About this study
Official title: Phase III, Adjudicator-blinded, Randomised Study to Evaluate Efficacy and Safety of Treatment With Olorofim Versus Treatment With AmBisome® Followed by Standard of Care in Patients With Invasive Fungal Disease Caused by Aspergillus Species
The purpose of this study is to compare treatment with olorofim versus treatment with AmBisome® followed by standard of care (SOC) in patients with IFD caused by proven IA or probable lower respiratory tract disease Aspergillus species (invasive aspergillosis, IA).
Read the detailed description
The mortality rate in immunosuppressed patients with IA is high even with effective modern antifungal drug treatment. Intrinsic and acquired resistance to azoles and amphotericin B, the two most effective classes of treatment, have been identified in Aspergillus species and are linked to this increased mortality.
Currently marketed antifungal drugs have limitations including limited dosage forms, DDIs, and significant adverse reactions.
For patients with IA who do not respond to or cannot tolerate a triazole therapy, treatment options are even more limited.
Olorofim is an antifungal candidate with a novel mechanism of action offering activity against resistant organisms, differences in safety profile, along with oral dosing, predictable and reliable pharmacokinetic (PK) profile and limited potential for DDIs.
The present study is designed to compare the efficacy, safety, and tolerability of olorofim with that of AmBisome® followed by guideline-based hierarchy standard of care (SOC) in patients with IA whose infection is either refractory to or unsuitable for azole therapy.

| Study group | Role | What they receive |
|---|---|---|
| Olorofim | Active comparator | Olorofim versus AmBisome followed by Standard of Care (SOC) Receives: Drug: Olorofim |
| AmBisome | Active comparator | Olorofim versus AmBisome followed by Standard of Care (SOC) Receives: Drug: AmBisome® |
What is being measured
The primary outcome is the main question the study is designed to answer.
All-cause mortality
To compare all-cause mortality (ACM) at Day 42 following treatment with olorofim versus treatment with AmBisome® followed by standard of care (SOC) in the intent-to-treat (ITT) population of patients with Invasive Fungal Disease (IFD) caused by proven Invasive Aspergillosis (IA) at any site or probable lower respiratory tract disease (LRTD) Aspergillus species (invasive aspergillosis, IA).
Measured: Treatment Day 42
Secondary outcomes (9)
Adjudicated Assessment of Overall outcome
To compare the effects of treatment with olorofim versus treatment with AmBisome® followed by SOC on Data Review Committee (DRC)-adjudicated assessment of overall outcome in patients with proven IA or probable LRTD IA at Day 42, Day 84, and End of Treatment.
Measured: Day 42, Day 84, and End of Treatment (anytime during the study between first administration and Day 84)
Investigator-assessed overall response
Investigator-assessed overall response (integrating clinical, radiological, and mycological response).
Measured: Day 14, Day 28, Day 42, Day 84, EOT (End of Treatment - Maximum Treatment 84 days [± 7 Days]), and 4-week Follow-up (FU).
To compare the effects of treatment with olorofim versus treatment with AmBisome® followed by SOC on Galactomannan index.
The Sponsor's expert advisors suggested that an appropriate rule would be a failure of the GM to decline from baseline. The experts also state that they have seen very significant variation on retesting of both BAL and serum GM samples and believe it is more appropriate to state a fixed reduction of ≥ 1.0 units than any percentage reduction.
These rules are used for changes in GM that document failure of therapy:
- Serum: After 8 or more days of treatment, serum GM has neither (1) fallen by ≥ 1 unit nor (2) to < 0.5 based on measurements taken at least 8 days apart.
- BAL: After 8 or more days of treatment, positive GM from BAL in a patient with a previous BAL test that did not meet the definition of positive (too low or entirely negative) without regard for the interval of time between samples.
Measured: Day 14, Day 28, Day 42, Day 84, EOT (End of Treatment - Maximum Treatment 84 days [± 7 Days]) and 4-week Follow-up (FU)
To collect additional olorofim and the disproportionate metabolite H26C pharmacokinetic (PK) data for inclusion in a Population PK model
To collect plasma concentration of olorofim and H26C metabolic for for PK analysis (pre-dose and intensive PK). No non-compartmental PK analysis will be performed on the data relating to pre-dose samples and intensive PK samples, apart from data collected from selected regions, which will be reported separately. All relevant olorofim data will be provided to support population PK modelling, which will be reported separately.
Measured: Day 10, Day 14, Day 21, Day 28, Day 42, Day 56, Day 70, Day 84, and at EOT (End of Treatment - Maximum Treatment 84 days [± 7 Days])
Data Review Committee's Assessment of Patient Mortality
Study data will be independently assessed by a blinded DRC consisting of independent experts in the diagnosis and management of IA, providing an independent adjudication of each patient's mortality based on the survival status collect at time frame.
Measured: Day 42 and 84 and EOT (End of Treatment - Maximum Treatment 84 days [± 7 Days])
Diagnosis of a secondary fungal infection
To compare incidence of a secondary fungal infection when patients treated with olorofim versus treatment with AmBisome followed by SOC.
Measured: at any time through End Of Treatment
Quality of life as measured by the 5 Level 5 Dimension (EQ-5D-5L) at Baseline
To assess patient's quality of life measured by the 5-Level 5-Dimension EuroQol Group Health-related Quality of Life Questionnaire (EQ-5D-5L) in both treatment groups
Measured: Days 14 and EOT (End of Treatment - Maximum Treatment 84 days [± 7 Days])
Survival status
All-cause mortality will be assessed using survival status at time frame.
Measured: Day 42, Day 84, and End Of Treatment and at the 4 weeks ± 7 days FU
Safety Assessment
To monitor incidence of Adverse Events and Serious Adverse Events in both treatment arms (Olorofim or AmBisome followed by Standard of Care).
Measured: up to the Day 84 and 4-week Follow-up (FU)

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Olorofim and AmBisome® in people with Invasive Aspergillosis, run by F2G Ltd at 143 sites in 21 countries.
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 4 inclusion and 10 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 8 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 143 sites in United States, China, Japan, Italy, France and 16 more countries. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
All-cause mortality (time frame: Treatment Day 42). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05101187, which also lists 1 linked publication.
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 8 Oct 2026.
