ITEM 7.01 REGULATION FD DISCLOSURE
On November 12, 2018, we issued a press release announcing that on November 8, 2018, the U.S. Food and Drug Administration (FDA) has completed its initial review concerning an exemption for CLR 131 from the Import Alert placed on the Centre for Probe Development and Commercialization (CPDC), the sole supplier of our drug CLR 131. A copy of the press release is furnished as Exhibit 99.1 and is incorporated by reference herein.
ITEM 8.01 OTHER EVENTS
As described above, on November 8, 2018, the FDA notified us that it has completed its initial review concerning a possible exemption for CLR 131 from the Import Alert placed on CPDC. The FDA authorized CPDC to send shipments to the investigator sites participating in our ongoing hematology focused clinical trials, including our Phase 2 clinical study for relapsed or refractory multiple myeloma and a range of other B-cell malignancies, and our Phase 1 clinical study for relapsed or refractory multiple myeloma. As a result, the company plans to resume patient enrollment in those clinical studies.
We await authorization from the FDA for any future shipments in connection with our Phase 1 study of pediatric patients with neuroblastoma, sarcomas, lymphomas (including Hodgkin’s lymphoma) and malignant brain tumors. As a result of the supply disruption, we are experiencing delays in patient enrollment for this clinical trial.

Cellectar Announces FDA Grants Exemption to Import Alert for CLR 131 Hematology Studies
Clinical Trials to Advance Across Multiple Hematology Programs
FLORHAM PARK, N.J. (November 12, 2018) – Cellectar Biosciences, Inc. (Nasdaq: CLRB), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of drugs for the treatment of cancer, announces today 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), the sole supplier of the CLR 131. The exemption for CLR 131 is effective immediately for all hematology studies and, in response, Cellectar is preparing to dose patients in the second fractionated dose cohort of the Phase 1 relapsed refractory (R/R) multiple myeloma study and the Phase 2 study for R/R hematologic malignancies. The company awaits authorization from the FDA for any future shipments in connection with its Phase 1 study of pediatric patients with neuroblastoma, sarcomas, lymphomas (including Hodgkin’s lymphoma) and malignant brain tumors.
“We thank the FDA for their diligence and for providing this exemption for CLR 131 hematology studies. Our ability to advance our clinical trials and achieve stated business objectives remains our top priority,” said James Caruso, president and CEO of Cellectar Biosciences. “I also want to recognize our team for their outstanding execution in support of a rapid resolution.”
In its efforts to obtain an exemption for CLR 131 from the Import Alert in hematology and pediatrics, Cellectar has collaborated with the various divisions within the FDA that oversee the company’s investigational new drug applications evaluating CLR 131 in multiple indications. Cellectar executed a series of actions requested by the FDA to obtain an exemption to the Import Alert for its hematology programs. Similarly, the company continues to work with the appropriate division of the FDA to secure an exemption for the pediatric program.
As background, on August 10, 2018, Cellectar announced that CPDC was informed of an FDA Import Alert that prohibited CPDC from supplying CLR 131. While the Import Alert disrupted CLR 131 supply, the basis of the Import Alert was not related to CLR 131 specifically, or to CPDC’s production facility associated with CLR 131. The company actively supported CPDC’s efforts to have the Import Alert lifted as quickly as possible. The FDA subsequently initiated direct talks with Cellectar concerning a possible exemption for CLR 131 from the Import Alert. Those discussions and subsequent actions resulted in the exemption Cellectar is announcing today.
About CLR 131
CLR 131 is Cellectar’s investigational radioiodinated PDC therapy that exploits the tumor-targeting properties of the company's proprietary phospholipid ether (PLE) and PLE analogs to selectively deliver radiation to malignant tumor cells, thus minimizing radiation exposure to normal tissues. CLR 131 is in a Phase 2 clinical study in relapsed/refractory multiple myeloma (R/R MM) and a range of B-cell malignancies, and a Phase 1b clinical study in patients with R/R MM exploring fractionated dosing. The objective of the multicenter, open-label, Phase 1b dose-escalation study is the characterization of safety and tolerability of CLR 131 in patients with R/R MM. Patients in Cohorts 1-4 received single doses of CLR 131 ranging from 12.5 mCi/m2 to 31.25 mCi/m2 as well as a fractionated dose of 15.625 mCi/m2 given twice over seven days in Cohort 5. All study doses and regimens have been deemed safe and well tolerated by an independent Data Monitoring Committee. The company plans to initiate a Phase 1 study with CLR 131 in pediatric solid tumors and lymphoma as well as a second Phase 1 study in combination with external beam radiation for head and neck cancer.
