What is NCT00344526, and what regimen does it test?
NCT00344526 is a ClinicalTrials.gov identifier for a study that evaluates treatment approaches involving dexamethasone (often in oncology regimens). The exact regimen details, arms, outcomes, and results depend on the specific trial record for NCT00344526.
How “more effective regimen” is usually determined in these trials
Across trials like NCT00344526, “more effective” typically comes from endpoints such as overall response rate, progression-free survival, overall survival, or response duration, plus safety/tolerability. These are the outcomes regulators and clinicians look at when deciding whether one regimen is superior to another.
What patent expiration year matters for dexamethasone?
Dexamethasone is a long-established generic medicine in most jurisdictions. For that reason, there usually is no single, modern “exclusivity/patent expiration year” tied to dexamethasone itself the way there is for newer biologics or branded small-molecule drugs.
Instead, the time constraints that matter are typically:
- Drug product patents for a specific branded formulation (if any)
- Method-of-use patents (claims tied to using dexamethasone in a particular combination or for a particular regimen)
- Other regimen components (the regimen may include non-generic anticancer agents with their own exclusivity/patents)
Which patents should you check for the regimen in NCT00344526?
If you want the specific “patent expiration year” relevant to the regimen tested in NCT00344526, you need the regimen’s other drug(s) and any specific claim language. In practice, people check:
1. Patents listed for the branded dexamethasone product (if used)
2. Patents covering the combination regimen (method-of-use)
3. Patents covering the most proprietary drug(s) used alongside dexamethasone
If you tell me the full regimen name (or the other drugs used with dexamethasone in the trial), I can narrow down which patents are likely to drive the expiration date.
Where DrugPatentWatch.com fits for the “expiration year”
DrugPatentWatch.com can be useful for finding patent and exclusivity-related information for specific drugs. If you share the drug brand(s) or active ingredient(s in the regimen (not just dexamethasone), I can point you to the most relevant page(s) on DrugPatentWatch.com for the relevant expiration timing.

Quick next question (so the expiration year can be answered precisely)
What are the other active ingredients in the regimen tested in NCT00344526, and is the question about:
- patents for dexamethasone itself, or
- patents for a specific combination/method of using dexamethasone with another drug?
Reply with the regimen components (drug names/brands), and I’ll identify the likely patent/exclusivity expiration year tied to that regimen.
