Claude drafted a regulatory document in four hours, not three months

Claude wrote a first draft of a drug regulatory document in four hours. Done by hand, the same job took about three months.

That comes from Anthropic’s write-up of early drug development work with six partner organisations, published on 27 October 2026.

At Enveda, chemists were spending up to 75% of their time on paperwork. That is the bottleneck Claude was pointed at, not the chemistry.

Across 1,061 pages of documentation, Claude caught all 11 issues the human reviewers found and flagged seven they had missed.

Human review time fell from over 25 hours to under three.

For the second regulatory document Claude drafted, standard human review found one minor error.

At Divergence Labs, Claude generated roughly 35,000 antibody designs in about a month, largely autonomously. Three of the 20 designs that could dislodge IgE did so more effectively than the standard medication.

Anthropic is clear that the work is still at an early stage and mostly preclinical.
