Søren Tulstrup, President and CEO of Hansa Biopharma, comments

"I am very pleased with the strong commercial performance in the first quarter of 2024, the second consecutive quarter with solid product sales and a promising start to 2024. This strong sales performance is a continuation of the traction we saw at the end of last year where key large markets such as UK and Germany started to contribute.  Our performance continues to be driven by our largest markets underpinned by new and repeat use of IDEFIRIX at leading transplant centers. We have now achieved pricing and reimbursement in 75% of the European kidney transplant market and expect to see utilization in new centers resulting in additional sales growth in 2024.

Our clinical programs in kidney transplantation continue to progress at pace. Enrolment and randomization in our pivotal US Phase 3 trial (ConfIdeS) is advancing as expected. During the first quarter of 2024 four new sites have been activated and both screening and randomization of eligible patients have recently accelerated. We expect randomization to complete in mid-2024, as previously guided.

We have also made significant progress in the European post approval study - PAES - with more than a doubling of the number of patients treated in the trial in the last couple of quarters. This post approval study is an obligation under the European conditional marketing authorization and will be used to further investigate the long-term graft survival in 50 highly sensitized kidney transplant patients treated with IDEFIRIX. The study will also help generate important clinical experience in leading transplant centers in using IDEFIRIX as a new transformative desensitization therapy in highly sensitized patients.

Beyond kidney transplantation, we continue to advance our imlifidase clinical programs in autoimmunity. In the Phase 3 trial in anti-GBM disease, our lead autoimmune indication, we have reached 50% enrolment in the trial and expect completion in 2025 as previously guided.  We also expect to share contextualized efficacy data later this year in our 15-HMedIdeS-09 Phase 2 study in Guillain-Barré Syndrome (GBS). This follows promising first high-level data shared in December 2023.

On April 12, 2024, we announced that additional financing had been secured - extending our cash runway into 2026 through a SEK ~372m (USD ~34.6m) directed share issue targeting mainly U.S. and European healthcare specialist investors. I am very pleased to see the strong interest in the Hansa equity story from leading international health specialist investors. This transaction will help finance the preparation of a potential U.S. launch of imlifidase in kidney transplantation, strengthen ongoing product development in autoimmune indications and allow for the continued clinical development of HNSA-5487, the lead candidate from the NiceR program for repeat dosing.

Lastly, I am delighted to welcome Evan Ballantyne as Chief Financial Officer. With his deep international experience and successful track record as a CFO at public and private life science companies I am confident that Evan will be a strong addition to our team and will help drive our financial strategy, deliver on key strategic priorities, and build shareholder value.

We look forward to keeping you updated on our continued progress, with several upcoming important milestones to be achieved across our platform and franchises as we continue the development of new, transformative medicines for patients suffering from serious, rare immunologic diseases."
