Acute Myeloid Leukemia (AML) is usually a disease of the elderly and an area of high unmet medical need, especially in those who unfortunately relapse post stem cell transplantation (SCT) or are considered ineligible for a transplant. In some ways, it has languished in the graveyard of R&D with very few new therapies approved by the FDA or EMA over the last decade. In fact, it has been quite the opposite with Pfizer’s gemtuzumab ozogamicin (Mylotarg), an anti-CD33 antibody drug conjugate (ADC) approved and subsequently withdrawn from the US marketplace following lack of confirmatory phase III data.
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.
Over the last two years there has been a lot of focus on indolent lymphomas (iNHL) and chronic lymphocytic leukemia (CLL) with numerous new targeted therapies being tested in clinical trials including ibrutinib (Imbruvica), idelalisib, ABT–199 and IPI–145 to name a few.
A regular reader of BSB wrote in asking for an update on Amgen’s blinatumomab, an anti CD3/CD19 bispecific antibody being investigated in B cell adult acute lymphoblastic leukemia (B-ALL) and Non Hodgkins Lymphoma (NHL). It has orphan designation for both indications.
One of the overlooked highlights from ASCO this year was new data in diffuse large B cell lymphoma (DLBCL), which is an aggressive form of Non-Hodgkins Lymphoma (NHL). DLBCL is the most common form of NHL accounting for nearly one third of newly diagnosed NHL cases each year in the USA. Most of these people are adults rather than children.
Our ASCO 2014 conference coverage continues with more gems from the poster sessions; it’s where we believe you find the promising gems that offer hints of future promise (or not) as the case maybe.
Readers of the blog and those who’ve seen us at conferences will know that we spend a lot of time in the poster halls at meetings such as AACR, ASCO, ASH, ESMO/ECCO.
Over the last few days, we’ve covered data from the leading checkpoint inhibitors from BMS, Merck and Roche, but what about other agents in development in immuno-oncology? One of the companies that burst on the scene in Chicago at ASCO 2014 with solid data was AstraZeneca with their anti-PD-L1, MEDI4736.
One of the most exciting presentations that I heard at ASCO 2014 – the sort that give you goosebumps and elicit a wow from people sitting next to you – was not in the plenary or even a tumour type oral session, but a clinical science symposium.
PARP inhibitors have had a chequered history as anti-cancer agents from the lows of the failed iniparib (Sanofi) phase 3 trial in triple negative breast cancer (TNBC) and olaparib (AstraZeneca) in ovarian cancer to the highs of the initial waterfall plots for BMN673 (Biomarin) in BRCA-positive breast and ovarian cancers and a successful graduation from the ISPY2 trial in the triple negative signature for veliparib (AbbVie). In between those two extremes, there has been a lot of uncertainty.
