Selected Notebook Entries — April–May 2025
15 February 2025
Added outlier flag to Batch 7B CDR entry today. The numbers don't work — ORR is too clean for a mixed-site cohort with that enrollment timeline. 9 adverse events I can account for. The other 9 — where did they go? Flagged for exclusion from primary analysis. Will discuss with K and R when they're back from investor meeting.
4 March 2025
Finally got 30 min with K [underline]Kavitha[/underline] to discuss Batch 7B. She said R [underline]Ravi[/underline] had reviewed it and "the numbers check out, the site reconciliation explains the discrepancy." When I asked to see the reconciliation document she said it's with the regulatory team. I asked Sanjay for it. He said he'd "look into it." Three weeks and nothing.

Checked CDR this morning. My outlier flag on Batch 7B is gone. I didn't remove it. The version I'm looking at now has Batch 7B as clean primary data. Kept a local CSV export from 16 February — comparing the two makes me nauseous. Someone has edited the repository. The data submitted to DCGI will be wrong. I need to do something about this before approval comes through.
1 May 2025
Sent the formal QA memo today [BNL/QA/2847/2025]. K and R are both named recipients. This is documented now. 48 hours. If there's no meeting by 3 May I am going to DCGI directly. I am not going to put my name on this filing.
4 May 2025
3 May came and went. No response to the QA memo. I emailed DCGI CDL last night — a preliminary warning. This morning I got a call from a DCGI coordinator — she said BioNexus Labs had already responded, said my concerns were unfounded. How did they know I'd contacted DCGI? The coordinator didn't seem interested in pursuing it. I need to go over her head.
5 May 2025
Spoke to P.R. [underline]Priyanka[/underline] today. Took a risk — showed her the CDR comparison. She went quiet for a long time. Then: "Anil sir, I already noticed this six weeks ago. I was afraid to say anything." She has access to the Block A CDR backup server — the archive from before the edit. We need both copies to prove the change was deliberate. She will pull the archive quietly.
6 May 2025
DCGI approval announced this morning. ₹4,200 crore NX-7 projection. [underline]My name is on that compound.[/underline] I feel physically ill. K gave a speech at the office. I couldn't stand to be in the room. P.R. texted — she has the archive. We're going together to file the formal complaint. Not email — in person, New Delhi, the CDL office. I'm drafting the letter tonight.
7 May 2025 (morning)
Party tonight. They expect me there. I won't be going — or if I do, it won't be to celebrate. The letter is nearly ready. The raw outcome forms from HYD site are locked in my car. When P.R. confirms she has the archive copy, I will send the letter and hand over the forms.
7 May 2025 (evening — final entry)
Called P.R. at 5:44. Told her to come into the lab tonight — not the party. She agreed. I'm going to Lab C to pull together the documents and wait for her.
HFSL Note: This appears to be the last entry in the notebook. The pen is still clipped to the last written page. Time of final entry not determinable from handwriting analysis alone.
