BETHESDA, Md., Oct. 13, 2023 /PRNewswire/ -- Northwest Biotherapeutics (OTCQB: NWBO) ("NW Bio"), a biotechnology company developing DCVax personalized immune therapies for solid tumor cancers, provided an update today about its progress toward submission of a Marketing Authorization Application (MAA) to the Medicines and Healthcare Products Regulatory Agency (MHRA)(the equivalent of the U.S. FDA) in the U.K. for commercial approval of the Company's DCVax-L treatment for glioblastoma.    

The Company reported that the majority of the MAA has been completed, and all but one of the key sections of the MAA have been delivered to the publisher. The publisher is an independent party who does the final step of the preparation for the submission: formatting, checking references and the like.

The Company and its consultants are working intensively to finalize this last key section of the MAA, after overcoming an unexpected delay in that regard. The Company strongly believes that after so many years of work on the DCVax-L program, taking some additional time to help ensure that the full MAA package is as strong as it can be is especially important since the Company plans to submit applications to multiple regulators.    

An additional factor in the timeline is that certain expert consultants who are key to this remaining section will be temporarily unavailable during the next two-week period, returning the week of October 30.  The Company anticipates that the remaining section of the MAA package will be delivered to the publisher within about two weeks after the consultants return.

The Company further anticipates that once this last section of the MAA is delivered to the publisher, they will need about two to three weeks to complete their work on both the last portion and the integrated whole.  With this timeline, the submission of the MAA to the MHRA would take place between mid and late November.  The Company plans to provide updates when the delivery is made to the publisher and when the MAA is submitted.
