Amphivena Announces New Key Leadership and Advisors – Tekla Invests in Series B Round

SOUTH SAN FRANCISCO — September 11, 2017 — Amphivena Therapeutics, Inc., a privately held biotechnology company developing a novel CD33/CD3-bispecific T cell engaging antibody for the treatment of Acute Myeloid Leukemia (AML) and Myelodysplastic Syndrome (MDS), is pleased to announce three additions to the company’s leadership team:

  • Eric J. Feldman, M.D., Senior Vice President, Clinical Development
  • Tae H. Han, Ph.D., Vice President, Clinical Pharmacology and Translational Medicine
  • Deborah J. Tranowski, Vice President, Program Management & Operations

“Amphivena’s pioneering development work on AMV564, a novel CD33/CD3-bispecific antibody for the treatment of AML and MDS, has allowed us to attract three outstanding executives who are widely regarded as leaders in their respective fields. Their decision to join Amphivena underscores our clinical achievements and AMV564’s potential as a breakthrough therapy for AML and MDS patients. The addition of these three executives also ensures that a world-class team will lead AMV564 expeditiously through the clinic,” said Jeanmarie Guenot, Ph.D., Amphivena’s co-founder, President and Chief Executive Officer.

In addition, Dr. Patrick Baeuerle joins Dr. Lori Kunkel as a clinical and scientific advisor to Amphivena. Dr. Baeuerle is a pioneer in T cell therapy and the development of bispecific T cell-engaging antibodies. At Micromet and Amgen, he invented and developed a number of T cell engagers, including BLINCYTO™ and AMG330, a CD33/CD3-bispecific BiTE™ antibody. Dr. Kunkel was Chief Medical Officer at both Pharmacyclics, Inc. and Proteolix, Inc. where she contributed to the approvals of cancer therapeutics IMBRUVICA® and KYPROLIS®, respectively. She has been an advisor to Amphivena since 2013.

Further, funds managed by Tekla Capital Management, LLC based in Boston, MA invested in Amphivena’s Series B Financing completed in July. Christian M. Richard, M.S., M.B.A., Senior Vice President, Research, joined Amphivena’s Board of Directors.

“These events mark another milestone in Amphivena’s evolution. With a very compelling preclinical profile and exciting clinical data, AMV564 has the potential to become the best-in-class T cell engaging antibody for the treatment of AML and MDS. Dr. Feldman, a world renowned leukemia expert, brings unique experience from the clinical development of three other CD33-targeting antibodies. With our newly expanded team, a new financing in place, and active strategic discussions ongoing, Amphivena is positioned to accelerate and expand the AMV564 development program,” said Luke Evnin, Ph.D. of MPM Capital, Amphivena’s co-founder and Chairman of the Board.

Amphivena is conducting a Phase 1 clinical study of AMV564 in relapsed or refractory AML. Amphivena plans to launch a Phase 1 clinical study in patients with MDS in early 2018. The company is also exploring the utility of AMV564 in solid tumors. In preclinical studies, this novel CD33/CD3 bispecific antibody demonstrated potent activity against AML patient samples that was independent of CD33 expression level, disease stage and cytogenetic risk. The antibody eliminated nearly all blasts from bone marrow and spleen in a stringent AML patient-derived xenograft murine model. In addition, Amphivena established a therapeutic window for AMV564 in cynomologus monkeys, with rapid, sustained elimination of CD33-expressing cells during AMV564 dosing and rapid hematopoietic recovery following dosing.
