Background summary
Invasive fungal (IA) infections due to resistant fungi cause substantial
morbidity and mortality when either not treated or when available therapy lacks
activity, especially in patients with reduced immune function. Invasive
aspergillosis in immunocompromised patients is a devastating illness with a
mortality that approaches 100% without effective therapy. Timely treatment of
IA with an effective modern drug may reduce mortality to approximately 20% at 6
weeks. When IA is resistant or becomes resistant to the azole antifungal
agents, mortality rates range between 50% and 100%, mortality rates that
approach those for untreated infection. The emergence of resistance threatens
the future use of the azoles and highlights the urgent need for new and
effective antifungal agents.
In addition to the emergence of resistance, currently available classes of
antifungal treatment are limited by dosage forms, drug-drug interactions, and
significant adverse reactions.
Based on the nonclinical efficacy profile and on preliminary results of an
ongoing Phase IIb study, olorofim may offer an effective treatment for patients
with IA. 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 objective
This study has been transitioned to CTIS with ID 2024-513030-38-00 check the CTIS register for the current data.
To compare ACM at Day 42 following treatment with olorofim versus treatment
with AmBisome® followed by SOC in the intent-to-treat (ITT) population of
patients with IFD caused by proven IA at any site or probable lower respiratory
tract disease (LRTD) Aspergillus species.
Study design
A Phase III, adjudicator-blinded, randomised study to evaluate the efficacy
and safety of treatment with olorofim versus treatment with AmBisome®
followed by standard of care (SOC) in patients with invasive fungal disease
(IFD) caused by Aspergillus species.
Intervention
Subjects will be randomized 2:1 to olorofim versus AmBisome® .
Olorofim:
Treatment: Oral intake of 30mg coated tablets
starting dose: 150 mg (5 tablets) taken twice for 1 day
maintenance dose: 90 mg (3 tablets), taken twice per day for up to 12 weeks
Both the starting and maintenance doses will be taken every 12 hours
The maximum dose is 150 mg (5 tablets) taken every 12 hours
AmBisome®:
Treatment: intravenously, 3mg AmBisome® per kilogram of bodyweight once per
day for at least 10 days
Study burden and risks
The length of subject participation in this study will depend on if and how
quickly the infection responds to the medication given in this study. The
maximum duration of participation is expected to be approximately 18 weeks.
Subjects will have up to 18 study visits during the study. If the infection
clears up during the treatment period, subject participation will be shorter,
and there will be fewer study visits. A visit will take up to 6 hours.
Subjects will need to come to the hospital more often than they would usually,
and have additional tests. These include physical examination, X-ray/CT/MRI
imaging, ocular assessment, ECGs, pregnancy tests, urine tests and blood
tests. Collection of a small piece of the infected area or fluid from the
infected area to determine which fungus is causing your infection, possibly
there will be a bronchoscopic assessment if the infection is in the lungs.
Subjects will be asked to complete questionnaires and fill a patient dosing
diary. Subjects must avoid pregnancy. Subjects must be careful when driving or
using machines (due to the risk of dizziness). Participants who agree to take
part in the ECG sub-study, will be asked to wear a device called a Holter
monitor at certain time points during the main study.
Risk of side effects. The following side effects that were reported by some
healthy subjects who received the study drug as multiple oral doses during the
studies: Dizziness, Nausea or feeling sick, Increased liver enzymes, Back pain,
Throat irritation or pain, Diarrhea , Upper respiratory tract infection, Dry
skin, Blurred vision, Stomach pain or bloating, Constipation, Dry lips,
Vomiting or being sick, Chest pain, Symptoms of influenza, Bruising, Pain when
urinating , Rash, Arm or leg pain, Feeling tired, Blocked nose. In addition,
the risk associated with exposure to X-rays.
Side effects of AmBisome®
Low magnesium, calcium, or sodium blood levels, leading to feeling tired,
confused, muscle weakness or cramps ,High blood sugar levels
Headache ,A faster heart rate than normal, Widening of the blood vessels,
causing low blood pressure and flushing, Breathlessness, Diarrhea, Stomach
pain, Rash , Chest pain , Back pain, Abnormal results for liver or kidney
function showing up in blood tests or urine tests
Based on the nonclinical efficacy profile and on preliminary results of an
ongoing Phase IIb study, olorofim may offer an effective treatment for patients
with IA.

Inclusion criteria
1. Male and female patients ages >= 18 years and weighing >= 30 kg, [*] or
Patients unable to write and/or read but who fully understand the oral
information given by the Investigator.
2. Patients with proven IA at any site or probable LRTD IA per
EORTC/MSG 2019 criteria as adapted for this study (see Appendix 2) and where
the duration of specific therapy for this episode of IA has been <= 28 days. For
purposes of this inclusion, the duration of specific therapy includes any
mould-active therapy given for this episode of IA whether subsequently judged
potentially effective or not.
3. Patients requiring therapy with an antifungal agent other than a
mould-active azole and who have had <= 96 hours of potentially effective prior
therapy. Potentially effective prior therapy includes any agent to which the
infecting strain of Aspergillus is likely to be susceptible. There are no
exclusions or limitations on such agents (eg, AmBisome® is permitted) other
than their duration.
Patients must meet at least one of these criteria:
a) Proven or suspected azole resistance in patients who have had <= 96 hours of
potentially effective prior therapy [*]
b) Breakthrough infection on triazole prophylaxis: patients who have had any
duration of prophylaxis prior to the breakthrough but <= 96 hours of potentially
effective prior therapy.
c) Any other medical reason an azole is inappropriate for the patient at
screening. In all cases, patients must have had <= 96 hours of potentially
effective prior therapy
(potential for drug-drug interaction, previous history of azole intolerance)
d) Invasive aspergillosis refractory to triazole therapy in patients who have
had <= 28 days of prior therapy where refractory IA was defined per an
international expert meeting report
4. AmBisome® is an appropriate therapy for the patient.
a) For avoidance of doubt, prior therapy with an amphotericin B (eg, AmBisome®
or other) is not an exclusion provided that such prior therapy does not exceed
the rules for maximum duration of potentially effective prior therapy discussed
as part of Inclusion Criterion 3.
5. Ability and willingness to comply with the protocol.
6. Female patients must be non-lactating and at no risk of pregnancy [*]
7. Male patients with female partners of childbearing potential must either
totally abstain from sexual intercourse or use a highly effective means of
contraception.
For more details, please refer to the protocol.
Exclusion criteria
1. Women who are pregnant or breastfeeding.
2. Known history of allergy, hypersensitivity, or any serious reaction to any
component of the study drug (olorofim or AmBisome®).
3. Patients with only chronic aspergillosis, aspergilloma or allergic
bronchopulmonary aspergillosis.
4. Suspected mucormycosis (zygomycosis). Evidence for the presence of olorofim
non susceptible filamentous fungi such as Mucorales should be urgently followed
up. Increased vigilance for the possibility of mucormycosis (zygomycosis) is
required for suspected IA with negative baseline GM.
5. Patients with a known active second fungal infection of any type, other than
candidiasis being treated with fluconazole.
6. The requirement for ongoing use of echinocandin as Candida prophylaxis (for
avoidance of doubt, prior use of an echinocandin is permitted; if ongoing
prophylaxis for Candida is needed, then fluconazole must be an acceptable
choice [see Section 5.8.4.1, discussion of concomitant antifungal agents]).
7. Microbiological findings (eg, bacteriological, virological) or other
potential conditions that are temporally related and suggest a different
aetiology for the clinical features.
8. Patients with human immunodeficiency virus (HIV) infection who are currently
not receiving antiretroviral therapy. Patients with HIV infection receiving
antiretroviral therapy can participate in the study. In cases where HIV
infection is first diagnosed at the same time as the invasive fungal infection,
if antiretroviral therapy is commenced at the time of enrolment, then such
patients are eligible for enrolment.
9. Any known or suspected condition of the patient that may jeopardize
adherence to the protocol requirements or impede the accurate measurement of
efficacy (eg, neutropenia not expected to resolve, patients with uncontrolled
malignancy who are treatment refractory and receiving only palliative therapy).
10. with a concomitant medical condition that, in the opinion of the
Investigator, may be an unacceptable additional risk to the patient should
he/she participate in the study.
11. Patients previously enrolled in a study with olorofim/F901318.
12. Treatment with any investigational drug in any clinical trial within the 30
days prior to the first administration of study drug except for unblinded
protocols (eg, open-label oncological regimen variations or biologic studies).
Prior to enrolling patients who are on other open label studies it is the
site's responsibility to ensure that the study criteria for that study allow
for enrolment into this study.
13. Patients receiving treatment limited to supportive care due to predicted
short survival time.
14. Patients with a baseline prolongation of Fridericia's Correction Formula
(QTcF) >= 500 msec, or at high risk for QT/QTc prolongation.
15. Evidence of hepatic dysfunction with any of the following abnormal
laboratory parameters at screening (for avoidance of doubt, liver transplant
recipients may be enrolled if their laboratory parameters do not meet the
exclusions):
a) Total bilirubin >= 2 × upper limit of the normal range (ULN)
b) Alanine transaminase or aspartate transaminase (AST) >= 3 × ULN
c) Patients with known cirrhosis or chronic hepatic failure (regardless of
ALT/AST/total bilirub
16. Prohibited concomitant medications: concomitant administration of
inhibitors of human DHODH (teriflunomide and leflunomide) are prohibited.
There are currently no other absolutely prohibited concomitant medications or
vaccines, but there are medications with potentially significant DDIs, and the
management of potential interactions should be considered before study
enrolment.
17. Additional exclusion criteria required by local regulatory authorities.
