While the new CML drug Asciminib demonstrates better efficacy, its most significant advantage is superior tolerability. Clinical trial data shows it causes significantly fewer treatment discontinuations due to adverse events compared to both Imatinib and second-generation TKIs, improving patient adherence and quality of life.

A patient survey reveals a significant evolution in treatment goals. Initially focused on survival and stopping therapy, patients with longer treatment experience and older patients prioritize daily tolerability and quality of life, even over the prospect of treatment-free remission.

To improve long-term tolerability of amivantamab, some experts advocate for a "marathon, not a sprint" approach. This involves aggressive dose holds or reductions at the earliest signs of toxicity, even low-grade, to prevent side effects from escalating and ensure patients can remain on effective therapy longer.

Contrary to the standard 150mg starting dose, many clinicians begin abemaciclib at 100mg BID. Data from the TRADE trial and retrospective MonarchE analyses show this improves tolerability, reduces early dropouts, and maintains efficacy, as patients who dose-reduced to 100mg performed just as well.

Despite label recommendations for rapid dose escalation of ropeginterferon, experienced clinicians advocate for a slower, more patient-centric approach. This prioritizes long-term tolerability and adherence, which is crucial for achieving disease modification, over achieving rapid hematologic control.

Clinicians emphasize that maintaining treatment continuity with a reduced, tolerable chemotherapy dose is superior to discontinuing therapy due to side effects. This approach helps patients stay on treatment longer, potentially improving overall survival.

The primary goal in Chronic Myeloid Leukemia (CML) has evolved from survival to tolerability and treatment-free remission. These goals are not uniform; younger patients prioritize stopping treatment to start families, while long-term patients increasingly value better tolerability over marginal efficacy gains.

For older, transplant-ineligible myeloma patients, quadruplet regimens are not administered at full strength. Clinicians proactively reduce doses of bortezomib, lenalidomide, and dexamethasone based on patient fitness and renal function to manage toxicity while maintaining efficacy.

Concerns over arterial events caused physicians to start CML patients on lower, less effective doses of ponatinib. Data shows a start-high (45mg) then reduce strategy is more effective for disease control and safely mitigates side effect risks, contrary to clinical practice.
