A group of emerging biotech and healthcare companies is gaining attention as they advance novel technologies across oncology, regenerative medicine, infection prevention, and precision radiotherapy—sectors that remain top priorities for global healthcare systems and investors alike. From late-stage cancer immunotherapy programs to next-generation hygiene platforms and regenerative biologics, these five companies represent distinct but complementary approaches to addressing high-value medical needs.
CS Diagnostics Corp. (OTCQB: CSDX) is emerging as a micro-cap medtech company positioned at the crossroads of infection control and oncology treatment support. CSDX is advancing CS Protect-Hydrogel, a tissue spacer designed to protect healthy organs during prostate cancer radiotherapy—an increasingly adopted tool in precision oncology.
According to the company, their CS Protect-Hydrogel is currently under FDA review. It appears there’s a low competitive landscape for this technology. CSDX’s main competitor for hydrogel spacers is Boston Scientific Corporation (NYSE: BSX). The competitor product SpaceOAR Hydrogel System was developed by Augmentix, Inc., which was fully acquired by Boston Scientific Corporation for a purchase price of USD $500 million upfront, plus a variable purchase price component of USD $100 million upon achievement of certain sales targets.
In parallel, The Company is commercializing MEDUSA, a smart disinfectant and hygiene platform expanding into medical-grade wet wipes and liquid formulations for institutional and consumer markets, addressing rising demand for hospital-acquired infection prevention. MEDUSA has achieved full authorization in both the UAE and Europe, marking a major victory in its international rollout.
Northwest Biotherapeutics (OTCQB: NWBO) is a late-stage biotechnology company focused on personalized cancer immunotherapy through its DCVax® dendritic cell vaccine platform. Its lead program, DCVax®-L for glioblastoma (GBM), has completed a 331-patient Phase III trial, with results published in JAMA Oncology and a Marketing Authorization Application currently under review in the UK. The Company is also advancing DCVax®-Direct for inoperable solid tumors, with plans to pursue Phase II trials. GBM’s orphan-disease status and the absence of effective treatments continue to position NWBO as a closely followed oncology name.
BioStem Technologies (OTC: BSEM) is focused on regenerative therapies using perinatal tissue-derived allografts processed through its proprietary BioRetain® method. The Company’s manufacturing operations are FDA-registered and AATB-accredited, with compliance across cGTP and cGMP standards. BioStem’s portfolio of placental allografts—including AmnioWrap2®, VENDAJE®, and AMERICAN AMNION®—targets wound care and regenerative applications, positioning the company within the rapidly growing regenerative medicine and biologics market.
Vivos Inc. (OTCQB: RDGL) is a clinical-stage medical device company developing RadioGel®, a precision radiotherapy hydrogel for both human and veterinary oncology. IsoPet®, its veterinary formulation, is already commercially available in certified clinics. Human therapy demonstrations in India have shown encouraging safety observations, tumor size reduction in certain cases, and no reported serious adverse events to date. Vivos is working toward anticipated regulatory clearance to expand clinical evaluations, supporting a broader regulatory and commercial pathway for targeted radionuclide therapy.
NurExone Biologic (TSXV: NRX | OTCQB: NRXBF) is a regenerative biotech company developing exosome-based therapies for central nervous system injuries. Its lead candidate, ExoPTEN, has demonstrated strong preclinical data in spinal cord and optic nerve injury models, with Orphan Drug Designation supporting the roadmap toward clinical trials in the U.S. and Europe. Recent laboratory data showed NurExone’s proprietary exosomes significantly reduced inflammatory activity compared to commercial alternatives, reinforcing the therapeutic potential of its platform as the Company advances toward first-in-human milestones.
Together, these five companies highlight the breadth of innovation occurring across the biotech and healthcare landscape—from infection prevention and oncology support to immunotherapy, regenerative medicine, and precision radiotherapy. As each advances through critical commercialization, clinical, and regulatory milestones, they are increasingly appearing on investor watchlists focused on high-impact healthcare technologies with long-term growth potential.
