Safety Review Committee Approves the Continued Evaluation of the 20 MBq/kg Betalutin® with 100 mg/m2 Lilotomab Regimen in Phase 2 Cohort in NHL

OSLO, Norway, May 19, 2017 /PRNewswire/ --

Press Release no: 15/2017

Nordic Nanovector ASA (OSE: NANO) announces that the Safety Review Committee (SRC) for the ongoing LYMRIT 37-01 clinical trial of Betalutin® in non-Hodgkin's Lymphoma (NHL) has reviewed safety data from the study and approved continued clinical evaluation of 20 MBq/kg Betalutin® administered after pre-dosing with 100 mg/m2 lilotomab.

Following the SRC's recommendation, new patients will be enrolled into a Phase 2 expansion cohort of Arm 4 in Betalutin's Phase 1/2 study LYMRIT 37-01, to continue the collection of safety and efficacy data of 20 MBq/kg Betalutin® after pre-dosing with 100 mg/m2 lilotomab. This will enable the company to build a robust database of clinical data to confirm the optimal dosing regimen for the pivotal Phase 2 PARADIGME study, which is on track to start in the second half of 2017.

Luigi Costa, Nordic Nanovector CEO, said: "This recommendation from the SRC represents another important milestone for the development of Betalutin®, in line with our strategy and established timelines. It supports the hypothesis that a higher pre-dosing regimen may enable the use of a higher dose of Betalutin®. The enrolment of new patients in Phase 2 provides the opportunity to collect additional safety and preliminary efficacy data to support the selection of the dosing regimen we will use in PARADIGME later this year."

About LYMRIT 37-01

The LYMRIT 37-01 study is an ongoing Phase 1/2 open label, dose-escalation study with four treatment arms in patients with relapsed NHL to establish the recommended dosing regimen of single-dose Betalutin® for Phase 2. The study is investigating three doses of Betalutin® and different pre-dosing regimens with the aim of identifying an optimal dose regimen to take into a pivotal Phase 2 PARADIGME trial.

The most recent results were presented at the American Society of Hematology (ASH) annual meeting in December 2016 and showed:

• Significant anti-tumour activity observed: ORR of 62%, CR 38% in Arm 1 patients receiving 15MBq/kg; consistent for 16 patients treated in Arm 1/Phase 2 (ORR 69%, CR 38%)

• Durable responses observed: median duration of response of 20.7 months for patients in Arm 1

• Well tolerated with a predictable and manageable safety profile

Updated results from LYMRIT 37-01 have been accepted for presentation at the International Conference on Malignant Lymphoma (ICML), June 14-17 in Lugano, Switzerland.
