On November 12, 2018 Cellectar Biosciences, Inc. (Nasdaq: CLRB), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of drugs for the treatment of cancer, reported that the U.S. Food and Drug Administration (FDA) has granted an exemption to the Import Alert placed on the Centre for Probe Development and Commercialization (CPDC), the sole supplier of the CLR 131 (Press release, Cellectar Biosciences, NOV 12, 2018, View Source [SID1234531227]). The exemption for CLR 131 is effective immediately for all hematology studies and, in response, Cellectar is preparing to dose patients in the second fractionated dose cohort of the Phase 1 relapsed refractory (R/R) multiple myeloma study and the Phase 2 study for R/R hematologic malignancies. The company awaits authorization from the FDA for any future shipments in connection with its Phase 1 study of pediatric patients with neuroblastoma, sarcomas, lymphomas (including Hodgkin’s lymphoma) and malignant brain tumors.

"We thank the FDA for their diligence and for providing this exemption for CLR 131 hematology studies. Our ability to advance our clinical trials and achieve stated business objectives remains our top priority," said James Caruso, president and CEO of Cellectar Biosciences. "I also want to recognize our team for their outstanding execution in support of a rapid resolution."

In its efforts to obtain an exemption for CLR 131 from the Import Alert in hematology and pediatrics, Cellectar has collaborated with the various divisions within the FDA that oversee the company’s investigational new drug applications evaluating CLR 131 in multiple indications. Cellectar executed a series of actions requested by the FDA to obtain an exemption to the Import Alert for its hematology programs. Similarly, the company continues to work with the appropriate division of the FDA to secure an exemption for the pediatric program.

As background, on August 10, 2018, Cellectar announced that CPDC was informed of an FDA Import Alert that prohibited CPDC from supplying CLR 131. While the Import Alert disrupted CLR 131 supply, the basis of the Import Alert was not related to CLR 131 specifically, or to CPDC’s production facility associated with CLR 131. The company actively supported CPDC’s efforts to have the Import Alert lifted as quickly as possible. The FDA subsequently initiated direct talks with Cellectar concerning a possible exemption for CLR 131 from the Import Alert. Those discussions and subsequent actions resulted in the exemption Cellectar is announcing today.

About CLR 131

CLR 131 is Cellectar’s investigational radioiodinated PDC therapy that exploits the tumor-targeting properties of the company’s proprietary phospholipid ether (PLE) and PLE analogs to selectively deliver radiation to malignant tumor cells, thus minimizing radiation exposure to normal tissues. CLR 131 is in a Phase 2 clinical study in relapsed/refractory multiple myeloma (R/R MM) and a range of B-cell malignancies, and a Phase 1b clinical study in patients with R/R MM exploring fractionated dosing. The objective of the multicenter, open-label, Phase 1b dose-escalation study is the characterization of safety and tolerability of CLR 131 in patients with R/R MM. Patients in Cohorts 1-4 received single doses of CLR 131 ranging from 12.5 mCi/m2 to 31.25 mCi/m2 as well as a fractionated dose of 15.625 mCi/m2 given twice over seven days in Cohort 5. All study doses and regimens have been deemed safe and well tolerated by an independent Data Monitoring Committee. The company plans to initiate a Phase 1 study with CLR 131 in pediatric solid tumors and lymphoma as well as a second Phase 1 study in combination with external beam radiation for head and neck cancer.

On November 11, 2018 Harpoon Therapeutics, Inc. ("Harpoon"), a clinical-stage immunotherapy company developing a novel class of T cell engagers, reported the closing of a $70 million Series C equity financing (Press release, Harpoon Therapeutics, NOV 11, 2018, View Source [SID1234531110]). OrbiMed served as the lead new investor, along with new investors Cormorant, Ridgeback Capital Investments, Lilly Asia Ventures (LAV) and NS Investment. Harpoon’s existing investors MPM Capital, Oncology Impact Fund, Arix Bioscience, New Leaf Venture Partners and Taiho Ventures, LLC also participated in the Series C financing round. Harpoon intends to use the proceeds from the financing to support further advancement of its immunotherapy programs based on its TriTAC (Tri-specific T cell Activating Construct) and ProTriTAC (Protease-activated Tri-specific T Cell Activating Construct) platforms, which are designed to harness the natural power of the body’s immune system to fight cancer and other diseases.

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 Generon’s second bispecific antibody in clinical development.

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.
