  • The result from first patient dosed with VMT-α-NET in India on a compassionate use basis showed favorable responses.
  • The initial response was measured by a somatostatin imaging agent 68Ga-DOTANOC and demonstrated surprisingly favorable results after a single low dose of 212Pb-VMT-a-NET.

RICHLAND, WASHINGTON & CORALVILLE, IOWA – February 22, 2023  Perspective, Therapeutics, Inc. (formerly known as “Isoray, Inc.”) (NYSE AMERICAN: CATX), a precision oncology company developing alpha-particle therapies and complementary diagnostic imaging agents and an innovator in seed brachytherapy powering expanding treatment options for multiple cancers, announced the presentation of extremely encouraging results regarding 212Pb-VMT-α-NET, its lead preclinical candidate for neuroendocrine tumors (NET), currently being used therapeutically in India on a compassionate use basis. Dr Vikas Prasad presented the results at the 2023 PET Radiotracer Translation and Resource Center (PET-RTRC) Workshops & Scientific Session hosted by the Mallinckrodt Institute of Radiology (MIR) at Washington University in St. Louis.

Highlights of the presented results include:

  • The result from first patient dosed with 212Pb-VMT-α-NET in India on a compassionate use basis showed favorable responses after the first dose.
  • The initial response was measured by a somatostatin imaging agent 68Ga-DOTANOC and demonstrated encouraging results after a single low dose of 212Pb-VMT-α-NET.

Dr. Prasad noted, “The patient data gathered in the clinic under a compassionate use basis is not only remarkable but an extremely encouraging sign for Perspective Therapeutics’ VMT-α-NET program for the treatment of neuroendocrine tumors. Despite advancement in traditional therapies, novel approaches and therapies are required to further increase patients’ overall survival and improve quality of life. There is an urgent need of bringing these kind of therapies in the first line of management of functionally active neuroendocrine tumors.”

Dr. Vikas Prasad, MD, who is an Associate Professor of Radiology, Mallinckrodt Institute of Radiology (MIR), Washington University School of Medicine in St. Louis, presented the 212Pb- VMT-α-NET results. Prior to MIR, Dr. Prasad subsequently performed the first human images of 203Pb-VMT-α-NET while serving as MD, Vice Chair in the Department of Nuclear Medicine at the University Hospital of Ulm, Ulm, Germany.

“We are grateful that the science and medicine that is in development at Perspective Therapeutics has provided a meaningful intervention in a NET patient’s care journey. The results give us hope that we are standing at the beginning of a new era of precision oncology medicine. We look forward to continuing the progress of our pipeline of targeted radiopharmaceuticals for imaging and therapeutic use,” said Mr. Thijs Spoor, CEO of Perspective Therapeutics.

VMT-α-NET is being developed for the treatment and diagnosis of somatostatin receptor subtype 2 (SSTR2) expressing neuroendocrine tumors, which are a rare and difficult-to-treat type of cancer. The dosed patients were diagnosed with confirmed-advanced somatostatin expressing neuroendocrine tumors (NETs). In early December, VMT-α-NET, the Company’s lead drug for the treatment of neuroendocrine tumors was administered to patients in India on a compassionate use basis, independent of a planned U.S. trial. No acute adverse reactions were observed post administration and patients remained stable and in good condition.

The administration of VMT-α-NET was performed under the supervision of the patients’ doctor, Dr. Ishita Sen MBBS, DRM, DNB, Director and Head of Nuclear Medicine at Fortis Hospital, New Delhi, in partnership with BJ Madan, a diagnostic & therapeutic radiopharmaceutical company in New Delhi. Radiopharmaceutical was produced (under the direction of Dr. Sen) by Dr. Parul Thakral Dash PhD and administered following appropriate quality control testing. Patients were imaged immediately prior to their first therapeutic dose and immediately prior to the second therapeutic dose. The results seen between the 1st and 2nd doses implied that the patients had a strongly favorable response which was unexpected at such low doses of the drug. Dr. Sen expressed her pleasure at the patients’ progress and said, “Preclinical and clinical data associated with this new radiopharmaceutical demonstrates significant potential to help our NET patients.”

Under compassionate use circumstances, VMT-α-NET may be made available to qualified doctors in some countries. In this circumstance, Perspective Therapeutics (formerly Viewpoint Molecular Targeting, Inc.) supplied drug precursors and isotopes for the local production of its proprietary radiotherapeutic, VMT-α-NET. The safety and effectiveness of the treatments will be evaluated by Dr. Sen’s team with laboratory testing, observation of NET-associated symptoms, and repeat medical imaging.

In the U.S., VMT-α-NET will soon enter a Phase 1 imaging and therapy study to be conducted at various hospitals and clinics. The administration of VMT-α-NET for compassionate use is completely independent from and not within the scope of the Company’s Phase 1 trial.

In this circumstance, Viewpoint supplied drug precursors and isotopes for the local production of its proprietary radiotherapeutic, VMT-α-NET.
