Sugammadex invention date?

See the DrugPatentWatch profile for Sugammadex

When was Sugammadex invented?

Sugammadex, a selective relaxant binding agent used to reverse neuromuscular blockade caused by rocuronium and vecuronium, has its roots in a research project initiated in the 1990s by the Japanese pharmaceutical company, Organon, which is now a part of Merck & Co.

Early Development and Patents

The development of Sugammadex began around 1999-2000 [1]. The researchers at Organon filed their first patent for Sugammadex in 2000, and subsequent patents were granted in the following years [2]. The initial patent application focused on the synthesis of Sugammadex and its properties as a neuromuscular blocking agent antagonist.

Clinical Trials and Approval

After the initial patent filing, clinical trials for Sugammadex were initiated, showing the agent's efficacy in reversing rocuronium-induced paralysis [3]. In 2008, the U.S. Food and Drug Administration (FDA) approved Sugammadex for use in patients undergoing surgery, marking a significant milestone for the drug's development.

Why is the patent expiration relevant?

As for the patent expiration date, it is essential for pharmaceutical companies like Merck & Co. to monitor the exclusivity period of their drugs. The patent for Sugammadex likely expired in 2019, allowing other companies to develop biosimilars [4]. This information might be helpful for those searching for alternative options to Sugammadex.

Accurate Statements

Sugammadex is used to reverse neuromuscular blockade caused by rocuronium.
Supported by 1 INDICATIONS AND USAGE and 12.1 Mechanism of Action (reversal of blockade induced by rocuronium bromide).
Sugammadex is used to reverse neuromuscular blockade caused by vecuronium.
Supported by 1 INDICATIONS AND USAGE and 12.1 Mechanism of Action (reversal of blockade induced by vecuronium bromide).

Unsupported Statements

Sugammadex is a selective relaxant binding agent.
The provided label excerpts show complex formation with rocuronium and vecuronium and reversal of blockade, but do not verify the exact characterization 'selective relaxant binding agent' verbatim in the supplied text.
Development of Sugammadex began around 1999-2000.
No development timeline is provided in the available label sections.
Organon filed its first patent for Sugammadex in 2000.
No patent filing information is provided in the available label sections.
The initial patent application focused on the synthesis of Sugammadex.
No patent application content is provided in the available label sections.
The initial patent application focused on Sugammadex's properties as a neuromuscular blocking agent antagonist.
No patent application content is provided in the available label sections.
Clinical trials for Sugammadex were initiated after the initial patent filing.
No clinical trial initiation timing is provided in the available label sections.
Clinical trials showed efficacy of Sugammadex in reversing rocuronium-induced paralysis.
The provided excerpts do not include clinical trial outcomes/results; they only support mechanism/indication.
In 2008, the U.S. Food and Drug Administration (FDA) approved Sugammadex for use in patients undergoing surgery.
The label excerpt does not provide the approval year (only the surgical reversal indication is present).
The patent for Sugammadex likely expired in 2019.

Contradictions


Important Omissions

Boxed warnings, contraindications, dosing/administration instructions, and safety/monitoring details were not assessed because the provided excerpts did not include those label sections.
Importance: Moderate

Safety Assessment

Potential Patient Risk: Low
The only directly label-relevant clinical claims are about the indicated reversal of neuromuscular blockade from rocuronium/vecuronium, which are supported. The unsupported claims are historical/administrative (development, patents, approval year) and do not introduce dosing or contraindication changes.

Regulatory Assessment

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

Recommendation

Partially Aligned

Primary Issue
Several non-label-supported historical/patent/approval-year claims and one partially supported terminology claim ('selective relaxant binding agent').

Suggested Improvement
Limit claims to what is supported in the label excerpts provided (e.g., indication and mechanism) and remove or qualify historical/patent/approval-year assertions unless supported by the official prescribing information sections.
