Brief Summary:

This is the first clinical trial of the drug NVG-111, and will include patients with certain types of blood cancer called chronic lymphocytic leukaemia (CLL), small lymphocytic lymphoma (SLL) and mantle cell lymphoma (MCL). NVG-111 is a bispecific antibody drug, having two "arms", one arm attaches to a substance on cancer cells called ROR1, the other arm attaches to the body's immune cells directing them to kill the cancer cells.

The trial has two parts, the first part tests the safety of the drug at different dose levels. Once the first part of the study is complete a dose will be chosen for the second part of the study. The second part of the study will test how well NVG-111 works in treating these diseases.


Condition or disease Intervention/treatment Phase
Chronic Lymphocytic Leukaemia Small Lymphocytic Lymphoma Mantle Cell Lymphoma Drug: NVG-111 Drug: NVG-111 (RP2D) Phase 1 Phase 2

Detailed Description:

Receptor tyrosine kinase-like Orphan Receptor 1 (ROR1) is a protein which is expressed at high levels on many types of haematological cancers but is absent or expressed at low levels in normal adult organs. NVG-111 is a bispecific antibody T cell engager, comprising tandem single chain variable fragments (scFv), one arm binding to ROR1 on cancer cells, the other to cell surface CD3 on lymphocytes. Dual binding of NVG-111 causes MHC-independent immunological synapse formation, releasing perforins, granzyme B and cytokines, resulting in targeted killing of the cancer cells.

This is a Phase 1/2 first in human study to assess the safety, pharmacokinetics and efficacy of NVG-111 in patients with debulked, relapsed or refractory CLL/SLL and MCL on at least 2nd line therapy. NVG-111 will be added on to existent therapy which will continue through the study.

In Phase 1, a range of doses will be studied in sequential cohorts to understand safety, pharmacokinetics and pharmacodynamics of the drug and establish the recommended phase 2 dose (RP2D). At each dose level, patients will receive 3 cycles of NVG-111 by continuous intravenous infusion, each cycle consists of 21 days treatment followed by 7 days break. An additional 3 cycles may be given depending on the response seen.

In Phase 2, efficacy and safety of NVG-111 at the RP2D will be studied in separate cohorts of CLL/SLL and MCL patients.

All patients will have a safety follow up visit 4 weeks after completion of treatment with NVG-111, and will then enter long term follow up for up to two years to evaluate the duration of efficacy.
