Previously, we discussed the role of new agents being developed for aggressive non-Hodgkins lymphoma (NHL) with Dr Nancy Valente of Genentech, particularly how their antibody drug conjugates (ADCs) could have a potential role to play in revolutionizing treatment for patients with an otherwise poor prognosis.

The second half of the interview from ASCO 2014 focuses on more indolent disease, namely chronic lymphocytic leukemia (CLL) and the role of their novel therapeutics obinutuzumab (Gazyva) and ABT–199/GDC–0199.

We’ve heard a lot of positive data about the anti-CD20 monoclonal antibody, obinutuzumab, but the Bcl2 inhibitor undergoing co-development with AbbVie has had a bit of a chequered history to date. There is no doubt that ABT–199/GDC-0199 is highly potent, while lacking the severe myelosuppressive effects (thrombocytopenia) of its predecessor, navitoclax — which can be both a blessing and a curse — as the phase I single agent investigators discovered recently when severe tumour lysis lead to two sudden patient deaths.

It is important to address these issues expeditiously in a safe and rational way to ensure patient safety for those who enroll in both current and future trials. This is a critical issue we discussed at length with Dr Valente and how the company has been handling it.

At the AACR Molecular Targets meeting last November, many readers will remember that we learned about Genentech’s research plans for combinations with GDC–0199 in CLL and NHL in an interview with one of the scientists for that program, Dr Deepak Sampath.

Today, it’s time to look at where and how this exciting agent might impact CLL. Obviously, both CLL and NHL have commonalties and overlap, since they are both B cell disorders, so often what works in one disease often works well in the other too, as rituximab has clearly demonstrated.
