Which one is more effective, acotinib/cancostat or ibrutinib, and what is the evaluation?

In the field of targeted therapy for B cell-related hematological tumors (chronic lymphocytic leukemia, etc.) , BTK inhibitors have become important treatment pillars, among which ibrutinib and Acalabrutinib (Acalabrutinib) are the two drugs that have received the highest clinical attention. When many patients face treatment options, they will be concerned about which of the two drugs is more effective and which is more suitable for long-term use. Judging from the guidelines and clinical application evaluation, the two are highly consistent in their core treatment goals. They both inhibit the Bruton's tyrosine kinase pathway and block the survival signals of abnormal B cells to control disease progression. Therefore, in terms of overall efficacy, there is no simple conclusion of "complete replacement" or "absolute superiority or inferiority".

As the first generationBTK inhibitor, ibrutinib has been on the market earlier and has rich experience in clinical application. It has accumulated a large number of use cases in a variety of B-cell malignant tumors. It has a stable effect and covers a wide range of people. It is the first targeted therapy drug that many patients are exposed to. Because of this, the efficacy evaluation of ibrutinib in the real world is relatively mature, and doctors are more familiar with its usage rhythm and adverse reaction management. However, as the medication time is prolonged, some patients may have tolerance challenges, which has also prompted the medical community to continue to explore more selective BTK inhibition options.

Acotinib is a new generation of BTK inhibitor developed under this background. From the perspective of its mechanism of action, it minimizes interference with other kinase pathways while maintaining its inhibitory effect on BTK targets. Therefore, it is often considered a "more precise" BTK inhibitor in evaluations. This improvement in target selectivity makes it easier for some patients to maintain stable medication during long-term treatment and reduces interruption of treatment due to uncomfortable reactions. From the perspective of efficacy itself, acotinib is stable in controlling the disease and is especially suitable for patients who require long-term management and pursue a balanced quality of life.

On the question of "which one is more effective", experts prefer to evaluate from the "overall treatment experience" rather than a single efficacy indicator. For patients who receive BTK inhibitor treatment for the first time, the difference in disease control ability between the two drugs is not obvious. What really affects the choice is often the patient's individual differences, comorbidities, and tolerance to adverse reactions. Some patients who have experienced discomfort after using ibrutinib may have improved treatment continuity after switching to acotinib. This is one of the important reasons why acotinib is gradually receiving attention in clinical practice.

From a long-term treatment strategy, acotinib and ibrutinib are not simple“Upgraded relationships” are therapeutic tools with different characteristics. Ibrutinib is suitable for people with mature experience and clear indications, while acotinib emphasizes precise inhibition and long-term tolerance. Guidelines and clinical practice generally agree that both drugs can achieve stable disease control as long as they are used regularly in the appropriate population. The final choice of medication should be comprehensively evaluated by the doctor based on the patient's disease type, previous treatment history, and individual risks, rather than simply "which one is stronger" as the basis for judgment.

Generally speaking, acotinib and ibrutinib have their own advantages in terms of effectiveness, and the focus of evaluation has gradually shifted from "who is more effective" to "who is more suitable." For patients, understanding the positioning differences of the two drugs and making individualized choices under the guidance of doctors is the key to achieving long-term benefits.
