CHICAGO – Consider using novel agents in chronic lymphocytic leukemia (CLL) patients who are refractory to treatment or who relapse within 2 years of first-line therapy, Dr. John G. Gribben said.
Ibrutinib or idelalisib/rituximab, or other novel agent combinations within clinical trials are his choice in these patients, thus fitness for therapy becomes irrelevant, he said at the American Society of Hematology Meeting on Hematologic Malignancies.
“Of course, I’m particularly excited by the results in CLL of ABT-199. We saw at [the International Workshop on CLL] last week that there are increasing numbers of patients who are on this therapy in combination with anti-CD20 monoclonal antibodies who are achieving minimal residual disease (MRD) eradication and are able to stop that therapy, unlike what we’ve been seeing,” he said. “I have a patient at my own center now who was treated with ABT-199 plus obinutuzumab within a clinical trial – a 17p deletion patient refractory to seven previous lines of therapy. Had a donor, I was trying to get him to transplant, and now he’s MRD-negative and off therapy, having had 6 months of therapy with ABT-199 and obinutuzumab. [This is] a very exciting combination.”
Other novel-novel agent combinations are also being looked at, he noted.
In CLL patients without 17p deletions who progress later than 2 years after initial chemotherapy, novel agents can be considered, as could alternative approaches with chemotherapy.
“But of course, in the setting of p53 deletions or mutations, then ibrutinib or idelalisib/rituximab, or novel agents like ABT-199 within clinical trials become the treatment approach to be thinking about,” he said.
