WATERTOWN, Mass., September 12, 2018 --Tarveda Therapeutics, Inc., a clinical stage biopharmaceutical company discovering and developing Pentarins® as a new class of potent and selective medicines to treat a wide range of cancers, today announced the appointment of Jeffrey D. Bloss, M.D., as Chief Medical Officer. In addition, the company strengthened its clinical leadership team with the appointment of Steven A. Hamburger, Ph.D. as Vice President, Regulatory Affairs and Laura Mei as Vice President, Clinical Operations.

“We are very pleased to have Jeff join Tarveda at this exciting time for our Company. Jeff brings deep expertise and over two decades of experience leading the clinical development and medical affairs of oncology programs at both biotech and pharmaceutical companies. His track record of success, including taking numerous oncology drug programs through development and approval, will be invaluable to Tarveda as we continue to advance our two clinical stage drug programs and pipeline,” said Drew Fromkin, President and Chief Executive Officer of Tarveda. “Further, with the additions of Laura and Steve leading Clinical Operations and Regulatory Affairs, respectively, we have greatly strengthened our ability to optimize and execute the development of our two current clinical programs as well as future pipeline opportunities.”

In the second quarter of 2018, Tarveda announced the initiation of the Phase 2a expansion portion of its Phase 1/2a trial for PEN-221 in patients with somatostatin receptor 2-expressing neuroendocrine tumors and small cell lung cancer. In the same quarter, Tarveda also announced the commencement of the dose escalation portion of its Phase 1/2a trial for PEN-866 in patients with solid malignancies.

“I am pleased to join Tarveda and am impressed with the novel approach of our new class of selective and potent miniature conjugates as well as by the clinical data from our two clinical stage drug programs,” said Dr. Jeffrey Bloss. “Both PEN-221 and PEN-866 have the potential to dramatically improve the treatment of patients with solid tumors by leveraging the small size of the conjugates to rapidly penetrate deep into solid tumors while leading to the prolonged accumulation of their potent therapeutic payloads in the tumor versus healthy tissues. I am eager to advance the clinical development of both clinical stage drug programs and look forward to working side by side with Laura, Steve and the entire team to fully explore the potential of our drugs in treating patients with cancer.”

About Pentarins®
Tarveda is developing Pentarins®, potent and selective miniature drug conjugates with high affinity for specific cell surface and intracellular targets. Pentarins are engineered to bind to their tumor cell targets and provide sustained release of their potent therapeutic payloads deep into solid tumor tissue. Comprised of a targeting ligand conjugated to a potent cancer cell killing agent through a tuned chemical linker, Pentarins are designed to overcome the deficits of both larger antibody drug conjugates and small molecules that limit their therapeutic effectiveness against solid tumors. Together, the components of Tarveda’s Pentarins have distinct, yet synergistic, anticancer attributes: the small size of Pentarins allows for rapid and deep penetration into the tumor tissue, the ligand’s targeting ability allows for specific binding and retention in tumor cells, and the chemical linker is tuned to optimize the release of the potent, cell killing payload inside the cancer cells for efficacy.

About Tarveda Therapeutics, Inc.
Tarveda Therapeutics, Inc. discovers and develops Pentarins®, a new class of potent and selective miniature drug conjugates with enhanced targeting capabilities for the treatment of a wide range of solid tumor cancers. Tarveda’s lead Pentarin drug candidate, PEN-221, is a miniature drug conjugate that targets the somatostatin receptor 2 (SSTR2) for treatment of patients with neuroendocrine, small cell lung, prostate, and other cancers that express SSTR2. PEN-221 comprises a highly selective peptide for SSTR2 conjugated to the potent cytotoxic payload, DM1, through a tuned cleavable linker. Tarveda is also advancing its Pentarin HSP90 drug conjugate platform with lead drug candidate PEN-866, which is a miniature drug conjugate that selectively binds to the intracellular target, Heat Shock Protein 90 (HSP90), and is linked to the payload SN-38, a potent topoisomerase I inhibitor. Tarveda’s strategy includes developing its own proprietary Pentarins as well as applying the Pentarin platform to enhance the effectiveness of the targeting moieties and novel payloads of pharmaceutical collaborators. www.tarveda.com
