Ive searched high and low for this scenario but keep running into more simple solutions
for example
RewriteRule ^stays-the-same/[^A-Z]*[A-Z] %1 [R=301,L,NE]
The goal is to see if the url fits either of these possibilities
/stays-the-same/variable/*
/stays-the-same/variable_*
/item-1/stays-the-same/variable_*
/item-1/stays-the-same/variable_*
Regardless of case for the variable or anything that comes after it
for it to 301 to the lower case version of /item-1/stays-the-same/variable - and always to the https://www. version.
The asterisk denotes anything, for example multiple paths, numbers, underscores etc
Any suggestions are very much appreciated.
Edit
"variable" is only letters or hyphens, upper or lower case.
"item-1" is static text and should always be in the end URL , even if it wasn't there as in the first two examples.
Everything after the variable is discarded, any trailing / or _ as well.

UPDATE: Several changes made to the rule/conditions to allow an all lowercase variable and to enforce the /item-1 prefix on the resulting URL-path. The part of the URL-path after the variable is discarded - something is always discarded.
Try the following (requires Apache 2.4):
RewriteCond expr "tolower(%{REQUEST_URI}) =~ m#^(?:/item-1)?/([^/] /[a-z-] )[/_]#"
RewriteCond %{HTTP_HOST}@%1 ^(?:www\.)?(. ?)\.?@(. )
RewriteRule ^(item-1/)?stays-the-same/([a-z-] )[/_] https://www.%1/item-1/%2 [NC,R=301,L]
The RewriteRule pattern establishes whether the requested URL-path matches one of the possible URLs and the variable contains only letters or hyphens and at least one of those letters is uppercase. The NC flag ensures this is a case-insensitive match, so the variable can be upper/lowercase.
The first condition then converts the URL-path to lowercase. The part of the lowercased URL-path up to and including the variable only is captured (excluding the optional /item-1 prefix), which is passed to the following condition in the %1 backreference.
The second condition then extracts the part of the hostname, less the www. prefix (if any) which is stored in the %1 backreference (again) and passes the lowercased URL-path (from the first condition) on to the following rule in the %2 backreference.
Note that the %2 backreference in the substitution string (that represents the URL-path) now excludes the slash prefix, so the slash is now included in the substitution string - I think this is more readable than including the slash as part of the backreference (as it was previously).
The /item-1 prefix needs to be hardcoded in the substitution string since this is optional in the requested URL-path.
You could simplify this and hardcode the www hostname instead and avoid the second condition. For example:
RewriteCond expr "tolower(%{REQUEST_URI}) =~ m#^(?:/item-1)?/([^/] /[a-z-] )[/_]#"
RewriteRule ^(item-1/)?stays-the-same/([a-z-] )[/_] https://www.example.com/item-1/%1 [NC,R=301,L]
This uses the backreference %1 directly from first condition in the substitution string.
Test first with a 302 (temporary) redirect to avoid potential caching issues and make sure the browser cache is cleared before testing.
