Q32 Bio Announces Bempikibart Clinical Trial Results

Q32 Bio announced 36-week topline results from Part B of the SIGNAL-AA Phase 2a clinical trial evaluating bempikibart in patients with severe or very severe AA. Bempikibart is a fully human anti-IL-7Ralpha antibody designed to re-regulate adaptive immune function by blocking IL-7 and TSLP signaling. The Part B portion of the SIGNAL-AA program is an open-label clinical trial building upon the previously completed Part A, which established proof-of-concept of bempikibart in AA. In Part B, bempikibart is being evaluated in 33 patients with severe or very severe AA with a maximum duration of current episode of four years. Enrollment amongst patients with prior exposure to JAK inhibitor therapy were allowed; amongst the 33 enrolled patients, 36.4% had previously been treated with oral JAK inhibitors. Total enrollment exceeded the initial target due to patient demand. In Part B, patients are treated with bempikibart for 36 weeks, with off-drug follow-up through Week 52 before optional enrollment in the open-label extension. Dosing includes an initial loading regimen of 200mg of bempikibart dosed weekly for four doses, followed by continued dosing of 200mg every-other-week over a 32-week period, for a total dosing period of 36 weeks. Across both regimens, bempikibart was administered subcutaneously. The prespecified primary efficacy analysis was evaluated on the basis of mean percentage change from baseline in SALT scores in the modified intent-to-treat population. Additional prespecified efficacy analyses included the proportion of patients achieving various relative and absolute SALT improvements including SALT-20, SALT30, and SALT50 responses at Week 36, with follow-up through Week 52. Mean percent reduction in SALT score from baseline of 35.3% in the mITT analysis. Overall, 40% of patients in the mITT analysis and 30.3% of patients in the intent-to-treat analysis achieved a SALT-20 response. Achievement of a SALT-20 response was observed in patients with both severe and very severe disease. Also, 44% of patients in the mITT analysis and 33.3% of patients in the ITT analysis achieved SALT30 response. While 44% of patients in the mITT and 33.3% of patients in the ITT analysis achieved SALT50 response. Early signs of durability in the off-drug period include maintenance or deepening of response in multiple patients including one who achieved complete hair growth. Bempikibart was observed to have a generally well-tolerated safety profile in SIGNAL-AA Part B, consistent with prior studies. No new safety signals were observed. There were no serious adverse events or Grade 3 or higher adverse events related to treatment. The most common treatment-emergent adverse event was injection site reaction which were primarily singular events, with ISR incidence of 4% across all Part B dose administrations. All ISRs reported were mild and resolved with no intervention, with the majority resolving within a day. Bempikibart demonstrated a favorable pharmacokinetic, pharmacodynamic and anti-drug antibody profile in Part B. PK data from Part B support the loading dose regimen had its intended effect, achieving steady state concentrations approximately 10 weeks earlier than in Part A. Negligible ADA was observed in Part B.
