2 May 2023 — Malmö, Sweden — Ascelia Pharma, a biotech focused on improving the life of people living with rare cancer conditions, today announced that liver imaging drug candidate, Orviglance, significantly improved visualisation of focal liver lesions, successfully meeting the primary endpoint in the pivotal phase 3 study SPARKLE. Investors and analysts are invited to the virtual Investor Update: “Bringing Orviglance to Patients”, on 7 May at 14:00 CEST.

  • The phase 3 study demonstrated strong superiority in visualisation of focal liver lesions with Orviglance (CMRI) vs unenhanced MRI with statistical significance for all three readers (<0.001)
  • Orviglance is in development as a first-in-class contrast agent for use in liver MRI in patients with severely impaired kidney function and has been granted FDA Orphan Drug Designation
  • Orviglance addresses a global $800m market annually
  • The phase 3 data marks the completion of Orviglance clinical development with nine studies in 286 patients and healthy volunteers
  • Submission of the New Drug Application (NDA) file to the US Food and Drug Administration (FDA) is expected by mid-2025
  • Investors, analysts and media are invited to the virtual Investor Update and live Q&A on next steps: “Bringing Orviglance to Patients”, on 7 May 2024 at 14:00 CEST.

The pivotal phase 3 study, SPARKLE, successfully met the primary endpoint and demonstrated that the
company’s magnetic resonance imaging (MRI) contrast agent, Orviglance significantly improved the
visualisation of focal liver lesions compared to unenhanced MRI. The results for all three readers were
highly statistically significant (P values <0.001).

The reliability of the data is strong and conclusive for all readers – this includes an acceptable level of
variability.

Common adverse events in this vulnerable patient population were in line with previous studies with
Orviglance, such as mild to moderate nausea. No serious adverse drug reactions were observed.

“We are thrilled to announce these strong and convincing phase 3 results for Orviglance. This is the
most significant milestone achievement for Ascelia Pharma so far,” said Magnus Corfitzen, CEO of
Ascelia Pharma. “Following considerable challenges during the SPARKLE study, we are very excited to
complete the Orviglance clinical development with these strong results in phase 3. We now look forward
to advancing Orviglance through the registration process and make it available for patients.”

The company will now focus on bringing Orviglance through the regulatory submission and approval
process. In parallel, we will continue to advance launch readiness and dialogue with potential
commercialisation partners to make Orviglance available to patients who need high-quality liver
imaging without gadolinium-related safety risk.

“On behalf of the entire Ascelia Pharma team, I would like to thank patients and investigators involved
in the SPARKLE study, as well as other partners instrumental in completing the successful data read-out.
We look forward to discussing the results with the medical community and regulatory authorities,” said
Magnus Corfitzen.

The Company expects to submit the New Drug Application (NDA) file to the US FDA by mid-2025 to obtain regulatory approval.

Investors, analysts and media are invited to the virtual Investor Update: “Bringing Orviglance to
Patients”, on 7 May 2024 at 14:00 CEST. In this update and live Q&A, executive management
will further explain the strong headline results and share plans for the upcoming regulatory and
commercialisation activities.

Clinical development of Orviglance has now been completed with consistent positive efficacy and safety
data from 286 patients and healthy volunteers in nine studies, of which the SPARKLE is the last and
pivotal study. Patient enrolment in the global multi-centre SPARKLE study was completed early 2023,
with MRI data from 85 patients with known or suspected focal liver lesions and severely impaired
kidney function. In accordance with regulatory requirements, the improvement of visualisation of
lesions was evaluated by three independent radiologist readers. In mid-2023, the unexpected discovery
of high intra-reader variability in the study image scoring by the readers prevented the company from
evaluating the efficacy data from SPARKLE. Therefore, a new evaluation of the images with new readers
was required. The company successfully completed the re-evaluation according to the planned timeline
with the announcement today.

Orviglance has been granted an Orphan Drug Designation by the FDA for liver MRI in patients with severely impaired kidney function. These patients have the highest risk of developing the serious and potentially fatal condition Nephrogenic Systemic Fibrosis (NSF) after exposure to the currently available gadolinium-based contrast agents. Regulatory bodies have issued warnings for the use of these agents in this vulnerable patient population. Therefore, there is a need for an alternative solution to detect and visualise focal liver lesions in patients with impaired kidney function, who today typically receive inferior unenhanced MRI. Liver MRI is a cornerstone in cancer care, as liver metastases are common in many cancer types and often the cause of mortality. Orviglance aims to give patients with impaired kidney function access to safe and effective liver imaging to live longer and healthier lives. The unmet need for these patients represents an addressable market potential of $800m globally.
