About this study

Official title: A SINGLE ARM, PROSPECTIVE, MULTI-CENTER STUDY TO EVALUATE SAFETY AND EFFICACY OF ISAVUCONAZOLE FOR PRIMARY TREATMENT OF CHINESE PATIENTS WITH INVASIVE FUNGAL DISEASE (IFD) CAUSED BY ASPERGILLUS SPECIES OR OTHER FILAMENTOUS FUNGI

This study is a post-approval commitment study, and is designed to further evaluate the safety and efficacy of isavuconazole in a relatively larger Chinese population who will receive isavuconazole treatment in a post-marketing setting.

This is a single arm, prospective, multi-center study. This study is seeking Chinese patients with proven, probable or possible Invasive Fungal Disease (IFD) caused by Aspergillus species or other filamentous fungi. All the participants will receive isavuconazole treatment. The longest treatment duration in this study is 84 days (up to 180 days for participants diagnosed with IM).

The primary objective is to characterize the safety and tolerability of isavuconazole through observing the treatment emergent adverse events.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Treatment Emergent Adverse Events (TEAEs)

    An adverse event (AE) was any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. A TEAE was an AE that started on or after the first administration of study intervention until 28 days after last dose of study intervention. AEs included both serious (SAE) and all non-serious adverse events (non-SAEs).

    Measured: From start of study intervention on Day 1 up to 28 days after last dose of study intervention (For Isavuconazole IA group: approximately up to 112 days, for Isavuconazole IM group: approximately up to 208 days)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Isavuconazole in people with Invasive Fungal Disease, run by Pfizer at 14 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 27 May 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Treatment Emergent Adverse Events (TEAEs) (time frame: From start of study intervention on Day 1 up to 28 days after last dose of study intervention (For Isavuconazole IA group: approximately up to 112 days, for Isavuconazole IM group: approximately up to 208 days)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 May 2026.
