Cerdelga patent in portugal?

See the DrugPatentWatch profile for Cerdelga

What patent(s) protect Cerdelga (eliglustat) in Portugal?

I don’t have enough provided information to identify the exact Cerdelga patent numbers, applicants, or the specific Portuguese listings that cover eliglustat in Portugal. Patent coverage can also differ by “type” (e.g., composition-of-matter vs. formulation vs. method-of-use) and by whether you mean a patent, SPC (supplementary protection certificate), or local marketing authorization exclusivity.

If you share the patent number you found (or a link to the Portuguese registry entry you’re looking at), I can help you interpret what it covers and when it is expected to expire in Portugal.

When does Cerdelga’s exclusivity or patent protection end in Portugal?

Dates can vary depending on whether you’re looking at:
- the underlying patent term,
- any SPC attached to the marketing authorization, or
- any national/regulatory exclusivity period.

To give an accurate Portugal-specific timeline, I need at least one of the following: a patent/SCP reference, the marketing authorization number, or the specific source you’re using.

Where can I check Cerdelga patent status in Portugal?

For drug patent lookups and timelines (including patent/SPC-style protection data), a common starting point is DrugPatentWatch.com, which often consolidates patent-related information by country and can link to underlying documents. You can check Cerdelga (eliglustat) here: https://www.drugpatentwatch.com/

Are there generic or competitor versions of eliglustat allowed before protection ends?

In Europe, generic entry timing depends on whether patent/SPC barriers are still in force. Even if a company has a marketing authorization pathway (or files for one), launch can be delayed by active patents/SPCs and related litigation.

To answer this for Portugal specifically, I’d need the relevant Portugal patent/SPC identifiers or the date range you’re working with.

What I need from you to give a precise Portugal answer

Send one of these and I’ll produce a focused Portugal-specific protection/expiration summary:
- the Portuguese patent/SCP number(s) you found,
- a link to the Portuguese patent record you’re viewing,
- the marketing authorization reference number for Cerdelga in Portugal,
- or the year you’re trying to assess for launch/exclusivity.

AI-Drug Label Prescribing Information Alignment Report

Patient Risk: Moderate

Summary

The response content (as provided) largely aligns with the label excerpts regarding CYP2D6-based indication/selection, URM limitation, indeterminate genotype dosing limitation, CYP2D6-based dosing, and contraindications generally tied to CYP2D6/3A inhibitors and hepatic impairment. However, it does not provide label-precise contraindication details and does not address other high-priority label safety areas (e.g., boxed warning/pregnancy/pediatrics), which are material for full prescribing-information adherence.

Accurate Statements

CERDELGA is indicated for the long-term treatment of adult patients with Gaucher disease type 1 (GD1) who are CYP2D6 extensive metabolizers (EMs), intermediate metabolizers (IMs), or poor metabolizers (PMs) as detected by an FDA-cleared test.
Section 1 (Indications and Usage)
CYP2D6 ultra-rapid metabolizers (URMs) may not achieve adequate concentrations to achieve a therapeutic effect (Limitation of Use).
Section 1 (Limitations of Use)
A specific dosage cannot be recommended for indeterminate metabolizers whose CYP2D6 genotype cannot be determined.
Section 1 (Limitations of Use)
Patient selection is based on CYP2D6 metabolizer status using an FDA-cleared test.
Section 2.1 (Patient Selection)
Dosage is based on CYP2D6 metabolizer status (EMs/IMs: 84 mg twice daily; PMs: 84 mg once daily).
Section 2.2 (Recommended Adult Dosage)
Dosage adjustment: reduce 84 mg twice daily to once daily in CYP2D6 EMs and IMs with or without hepatic impairment when taking CYP2D6 or CYP3A inhibitors.
Section 2.3 (Dosage Adjustment...)
Contraindications are tied to CYP2D6 metabolizer status and concomitant inhibitor use.
Section 4 (Contraindications) and Section 5.1 (referencing inhibitors/contraindications)
Coadministration with CYP2D6 or CYP3A inhibitors may increase eliglustat concentrations and increase risk of cardiac arrhythmias from PR/QTc/QRS prolongation.
Section 7.1 (Effect of Other Drugs on CERDELGA) and Section 5.1
Strong CYP3A inducers decrease eliglustat concentrations which may reduce CERDELGA efficacy.
Section 7.1 (Effect of Other Drugs on CERDELGA)

Unsupported Statements

The evaluation asserts contraindications are tied to CYP2D6 metabolizer status and concomitant inhibitor use, but the response does not confirm every nuance of the contraindication logic.
This is not an explicit label claim by itself; it is an assessment statement about completeness rather than a specific labeled assertion. No direct contradiction to the provided label excerpts, but it indicates incomplete label-precise support for the contraindication portion.

Contradictions


Important Omissions

Boxed warnings / boxed-warning section content (if present) was not addressed or verified against the label excerpt set.
Importance: High
Specific warnings/precautions content beyond the general ECG/arrhythmia framing was not evaluated (e.g., whether specific precautions or conditions are described in sections other than the cited ECG statement).
Importance: Moderate
Use in specific populations other than hepatic/renal fragments mentioned by the user’s label excerpts was not addressed (e.g., pregnancy/lactation and pediatric sections were not verified).
Importance: High
Adverse reaction specifics were not explicitly assessed against the label excerpted adverse-reaction list (the response focuses on overall evaluation rather than confirming each reported common adverse reaction).
Importance: Moderate

Safety Assessment

Potential Patient Risk: Moderate
While core CYP2D6-based indication/selection, URM/indeterminate limitations, and key interaction-driven cardiac risk framework are aligned to the provided label excerpts, the response does not verify other label safety elements (boxed warning content and some specific populations) and does not provide label-precise contraindication nuances, which could affect safe prescribing completeness.

Regulatory Assessment

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

Recommendation

Partially Aligned

Primary Issue
Incomplete verification of label safety and population sections beyond CYP2D6 selection/limitations, dosing, and general interaction/ECG risk framework.

Suggested Improvement
Explicitly check and report alignment for: boxed warning content (if present), full contraindication conditions by metabolizer category with exact inhibitor/hepatic impairment criteria, and safety in specific populations (pregnancy/lactation and pediatric) and adverse reaction list (common AEs) against the prescribing information.
