• 40-60% of iNHL patients treated with a RTX-containing regimen are either refractory to therapy (10%) or develop resistance within five years, so having an alternative therapeutic target to CD20 is important • Relapsed/refractory patients may not tolerate chemotherapy because of age or co-morbidities, so “chemo- free” regimens are in high demand

Nordic Nanovector ASA Kjelsåsveien 168 B, 0884 Oslo, Norway www.nordicnanovector.com IR contact: [email protected] Betalutin®: A novel CD37-targeting radioimmunotherapy

• CD37 is highly expressed in B-NHL1

• 177Lu: a low energy β-emitter with a half-life of 6.7 days

• Mechanism of action: – Internalization and cell death – Crossfire effect targets cells with variable CD37 expression and poorly-vascularized tumour regions

14 1. Flinn IW. Blood 2011; 118: 4007–4008; Betalutin® is specifically designed as a one-time treatment for NHL: Compelling, unique and differentiated value proposition

Alternative target to CD20, well suited for NHL patients who progress after RTX-based regimens

Betalutin® High and durable response from one-time treatment in heavily pre-treated NHL patients*

Predictable and manageable toxicity*, important for elderly NHL patients who might not be able to tolerate chemotherapy

Convenience for NHL patients – simple, one-time treatment, QoL Convenience for physicians – ready-to-use, optimised resourcing

Potential synergy from combination with anti-CD20 mAbs and other therapies

21 Actions to drive patient recruitment

• Close working relationship with the PARADIGME CRO (ICON)

• Programme of Nordic Nanovector Management site visits – Demonstrates Nordic Nanovector’s commitment to PARADIGME and supporting centres when needed – Increased clinical site motivation and commitment

• Maintain site engagement with NANO Medical Scientific Liaisons (MSLs) / and ICON’s Clinical Research Associates (CRAs) – Designed to keep PARADIGME at front of mind in a competitive environment for these patients

• Team of 4 Medical Scientific Liaisons (MSLs) deployed in Europe and US – Medical affairs focused on strengthening relationships with key referrers – Leveraging Lymphoma Societies / Advocacy Groups / Patient organisations

• Communication of key updates of LYMRIT 37-01 data – presentations at key congresses (ASH, ICML, AACR) – Great tool for raising awareness and gaining KOL (Key Opinion Leaders) engagement

• Rolling programme of Investigator Meetings (multi country or country specific in some cases) – Create culture of shared goal and exchange of experiences – positive response to previous events

• Referral pathways mapped out based on experience from highest recruiting centres

22 Regulatory path focused on expedite product approval

• Orphan Drug Designation granted in US and EU in 2014

• Clinical plan for Betalutin ® agreed with FDA in September 2017 (type C meeting)

• Enhance dialogue with regulators to bring Betalutin® to FL patients quicker thanks to:

– Fast-track designation granted in the US in June 2018

– Promising Innovative Medicine (PIM) designation granted in the UK in October 2018
