NephroSant, a kidney health spin out of UC San Francisco, today announced it has closed its oversubscribed Series A funding round of $16 million. DaVita Venture Group led the investment round, with participation from DigitalDx Ventures and other previous investors. The funding will be used to support research and development and the launch of NephroSant's first product: Qsant™, a needle-free urine test that helps determine if a patient's body is rejecting a transplanted kidney. 

"We are very excited about the opportunity to work with DaVita, a recognized leader in kidney care," said Dr. Minnie Sarwal, CEO and founder of NephroSant, as well as Professor of Surgery at UCSF. "Their expertise and experience provide the perfect complement to the vision and focus of NephroSant to redefine kidney health." 

Qsant™ is the first home-based urine test designed specifically for the detection of kidney transplant rejection, without the need for a costly and invasive biopsy. This test uses multiple biomarkers including a proprietary technology for measurement of urine cell-free DNA. Currently, up to 40% of all kidney transplant recipients result in clinical or sub-clinical rejection. Identifying and predicting rejection earlier will enable clinicians to intervene sooner and help patients live a longer life.

"Transforming kidney care requires bold innovation, which is precisely why DaVita Venture Group invested in NephroSant and its game-changing solution that helps patients manage their transplanted kidney health," said Dr. Jeff Giullian, Chief Medical Officer for DaVita. "As a transplant nephrologist, I look forward to a future where patients not only have greater access to a transplant but also can extend the life of a transplant with Qsant™."

By giving the patient the option of an in-home sample collection method, Qsant™ enhances patient convenience and safety, especially important in the current COVID-19 pandemic. Moreover, Qsant™ requires a single urine void instead of a 24-hour urine collection.  Qsant™ uses a proprietary-based algorithm to generate a quantitative rejection risk unique for each patient, referred to as the patient's personalized "Q-Score."

"As Nephrosant's first institutional investor, we are honored to welcome DaVita Venture Group and follow them into this next round of funding," shared Michele Colucci, founder and Managing Partner for DigitalDx Ventures. "Dr. Minnie Sarwal's non-invasive urine tests for kidney health and transplant rejection are revolutionary, combining a patient-centric approach and exceptional accuracy. We are very fortunate to be able to support this incredible female founder and play an integral role on the board as we pursue our mission to make quality healthcare more accessible to all."
