Q: How should we think about the cadence of development milestones within the CSL collaboration, and are there updates on the flu vaccine program and a potential combo program with COVID flu? A: Joseph Payne, President and CEO, stated that CSL is providing guidance for the flu program, having completed Phase 1 for the quadrivalent version. CSL holds a global license for the flu program and will provide updates on further developments. Andrew Sassine, CFO, added that Arcturus will continue to receive milestones from CSL throughout the year, with more details to be provided in the first quarter call.
Q: How should we think about potential differentiation from competitors in the CF program, especially within the mRNA space? A: Joseph Payne explained that Arcturus differentiates itself through its proprietary mRNA molecule, LUNAR lipid nanoparticle delivery technology, and unique manufacturing and purification processes. These differences have been demonstrated in preclinical animal studies and early human clinical trials.
Q: Could you provide details on the CF interim data expected in Q2, including the size of the cohort and what you hope to show? A: Joseph Payne mentioned that the Phase 2 trial involves approximately 12 participants, with flexibility to increase that number. The interim update will include multiple patients and dose levels. An FEV lung function improvement of 3% would likely justify advancing ARCT-032 further into development, based on historical precedents in the CFTR modulator space.
Q: Can you comment on how enrollment for the CF program has been progressing and the anticipated split of Class I and CFTR intolerable patients? A: Joseph Payne stated that enrollment is on track, with multiple active sites. The CF community includes approximately 18% who do not respond to modulators, with about half being Class I null patients. The trial aims to address the unmet medical need across all genetic variations.
Q: What are the next steps towards commercialization of KOSTAIVE in the EU, and how will orders be managed? A: Andrew Sassine noted that CSL is leading the commercialization process in Europe, leveraging their experience in the flu program. The $28 million reported was Arcturus' share of gross profit from sales, contributing to recouping development costs. The cash runway is expected to extend until the end of Q1 2027, without relying on KOSTAIVE revenue.
