FLORHAM PARK, N.J., Aug. 12, 2019 (GLOBE NEWSWIRE) -- Cellectar Biosciences, Inc. (CLRB), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of drugs for the treatment of cancer, today announced financial results for the second quarter ended June 30, 2019, and provided a corporate update.
“We made considerable progress on both the clinical and regulatory fronts during the second quarter and subsequent period. CLR 131 continues to advance, delivering encouraging preliminary data with improving efficacy and a clear dose response in our ongoing Phase 1 study. In addition, the company received FDA Fast Track Designation for CLR 131 in two separate indications and believe that we continue to track toward a registrational study in at least one B-cell hematologic malignancy from our ongoing Phase 2 CLOVER-1 study,” said Jim Caruso, CEO of Cellectar. “Our recently adopted fractionated dosing schedule of CLR 131 has led to the improved efficacy and tolerability observed in our latest cohorts and we are moving forward with this dosing strategy in our recently initiated pediatric Phase 1 trial for the treatment of life-threatening cancers.”
Second Quarter and Recent Corporate Highlights
Announced initial results from Cohort 6 in the company’s ongoing Phase 1 clinical study with CLR 131 in Relapsed or Refractory Multiple Myeloma (R/R MM). Data from Cohort 6 showed improved efficacy and a clear dose response compared to prior cohorts, including a 50% overall response rate, a 50% minimal response rate and 100% disease control rate. The International Myeloma Working Group defines a partial response as a 50% to 89.9% reduction in the marker of disease and minimal response as 25% to 49.9% reduction in the marker of disease. One patient achieved a minimal response with a 48% reduction in their m-protein. The other patient achieving a minimal response had a 39% reduction in m-protein remains on study and continues to be evaluated.
Expanded the third cohort of our ongoing Phase 2 CLOVER-1 study of CLR 131 after preliminary results showed it exceeded pre-specified performance criteria. We are currently enrolling patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), lymphoplasmacytic lymphoma (LPL) and marginal zone lymphoma (MZL) in the third cohort. The company continues to expect to report top-line data from the Phase 2 CLOVER-1 study in 2019.
Received FDA Fast Track Designation for CLR 131 in two separate indications: in fourth line or later relapsed/refractory multiple myeloma and in relapsed or refractory Diffuse Large B-Cell Lymphoma (DLBCL). CLR 131 is currently being evaluated in Cellectar’s ongoing CLOVER-1 Phase 2 clinical study in patients with select B-Cell lymphomas, including multiple myeloma and DLBCL.
Closed on a financing for gross proceeds of $10 million. In a registered direct offering, Cellectar issued 1,982,000 shares of common stock. In a separate concurrent private placement transaction, Cellectar sold 2,018,000 shares of common stock. In conjunction with the offerings, the company also issued 4,000,000 warrants to purchase common stock in the private placement.
