WALTHAM, Mass., May 5, 2026 /PRNewswire/ -- Q32 Bio Inc. (Nasdaq: QTTB) ("Q32 Bio"), a clinical stage biotechnology company focused on developing innovative therapies for alopecia areata (AA) and other autoimmune and inflammatory diseases, today reported financial results for the quarter ended March 31, 2026, and provided recent corporate updates.

"In the first quarter of 2026, we made meaningful strides advancing Part B of the SIGNAL-AA Phase 2 clinical trial evaluating bempikibart in patients with AA, and we remain focused on releasing 36-week topline data by mid-year. We continue to be encouraged by the profile of bempikibart in Part B based on pharmacokinetic data and clinical activity observed to-date," said Jodie Morrison, Chief Executive Officer of Q32 Bio. "There is significant demand from patients in Part B for continued dosing after the post-treatment follow-up period, and we are thrilled to announce that the first patient has been dosed in the OLE portion of Part B. Alongside this progress, we raised gross proceeds of $10.5 million through a registered direct offering and gross proceeds of $14.2 million via our ATM program, further strengthening our financial position."

First Quarter 2026 and Recent Business Highlights

• Part B of the SIGNAL-AA Phase 2a clinical trial remains on-track, with 36-week topline data readout expected in mid-2026. The Part B portion of the SIGNAL-AA Phase 2a clinical trial is an open-label clinical trial evaluating bempikibart, a fully human anti-IL-7Rα antibody designed to re-regulate adaptive immune function by blocking IL-7 and TSLP signaling, in 33 patients with severe or very severe AA with a maximum duration of current episode of four years. Total enrollment exceeded the initial target due to patient demand. Patients are treated with bempikibart for 36 weeks, with post-treatment follow-up out to 52 weeks before optional enrollment in the OLE. Dosing includes an initial loading regimen of 200mg of bempikibart dosed weekly for four doses, followed by a maintenance dose of 200mg every-other-week over a 32-week period, for a total dosing period of 36 weeks. Efficacy will be evaluated on the basis of mean percentage change from baseline in Severity of Alopecia Tool (SALT) scores, as well as the proportion of subjects achieving various relative and absolute SALT improvements at week 36, with follow-up through week 52. Encouraging signs of clinical activity are being observed in Part B of the trial. In addition, based on preliminary pharmacokinetic data available to date in the Part B portion of SIGNAL-AA, steady state concentration of drug in patients was observed at least nine weeks earlier as compared to Part A of the clinical trial due to the inclusion of the loading regimen, which may have the potential to induce earlier responsiveness. The trial is intended to support advancement into pivotal trials upon completion, pending review of the results. Q32 Bio expects to report 36-week topline results in mid-2026. After completion of the trial through 52 weeks, eligible patients can enter an open-label extension (OLE) period following the same dosing paradigm as Part B, to enable longer-term follow-up and continued data collection. The first patient has been dosed in the OLE portion of Part B.
• Part A OLE of the SIGNAL-AA Phase 2a clinical trial is complete. Based on the continued emergence of bempikibart data suggesting a remittive effect and durable responses in long-term follow-up from SIGNAL-AA Part A, as well as strong re-consent rates and patient demand for continued dosing, Q32 Bio initiated an OLE in April 2025 for eligible patients that completed Part A to enable longer-term follow-up of patients. The Part A OLE has been completed, and Q32 Bio intends to report findings from the Part A OLE with the Part B 36-week topline results in mid-2026.
• Completed $10.5 million registered direct offering . In February 2026, Q32 Bio completed a registered direct offering of 1,666,679 shares of common stock and pre-funded warrants to purchase up to 1,025,654 shares of common stock at an offering price of $3.90 per share of common stock and $3.8999 per pre-funded warrant. The gross proceeds to Q32 Bio from this offering were approximately $10.5 million, before deducting certain offering expenses of approximately $0.1 million. This transaction was led by a new institutional investor with participation by an existing dedicated public institutional investor.

Financial Results

• Cash and cash equivalents were $50.8 million as of March 31, 2026, which excludes $14.2 million in gross proceeds from sales under our at-the-market (ATM) program received after the end of the quarter. Q32 Bio believes its cash and cash equivalents as of March 31, 2026, combined with guaranteed near-term milestone payments from the ADX-097 asset sale and proceeds from sales under the ATM program after the end of the quarter, are sufficient to fund operations into the first half of 2028.
• Research and development expenses were $3.2 million for the three months ended March 31, 2026, compared to $7.1 million for the three months ended March 31, 2025. The decrease was due to lower personnel-related costs due to reduced headcount, lower bempikibart clinical expense, as well as lower ADX-097 spend due to the sale of the program in November 2025, as compared to the prior year.
• General and administrative expenses were $4.5 million for the three months ended March 31, 2026, compared to $5.1 million for the three months ended March 31, 2025. The decrease was primarily due to lower legal and consulting costs as compared to the prior year.
• Net loss was $7.6 million, or $0.54 basic and diluted net loss per share, for the three months ended March 31, 2026, compared to net loss of $11.0 million, or $0.90 basic and diluted net loss per share, for the three months ended March 31, 2025.
