Financial highlights

• Research and development expenses rose to $20.9 million for the six months ended June 30, 2026, up from $14.2 million year-over-year, driven by increased compensation, clinical activity, and raw materials.

• General and administrative expenses increased to $5.7 million from $3.9 million, mainly due to higher compensation and professional fees.

• Marketing expenses decreased to $0.6 million from $0.9 million, reflecting lower employee compensation.

• Financial expenses, net, surged to $41.4 million from $0.3 million income, primarily due to warrant liability remeasurement as share prices rose.

• Cash and equivalents increased to $104.8 million from $76.9 million at year-end 2025, supported by equity raises and milestone payments.

Outlook and guidance
