NWBO: Once In A Decade Best Stock Investment -- Regulatory Approvals Coming! [Dec10, 2022 在第一页加了中文简述]

Larry's new article (maybe helpful for newbies to understand some recent developments, particlarly MIA, MAA and what is DCVax-L and how it works, etc)
 
It happens in America, protected by its government. btw, this guy has donated massively to US politicians, and have recently gifted Harvard University $300 millions. As a result, Harvard has renamed its Graduated School of Arts and Sciences after this corrupted person.

Got some funds ready to add more shares next week if the price is still low. Life is beautiful even sometimes it goes circular, and doesn't break out with no return for years. If manipulations can make it go circular, the force of truth will definitely prevail in a much more powerful way later.

Today added two batches: 5.5k at $0.48, 5.8k at $0.485. No reason not to add more at these low prices.
 

Northwest Biotherapeutics (OTCQB: NWBO) one of the most exciting stocks trading on the bulletin boards today, is a heavily shorted biotech that recently reported positive top-line results from its phase 3 trial on DCVax®-L for Glioblastoma, the most aggressive type of brain cancer representing a a potential market expected to reach $1.4 billion by 2025. DCVax®-L has succeeded where well over 400 clinical trials for glioblastoma having failed and its highly effective. In the recent Phase 3 clinical trial both median survival and the “long tail” of extended survival were significantly increased in both newly diagnosed and recurrent glioblastoma brain cancer patients treated with DCVax®-L. Investors sentiment is high as countless medical professionals and Doctors have gotten behind DCVax®-L who believe the approval by the MHRA is imminent.

The shorts are trying to mislead investors on too that recently posting a fake MHRA complaint online. According to Fintech there are currently 39 million shares short of NWBO. In December the Company filed a lawsuit in Manhattan alleging Citadel Securities, Susquehanna and “other Wall Street firms drove down the price of NWBO through a series of illicit trading tactics.” It also includes Canaccord Genuity, G1 Execution Services, GTS Securities, Instinet, Lime Trading and Virtu Americas.

The next big step for Northwest bio is the submission of the marketing application to the MRHA in the UK. The MHRA has made DCVax a top priority to review and the review process could move forward very quickly if NWBO utilizes the rolling review submission process. Revenue just in the UK for GBM will be at least $200 million per year.

Northwest Bio has built a manufacturing facility in Sawston, UK spanning a total of 88,345 square feet on two floors and initial production capacity comprises two manufacturing suites, occupying approximately 4,400 square feet on the ground floor. These two suites, together with some additional support and storage space, have a potential production capacity of dendritic cell vaccines for about 40 to 45 patients per month, or approximately 450 to 500 patients annually.

Production of the first NW Bio dendritic cell cancer vaccine for a compassionate use patient at the licensed production facility in Sawston started a while ago. Since the issuance of the MHRA licence, Advent Bioservices has been conducting the required post-approval re-validations and testing, and the facility is now ready to scale up the manufacture of cell therapy products for clinical use.

On November 17 NWBO reported that in its Phase III clinical trial both median survival and the “long tail” of extended survival were increased in both newly diagnosed and recurrent glioblastoma brain cancer patients treated with DCVax®-L. The trial has met both the primary and the secondary endpoint under the Statistical Analysis Plan for the trial. The trial results were reported today in a featured publication co-authored by more than 70 physicians from leading institutions across the U.S., Canada, U.K. and Germany, in the peer reviewed cancer journal JAMA Oncology, entitled “Association of Autologous Tumor Lysate-Loaded Dendritic Cell Vaccination with Extension of Survival Among Patients with Newly Diagnosed and Recurrent Glioblastoma”.

The Company believes this is the first time in nearly 20 years that a Phase III trial of a systemic treatment has shown such survival extension in newly diagnosed glioblastoma, and the first time in nearly 30 years that a Phase III trial of any type of treatment has shown such survival extension in recurrent glioblastoma.

Glioblastoma is the most common and most lethal form of primary brain cancer. Standard of care (SOC) treatments have been virtually unchanged for nearly 20 years. With SOC treatments, patients typically survive for only about 15-17 months from diagnosis, with the tumor recurring at about 6-8 months from diagnosis and the patients typically surviving for about 7-9 months after recurrence. Five-year survival from diagnosis is only about 5%.

NWBO has an enormous following of investors, many of them medical professionals who are passionate in their support of DCVax®-L and its ability to completely disrupt the global market for Glioblastoma worth billions starting in the UK where MHRA approval is expected to come in 2023 and then on to the EME, a much larger market, which is believed the best way for eventual approval in the USA.

Disclosure: we hold no position in NWBO either long or short and we have not been compensated for this article.
 
A fellow investor has certainly taken some time to produce a lengthy synopsis about NWBO. I have not read it yet, thinking it may be of some use for anyone who may be interested:

 
In life there are times when it seems everything is paused. I believe we have been in one of those times now.

In Reply We thank Mandel and De Groot for their comments on our phase 3 nonrandomized controlled trial1 and their recognition of external control populations (ECPs) as an area of innovation. We agree that lack of access to individual patient data is a general problem in the field, and we already noted this as a limitation to our study.1 We hope this situation will start to change. Until then, the matching-adjusted indirect comparison methodology we used is a well-established approach for patient matching based on demographic and prognostic factors.2 The cutoffs we used (eg, age) mirrored the comparator trials.

Mandel and de Groot propose comparing our recurrent glioblastoma 30-month survival of 11.1%1 with 9% survival seen in just 14 patients from 7 phase 1 trials, where all 14 patients were treated with experimental virotherapies.3 Our ECPs were 640 patients comprising the control arms of 10 comparators trials.1 Comparing 14 treated patients from small studies would be less appropriate than our ECPs. Also, the same publication reported 24-month survival of 15% and 12% in virotherapy-treated and non–virotherapy-treated patients, respectively,3 while 24-month survival was 20.7% with autologous tumor lysate-loaded dendritic cell vaccine (DCVax-L), which compares favorably.

The commentators suggest that lack of progression-free survival reflects DCVax-L being ineffective. This speculation ignores the fact that current magnetic resonance imaging technology cannot differentiate true progression from pseudoprogression, particularly with immunotherapy.4

It is important to emphasize that the DCVax-L study end points, analyses, and specific external comparator trials were prespecified in the statistical analysis plan,1 which was codified prior to data lock and unblinding. Accordingly, all conclusions were based on prospective, not retrospective, analyses.

We likewise appreciate the comments from Rahman et al. We agree that external data can aid drug development in oncology, and that careful approaches are needed to ensure comparability. We therefore undertook multiple sensitivity analyses and other measures to avoid or address potential bias.

Regarding resection, our inclusion criteria required only an “intent for a gross or near gross total resection,”1 not actual achievement of it. Gross total resection was not achieved in 37% of patients in the DCVax-L study and ranged between 25.6% and 46% in the comparator trials. Moreover, extent of resection was one of the prespecified factors on which the matching-adjusted indirect comparison analysis matched the ECP and the DCVax-L patients.2 The benefit associated with DCVax-L remained statistically significant in this analysis.

Regarding early progression postchemoradiation, 3 of the 5 comparator trials likewise used this exclusion criterion. We ran sensitivity analyses in which the other 2 trials were excluded from the ECP, and the hazard ratio remained the same as in the original comparison.1

Although the inclusion criteria for entry into our trial were stringent, other trials applied even more stringent criteria,5 and yet their survival results in both the treated and control arms were similar to the ECPs, demonstrating that such stringency by itself was not associated with increased survival.

Rahman et al suggest 4 elements for using ECPs in future clinical trials. We agree that these are thoughtful recommendations to consider for future leveraging of ECPs for development of new treatments without needing placebo cohorts.
