Efficacy established in 4th class of molecules utilizing Phospholipid Ether Vehicle
FLORHAM PARK, N.J., Dec. 13, 2019 (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 Jarrod Longcor, chief business officer of Cellectar, presented a poster at the AACR San Antonio Breast Cancer Symposium in San Antonio, TX.
The poster, entitled: “Preclinical evaluation of a novel phospholipid drug conjugate, CLR 2000045 with a combretastatin A-4 analogue for improved breast cancer therapy,” featured data demonstrating potent in vivo activity in multiple animal models of breast cancer, including a model of triple negative breast cancer. Multiple doses of CLR 2000045 resulted in a statistically significant reduction in tumor volume (p<0.05 and 0.01 respectively) and survival (p<0.05 and 0.001 respectively) in the HCC70, triple negative breast cancer model as compared to vehicle control. In a separate study, the compound displayed comparable activity to paclitaxel in an initial screening model of metastatic breast cancer and the data showed that all doses of CLR 2000045 were well tolerated in both models.
“The data further demonstrate that PDCs are an exciting and novel class of targeted oncology agents with potential in a wide variety of tumor types,” said Jarrod Longcor, chief business officer of Cellectar. “We have validated targeted delivery to tumor cells and shown efficacy in multiple cancer types utilizing our phospholipid ether delivery vehicle with four separate classes of molecules. These data demonstrate the unique potential of our novel cancer targeting platform.”
About Phospholipid Drug Conjugates™
Cellectar’s product candidates are built upon a patented delivery and retention platform that utilizes optimized phospholipid ether-drug conjugates (PDCs™) to target cancer cells. The PDC platform selectively delivers diverse oncologic payloads to cancerous cells and cancer stem cells, including hematologic cancers and solid tumors. This selective delivery allows the payloads’ therapeutic window to be modified, which may maintain or enhance drug potency while reducing the number and severity of adverse events. This platform takes advantage of a metabolic pathway utilized by all tumor cell types in all cell cycle stages. Compared with other targeted delivery platforms, the PDC platform’s mechanism of entry does not rely upon specific cell surface epitopes or antigens. In addition, PDCs can be conjugated to molecules in numerous ways, thereby increasing the types of molecules selectively delivered. Cellectar believes the PDC platform holds potential for the discovery and development of the next generation of cancer-targeting agents.
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 (R&D) collaborations. The company’s core objective is to leverage its proprietary Phospholipid Drug ConjugateTM (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 three clinical studies – a Phase 2 study, and two Phase 1 studies. The Phase 2 clinical study (CLOVER-1) is in relapsed/refractory (R/R) B-cell malignancies, including multiple myeloma (MM), chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), lymphoplasmacytic lymphoma (LPL), marginal zone lymphoma (MZL), mantle cell lymphoma (MCL), and diffuse large B-cell lymphoma (DLBCL). The company is also conducting a Phase 1 dose escalation study in patients with R/R multiple myeloma (MM) and a Phase 1 study in pediatric solid tumors and lymphoma.
The company’s product pipeline also includes one preclinical PDC chemotherapeutic program (CLR 1900) and several partnered PDC assets.
