CAMBRIDGE, Mass.; OSLO, Norway; LONDON, UK, and BASEL, Switzerland - June 21, 2023 – ARTBIO, Inc. (ARTBIO), a clinical-stage radiopharmaceutical company developing a new class of targeted alpha radioligand therapies (ART), announced its founding with a $23 million seed financing led by F-Prime Capital with Omega Funds. ARTBIO was founded in 2021 by Roy Larsen, Øyvind Bruland, Radforsk, and F-Prime Capital to create highly targeted cancer therapies by pairing the optimal alpha-emitting isotope Pb212 with ligands against proven tumor-specific targets. ARTBIO is also creating an entirely new approach to ART manufacturing to overcome production and distribution challenges. In early 2022, Emanuele Ostuni, formerly Head of Europe for Cell and Gene Therapy at Novartis Oncology, joined ARTBIO as CEO to start building its world-class team and advance its proprietary technology, while securing additional funding from F-Prime Capital and Omega Funds.

The financing enables ARTBIO’s ongoing clinical development of its lead program AB001 for the treatment of prostate cancer. The funds will enable the company to advance a differentiated pipeline, further develop its AlphaDirect^TM Pb212 isolation technology, and expand its distributed manufacturing network.

“Our unique approach combines Pb212 best in class properties with rationally designed ligands against tumor-specific targets to unlock the full therapeutic potential of alpha radioligand therapy,” said Emanuele Ostuni, Ph.D., Chief Executive Officer of ARTBIO. “Many cancer patients still have few or no treatment options. We focus on ARTs with Pb212 because they can selectively deliver lethal energy to tumors in an optimal timeframe, resulting in better outcomes for patients and easier management by health care professionals. We are equally focused on building a distributed manufacturing ecosystem to maximize the potential of these therapies through a footprint tailored to the short half-life of Pb212.”

A New Approach for Alpha Radioligand Therapy (ART)

ARTBIO’s unique approach is underpinned by a deep understanding of cancer biology and the infrastructure needed to effectively design, manufacture and distribute ARTs.

There are four distinct pillars of development:

The ideal alpha-emitter profile: Pb212 has a short half-life that matches the properties of the small molecule carriers used by ARTBIO, delivering most of its energy into the tumor quickly.
A differentiated pipeline of ARTs: ARTBIO has one asset in clinical development, with additional assets in rapid pre-clinical development, each focusing on addressing unmet medical needs.
Distributed ART manufacturing ecosystem: The company is building an end-to-end distributed manufacturing network for reliable and fast delivery of therapeutic candidates to the bedside.
Proprietary Pb212 isolation technology: ARTBIO’s AlphaDirect^TM technology delivers highly pure Pb212 from widely available raw materials.

An Expert Leadership Team

ARTBIO has assembled a world-class team of talented professionals spanning multiple disciplines and categories.

“ARTBIO’s team is highly skilled and passionate, bringing together a unique combination of expertise in the radioligand space, drug development and oncology,” said Ted W. Love, M.D., Chairman of the Board at ARTBIO. “I believe that ARTBIO’s approach represents the future of radioligand therapy that will radically advance cancer care.”
