ARPA-H Funds Human Trials for Healthspan

- The "PROactive Solutions for Prolonging Resilience" (PROSPR) initiative is the specific ARPA-H program funding these trials, with a budget of up to $144 million. Its goal is to establish a "healthspan industry" by identifying early biomarkers of aging. The current director of ARPA-H is Dr. Alicia Jackson. - Among the private companies receiving funding are Cambrian BioPharma and Linnaeus Therapeutics. Linnaeus was awarded up to $22 million to test its lead drug, LNS8801, an oral agonist of the G protein-coupled estrogen receptor, which has shown preclinical promise in cardiometabolic health, inflammation, and neurodegeneration. - Another PROSPR-funded project, led by researchers from Brown University and the University of Rochester, will test if Censavudine, a drug originally developed for HIV, can suppress the activity of "selfish DNA" known as retrotransposons to reduce age-related inflammation. - For consumer health apps, building trust is paramount and can be achieved through transparent privacy policies written in plain language and by providing clear information on the app's creators and their medical credentials. Given that healthcare data is considered highly valuable on the black market, employing end-to-end encryption and secure authentication methods like OAuth 2.0 is a baseline for credibility. - Successful user retention strategies in health apps often involve gamification, such as reward systems with points and badges, to foster consistent engagement. For instance, the meditation app Insight Timer achieved a 16% Day 30 retention rate, nearly double its main competitors, by incorporating community-based features and progress statistics. - When integrating wearable devices, developers are increasingly using unified APIs to connect with Apple Health, Garmin, Fitbit, Oura, and Whoop, which can reduce development time from months to weeks. It is important to note that Apple HealthKit does not have a backend API, meaning data must be synced through a native iOS app with user consent. - For early-stage digital health fundraising, founders are often advised to seek non-dilutive funding from government grants or accelerator programs to avoid giving up too much equity early on. Crafting a compelling narrative that includes personal experiences with the healthcare system can be a powerful tool for gaining investor interest. - Research into the experiences of patients with chronic conditions reveals common frustrations, such as having to repeatedly describe their condition to different providers and feeling that their doctor doesn't understand the reality of managing their condition at home. Many express a desire for tools that offer comprehensive symptom and lifestyle tracking to better communicate their experiences.
