Blue Earth Diagnostics announces FDA filing of Supplemental New Drug Application (sNDA) for Axumin PET imaging in Glioma

December 11, 2018
December 10, 2018 -- BURLINGTON, Mass. & OXFORD, England--(BUSINESS WIRE)--Blue Earth Diagnostics, a molecular imaging diagnostics company, today announced that the U.S. Food and Drug Administration (FDA) has accepted for review a supplemental New Drug Application (sNDA) for the expanded use of Axumin® (fluciclovine F 18) in adults for the detection and continuing assessment of glioma.

Fluciclovine is a synthetic amino acid labeled with the radioisotope F 18, enabling PET imaging to visualize the increased amino acid transport that occurs in malignant tumors such as glioma, which is a serious and life-threatening condition accounting for about 80% of all malignant brain tumors.

18F-Fluciclovine, under the tradename Axumin® (fluciclovine F 18) injection, is FDA-approved for use in positron emission tomography (PET) imaging in men with suspected prostate cancer recurrence based on elevated blood levels of prostate specific antigen (PSA) following prior treatment. 18F-Fluciclovine PET imaging is being investigated for the detection and continuing assessment of glioma. (For additional product information please see the end of this news release.) 18F-Fluciclovine has previously been granted Orphan Drug status by both the FDA and the European Medicines Agency for the diagnosis of glioma.

"We are very pleased that the FDA has accepted for review our sNDA submission for the use of 18F-fluciclovine PET imaging in glioma," said Jonathan Allis, D. Phil., CEO of Blue Earth Diagnostics. "Expanding the label for Axumin is part of our mission to develop and commercialize innovative PET imaging products that address unmet medical needs for patients with cancer."

"Glioma is the twelfth leading cause of death from cancer, and certain aggressive forms of the disease, such as glioblastoma multiforme, can progress rapidly," said Peter Gardiner, MB ChB, MRCP, FFPM, CMO of Blue Earth Diagnostics. "Physicians need precise information about the location and extent of the tumor to help guide surgical procedures and radiation therapy, as well as for subsequent continued assessment and monitoring of the disease. We are exploring the potential utility of 18F-fluciclovine PET to assist them in these efforts."

Blue Earth Diagnostics recently announced results from one of the Phase 3 clinical trials supporting the sNDA submission to the FDA at the Society for Neuro-Oncology annual meeting in November 2018. The study, BED006, was a prospective, blinded image evaluation that examined the diagnostic performance of 18F-fluciclovine PET imaging, in conjunction with various types of MRI, for imaging of suspected glioma when interpreted by readers unfamiliar with 18F-fluciclovine PET. Results indicated a Positive Predictive Value (PPV) of more than 90% for each of the three blinded readers and consistent image interpretation across these readers. In addition, 18F-fluciclovine PET with MRI (CE-T1W MRI) identified additional regions suspicious for glioma that MRI alone was unable to identify, which subsequent biopsies confirmed as malignant. To date, the safety profile of 18F-fluciclovine PET imaging in patients with glioma appears to be consistent with that summarized in the current Axumin U.S. prescribing information.


About 18F-fluciclovine PET in Glioma
18F-Fluciclovine PET is a diagnostic imaging radiopharmaceutical for PET imaging that consists of a synthetic amino acid labeled with the radioisotope F 18, enabling the visualization of the increased amino acid transport that occurs in malignant tumors. 18F-Fluciclovine, under the trade name Axumin®, is approved by the U.S. Food and Drug Administration (FDA) for PET imaging in men with recurrent prostate cancer. The clinical trial program to support the safety and efficacy, in terms of diagnostic performance, of 18F-fluciclovine PET imaging in adults for the detection and continuing assessment of glioma encompasses four trials conducted in Japan by Nihon Medi-Physics Co., Ltd and two studies in Europe and the United States by Blue Earth Diagnostics. To date, the safety profile of 18F-fluciclovine PET imaging in patients with glioma appears to be consistent with that summarized in the current Axumin prescribing information. 18F-Fluciclovine has been granted Orphan Drug status by both the FDA and the European Medicines Agency for the diagnosis of glioma. The compound was invented at Emory University in Atlanta, Ga., with much of the fundamental clinical development work carried out by physicians at Emory University's Department of Radiology and Imaging Sciences.


About Glioma
Glioma, the most commonly occurring type of primary brain tumor, is a serious and life-threatening condition. Cancer of the brain and central nervous system (CNS) is the twelfth most common cause of cancer death worldwide. Glioma accounts for about 25% of all brain tumors, and 80% of all malignant brain tumors. The most aggressive form of glioma, glioblastoma multiforme, is associated with significant morbidity and mortality with relatively low 5-year survival estimates after diagnosis. Current treatment options for patients with glioma include surgery, radiation and chemotherapy. Accurate evaluation of the location and extent of a glioma tumor is essential before or during surgery and radiotherapy and in assessing the continuing status of the disease. The detection and assessment of gliomas typically involves magnetic resonance imaging (MRI), which may be complemented by metabolic imaging using an appropriate amino acid-based PET radiopharmaceutical as recommended in the Response Assessment in Neuro-Oncology (RANO) working group and European Association for Neuro-Oncology (EANO) guidelines.1
