Our portfolio company Nordic Nanovector ASA presented updated results from its LYMRIT 37-01 Phase 1/2 clinical study of Betalutin® (177Lu-satetraxetan-lilotomab) in patients with relapsed/refractory (R/R) indolent NHL (iNHL) at the 59th Annual ASH meeting.
The updated data continue to highlight Betalutin®’s strong clinical profile as a single agent for treatment of R/R iNHL, and particularly of third-line R/R follicular lymphoma (3L FL), the primary patient population for which Betalutin® is initially being developed.
Single-agent Betalutin® is effective and well-tolerated in patients with R/R iNHL:
· 90% of all patients (n=59) had a reduction in tumour size
· Overall response rate (ORR) of 60% and complete response (CR) of 24% for all evaluable iNHL patients
· Highly active in patients with 2 or more prior therapies (3L FL) with 66% ORR and 25% CR
· Encouraging results in FL patients:
o Arm 1 40/15: 68% ORR and 28% CR
o Arm 4 100/20: 50% ORR and 25% CR
· Durable responses, especially for patients with a CR
o 13.3 months for all iNHL patients
▪ 20.5 months for patients with CR
o 13.3 months for FL patients treated with 40 mg lilotomab/15 MBq/kg Betalutin®
▪ 22.9 months for patients with CR
As reported previously, Betalutin® treatment was well-tolerated with a safety profile characterized by reversible transient neutropenia and thrombocytopenia and a low incidence of infections.
Dr Arne Kolstad, MD, Principal Investigator of the study, commented: “The data presented at ASH are very exciting. The combination of efficacy, tolerability and the convenience of a single administration highlight Betalutin®’s potential in this primarily elderly, heavily pre-treated patient population. Notably, the CRs seen in both Arm 1 and Arm 4 in FL patients and the duration of responses are very promising, and we look forward to treating more patients in the upcoming PARADIGME study.
Dr Lisa Rojkjaer, Chief Medical Officer of Nordic Nanovector, added: “We are very pleased about these data, which continue to demonstrate a strong clinical profile for Betalutin®, particularly in 3L FL patients. The CR rates are especially encouraging. This is a population of high unmet medical need for whom safe effective therapies are needed, and the Phase 2b PARADIGME trial will focus on these patients. The results obtained provide a strong foundation for this trial.”

About Nordic Nanovector:
Nordic Nanovector is committed to develop and deliver innovative therapies to patients to address major unmet medical needs and advance cancer care. The Company aspires to become a leader in the development of targeted therapies for haematological cancers. Nordic Nanovector’s lead clinical-stage candidate is Betalutin®, a novel CD37-targeting Antibody-Radionuclide-Conjugates (ARC) designed to advance the treatment of non-Hodgkin’s Lymphoma (NHL).
NHL is an indication with substantial unmet medical need, representing a growing market forecast to be worth nearly USD 20 billion by 2024. The Company aims to rapidly develop Betalutin®, alone and in combination with other therapies, for the treatment of major types of NHL, targeting first regulatory submission in relapsed/refractory follicular lymphoma in 2019. Nordic Nanovector intends to retain marketing rights and to actively participate in the commercialisation of Betalutin® in core markets.
The Company is also advancing a pipeline of ARCs and other immunotherapies for multiple cancer indications. Further information about the Company can be found at www.nordicnanovector.com
