No, the CHM meeting isn't full UK approval, it may, or may not be required, but it isn't the approval we're waiting for. I've not backed off at all, if I'm right about the 150 days starting on submission we could hear tomorrow, or very shortly thereafter. If it's 150 from preliminary validation we're a little over a month away. Nothing says the UK must take the entire 150 day period, so regardless, approval could come any day.
If it's true that no CHM meeting was required, to me that would indicate they've made up their minds and it's only a matter of doing all that's expected of them before announcing the result.
If they were notified of approval before the open tomorrow, the question might be, do they announce it immediately, or better plan how they're doing it a day, or two later. Sadly it doesn't seem to matter when they decide to announce, it will be well before the opening bell and I'll be asleep if they should schedule a webcast before the bell, typically at 5:30 my time, 8:30 in New York. Many investors on the East Coast may not be looking for such a notification. I'd love to see a company announce on Saturday or Sunday that they'll be holding a webcast before the open on Monday, that would be enough to have me set an alarm and listen to what's happening.
Regardless if it's tomorrow, or in roughly the next month, we are in for some very interesting, and hopefully very profitable, times.

A 1.5 ounce serving of bourbon contains zero grams of sugar. Straight bourbon doesn't contain added sugar during the production process. The primary ingredients of bourbon are water, corn, rye or wheat, and malted barley, which undergo fermentation, distillation, and aging. During fermentation, yeast breaks down the sugars from the mash, creating carbon dioxide and alcohol.

nothing"? well that's not true, you know it.
you know all the achievements with the trail, manufacturing, patents and so on!
it all took longer than predicted but it happend!
so does approval and you are right on that point - it should have happend between 2016 and now as many (myself) believed it would and talking about in our comments- and we were wrong. blain and simple WRONG
but there always comes a time when we leave things behind, achieved goals, and an event , a release which seemingly never wiill come true CAME TRUE
(the same as i always say to friends and whoever. there comes a time after putin, after things worse, seemingly endless - seemingly no solution, enduring for so long. so we are used to it day by day, week by week. . . . . . to a point where these things are (seemingly) quite "normal" . . . . belong to the day, to the present.
but there comes a time . . . . . )

Doc, I personally don’t think the MHRA will inspect Charles River Labs' (formerly Cognate’s) or Fraunhofer’s manufacturing facilities, since they are not currently being used (or immediately planned) for initial DCVax commercial production.
I think, but I’m not sure if the MHRA is like the FDA, in that they will generally schedule a pre-license or pre-approval inspection of the intended commercial manufacturing facility after the midpoint in the review process, and request to view all phases of the production operations for the selected product under review in the marketing application.
Shutting down operations of a GMP facility for construction, maintenance, cleaning, and disinfection is complex, but routine, and would not effect anything unless a significant change to the plant and equipment occurs, which would usually require requalification. (except that a pre-approval inspection obviously could not be scheduled during the shutdown)

ski, are you asking if I think the UK inspectors need to look at the manufacturing sites used for the clinical trial, since only Sawston is indicated for commercial manufacturing at this time?
If so, my answer is no, it shouldn’t be necessary as long as there were no potential red flags raised during the review of the clinical trial patient records or manufacturing records from those sites that were sampled. However, that may not be the case, and not all inspectors/regulators are equally thorough, or think the same. Generally, the first marketing application and regulatory review for a new drug, or molecular entity, is more thorough and takes longer than subsequent marketing applications for additional use of an already approved drug. (since the appropriate nonclinical and manufacturing data may have already been reviewed by the Agency in the initial application)
Visits to potentially obsolete manufacturing sites is certainly one area of the 150-day accelerated review process that could, and probably will be cut to expedite the review from the standard timeline. As additional commercial manufacturing sites are added, they may be inspected at that time.

Right ATLnsider, as you indicate, in the UCLA combination studies with DCVax-L, the poly-ICLC is administered separately as an adjuvant. However, in the early studies with DCVax-Direct, it was used in the manufacturing process, which increased the potency. (poly I:C, or its derivative, poly-ICLC is included in the Direct patents, and the more recent hyperactive patents)
NW Bio Receives U.S. Patent On Broad Processes For Producing More Potent Dendritic Cells
Next Generation Technology Already In DCVax®-Direct; Will Be Applicable To All DCVax® Products
Building upon the pure immature dendritic cells, NW Bio's patented methods develop mature and activated dendritic cells that are far more potent than dendritic cells produced in the standard way. For example, NW Bio's dendritic cells produce as much as 10X or more the amount of signaling compounds which are key to mobilizing other active agents of the immune system, such as T cells (which infiltrate and attack tumors) and B cells (which produce antibodies).
NW Bio is already using these next generation methods for producing more potent dendritic cells in its production of DCVax-Direct. The same patented methods for activating dendritic cells were also used in the pre-clinical animal studies with DCVax-Direct. In those studies, injection of these potent dendritic cells into some of the tumors in each of the animals resulted in complete clearance of all tumors (both the tumors injected with DCVax-Direct and the tumors not injected) in 80-100% of the animals in the various studies, indicating a system-wide immune response.
?
Going forward, NW Bio's now patented methods of producing more potent dendritic cells will also enable development of the next generation of NW Bio's other two product lines: DCVax-L and DCVax-Prostate. The current DCVax-L and DCVax-Prostate products have already delivered striking results in clinical trials to date, extending the time to tumor recurrence and the patients' survival time by 1-1/2 to 2 years or more, with a substantial portion of patients going far beyond that. Incorporating NW Bio's patented methods for more potent dendritic cells will enable production of enhanced versions of these DCVax-L and DCVax-Prostate products.

For DCVax-L, Northwest Bio uses the most common method of culturing PBMC’s to generate dendritic cells, which relies on the monocytes adhering to the bottom surface of the polystyrene culture vessel in a medium of granulocyte macrophage colony-stimulating factor (GM-CSF) and interleukin 4 (IL-4), which induces differentiation into dendritic cells, and activates them.
I believe this increased-potency knowledge was gained in the DCVax-Direct studies because they were attempting to overcome the tumor’s defenses by delaying the activation and maturation of the dendritic cells, which wasn’t possible using culture flasks that are used to produce DCVax-L, so they attempted culturing the monocytes in suspension, in a bagged system without IL-4, using only GM-CSF, and then various other mediums to optimize and activate the dendritic cells, including poly I:C.
Northwest Bio stated that they intended to use this higher potency method across all product lines for the next generation of DCVax, but the Flaskworks’ eden system uses a polystyrene culture cartridge (similar to the well plates used in manual culturing protocols) which the monocytes adhere to, so I’ve not seen evidence that they’ve actually changed the manufacturing method for the next generation of DCVax-L. I believe the method of combining poly-ICLC with DCVax-L requires separate (nearly simultaneous) injections to produce the more potent effect in vivo.
