TRex Bio And Retension Set IPO Plans As 2026 Biotech Listings Keep Building

TRex would use IPO proceeds to move a Treg-focused autoimmune pipeline forward, while Retension is centered on taking RTN-001 through a phase 2b study and into phase 3 in uncontrolled hypertension. The paired filings suggest the current IPO window is open to very different biotech profiles, as long as the use of capital is tightly linked to near-term development steps.

The New York-based firm said LumaBio Fund I is designed to support companies from discovery through commercialization.

Encoded Raises $275 Million For ETX101 And Manufacturing, Advancing Dravet Gene Therapy Push

The financing backs both late-development execution and infrastructure, with Encoded pairing a registration-directed program in Dravet syndrome with a commercial manufacturing build-out. That combination signals that investors are still willing to fund genetic medicines when companies can point to clinical traction and a clearer path toward control of supply.

Solstice Raises $225 Million Series A, Moving Porustobart Into Phase 2 In MSS Colon Cancer

Solstice was founded in February and quickly licensed porustobart from Harbour BioMed for development and commercialization outside of China under a deal that included a $105 million upfront package. Its financing now funds a phase 2 trial in a patient population the company says has yet to benefit from immunotherapy, with enrollment due to begin this year or in the fourth quarter depending on the source and data expected in the second half of 2027.

The round adds to a $57 million seed launch in early 2024 and highlights continued investor interest in differentiated metabolic programs despite a market dominated by GLP-1 drugs.

BrainChild Bio Raises $116 Million Series A, Funding BCB-276 Toward A 75-Patient DIPG Study

The financing gives the Seattle Children’s Hospital spinout enough capital to continue its lead effort in diffuse intrinsic pontine glioma, or DIPG, where BrainChild is running an open-label, single-arm phase 2 study of BCB-276. Across the available reporting, the raise is described as $116 million by Fierce Biotech and $119 million by BioSpace, a discrepancy the company’s sourced coverage does not resolve.
