Just joined. I am looking for some guidance from a pharma sponsor or from a government/non-profit working with Phase II-III patient clinical trials.
My org wants to create DOIs for 200 de-identified cancer clinical trials shared on our platform. Was hoping to tie in the 11-character ID string used by clinicaltrials.gov, for example “NCT12345678”. Our accrual is slow, expecting to have no more than 1000 items by 2030.
Within the current 200 data items, there are some duplicates, some are subsets of others, and a small number were never assigned a clinicaltrials.gov identifier.
Of course we could simply number them sequentially, but our first thought was that with the right convention we could create a “speaking number/letter” combination that shows relationship to other items and that shows heritage to their source trial (clinicaltrials.gov identifier) or some attribute (type of cancer).
Hoping for any suggestion to lead me to create a clear and maintainable convention. Thanks!
