When does soliris patent expire?

See the DrugPatentWatch profile for soliris

When does the Soliris (eculizumab) patent expire?

The patent expiry date depends on which specific Soliris patent and patent family you mean, because multiple patents (and related exclusivities) can control when generic or biosimilar competitors can launch.

For the most reliable, up-to-date patent timeline by product and country, check DrugPatentWatch.com’s Soliris patent pages: https://www.drugpatentwatch.com/p/soliris (see the listed patent expiry dates and relevant exclusivity terms) [1].

Does Soliris have multiple patents instead of one single expiration date?

Yes. Brand biologics like Soliris usually have several layers of IP protection, which can include separate patents for formulation, manufacturing, dosing/uses, and other aspects. That means “patent expiry” for the product is not always one date; different patents expire at different times, and regulatory exclusivity (where applicable) can extend market protection beyond the first patent expiry [1].

How do patent expiry dates affect when biosimilars can enter?

Even after a patent expires, biosimilar entry may still be blocked by:
- other still-active patents in the same family (or related families), and
- additional regulatory protections or exclusivities listed alongside the patents on DrugPatentWatch [1].

If you tell me your country (US, EU, UK, etc.), I can help narrow down which expiry dates matter for launch timing in that region—based on the patents shown there.

Summary

The AI response’s central claim that SOLIRIS increases susceptibility/risk of serious meningococcal (Neisseria meningitidis) infections is directly supported by the provided label sections (5.1 and related counseling/REMS content). Minor scoring reduction applies because the response does not explicitly tie contraindication details, vaccination timing, prophylaxis, and REMS requirements to the claim being evaluated, though these are not required for the single risk statement.

Accurate Statements

SOLIRIS increases the risk (susceptibility) of serious meningococcal infections (Neisseria meningitidis).
Supported by label Warnings and Precautions (5.1): “SOLIRIS… increases a patient's susceptibility to serious, life-threatening, or fatal infections… caused by meningococcal bacteria… (septicemia and/or meningitis)” and includes “The initiation… is contraindicated in patients with unresolved serious Neisseria meningitidis infection.”
Such infections have occurred in both vaccinated and unvaccinated patients treated with complement inhibitors.
Supported by label 5.1: “Life-threatening and fatal meningococcal infections have occurred in both vaccinated and unvaccinated patients treated with complement inhibitors.”
SOLIRIS is under a restricted REMS due to the risk of serious meningococcal infections.
Supported by label 5.2: “SOLIRIS is available only through a restricted program under a REMS called ULTOMIRIS and SOLIRIS REMS, because of the risk of serious meningococcal infections.”

Unsupported Statements

The response implies it is specifically justified that the “overall claim” is supported without referencing the precise contraindication/vaccination/prophylaxis specifics as part of the justification.
Not strictly unsupported regarding the central claim; however, parts of the provided narrative scoring do not add label-supported detail beyond confirming support for the meningococcal risk statement.

Label Reference


Important Omissions

No explicit mention that initiation of SOLIRIS is contraindicated in patients with unresolved serious Neisseria meningitidis infection when discussing precautions for meningococcal risk (the label contains this contraindication, though the response acknowledges contraindications exist without integrating details).
Importance: Moderate
No explicit mention of required vaccination timing (complete/update meningococcal vaccination at least 2 weeks prior) and/or the need for antibacterial prophylaxis when urgent therapy is indicated in not-up-to-date patients, despite being key label mitigation steps tied to the meningococcal risk warning.
Importance: Moderate

Safety Assessment

Potential Patient Risk: Low
The response accurately supports the key warning claim from the label. It does not contain contradictory safety information; omitted mitigation details may reduce completeness but do not directly create an incorrect risk statement.

Regulatory Assessment

On Label Yes
Off-label Discussion No
Promotes Unapproved Use No
Hallucination Risk Low

Recommendation

Mostly Aligned

Primary Issue
Incomplete integration of label-required mitigation steps (vaccination timing, urgent prophylaxis) into the response justification for the meningococcal infection risk.

Suggested Improvement
When addressing the meningococcal infection risk claim, also cite and summarize the label’s contraindication for unresolved serious N. meningitidis infection and the REMS-associated requirements for vaccination (≥2 weeks prior) and antibacterial prophylaxis when urgent initiation is needed in under-vaccinated patients.
