Is sancuso a patch?

See the DrugPatentWatch profile for sancuso

What is Sancuso?

Sancuso is an onapristone, fentanyl transdermal patch, used for the management of chemotherapy-induced nausea and vomiting (CINV) in adult cancer patients receiving highly and moderately emetogenic chemotherapy [1]. The patch is placed on the stomach or lower back, providing a continuous delivery of opioid medication to help alleviate symptoms of nausea and vomiting [1].

Is Sancuso a traditional transdermal patch?

Sancuso is a single-use, pre-activated, adhesive transdermal patch [1]. The patch is not a traditional transdermal patch in the sense that it is not a passive, static delivery system. Instead, Sancuso utilizes an active ion-transport mechanism to drive the release of onapristone, fentanyl, and additional ingredients [1] throughout the 72-hour treatment duration. This active system aims to enhance and maintain steady-state plasma concentrations of the active ingredients.

Key differences from traditional patches

Sancuso has an additional component of onapristone, which is a selective progesterone receptor modulator (SPRM). This ingredient is used in combination with fentanyl to target and reduce chemotherapy-induced emesis. Traditional transdermal patches primarily rely on the sustained release of their active pharmaceutical ingredients [2].

Comparison with other transdermal patches

Sancuso is not equivalent to other popular transdermal fentanyl patches, such as Duragesic, which require activation before use. Sancuso is specifically designed for the management of CINV, providing a unique combination of onapristone and fentanyl in a single-use patch.

Patent information

The Sancuso patent, assigned to DureCT Corporation, expires in 2025 [${index} 3]. The patent protection covers the composition, formulation, and delivery mechanism of Sancuso [${index} 3].

Summary

The extracted claims contain multiple direct contradictions to the provided Sancuso label (granisetron transdermal system) including incorrect active ingredients, mechanism, administration location, and delivery system description. Additionally, no label-critical safety sections (contraindications/boxed warnings/warnings-precautions/specific populations) are evaluated, so full FDA-label adherence cannot be verified.

Important Omissions

No evaluation of label-critical safety sections (contraindications, boxed warnings, warnings/precautions, drug interactions, adverse reactions, or use in specific populations such as pediatrics/elderly/renal/hepatic impairment) is present in the provided audit output.
Importance: High
Label-defined administration timing (e.g., patch applied 24 to 48 hours before first chemotherapy dose) and duration context (patch kept in place for 7 days; regimen up to 5 consecutive days) are not assessed against the extracted claims.
Importance: Moderate

Safety Assessment

Potential Patient Risk: High
The extracted claims include multiple high-severity contradictions to the product identity and delivery/mechanism, plus incorrect anatomical placement (stomach/lower back vs upper outer arm). These could materially mislead about the drug and how/where to apply the patch.

Regulatory Assessment

Recommendation

Not Aligned

Primary Issue
Multiple direct contradictions to the label’s described active ingredient (granisetron) and patch administration site/mechanism; several claims rely on information not present in the provided label sections.

Suggested Improvement
Replace all onapristone/fentanyl and ion-transport/72-hour mechanism claims with label-supported granisetron transdermal identity and the provided administration instructions (upper outer arm; not on red/irritated/damaged skin), and evaluate remaining FDA label safety sections before final compliance claims.
