I agree on the Dengue EU Orphan status as most likely next [kudos Puffer and Zinc cause I didn't initially think of that either.]
But I think the next catalyst may be a PR not only stating non-GLP Tox completion, but also announcement of completion of large master batch and initiation of the IND-enabling GLP safety and Tox studies for FDA.
Based on the Annual Report (see excerpt below), Tox Studies (non-GLP and GLP) do not need cGMP materials. For the GLP Tox study, NNVC needs to produce at least three to five batches of the injectable FluCide, analyze the product for comparability, and combine these batches to produce a master batch sufficient to perform the tox package studies with. The report says these manufacturing activities are currently in progress [Sept publication of AR] - and so they are either already done or are being completed for the GLP study in parallel with the execution of the non-GLP study.
To clarify (some are getting this mixed up). - GLP/cGLP speaks to CONDUCTING STUDIES according to current Good Laboratory Practices. - cGMP speaks to MANUFACTURING MATERIALS according to current Good Manufacturing Practices.
And according to PRs and ARs, NNVC has said they will do the following. 1. Manufacture materials for the non-GLP and GLP Tox Package studies in the existing small-scale facility (not cGMP or cGMP-like). 2. Manufacture cGMP/cGMP-like materials for human clinical studies in the new large-scale facility.
