Presents a New Phospholipid Drug Conjugate (PDC) at the 2019 AACR-NCI-EORTC Molecular Targets and Cancer Therapeutics Conference
in vivo efficacy and tolerability with a novel PDC, CLR 180099
N.J., October 30, 2019 -- 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 highlighting preclinical data with CLR 180099 at the 2019 AACR-NCI-EORTC
Molecular Targets and Cancer Therapeutics Conference, being held from October 26- 30, 2019 in Boston, MA. CLR 180099 is a
Phospholipid Drug ConjugateTM (PDC) composed of a uniquely designed phospholipid ether conjugated to a flavagline (FLV)
The poster, entitled:
"CLR 180099, a lipid raft targeted phospholipid-drug conjugate, shows potent improved safety and efficacy against colorectal
tumors," highlighted data demonstrating a greater reduction in tumor volume and improved survival with CLR 180099 than
docetaxel in a colorectal cancer model. Additionally, as compared to the FLV payload alone, the PDC demonstrated improved tolerability
with greater than a 20 fold increase in the maximum tolerated dose. CLR 180099 was also shown to have potent nanomolar activity
in other select solid tumorsincluding breast cancer and lung cancer models.
investigational program shows compelling efficacy and safety in these preclinical studies further demonstrating the versatility
and potential of PDCs as a new therapeutic class of drugs for cancer," said Jarrod Longcor, chief business officer of Cellectar.
"The ability to specifically deliver a variety of oncologic payloads to a broad range of tumor cells emphasizes the PDC technology's
unique and targeted treatment approach. These results further demonstrate this and represent another important advancement in the
development and validation of our PDC platform."
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.
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.
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.
product pipeline also includes one preclinical PDC chemotherapeutic program (CLR 1900) and several partnered PDC assets.
