FLORHAM PARK, N.J., May 04, 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 first quarter ended March 31, 2023 and provided a corporate update.

First Quarter and Recent Corporate Highlights

• Presented at both the Roth Capital Partners 35^th Annual Conference on March 13, 2023, and the Oppenheimer 33^rd Annual Healthcare Conference on March 14, 2023. A replay of the Oppenheimer presentation is available on the Events Page of the Company’s IR website.
  

“We maintained strong operational momentum in the first quarter, with our primary focus being the execution of our pivotal trial of iopofosine in Waldenstrom’s macroblobulinemia (WM). In parallel with study enrollment and anticipated conclusion, we continue to prepare for the commercial launch of iopofosine.” said James Caruso, president and CEO of Cellectar. “At the same time, we are advancing other key programs for iopofosine and are encouraged by the data observed, some of which we presented at recent scientific conferences. We remain pleased with the depth of our clinical program and collectively believe 2023 will be a very meaningful year for us as we look forward to key data announcements including topline data from our WM pivotal study.”

First Quarter 2023 Financial Highlights

• Cash and Cash Equivalents: As of March 31, 2023, the company had cash and cash equivalents of $12.7 million, compared to $19.9 million as of December 31, 2022. Net cash used in operating activities during the three months ended March 31, 2023 was approximately $7.2 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 three months ended March 31, 2023 was approximately $6.7 million, compared to approximately $3.9 million for the three months ended March 31, 2022. The overall increase in research and development expense was driven by increased clinical, manufacturing and related costs.
  
  

• General and Administrative Expense: G&A expense for the three months ended March 31, 2023 was $2.1 million, compared to $2.3 million for the same period in 2022. The overall decrease in G&A costs was primarily driven by a decrease in professional fees, partially offset by increased personnel costs.

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.
