Tezspire: how was the first human dose set?

The public FDA and EMA reviews of Tezspire don't say how the first human dose was chosen. That rationale is in the IND, which is confidential, so it is missing for most approved products.

Use pharmacology data (target binding, receptor occupancy, in vitro human cells, PK/PD modelling) to estimate the lowest dose expected to have any biological effect (MABEL) and the active dose (PAD), and, for healthy volunteers, start at an exposure below the PAD unless robustly justified.

NOAEL / key findings: NOAEL was the highest dose tested in each study; minimal to mild serum cholesterol decrease at 300 mg/kg (EMA assessment report, p. 30)
