FLORHAM PARK, N.J., July 21, 2020 (GLOBE NEWSWIRE) — Cellectar Biosciences, Inc. (NASDAQ: CLRB), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of drugs for the treatment of cancer, today announced a poster presentation at the upcoming American Association of Cancer Research (AACR) annual meeting being held virtually on August 17-19, 2020.
A copy of the presentation materials can be accessed on the Events and Presentations section of the Cellectar website once the presentation has concluded.About CLR 131
CLR 131 is a small-molecule Phospholipid Drug Conjugate™ designed to provide targeted delivery of iodine-131 (radioisotope) directly to cancer cells, while limiting exposure to healthy cells unlike many traditional on-market treatment options. CLR 131 is the company’s lead product candidate and is currently being evaluated in a Phase 2 study in B-cell lymphomas, and a Phase 1 dose-escalating clinical study in pediatric solid tumors and lymphomas. The company recently completed a Phase 1 dose-escalation clinical study in r/r multiple myeloma. The FDA granted CLR 131 Fast Track Designation for both r/r multiple myeloma and r/r diffuse large b-cell lymphoma and Orphan Drug Designation (ODD) for the treatment of multiple myeloma, lymphoplasmacytic lymphoma/Waldenstrom’s macroglobulinemia, neuroblastoma, rhabdomyosarcoma, Ewing’s sarcoma and osteosarcoma. CLR 131 was also granted Rare Pediatric Disease Designations for the treatment of neuroblastoma, rhabdomyosarcoma, Ewing’s sarcoma and osteosarcoma. Most recently, the European Commission granted an ODD for r/r multiple myeloma.About the Phase 2 CLOVER-1 Study
CLOVER-1 is a Phase 2 study of CLR 131 being conducted in 10 leading cancer centers in the United States in patients with relapsed/refractory B-cell hematologic cancers. The hematologic cancers studied include multiple myeloma (MM), chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), lymphoplasmacytic lymphoma/ Waldenstrom’s macroglobulinemia (LPL/WM), marginal zone lymphoma (MZL), mantle cell lymphoma (MCL), and diffuse large B-cell lymphoma (DLBCL).The study can enroll up to 80 patients with its primary endpoint being clinical benefit response (CBR), which is defined as the proportion of MM patients following infusion of CLR 131 with stringent complete response, complete response, very good partial response, partial response and stable disease per International Myeloma Working Group criteria, or the proportion of lymphomas patients (CLL/SLL, LPL, MZL, MCL, and DLBCL) following infusion of CLR 131 with CR, PR and SD per the Lugano classification CT-based response criteria or International Waldenstrom’s Macroglobulinemia Society criteria or the International Chronic Lymphocytic Leukemia criteria. Additional endpoints include overall response rate (ORR), progression free survival (PFS), median overall survival (OS) and other markers of efficacy. Patients were treated with three different doses (<60mCi single cycle, >60mCi single cycle and >60 mCi multi-cycle total body dose).The CLOVER-1 Phase 2 study completed the Part A dose-exploration portion conducted in relapsed/refractory (r/r) B-cell malignancies and is now enrolling in the Part B expansion cohorts in relapsed/refractory (r/r) multiple myeloma (MM) and lymphoplasmacytic lymphoma/Waldenstrom’s macroglobulinemia (LPL/WM). Part B is evaluating the two cycle dosing of CLR 131 in additional patients. Each cycle is defined as two doses provided 14 days apart (+/- 1 day). Cycle 2 shall be given 8-weeks post the initial infusion. Additional cycles can be considered following an additional 8-week period. The Part A portion of the study met its primary and secondary endpoints with detailed data being announced on February 19, 2020.Cellectar was awarded approximately $2 million in non-dilutive grant funding from the National Cancer Institute to help fund the study. More information about the study, including eligibility requirements, can be found at www.clinicaltrials.gov, reference NCT02952508.About Cellectar Biosciences, Inc.
Cellectar Biosciences is focused on the discovery, development and commercialization of drugs for the treatment of cancer. The company is developing proprietary drugs independently and through research and development collaborations. The company’s core objective is to leverage its proprietary Phospholipid Drug Conjugate™ (PDC) delivery platform to develop PDCs that specifically target cancer cells, delivering improved efficacy and better safety as a result of fewer off-target effects. The company’s PDC platform possesses the potential for the discovery and development of the next-generation of cancer-targeting treatments, and it plans to develop PDCs independently and through research and development collaborations.The company’s lead PDC therapeutic, CLR 131, is currently in two clinical studies. The CLOVER-1 Phase 2 study completed the Part A dose-exploration portion, conducted in relapsed/refractory (r/r) B-cell malignancies, and is now enrolling in the Part B expansion cohorts evaluating a two cycle dosing regimen that provides approximately 100mCi total body dose of CLR 131 in relapsed/refractory (r/r) multiple myeloma (MM) and lymphoplasmacytic lymphoma/Waldenstrom’s macroglobulinemia (LPL/WM). The data from the Part A portion was announced on February 19, 2020. The company is also conducting a two-part Phase 1 dose-escalation with expansion arms in pediatric solid tumors and lymphomas.The company’s product pipeline includes one preclinical PDC chemotherapeutic program (CLR 1900) and multiple partnered PDC assets.For more information, please visit www.cellectar.com or join the conversation by liking and following us on the company’s social media channels: Twitter, LinkedIn, and Facebook.Forward-Looking Statement Disclaimer
