One toxicology summary, from flagged to approved
NWB-4417 is an oral RIPK1 inhibitor heading for its first-in-human IND, 44 days out. Here is how its 2.6.6 Toxicology Written Summary gets from three disagreeing numbers to an approved section and a drafted 2.4 overview, screen by screen, in the working solution.

The whole IND on one screen
Lena Ortiz · Nonclinical regulatory writerLena opens the IND: 44 days to submission on Nov 20, Module 2 sign-off due Oct 30. Two of eight sections are approved, 2,318 numbers have been checked and 4 are left to resolve. A map wires each of the 20 study reports to the Module 2 sections it feeds.
“1,284 findings extracted, each with its page and table.”

Every finding, with its page and table
Study report readerTX-311, the 28-day GLP rat study with 14-day recovery and TK, is 2,914 pages. The reader extracted 286 findings from it — target organ, NOAEL, ALT, hypertrophy incidence, AUC at the NOAEL — each with its page, a confidence score and the report passage highlighted.
It never infers a NOAEL the study director did not state.

A number that disagrees with its source
Lena Ortiz · Nonclinical regulatory writerThe draft opens with every sentence cited. One is red: ALT at 100 mg/kg/day is written as 1.8-fold in females. Beside it, Table 11 of TX-311 on page 52 is open, with a line from the sentence to the cell — 1.5-fold for females; 1.8 is the male value.
“Disagrees with the source. The draft repeats the male value.”

Digits transposed in the dog AUC
Lena Ortiz · Nonclinical regulatory writerLena takes 1.5 from the source and moves on. Next flag: the AUC0–24 at the dog NOAEL reads 22,400 ng·h/mL. Table 9 of TX-312 gives 24,200 (sexes combined). She chooses “Use the source value”; “Keep mine” is there, but sign-off stays blocked until the number matches.

The margin, recomputed
Number checkerThe dog margin was built on the mistyped AUC: 22,400 ÷ 610 = 36.7, written as 37-fold. The number checker recomputes it from the source values — 24,200 ÷ 610 = 39.7, so 40-fold — and shows its working against PK-230: 79-fold to the rat NOAEL, HED 4.8 mg/kg, maximum recommended starting dose 29 mg.
“Number checker recomputed the dog margin: 37 → 40-fold.”
- 06Checked
428 of 428 numbers match
Number checkerThe number check for 2.6.6: 428 numbers in 186 statements — 367 exactly as reported, 61 derived and recomputed (margins, HED, fold changes), 0 disagree. Each row shows the value in the draft, the value in the source and where it sits in the report.
“Every number matches its source.”

The author signs, with the meaning recorded
Lena Ortiz · Nonclinical regulatory writerLena signs with her user ID and password. The meaning of the signature is “I drafted this section with the agents and checked every number against its source.” The AI use is recorded with it: drafted by the summary writer, 428 numbers checked by the number checker, 3 corrected from the sources.
- 08Approved · Oct 7
The toxicologist approves the science
Dr. Omar Haddad · Study toxicologistThe section goes to Dr. Omar Haddad, its approver. He sees Lena’s author signature and that every number matches, then approves with his own e-signature: “I approve the scientific content and interpretation of this section.” Every fix and both signatures are in the section history.

The 2.4 overview, drafted from the approved sections
Nonclinical summary writerWith 2.6.6 approved, the summary writer drafts the 2.4 Nonclinical Overview from the 2.6 sections and the PK-230 starting-dose rationale: 142 statements, every one cited. The number checker recomputes the margins and HED; the consistency checker compares the overview with each section and the Investigator’s Brochure v3.0.
Ready for Lena’s review — then Dr. Maya Chen approves.

How the summaries are holding up
Dr. Maya Chen · Head of nonclinical safetyHours to a first draft by section against the typical hours by hand, statements linked to a source, numbers matched first time, review rounds per section — and what reviewers changed, by quality area. Reviewers spend their edits on emphasis and clarity; almost none on correctness.
