Safety • No serious adverse events or premature discontinuations • No clinically relevant ECG changes • No clinically relevant laboratory changes • Only adverse events considered possibly related to drug were associated with the subcutaneous administration of the product: mild redness and bruising at some injection sites 11 HERON THERAPEUTICS Advancing medicine. Improving Health.

Summary • Initial Phase 1 experience validates target product profile for HTX-011 • Desired pharmacokinetic profile for both bupivacaine and meloxicam achieved • Strong pharmacodynamic activity that correlated with pharmacokinetic profile observed – Rapid on-set of action without a large initial peak – 2-3 days of stable bupivacaine plasma levels correlated to 2-3 days of anesthetic effects • All three doses were well-tolerated • Phase 1 results support immediate advancement into Phase 2 12 HERON THERAPEUTICS Advancing medicine.
