Cellectar Biosciences

FLORHAM PARK, N.J., March 09, 2023 (GLOBE NEWSWIRE) -- Cellectar Biosciences, Inc. (NASDAQ: CLRB), a late-stage biopharmaceutical company focused on the discovery, development and commercialization of targeted treatments for cancer, today announced financial results for the year ended December 31, 2022 and provided a corporate update.

Fourth Quarter and Recent Corporate Highlights

• Presented preclinical data on the CLR 12120 series of targeted alpha therapies (TATs) at the 13^th Annual World ADC Conference. The presentation, entitled: “Novel Conjugates – Radiotherapies,” given by Cellectar’s Chief Operating Officer, Jarrod Longcor, highlighted data demonstrating the versatility of the phospholipid ether (PLE) targeting platform and the potential of the company’s alpha emitting precision medicines, supporting further development.
  
  

• Announced that Cellectar, the Wisconsin Alumni Research Foundation, and Drs. Jamey Weichert and Anatoly Pinchuk have resolved a lawsuit filed by Cellectar in October 2021 in the United States District Court for the Western District of Wisconsin concerning employee contracts and intellectual property rights in certain intellectual property pertaining to the diagnosis and treatment of cancer. The parties cannot further comment on that resolution, except to note that (i) all claims against Drs. Weichert and Pinchuk have been voluntarily dismissed, and (ii) Cellectar has secured an irrevocable, non-exclusive license to the patents at issue in the lawsuit.
  
  

• Announced Shane Lea as chief commercial officer, overseeing all marketing and commercialization efforts for Cellectar as it prepares for data from its pivotal trial in Waldenstrom’s macroglobulinemia.
  
  

• Appointed Dr. Andrei Shustov as senior vice president, medical to lead and provide oversight on all aspects of the Company’s clinical development program, medical affairs, and medical communications.
  
  

• Announced that a patient with primary central nervous system lymphoma enrolled in its Phase 2 CLOVER-1 Trial demonstrated a complete response according to the 2005 Response Criteria for CNS Lymphoma with total resolution of the tumor on imaging studies.
  

“2022 was highly productive for Cellectar. We currently have 43 global sites actively recruiting patients for our pivotal study in Waldenstrom’s macroglobulinemia (WM). In parallel, our technology demonstrated consistently positive outcomes across multiple indications. At the American Society of Hematology Conference, we presented a 50% response rate achieved by iopofosine in post BCMA multiple myeloma patients and successfully concluded our phase 1a pediatric study and will initiate a phase 1b for High Grade Gliomas supported by a $2 million NCI grant. We also reported the extraordinary complete response in a patient with relapsed/refractory CNS lymphoma further demonstrating iopofosine’s ability to cross the blood/brain barrier and target cancer,” said James Caruso, president and CEO of Cellectar. “Importantly, we strengthened our commercial leadership with several key hires, including Shane Lea, who has launched six new hematology/oncology products, and Dr. Andrei Shustov, who provides a wealth of hematology/oncology clinical as well as study experience.”

Fourth Quarter 2022 Financial Highlights

• Cash and Cash Equivalents: As of December 31, 2022, the company had cash and cash equivalents of $19.9 million, compared to $35.7 million as of December 31, 2021. Net cash used in operating activities during the year ended December 31, 2022 was approximately $25.2 million. The company believes its cash on hand is adequate to fund budgeted operations into the fourth quarter of 2023.
  
  

• Research and Development Expense: R&D expense for the year ended December 31, 2022 was approximately $19.2 million, compared to approximately $17.6 million for the year ended December 31, 2021. The overall increase in research and development expense was primarily a result of an increase in manufacturing and costs related to production sourcing and pre-clinical costs.
  
  

• General and Administrative Expense: G&A expense for the year ended December 31, 2022 was $9.5 million, compared to $6.5 million for the same period in 2021. The increase in G&A costs was primarily a result of increased professional fees, a portion of which were non-recurring, as well as travel and personnel costs.
  
  

• Net Loss: The net loss attributable to common stockholders for the year ended December 31, 2022 was ($28.6) million, or ($4.05) per share, compared to ($24.1) million, or ($4.35) per share, in the year ended December 31, 2021.
  

About Cellectar Biosciences, Inc.
Cellectar Biosciences is focused on the discovery and development 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 to deliver 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 product pipeline includes iopofosine, a small-molecule PDC designed to provide targeted delivery of iodine-131 (radioisotope), proprietary preclinical PDC chemotherapeutic programs and multiple partnered PDC assets. The company is currently investigating iopofosine in a global, open-label, pivotal expansion cohort in relapsed or refractory WM patients who have received at least two prior lines of therapy, including those who have failed or had a suboptimal response to Bruton tyrosine kinase inhibitors. The WM cohort will enroll up to 50 patients to evaluate the efficacy and safety of iopofosine for marketing approval. The company is also evaluating iopofosine in highly refractory multiple myeloma patients in its Phase 2 CLOVER-1 study and relapsed/refractory pediatric cancer patients with sarcomas or brain tumors in the Phase 1 CLOVER-2 study.

The Phase 1 pediatric study is an open-label, sequential-group, dose-escalation study to evaluate the safety and tolerability of iopofosine in children and adolescents with relapsed or refractory cancers, including malignant brain tumors, neuroblastoma, sarcomas, and lymphomas (including Hodgkin’s lymphoma). The Phase 1 study is being conducted internationally at seven leading pediatric cancer centers.

The company has established exclusivity on a broad U.S. and international intellectual property rights portfolio around its proprietary cancer-targeting PLE technology platform, including iopofosine and its PDC programs.

In addition to the company’s exclusivity to iopofosine and its phospholipid ethers conjugated to small molecules, peptides, and oligos, the company now has non-exclusive rights to the use of the phospholipid ether platform when conjugating with a chelator to bind select metal radioisotopes.
