Fourth Quarter and Recent Corporate Highlights
·Announced CLR 131 achieved primary efficacy endpoints from its Phase 2 CLOVER-1 study in relapsed/refractory B-cell lymphomas and completion of the Phase 1 relapsed/refractory multiple myeloma Dose Escalation study. The data showed:
o42.8% overall response rate (ORR) in median 6th line treatment of multiple myeloma at the 75mCi total body dose
o81.8% of the multiple myeloma patients across all therapeutic doses tested experienced tumor reduction with a strong dose response
o100% ORR and 25% complete response (CR) seen in lymphoplasmacytic lymphoma/Waldenstrom’s macroglobulinemia (LPL/WM) patients
o42.0% ORR and 11% CR in all non-Hodgkin’s lymphoma (NHL) patients
·Received Orphan Drug Designation for CLR 131 in lymphoplasmacytic lymphoma (LPL) from the U.S. Food and Drug Administration
·Oral presentation at the American Society of Hematology (ASH) (Free ASH Whitepaper) Conference entitled "Fractionated Dosing of CLR 131 in Patients with Relapsed or Refractory Multiple Myeloma"
·Oral presentation at the European Society of Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress entitled "Interim Evaluation of a Targeted Radiotherapeutic, CLR 131, in Relapsed/Refractory Diffuse Large B-cell Lymphoma Patients"
·Scientific conference poster presentations during the quarter included:
oAmerican Association for Cancer Research (AACR) (Free AACR Whitepaper) San Antonio Breast Cancer Symposium entitled "Phospholipid ether delivery vehicle shows specificity for a broad range of tumor cells and provides a novel and improved approach for targeted therapy"
oAACR-NCI-EORTC Molecular Targets and Cancer Therapeutics Conference entitled "CLR 180099, a lipid raft targeted phospholipid-drug conjugate, shows potent improved safety and efficacy against colorectal tumors"
oUK-AACR Joint Conference on Engineering and Physical Sciences in Oncology entitled "Preclinical evaluation of a novel phospholipid drug conjugate, CLR 2000045 with a combretastatin A-4 analogue for improved breast cancer therapy"
·Strengthened the management team with the appointment of Dr. Igor Grachev, Chief Medical Officer
"Data from our CLR 131 Phase 1 dose escalation study and the Phase 2 CLOVER-1 study demonstrated a unique safety profile and an encouraging response rate of nearly 43% as a sixth-line treatment for relapsed/refractory multiple myeloma," said James Caruso, President and CEO of Cellectar. "Importantly, the 75mCi dose demonstrated excellent activity in very challenging to treat subpopulations, high-risk, triple class refractory and penta-refractory. We plan to enroll additional patients at 100mCi of CLR 131 in the two-cycle dosing optimization regimen, which we believe will further increase response rates, the durability of responses and will likely be used in our pivotal study planned for initiation in Q4 of this year."
2019 Financial Highlights
Cash and Cash Equivalents: As of December 31, 2019, the company had cash, cash equivalents and restricted cash of $10.6 million compared to $13.3 million at December 31, 2018. Cash provided by financing activities was $9.0 million, offset by cash used in operating activities of $11.7 million. Consistent with prior guidance, the company believes its cash on hand is adequate to fund operations into the first quarter of 2021.
Research and Development Expense: Research and development expense for the year ended December 31, 2019 was $9.0 million, compared to $6.8 million for the year ended December 31, 2018. The overall increase in research and development expense of approximately 32% was primarily attributable to an increase in clinical project costs largely related to the startup of the pediatric study, as well as an increase in patient recruitment for the ongoing clinical studies.
General and Administrative Expense: General and administrative expense for the year ended December 31, 2019 was $5.2 million, compared to $4.8 million for the year ended December 31, 2018. The increase of 8% in general and administrative costs was primarily related to an increase in personnel and consulting costs and an increase related to public company expenses, rent and depreciation. These costs were offset by a decrease in accounting fees and restructuring charges.
Net Loss: The net loss attributable to common stockholders for the year ended December 31, 2019 was ($14.1) million, or ($1.84) per share, compared to ($15.5) million, or ($5.23) per share, in 2018.
