What a regulator's shortage notice actually authorises — what changed since

Solved
Solved by r.vukovic in post #4
Narrowing post #3, because the general version has more than one answer. If you can confirm or contradict a position for your own region, please date the answer. An undated regional claim is the least useful thing in this category. That is the version I would defend. It is not the version I started with.

The question in the title: What a regulator's shortage notice actually authorises — what changed since I will give what I have already checked below so nobody repeats it.

Asking what a regulator's document actually says, since the summaries of it disagree.

I have the primary document open and two secondhand accounts of it that cannot both be right. The primary document is narrower than either.

My question is whether I am reading the scope of it correctly, and what the correct reading rules out as well as what it permits.

Where a claim about legality is made here, the useful follow-up is which instrument it rests on. Most such claims turn out to rest on a forum post.

Everything in the opening post holds. The case it does not cover is the one I have.

Post-authorisation safety commitments are public and are one of the more useful sources for what a regulator considered uncertain at approval.

A regulator's public assessment report is usually the single best free source on a compound's evidence base, and it is almost never cited here.

This is the version I would want a new member to read first.

Nothing in this subcategory is legal advice, and the members who work in regulated environments are the most careful to say so.

I am aware this is the third time this month I have made this point.

Generic or biosimilar entry depends on patent and exclusivity positions that are jurisdiction-specific and are frequently misreported.

The arithmetic in post #7 is right; the assumption feeding it is the part to check.

An indication approved for one age range does not extend to another, and paediatric extensions are separate decisions with separate evidence.

On post #7 — agreed on the reasoning, with one qualification.

Noting that I have skin in this question and have tried to discount for it.

This follows post #12 rather than contradicting it.

Worth separating two things that post #12 runs together.

The right answer here may simply be that it has not been measured.

I read post #14 twice before replying, because I had assumed the opposite.

An indication approved for one age range does not extend to another, and paediatric extensions are separate decisions with separate evidence.

Taking post #16 at face value and following it one step further.

Generic or biosimilar entry depends on patent and exclusivity positions that are jurisdiction-specific and are frequently misreported.

Anyone with a larger sample, please post it.

This is where my knowledge stops and I would rather mark the edge than blur it.

Post #16 is the version of this I will quote in future. One addition.

An indication approved for one age range does not extend to another, and paediatric extensions are separate decisions with separate evidence.

The variance between people here is larger than the effect being discussed.

Where a regulator publishes a decision summary, that document usually contains the reasoning and is far more informative than the announcement.

I would treat that as a working assumption and revisit it.

On balance I think that is right, and I would not bet much on it.

That is consistent with mine, for whatever one more account is worth.

Post #24 describes the usual case. This is about the unusual one.

If you can confirm or contradict a position for your own region, please date the answer. An undated regional claim is the least useful thing in this category.

I would rather be precise about what I do not know than vague about what I do.

Adding the measurement that post #24 says would settle it.

Shortage notifications are published by several regulators and are the authoritative source for a question this community usually answers from anecdote.

The literature is thinner on this than the confidence in the thread implies.
