The big news yesterday evening was that Amgen’s phase III FOCUS trial in relapsed/refractory multiple myeloma failed to meet its primary endpoint of overall survival (HR=0.975).
This week Amgen announced that their second generation proteasome inhibitor, carfilzomib (Kyprolis), had met the primary endpoint of progression free survival (PFS) in the phase III ASPIRE trial. This study compared the triple combination of Kyprolis plus Revlimid and low dose dexamethasone (KRd) to the doublet of Revlimid plus low dose dexamethasone (Rd) in relapsed/refractory multiple myeloma. The overall survival (OS) is not yet mature and statistical significance was not been reached at the interim analysis. We will have to see how that data is looking in a few months time at the American Society of Hematology (ASH) meeting in December.
One of the things I most enjoy in cancer research is hearing wonderful patient stories from oncologists who are at the coal face of clinical trials. They get to deal with death and dying every day and like those in Pharma R&D, also live for the successes, the drugs that make it through pipeline despite great odds against them and make a meaningful impact on the daily lives of ordinary people.
Today’s post focuses on another question from a reader, who asked: “How will we decide which therapies to give patients with metastatic melanoma once the new immunotherapies are available?”
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with Pfizer’s gemtuzumab ozogamicin (Mylotarg), an anti-CD33 antibody drug conjugate (ADC) approved and subsequently withdrawn from the US marketplace following lack of confirmatory phase III data.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.
