Key people at RefleXion Medical.
RefleXion Medical has raised $826.0M across 11 funding rounds. Most recently, it raised $105.0M Other Equity in November 2023.
RefleXion Medical is a privately held therapeutic oncology company developing the RefleXion X1, the world's first biology-guided radiotherapy (BgRT) system for cancer treatment.[1][2][4] The SCINTIX technology uses positron-emission tomography (PET) signals from cancer cells—acting as real-time biological beacons—to guide radiation delivery with sub-second precision, even for moving or multiple tumors, serving radiation oncologists and patients with early- or late-stage cancers like lung tumors.[2][3] It solves key limitations of conventional radiotherapy, such as targeting mobile tumors without large margins and enabling multi-tumor treatment in one session using a single radiotracer injection, marking a shift from single-tumor focus.[2][3] The company has shown strong growth momentum, including FDA clearance for stereotactic body radiotherapy (SBRT), stereotactic radiosurgery (SRS), and intensity-modulated radiotherapy (IMRT); Breakthrough Device Designation for lung tumors; the first patient treated worldwide at Stanford; and an $80 million funding round.[1][3][4]
Headquartered in Hayward, California, RefleXion combines medical physics, nuclear medicine, and radiotherapy to advance cancer care, with early validation from the National Cancer Institute and peer-reviewed publications in *Medical Physics*.[1][4]
RefleXion Medical was founded in 2009 by Sam Mazin, Ph.D. (co-founder, CTO) and Akshay Nanduri (co-founder), stemming from a discussion at Stanford University where they envisioned using cancer's biology via PET to simultaneously see and treat multiple tumors.[2][4][6] Mazin, with expertise in medical physics, and Nanduri turned this into the BgRT concept, publishing the first peer-reviewed paper in *Medical Physics* (the American Association of Physicists in Medicine journal) on simulated lung and prostate cancers, laying the clinical foundation.[4] Early traction included National Cancer Institute funding (1R43CA153466-1A1) and investor interest from blue-chip backers like Sofinnova Partners.[1][4]
Pivotal moments followed: Stanford Cancer Center treated the first patient with the RefleXion X1 for image-guided radiotherapy; the FDA granted Breakthrough Device Designation for lung tumors; and the company raised $80 million to expand options.[1][3][4] Leadership evolved with Todd Powell as CEO and President, Shervin Shirvani as Chief Medical Officer, and a board including Antoine Papiernik (Sofinnova), Fred Moll, and others.[5]
RefleXion stands out in radiation oncology through these key advantages:
RefleXion rides the precision oncology trend, merging AI-adjacent real-time imaging (PET/CT) with radiotherapy to address metastatic cancer, where 90% of deaths occur, amid rising demand for targeted therapies post-immunotherapy era.[2][4] Timing aligns with FDA's push for breakthrough devices and radiotracer advances (e.g., FDG-PET standardization), amplified by market forces like aging populations and medtech funding resurgence.[1][3] It influences the ecosystem by pioneering BgRT—potentially increasing therapeutic ratios for high-dose treatments—and partnering with leaders like Stanford, fostering clinical trials that could standardize biology-guided approaches and attract techbio investments.[3][4]
RefleXion is poised to disrupt radiation oncology by commercializing BgRT post-FDA clearances, with phase 1 trials at Stanford evaluating safety for broader cancers and expansion into multi-tumor protocols.[3] Trends like AI-enhanced imaging, novel tracers, and value-based care will accelerate adoption, potentially positioning it as a standard for stage IV patients. Its influence may grow through partnerships and scale, evolving from innovator to ecosystem shaper—building on its biological edge to redefine fierce cancer battles.[2][4] This Hayward trailblazer, born from a Stanford spark, exemplifies medtech's paradigm shift.
