Do to TO censorship of free speech, I've left out the handle of this "X" post.
It appears the Defendant Market Makers,
@MerrilllLynch and @cibc, do not want the number of alleged spoofing episodes to be made public. They're already public. See above.
"We write on behalfof Defendants under this Court's direction in the November 25 the Court maintain under seal references in the Order & Opinion to the specific
numbers of alleged spoofing episodes that Jonathan Brogaard, Harington's proffered liability expert, attributed to Defendants' customers in his reports!"

Here's an interesting BLA submission to keep track of as a gauge of FDA flexibility. AstraZeneca and Daiichi Sankyo have shared the data they believe can secure approval for datopotamab deruxtecan (Dato-DXd) at the second attempt. The partners showed off subgroup overall survival data that exceeded the result seen in the broader population, providing evidence to support the pivot.
Originally, the partners applied for FDA approval of the antibody-drug conjugate (ADC) in patients with advanced or metastatic nonsquamous non-small cell lung cancer (NSCLC). Last month, AstraZeneca and Daiichi withdrew that filing and resubmitted for approval in a subset of patients with EGFR-mutated NSCLC. They are pooling a subset of the P3 data (i.e. EGFR mutated) w data from a P2 trial.AstraZeneca and Daiichi included 117 patients in the analysis: 78 from a phase 2 study in patients with actionable genomic alterations and 39 from a broader phase 3 trial. Median OS in the overall population of the phase 3 trial was 12.9 months, a result that was statistically no better than the 11.8 months seen in the control arm.
Median progression-free survival (PFS) was numerically higher in the pooled analysis, 5.8 months, than the phase 3 trial, 4.4 months. And a bump in the response rate, from 26.4% to 42.7%, wrapped up a set of data that suggests Dato-DXd is more effective as a later-line treatment in people with EGFR-mutated NSCLC than in the wider patient population....
...Susan Galbraith, Ph.D., executive vice president of oncology R&D at AstraZeneca, discussed what the FDA made of the data on an earnings call after disclosing the withdrawal and resubmission last month. The FDA has “noted the favorable benefit risk profile in EGFR-mutated lung cancer,” Galbraith said, and “is interested in the particular subgroups where the greatest benefit is seen.” That interest led the FDA to EGFR. https://www.fiercebiotech.com/biotech/astrazeneca-daiichi-share-data-behind-dato-dxd-do-over-amid-second-bid-lung-cancer-approval?utm_medium=email&utm_source=nl&utm_campaign=LS-NL-FierceBiotech&oly_enc_id=4891B5384067C3X

I asked Copilot - Could the submittal for DCVax-L to the FDA include an agnostic designation?
Yes, the FDA does allow for tissue agnostic designations for certain drugs. A tissue agnostic drug targets a specific molecular alteration (biomarker) across multiple cancer types, rather than being specific to one type of cancer
1
. This means that the drug can be used to treat different types of cancer that share the same molecular target.
For example, pembrolizumab was the first drug to receive a tissue agnostic approval for patients with unresectable or metastatic, microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) solid tumors.
To pursue a tissue agnostic designation, the submission to the FDA should include comprehensive data demonstrating the drug's efficacy and safety across multiple cancer types with the targeted molecular alteration. This involves a thorough understanding of the molecular pathways involved and robust clinical trial data.

I have every expectation that Direct development will restart in 2025
I would be very surprised to see first patient dosed in 2025.
Mainly is the manufacturing. They have tasked Advent with either finding a way to refurbish the 12+ year old TTF equipment used in the previous P1, or else find a commercially available alternative. The former might prove difficult and/or timely. The later will certainly take some time. Whatever they do, they need to get it evaluated and in, and then GMP approved at Advent prior to the trial.
We also know nothing about the process to switch to "DCVax-Direct Gen 2", that also could impact times.
And if for some reason they actually decide to evaluate alternative maturation agents, that could go a couple years.
Even when NWBO had all the MFG in place and plans set to run trials they failed to launch several times in the past.

I asked co-pilot about the long tail with DCVax-L
The "long-tail" in clinical trials refers to the extended survival observed in a subset of patients who live significantly longer than the median survival time. In the context of DCVax-L clinical trials for glioblastoma, the long-tail represents patients who have exceptionally prolonged survival times compared to the average
2
.
Key Points on Long-Tail Survival with DCVax-L:
Extended Survival: In the Phase 3 trial, a subset of patients exhibited survival times well beyond the median overall survival (mOS) of 23.1 months.
Significant Extension: Some patients lived for more than 30 months, with a Kaplan-Meier derived mOS of 46.5 months.
Not Explained by Prognostic Factors: The extended survival in this subset of patients was not explained by known prognostic factors, indicating a potential unique benefit from DCVax-L.
Safety Profile: The treatment showed a benign safety profile, with adverse events comparable to standard therapy alone.
This long-tail survival is particularly encouraging as it suggests that DCVax-L may offer meaningful survival benefits to a subset of patients who might not respond as well to conventional treatments.
Would you like more detailed information on any specific aspect of the long-tail survival or the clinical trial results?
What percentage had a long tail?
In the Phase 3 clinical trial for DCVax-L, 30% of patients lived for at least 30 months, and 24.2% of patients lived for at least 36 months. This indicates a significant long-tail survival benefit for a subset of patients treated with DCVax-L.
Would you like more information on the trial results or details about the patients who experienced long-tail survival?

Even cancer patients have not been able to get TICE BCG on occasion, and you just brush off small companies and research facilities having to go without and find funds for another version (not approved or manufactured here) to go elsewhere and start over with something else, and why would a company pursue an ingredient in yet another trial when the manufacturer hasn’t completed a new facility since 2012 and doesn’t intend to until 2026, and then only slowly.
For example:
August 2019
Nonrandom’ availability
Despite Merck’s practice of allocating [Tice BCG] based on historical purchasing, patterns of shortages have not emerged. In some cases, large academic centers are experiencing shortages, whereas others have plenty of BCG in stock. — https://www.healio.com/news/hematology-oncology/20190805/bcg-a-realworld-example-of-health-care-rationing

No, but I would think that parsing thru the MAA PR gives clues to the additional data such as proteomics we didn’t expect would be in the MAA. Just the meta data backing up the lab analysis, Pathology reports, Expanded Access Protocol and the pseudo group that was separated out would add… a 100,000 pp or two.
As you may surmise, I don’t have a clue. What will give you a very strong clue is the newly issued FDA guidance that just came out.
