Understanding Final Outcomes of DUBLIN-3 Study on NSCLC

Final Insights on the DUBLIN-3 Study Presented at ESMO Congress

FLORHAM PARK, N.J. — BeyondSpring Inc. (NASDAQ: BYSI), a notable biopharmaceutical firm, has revealed compelling final data from its DUBLIN-3 study focused on patients with 2L/3L EGFR wild-type non-small cell lung cancer (NSCLC). The findings were presented at the esteemed ESMO Congress, highlighting the trial's focus on combination therapy outcomes.

The DUBLIN-3 study under test aimed at assessing the efficacy of plinabulin when paired with docetaxel compared to docetaxel alone. This inquiry comes in light of the challenging prognosis faced by patients who have undergone previous treatments without achieving favorable outcomes. Existing therapies often lead to considerable side effects like severe neutropenia, a critical concern affecting patient quality of life.

The Challenge of Current Treatments for NSCLC

Current therapies often result in harsh side effects. Docetaxel, the standard treatment for patients with 2L/3L NSCLC, is known to cause severe neutropenia over 40% of the time. Six recent phase 3 studies focusing on patients who had undergone immune checkpoint inhibitors did not demonstrate a survival benefit versus docetaxel alone. Although some studies, such as LUNAR and TROPION-Lung01, have shown mixed results regarding overall survival, the standard care still poses risks that aren't negligible.

This scenario highlights the unmet need for improved therapeutic strategies in managing NSCLC, particularly for patients whose diseases have progressed despite prior platinum-based therapies. As these patients face dire outcomes, the DUBLIN-3 study results offer hope for better management options.

Implementation of the DUBLIN-3 Study

The DUBLIN-3 study enlisted 559 participants from 58 centers worldwide. Patients were either given the combination of plinabulin and docetaxel or received docetaxel alone. The trial's results underscored significant improvements in overall survival, progression-free survival, and objective response rates among those who received the combination therapy.

Particularly noteworthy was the substantial reduction in adverse events associated with the treatment. The research indicated that the combination therapy was well-tolerated, with minor differences in adverse events between groups, and a marked decline in the incidence of severe neutropenia among patients receiving both plinabulin and docetaxel.

Positive Outcomes from Combination Treatment

A range of positive outcomes has emerged from the DUBLIN-3 study. The combination approach not only curbed the instances of severe neutropenia but also improved the overall quality of life. The findings highlighted that patients undergoing the combined treatment experienced a relative gain in quality of life as measured by the Q-TWiST analysis, providing credible support for considering this treatment as a primary option in second or third-line NSCLC treatment protocols.

Furthermore, the lower rates of serious adverse events associated with the combination therapy compared to docetaxel alone indicate a favorable benefit-risk balance. Patients also reported fewer needs for granulocyte-colony stimulating factors, indicating overall better management of side effects.

Key Highlights from The Presentation

The ESMO Congress presentation emphasized several crucial factors:

• Well Tolerated: 99.6% of patients on the combination treatment reported at least one treatment-emergent adverse event.
• Reduction in Severe Neutropenia: A significant drop in the incidence of severe neutropenia was recorded in combination therapy.
• Quality of Life Improvements: Enhanced life quality was noted based on Q-TWiST evaluations.
• Manageable Side Effects: Most side effects remained manageable, allowing for better treatment continuity.
