Periodic Reporting for period 9 - CUCUMBER (Bringing to market the world’s first integrated medical cooling system for minimizing brain damage in stroke patients.)

Okres sprawozdawczy: 2024-12-01 do 2025-05-31

Podsumowanie kontekstu i ogólnych celów projektu

CLINICAL:
Significant progress was made during this period, focusing on the initiation of the COTTIS-2 trial and site activation. Challenges included site activation, protocol deviations, and contract finalization. By July, Freiburg was ready, with the first patient treated using RhinoChill® and BrainCool™ Systems. Recruitment progressed, reaching 13 patients by December. Gießen and Erlangen were activated in November, with recruitment starting in December and January, respectively. An investigator meeting on September 25 in Frankfurt addressed protocol updates, logistics, training, and device distribution. Attendees included key investigators, CRO monitors, and BrainCool representatives.

TECHNICAL:
BrainCool identified defects in systems from Innokas and developed protocols for inspecting and releasing incoming goods for clinical studies. Catheter testing revealed performance discrepancies, leading to the establishment of inspection protocols to meet performance criteria. Discussions with SHL and Innokas are ongoing, with SHL initiating tooling setup for increased catheter production.

DEVIATION:
Several factors, including the need for a safety trial (COTTIS-1), contract changes, ethics amendments, and a sponsor change, caused delays. Three centers are now active, with a fourth (Essen) starting by January’s end. To establish this innovative cooling treatment for severe stroke patients, an 18-month project extension to November 2026 is requested without additional budget or costs.

Innowacyjność oraz oczekiwany potencjalny wpływ (w tym dotychczasowe znaczenie społeczno-gospodarcze i szersze implikacje społeczne projektu)

Stroke is the most common cause of disability in Europe and was estimated to cost healthcare over €45 billion in 2020, a cost that is expected to increase by nearly 44% until 2040, according to the European stroke organization Stroke Alliance for Europe (SAFE). The COTTIS-1 study confirms the neuroprotective properties of very early hypothermia combined with thrombectomy as 95% of the penumbra tissues were salvaged by this approach. 64% of patients are within 0-2 on the mRS scale already at discharge from the hospital (approx. 8-9 days after treatment), and 68% at 3 months. Retrospective studies of treated normothermic patients with thrombectomy at the University Hospital of Freiburg show a result of only 32-42% (mRS 0-2), and metaanalysis of randomized trials reported independency after 3 months (mRS 0-2) of 46%. Health economics data available show the influence of patient’s degree of neurological disability on the overall costs that will be incurred in the following years. Publications show that the mean 5-year cumulative costs differed significantly according to the 3-month mRS score; the costs for a 3-month mRS score of 0 or 5 were $53,578 and $257,486 USD, respectively. Three-month mRS score was an independent determinant of long-term costs after stroke. Therefore, it is expected that RhinoChill can significantly reduce the cost of stroke for patients and society.
