neurotrophins is one of the dynamically developing areas of pharmacotherapy of neurological and mental disorders. Despite a large number of studies of various ligands of neurotrophin receptors, only a few have reached clinical application and only for ocular diseases. The aim of this narrative review was to systematize the main progress on neurotrophin-based pharmaceutics; to perform a comparative critical analysis of various therapeutic strategies, elucidate the underlying causes of clinical trial failures, and identify the most promising avenues for future development.MethodsThe literature search was conducted in PubMed, Google Scholar, Medline, and EBSCO, and the ClinicalTrials.gov database was used to track current clinical studies, along with the official websites of pharmaceutical companies. The search covered original studies published up to October 2025, with inclusion restricted to articles published in English. Articles describing specific pharmacological compounds that had reached the clinical trial stage were selected. Foundational biological research was referenced to contextually explain the mechanisms of action of the drugs and their therapeutic implications.ResultsRecombinant neurotrophins and synthetic molecules, the agonists and antagonists of their receptors, and cell-based gene therapy are promising means for the prevention and rehabilitation of ischemic conditions, as well as the treatment of neuropathic pain and neurodegenerative disorders such as Alzheimer's disease and Parkinson's disease. Some of these have undergone clinical trials, yet only neurotrophins for ocular diseases have been implemented in clinical practice: recombinant NGF-cenegermin and recombinant CNTF-Revakinagene taroretcel. The success of these eye drugs is likely attributable to their local administration, improved bioavailability, and low ocular immunoresistance.ConclusionsThe study identified limitations and future prospects for neurotrophin-based pharmaceuticals. For future clinical trials, attention should be paid to the pharmacogenetic profiles of the patients and the evaluation of the inflammatory status of the disease. Novel plasma biomarkers of the effectiveness are needed as well as TSPO-PET imaging. Drug delivery systems remain insufficient; therefore, efforts should focus on inducing endogenous neurotrophin production and developing highly selective agonists and antagonists of neurotrophin receptors. It is crucial to establish a favorable premorbid background before neurotrophin therapy to minimize immunoresistance.
