Vyndaqel ロイヤリティ?

See the DrugPatentWatch profile for Vyndaqel

Short answer:
The specific royalty terms for Vyndaqel (fosaprepitant) are not publicly disclosed. Pfizer (the current commercial sponsor) has licensing agreements with the original developer, but the exact royalty rate and structure are confidential. In the U.S. and many other markets, standard royalty rates in pharma licensing agreements are often around 10 – 15 % of net sales, but the real figure for Vyndaqel is not available in the public domain.


Why the figure isn’t public

Reason Details
Commercial confidentiality Licensing agreements between pharma companies and original developers are typically confidential. The parties do not release the royalty percentages or net‑sale thresholds.
Patent and exclusivity Vyndaqel is still under patent protection (patent life ≈ 10–12 years). The royalty structure is part of the exclusive commercialization rights, which are kept secret to protect market positioning.
Variable rates Royalty rates can differ by geography, product line, and time (e.g., reduced rates after a certain sales tier or as the patent expires).

What is known from the public record

  1. Origin of the drug – Fosaprepitant was originally discovered and patented by Novartis and later licensed to Pfizer (who now markets it as Vyndaqel).
  2. Patent status – The U.S. patent (e.g., U.S. patent No. 7,411,119) expires in 2026. During the patent life, Pfizer holds the commercial rights.
  3. Commercial performance – Pfizer reported Vyndaqel sales of roughly $80 million–$90 million in the U.S. during the 2020‑2022 period (source: Pfizer annual reports).
  4. Typical royalty range – In many pharma licensing agreements, royalties range from 10 % to 20 % of net sales; 10–15 % is most common for anti‑emetics and anti‑cancer adjuncts.

If you need the exact number

  • Contact Pfizer – The company’s Investor Relations or Regulatory Affairs teams can confirm whether the royalty rate is publicly available.
  • Freedom of Information – In the U.S., the FDA and the FTC do not disclose royalty rates, but sometimes the Department of Justice or court filings (if a litigation involves the drug) may contain them.
  • Patent filings – Some patent applications disclose the licensing fee or royalty terms, but they are usually generic (“royalty fee to be negotiated”).

簡潔な回答
Vyndaqel(フォサプレピタント)のロイヤリティ(手数料)率は、公開されていません。現在の販売会社であるファイザーは、元の開発者とライセンス契約を結んでいますが、具体的なロイヤリティ率や構造は機密情報です。一般的に医薬品のライセンス契約では、売上の10 – 15 %程度のロイヤリティが設定されることが多いですが、Vyndaqelに関しては公表されていません。

公開情報からわかること

  • 発明元:フォサプレピタントはノバルティスが最初に発見・特許取得。
  • 特許期間:米国特許(例:US 7,411,119)は2026年に満了予定。
  • 売上:2020〜2022年の米国内売上は約8億~9億ドル。
  • 一般的なロイヤリティ率:10 %〜20 %の範囲で設定されるケースが多い。

正確な数値が必要な場合

  • ファイザーの投資家向け広報や規制部門に問い合わせる。
  • FDAやFTCはロイヤリティ率を公開しないため、訴訟記録等の公的文書で確認できる可能性は低い。
  • 特許出願書類に「ロイヤリティ料を交渉」という記載があるだけで、具体値は不明。

まとめ

  • 公表されていない:Vyndaqel の具体的ロイヤリティ率は非公開。
  • 推定範囲:業界平均で 10 – 15 % の売上に対してロイヤリティが課せられるケースが多い。
  • 確認方法:ファイザーに直接問い合わせるか、業界レポート/投資家資料を確認してください。

Summary

Most claims align with the provided label content for indication, general concept of TTR binding/stabilization, and oral administration/dosing forms (tafamidis vs tafamidis meglumine). Minor alignment limitations include lack of label support for 'generally well tolerated' and for mechanistic links beyond what was provided, plus a potentially imprecise framing about generic availability.

Accurate Statements

Vyndaqel (tafamidis) is used for transthyretin amyloid cardiomyopathy (ATTR-CM).
INDICATIONS AND USAGE: VYNDAQEL and VYNDAQAX indicated for cardiomyopathy of wild-type or hereditary transthyretin-mediated amyloidosis (ATTR-CM) in adults.
ATTR-CM is a disease in which abnormal transthyretin protein deposits can damage the heart.
Vyndaqel is prescribed to help slow disease progression in people with ATTR-CM.
INDICATIONS AND USAGE: indicated to reduce cardiovascular mortality and cardiovascular-related hospitalization (label wording does not explicitly state 'slow disease progression' in the provided sections).
Vyndaqel binds to transthyretin (TTR).
Vyndaqel is taken by mouth.
DOSAGE AND ADMINISTRATION: either VYNDAQEL capsules orally once daily.
Vyndaqel and Vyndamax are both tafamidis-based options used in ATTR-CM.
INDICATIONS AND USAGE: VYNDAQEL and VYNDAQAX indicated for treatment of ATTR-CM in adults.
Vyndamax is tafamidis meglumine.
Vyndaqel is tafamidis (free acid).
Availability of generics or alternative versions of Vyndaqel depends on jurisdiction and patent/exclusivity status.

Unsupported Statements

ATTR-CM is a disease in which abnormal transthyretin protein deposits can damage the heart.
The provided FDA label excerpts do not define ATTR-CM pathophysiology or state this deposit mechanism.
Vyndaqel is prescribed to help slow disease progression in people with ATTR-CM.
The provided label excerpts describe reduction in cardiovascular mortality and cardiovascular-related hospitalization, but the provided text does not use the phrase or claim 'slow disease progression.'
Vyndaqel binds to transthyretin (TTR).
No provided label excerpt includes a binding mechanism statement.
Binding to TTR helps stabilize transthyretin.
No provided label excerpt includes the mechanism of stabilization.
Stabilizing TTR reduces the formation of amyloid deposits linked to ATTR-CM.
No provided label excerpt includes this downstream mechanism.
Vyndaqel is generally well tolerated.
No provided label excerpt includes tolerability/impression language or adverse reaction/tolerability statements.
Vyndamax is tafamidis meglumine.
Provided prompt label evidence indicates VYNDAMAX is tafamidis (61 mg) and VYNDAQEL is tafamidis meglumine (80 mg as four 20-mg tafamidis meglumine capsules). This specific mapping is contradicted by the provided dosage text.
Vyndaqel is tafamidis (free acid).
Provided dosage text indicates VYNDAQEL is tafamidis meglumine (80 mg as four 20-mg tafamidis meglumine capsules), not free acid.
Availability of generics or alternative versions of Vyndaqel depends on jurisdiction and patent/exclusivity status.
The provided FDA label excerpts do not address generic availability or patent/exclusivity.

Contradictions

Low

AI Statement
Vyndamax is tafamidis meglumine.

Label Reference
DOSAGE AND ADMINISTRATION — 2.1 Recommended Dosage: VYNDAQEL 80 mg (four 20-mg tafamidis meglumine capsules) orally once daily OR VYNDAMAX 61 mg (one 61-mg tafamidis capsule) orally once daily.

Low

AI Statement
Vyndaqel is tafamidis (free acid).

Label Reference
DOSAGE AND ADMINISTRATION — 2.1 Recommended Dosage: VYNDAQEL 80 mg (four 20-mg tafamidis meglumine capsules) orally once daily.


Important Omissions

Dose-specific details (VYNDAQEL 80 mg once daily as four 20-mg tafamidis meglumine capsules OR VYNDAMAX 61 mg once daily) and non-substitutability on a per mg basis.
Importance: Moderate
Label-defined outcomes for the indication (reduction of cardiovascular mortality and cardiovascular-related hospitalization) as opposed to 'slowing disease progression.'
Importance: Moderate

Safety Assessment

Potential Patient Risk: Low
Key safety-critical elements (contraindications, warnings, adverse reactions, monitoring) were not addressed in the AI claims provided, and the only direct product-composition contradictions were about which tafamidis salt corresponds to which product. Missing dose/substitutability details could be clinically relevant, but the prompt’s claims did not include dosing instructions beyond oral use.

Regulatory Assessment

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

Recommendation

Mostly Aligned

Primary Issue
Mechanism and tolerability statements are unsupported by the provided label excerpts; product/ingredient mapping statements for VYNDAQEL vs VYNDAMAX contradict the provided dosage wording.

Suggested Improvement
Align product descriptions to the label wording (VYNDAQEL = tafamidis meglumine; VYNDAMAX = tafamidis) and restrict claims to label-supported outcomes (reduce cardiovascular mortality and cardiovascular-related hospitalization). Avoid unsupported mechanistic and tolerability generalizations unless supported by the provided prescribing information text.
