NovalGen announces compelling data from the Phase 1/2 Study of NVG-111 at the ASCO Annual Meeting

- First clinical data for NVG-111, a novel ROR1xCD3 bispecific antibody in patients with relapsed / refractory CLL and MCL

- Early data demonstrates promising efficacy with a predictable and manageable

safety profile

London, United Kingdom, May 26, 2022– NovalGen Ltd (“NovalGen”), a biopharmaceutical company developing breakthrough cancer therapies, announces first clinical data from the ongoing Phase 1/2 study of NVG-111, a novel ROR1 targeting bispecific antibody T cell engager, in patients with relapsed and refractory Chronic Lymphocytic Leukemia (CLL) and Mantle Cell Lymphoma (MCL), in a poster presentation at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting McCormick Place, Chicago, IL, June 3 to 7, 2022. The Company will also be presenting additional clinical data at the conference.

As of the January 31, 2022 data cut-off date, 6 patients had been enrolled to the study; three into each of the accelerated dose titration (ADT) cohorts and the remaining into a 30 µg/day flat dosing cohort. Early signs of efficacy and evidence of response was observed in all patients from Cohort 2 onwards. Amongst these, 2 patients had undetectable MRD in the blood with one being MRD negative in the bone marrow and the remaining patients achieved partial responses. NVG-111 was well tolerated with the most common adverse event being transient, Grade 1 lethargy, headaches, nausea, vomiting and thrombocytopenia. Dose escalation is ongoing, including exploration of step-up dosing.

“The safety and selectivity of NVG-111 observed in the pre-clinical studies have translated into the preliminary data in this on-going Phase I/II study,” said Professor Amit Nathwani, Founder and CEO of NovalGen. “We are encouraged by these early clinical data, demonstrating a predictable and manageable safety profile, alongside promising efficacy and it underscores NovalGen’s commitment to bring transformational therapies to patients”.

Dr Parag Jasani, Consultant Haematologist with NHS practice at Royal Free London NHS Trust and University College London Hospitals and Chief Investigator on the study added, “NVG-111 represents an important, novel treatment opportunity for patients with CLL and MCL as well as many other hematological malignancies. The data in this heavily treated patient population are encouraging and warrants further investigation, with the potential to broaden its use into other malignancies.”
