The TCR specific for the minor histocompatibility antigen HA-1 was developed by LUMC and tested for preliminary safety and tolerability in a Phase I clinical trial involving five patients. HA-1 is a well-characterized antigen expressed in cells of the hematopoietic system, in leukemia and lymphoma cells, as well as expressed in various solid tumors.

Dr Kai Pinkernell, CMO and CDO of Medigene , said: "We are excited to have licensed this HA-1-targeting T cell receptor, which has already undergone early clinical testing, to complement Medigene’s preclinical and clinical development program. Scientists from LUMC and Medigene have had a longstanding shared scientific interest and exchange on HA-1 and we look forward to our future interactions. Our own extensive research and development for the HA-1 antigen confirms the potential of this approach in general and this TCR candidate in particular. Its potential applicability in both liquid and solid tumors makes strategic sense within our growing internal pipeline."

Mirjam H.M. Heemskerk, PhD, Associate Professor of the Department of Hematology at the Leiden University Medical Center , said: "Medigene is an ideal partner to further advance this promising TCR candidate given their deep scientific expertise, broad development work and strong focus on TCRs. We share a common vision of developing T cell receptor therapies to offer seriously ill cancer patients much-needed treatment alternatives."

Under the terms of the agreement, Medigene will receive the exclusive worldwide development and commercialization rights to the HA-1-specific TCR developed by LUMC. In return, LUMC will receive a one-time payment along with certain milestone payments. Upon commercialization, LUMC is eligible for royalties in the low-single digit percentage range. Confidentiality was agreed regarding further financial details.

Terms of the deal do not materially impact Medigene’s financial guidance for the balance of the year 2018.

About HA-1: The HA-1 antigen has been extensively studied by Medigene’s research team. It is a clinically validated T cell target used in stem cell transplantation (SCT). HA-1, as a single nucleotide polymorphism (SNP), is easily detected by a PCR method and shows a well-characterized tissue expression pattern.

Harpoon’s TriTAC platform was designed to advance the therapeutic potential of T cell engagers, with a long half-life extended format. Harpoon is developing a pipeline of four wholly owned TriTAC product candidates. Harpoon’s lead product candidate, HPN424, is currently in a Phase 1 clinical trial for the treatment of metastatic castration-resistant prostate cancer, or mCRPC.

"This financing is a significant milestone for us as we continue to advance our pipeline, including HPN424, our lead product candidate, with which we initiated a Phase 1 trial this summer as a potential treatment for prostate cancer," said Jerry McMahon, Ph.D., President and Chief Executive Officer. "With these funds, we intend to pursue preclinical and clinical development of additional product candidates based on our TriTAC platform as well as our second technology platform, ProTriTAC, which we believe can expand access to a broader landscape of tumor targets and indications."

"Harpoon has assembled a world-class team to drive forward an ambitious pipeline across a range of indications and patient populations," said Luke Evnin, Ph.D., Co-Founder and Chairman of Harpoon and Founder and Managing Director at MPM Capital. "With this financing, we believe we have the capacity not only to advance those pipeline programs but also to continue to innovate in the immuno-oncology arena."

In addition, in 2019, Harpoon plans to initiate Phase 1 clinical trials for HPN536 (a mesothelin-targeting TriTAC) for the treatment of mesothelin-expressing tumors, and HPN217 (a BCMA-targeting TriTAC) for the treatment of multiple myeloma. The ProTriTAC platform effort is yielding T-cell engagers against additional targets based on tumor protease-dependent activation in the tumor microenvironment, and Harpoon expects to advance its first ProTriTAC product candidate to IND-enabling studies in 2019.

On November 11, 2018 Generon Corporation, a leading biopharmaceutical company in China, reported it received approval for the Company’s Investigational New Drug (IND) application from the State Food and Drug Administration (SFDA) of the People’s Republic of China to initiate a Phase I clinical trial for A-319 in patients with B cell malignancies (Press release, Generon (Shanghai), NOV 11, 2018, View Source [SID1234531111]).

A-319 is the first CD19 engaging bispecific antibody approved by the SFDA for clinical trials in China. The CD3/CD19 bispecific antibody was developed using Generon’s Immuno-Therapy Antibody (ITab)TM technology platform. The IND approval enables Generon to commence Phase I clinical trials in China enrolling patients with B cell malignancies including acute lymphoblastic leukemia (ALL) and B cell lymphoma.

Dr. Mi Jian Qing, Professor at Ruijin Hospital, Shanghai Jiaotong University expressed his enthusiasm about the biology of A-319 and the potential benefits for ALL patients. He commented: "Obtaining the SFDA’s approval for the A-319 Phase I trial is a significant accomplishment for Generon’s ITabTM platform. The IND approval is another step in demonstrating Generon’s innovative capabilities".

Yifan Pharmaceuticals, Generon’s parent company, congratulated Generon’s team on the continued effort to develop innovative therapies. Dr. Xiao Qiang Yan, CEO and CSO of Generon, said, "Initiation of a Phase I study for A-319 in China is one of Generon’s goals this year. A-319 has a similar mechanism of action to eliminate malignant B cells to those of CAR-T and other CD19/CD3 bispecific antibodies, but it is more convenient for patient dosing and potentially with better safety. A-319 is our second T-cell activating bispecific antibody to enter clinical development. Generon is expanding its ITabTM pipeline for both liquid and solid tumors and committed to bringing innovative immune-oncology antibodies to cancer patients in China and the world".

B cell malignancies

B cell malignancies refer to the different types of cancers that form in B cells in the immune system, including B-cell lymphomas and B-cell leukemia. B-cell lymphoma may be either indolent (slow-growing) or aggressive (fast-growing). Most B-cell lymphomas are non-Hodgkin lymphomas (NHL). There are many different types of B-cell non-Hodgkin lymphomas including chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), Burkitt lymphoma (BL), diffuse large B-cell lymphoma (DLBL), follicular lymphoma (FL), and mantle cell lymphoma (MCL). B-cell leukemia includes B-cell chronic lymphocytic leukemia (CLL), Acute lymphoblastic leukemia (ALL), B-cell prolymphocytic leukemia (PLL), and hairy cell leukemia (HCL). The prognosis and treatment of B cell malignancies depend on the specific type of the B cell lymphoma/leukemia, as well as the stage and grade. Recent immunotherapy (T-cell activating) approaches have demonstrated significant clinical benefits for patients.

About A-319

A-319 is a T-cell activating bispecific antibody (BsAb) designed to target CD19 and CD3 (anti-CD19, anti-CD3) and is under development for the treatment of patients with B cell malignancies including B-cell leukemia and B-cell lymphoma. A-319 activates T lymphocytes in a patient to kill CD19 expressing malignant B-cells.
