The data presented will describe the safety, tolerability, pharmacokinetics, and preliminary efficacy of PEN-221, a miniature drug conjugate containing a peptide ligand that is highly selective in targeting the somatostatin receptor 2 (SSTR2) that is conjugated to the potent payload DM1. SSTR2 is a cell surface target that is overexpressed in a variety of solid tumor cancers. PEN-221 is currently being evaluated in a Phase 2a trial in patients with gastrointestinal midgut neuroendocrine tumors, pancreatic neuroendocrine tumors, or small cell lung cancer.
"We are very pleased to have completed the Phase 1 portion of our Phase 1/2a clinical trial for PEN-221 on schedule and to present the data from the Phase 1 trial evaluating PEN-221 at ASCO (Free ASCO Whitepaper)," said Drew Fromkin, President and Chief Executive Officer of Tarveda. "We are encouraged by the data from studies of PEN-221 to date and look forward to advancing the Phase 2a portion of the study for PEN-221 as well as our Phase 1 trial for PEN-866."
Details of the poster presentation are as follows:
Title: First in human phase 1/2a study of PEN-221 somatostatin analog (SSA)-DM1 conjugate for patients (PTS) with advanced neuroendocrine tumor (NET) or small cell lung cancer (SCLC): Phase 1 results.

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.
