  • GT Medical Technologies

    Led · Series E · Jun 2026

    GT Medical Technologies develops GammaTile, an FDA-cleared bioresorbable radiation-emitting implant placed at the time of brain tumor resection to deliver immediate, localized radiation to the surgical bed. The company highlights pivotal ROADS Phase 3 randomized controlled trial results presented at ASCO 2026 showing a 12-month surgical bed recurrence rate of 1.3% with GammaTile versus 15.4% with standard of care and improved survival outcomes. GT recently initiated the BRIDGES randomized controlled trial in newly diagnosed glioblastoma patients and plans to use proceeds from its Series E financing to expand that trial and scale commercial and operational efforts. The company was founded by a team of tumor specialists and announced the Series E from Tempe, Arizona. GT positions GammaTile as eliminating the delay between surgery and postoperative radiation by delivering immediate treatment at the resection site. The firm states the clinical data and new financing support its goal of broader adoption and further clinical development.

  • Candid Therapeutics

    Participated · Equity · Mar 2026

    Candid Therapeutics is advancing a pipeline of bispecific T-cell engager (TCE) antibodies that selectively direct T cells to eliminate disease-causing B cells and plasma cells in autoimmune disorders. Its lead candidate, cizutamig, targets BCMA and CD3 and has been administered to 87 patients (47 with autoimmune diseases), showing favorable tolerability with only mild cytokine release syndrome; Phase 2 studies in myasthenia gravis and rheumatologic interstitial lung disease are slated for 2026. Additional assets include CND261, a CD20-directed TCE already tested in over 100 patients, and CND319, a dual CD19/CD20 engager expected to enter first-in-human trials in mid-2026, plus a preclinical BCMA/CD19 program. The company is led by Chairman, President and CEO Dr. Ken Song and, following a planned merger with Rallybio, will trade on Nasdaq under the ticker CDRX. An oversubscribed private financing of more than $505 million, together with Rallybio’s cash, will leave the combined entity with roughly $700 million at closing, providing funding runway through 2030. These resources are earmarked to advance multiple clinical milestones, including the Phase 2 trials for cizutamig and early-stage studies for next-generation TCEs.
