Every mature brand eventually gets a lifecycle plan.
Some are real. Some are a new pack, the same message and a hope that nobody notices.
Doctors notice.
In my experience, an honest lifecycle plan climbs four steps, in this order.
Read the brand honestly. The sell-out trend, the share and what competitors are bringing, as they are. Not the version from the last review slide.
Find what is genuinely new. A new form, a new strength, an approved indication that patients actually need. If only the pack has changed, you are asking the field to sell a story.
Decide the effort it deserves. Invest, maintain or step back. Say which one, then resource it. Half-support is the most expensive choice, because it costs money and convinces nobody, including your own team.
Set the exit signals now. Agree, while things are calm, the point at which you will stop investing. Decided early, it is a plan. Decided late, it is a rescue.
The third step is where I see most plans soften. Nobody wants to be the one who says a brand should get less. But the people and budget it keeps are the ones your next brand needs.
“Extend a brand because patients need more of it, not because the budget does.”
