Earlier today the prestigious journal Cancer Discovery published the results of our program’s latest work in mantle cell lymphoma. Although previous clinical trials have demonstrated the effectiveness of ibrutinib in treating patients with mantle cell lymphoma, researchers also noted that some patient’s lymphoma developed ibrutinib resistance during treatment. Our findings revealed some insight into why this resistance occurs and offers several potential treatment strategies for patients who develop ibrutinib resistance. Based on their findings,
“…the researchers devised two treatment strategies that they tested in lymphoma cell lines. Both involve serial use of two anti-cancer drugs — the first to weaken or “prime” the cancer cells, and the second to deliver an added impact. Both use the experimental agent palbociclib (which selectively inhibits two cell-cycle promoting proteins, CDK4 and CDK6) to slow down the cancer’s growth and sensitize cells to the killing power of a second drug.”
As the study’s lead researcher, Dr. Selina Chen-Kiang commented,
“While for many patients ibrutinib represents a valuable treatment option, it has limitations, and we have been able to demonstrate how novel therapy combinations that target the cancer’s resistance pathways might possibly work better.”
These results build on years of laboratory and clinical work at WCMC, and they highlight the need for further research such as our ongoing trial with ibrutinib plus palbociclib
