In February 2019, we announced that a single, 25mCi/m2, 30-minute intravenous infusion of CLR 131 in the first 10 patients with R/R MM were assessed. We are currently enrolling patients in our Phase 1 and Phase 2 multiple myeloma and select B-cell lymphoma studies of CLR 131.

FDA Grants Exemption to Import Alert for Cellectar’s CLR 131 in Pediatric and Adolescent Patients

 

Company to initiate Phase 1 study in pediatric and adolescent patients with select relapsed or
refractory solid tumors, lymphomas and malignant brain tumors

 

FLORHAM PARK, N.J., Mar. 19, 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 that the U.S. Food and Drug Administration (FDA) has granted an exemption to the Import Alert placed on the Centre for Probe Development and Commercialization (CPDC) for the use of CLR 131 in connection with the company’s pediatric IND. This exemption will allow Cellectar to immediately begin enrolling patients in its Phase 1 pediatric study for the treatment of select relapsed or refractory solid tumors including neuroblastoma, lymphomas and malignant brain tumors.

 

Cellectar is already enrolling patients in its Phase 1 and Phase 2 multiple myeloma and select B-cell lymphoma studies of CLR 131 after having received FDA exemption to the CPDC Import Alert in November 2018 for its hematology IND.

 

“We are grateful that the FDA has granted this additional exemption for CLR 131, which allows us to immediately initiate our pediatric clinical study in children battling life-threatening cancers,” said James Caruso, president and CEO of Cellectar. “These patients have a very poor prognosis and low rates of survival as a result of limited effective treatment options. Based on our preclinical and ongoing clinical studies, we are optimistic that CLR 131 has the potential to provide a meaningful treatment option for children suffering from cancers with high unmet medical needs.”

 

About the Phase 1 Pediatric Study of CLR 131

The Phase 1 pediatric study will be an open-label, sequential-group, dose-escalation study to evaluate the safety and tolerability of a single intravenous administration of CLR 131 in up to 30 children and adolescents with cancers, including neuroblastoma, sarcomas, lymphomas (including Hodgkin’s lymphoma) and malignant brain tumors. Secondary objectives of the study are to identify the recommended Phase 2 dose of CLR 131 and to determine preliminary antitumor activity (treatment response) of CLR 131 in children and adolescents. We plan to initiate this Phase 1 study at 5-7 pediatric cancer centers, within and possibly outside the US.

 

About CLR 131

CLR 131 is a small-molecule, cancer-targeting radiotherapeutic PDC designed to deliver cytotoxic radiation directly and selectively to cancer cells and cancer stem cells. CLR 131 is our lead therapeutic PDC product candidate and is currently being evaluated in both Phase 2 and Phase 1 clinical studies. In December 2014, the FDA granted orphan drug designation for CLR 131 for the treatment of multiple myeloma. In 2018, the FDA granted orphan drug and rare pediatric disease designations for CLR 131 for the treatment of neuroblastoma, rhabdomyosarcoma, Ewing’s sarcoma and osteosarcoma. The FDA previously accepted our IND application for a Phase 1 open-label, dose-escalating study to evaluate the safety and tolerability of a single intravenous administration of CLR 131 in up to 30 children and adolescents with cancers including neuroblastoma, sarcomas, lymphomas (including Hodgkin’s lymphoma) and malignant brain tumors.
