AZ and Daiichi’s Enhertu (trastuzumab deruxtecan) has been approved in US for the treatment of adult patients with unresectable or metastatic HER2-positive breast cancer who have received a prior anti-HER2-based regimen either in the metastatic setting, or in the neoadjuvant or adjuvant setting and have developed disease recurrence during or within six months of completing therapy.

Enhertu is a specifically engineered HER2-directed ADC.

CLINICAL AND REGULATORY

The combo did achieve its stated aim of demonstrating a lower rate of ocular toxicity with the combination, with 7% of patients having grade 3 ocular toxicity vs. 50% in the Blenrep monotherapy cohort.

DEALS AND FINANCING

Zymeworks rejected unsolicited non-binding proposal

Zymeworks announced that its Board of Directors, after thorough consultation with its financial and legal advisors, unanimously determined that the unsolicited, opportunistic, non-binding proposal from an activist shareholder, All Blue Falcons FZE, and its affiliates to purchase Zymeworks for $10.50 per share substantially undervalues Zymeworks and is not in the best interest of the Company and its shareholders. In addition, Zymeworks commented that the proposal lacks credibility by offering no information regarding potential sources of funding or any details on their ability to consummate such a transaction. Zymeworks also said it will continue to execute on developing its pipeline, including a HER2-targeted bispecific antibody and ADC against same target.
