Preclinical evaluation of SPK-8011QQ, an adeno-associated virus gene therapy for people with hemophilia A leveraging the dirloctocogene samoparvovec platform encoding an activated Protein C-resistant B-domain deleted factor VIII (ASH 2025) - "Surrogate SPK-8011QQ, which leverages the previously clinically evaluated SPK-8011(dirloctocogene samoparvovec) platform to introduce FVIII-QQ, demonstrates markedly enhancedhemostatic potency under APC-sensitive conditions in ex vivo and in vivo mouse models. Furthering thelearnings from the safety and durability of the SPK-8011 platform, our preclinical data collected to datesupport the ongoing evaluation of SPK-8011QQ, which aims to optimize FVIII potency and hemostaticpotential."

Haemophilia A (Roche Press Release) - "Hemlibra (emicizumab): New post-marketing data from the Beyond ABR study show that, in the first year after switching to Hemlibra prophylaxis from factor VIII prophylaxis, people with various levels of baseline joint impairment had low bleeding rates, associated with overall improvements in joint health, and a shift towards higher activity levels...NXT007: Positive phase I/II results, including new data from a global study in people with haemophilia A with and without factor VIII inhibitors....SPK-8011QQ: Pre-clinical data on Roche’s next-generation investigational AAV gene therapy, show significantly enhanced haemostatic potency compared with SPK-8011 (dirloctocogene samoparvovec) in ex vivo and in vivo mouse models. Findings support the ongoing evaluation of SPK-8011QQ, furthering previous learnings on the safety and durability of SPK-8011, with phase IIb study initiation planned for 2026."
