Ibrutinib Demonstrates Continued Efficacy for CLL Patients at 3 Year Follow-up

Previous studies have demonstrated the efficacy ibrutinib (Imbruvica), an oral inhibitor of Bruton’s tyrosine kinase, has as treatment for patients with CLL. This has led to its approval by the FDA for previously treated patients with CLL and patients with CLL who have deletion 17p regardless of prior therapy. In a paper published online in Blood, a group of investigators, including Richard R. Furman, published long term follow up results from the original phase II studies of ibrutinib in patients with CLL. The paper presents results from a median three-year follow-up of 132 treatment-naive and relapsed/refractory symptomatic patients with CLL or SLL, receiving single agent ibrutinib. Longer treatment with ibrutinib was associated with improvement in response quality, durable remissions, and with diminishing toxicity and adverse side effects. For the treatment naïve group of patients, the 30 month progression free survival was 96%. For the relapsed refractory patients, the 30 month PFS was 69%, with disease progression being seen primarily in the patients with relapsed del(17)(p13.1) and/or del(11)(q22.3) disease. Findings from this study provide further evidence that ibrutinib is an effective and well tolerated long-term treatment for patients with CLL.

Classical Hodgkin Lymphoma Genome Sequenced by Research Team

In a recent study first published online, then as a plenary paper in the February 12 issue of Blood an inter-institutional team of researchers sequenced the genome of classical Hodgkin lymphoma (cHL). This sequencing allowed researchers to study the changes in proteins in individual patients, which could potentially lead to the development of new therapies targeting the cells affected by cHL. Their findings are especially notable as,

“Now we have a better idea of what mutations there are, and going forward therapies can be adapted to specific patient populations according to their genomic composition,” said senior author Dr. Ethel Cesarman, a professor of pathology and laboratory medicine at Weill Cornell Medical College.

Although scientists have sequenced the genomes of many other diseases, the cHL genome has remained elusive due to the difficulty of isolating Reed-Sternberg cells, which usually comprise less than 1 percent of a total cHL tumor. The team employed a technique that separates larger cells and looks at the proteins on their surface, called fluorescence-activated cell sorting, to successfully isolate the Reed-Sternberg cells and sequence the cancer genome, said senior author Dr. Mikhail Roshal, an assistant member in the Department of Pathology at Memorial Sloan Kettering Cancer Center.

These findings could potentially lead to more personalized treatment options for patients with cHL. They exemplify the bench to bedside approach taken by the Lymphoma Program and Meyer Cancer Center. Please look to this space for further updates about lymphoma news and clinical trials.
