Brief Summary:

Non-randomized, multi-centre, open label, uncontrolled, multiple dose, phase IIa study.

A total of 18 patients diagnosed with acute myeloid leukaemia (AML) scheduled for chemotherapy and expected to be neutropenic (<500 Absolute neutrophil count (ANC)/µl) for >10 days will be treated. F901318 will be given in conjunction with fluconazole or posaconzaole in order to assess safe treatment regimens for both combinations.


Condition or disease Intervention/treatment Phase
Acute Myeloid Leukemia Drug: F901318 with fluconazole low dose Drug: F901318 with fluconazole high dose Drug: F901318 with posaconazole Phase 1 Phase 2

Detailed Description:

'F901318 has potent in vitro efficacy against Aspergillus spp. including azole-resistant strains and consistent efficacy in in vivo mouse models of infection. F901318 is active by both oral and intravenous routes of administration in preclinical efficacy studies.

Non-clinical studies and phase I clinical trials show that F901318 has a good overall safety profile and limited potential for drug-drug interactions. F901318 exhibits a highly promising profile which can potentially address the critical treatment requirements for invasive Aspergillus infections in a changing clinical environment in which new classes of antifungals are needed.

This phase IIa study aims to confirm PK and safety information of F901318 from phase I and bridge them to a neutropenic AML patient population, which represents the main population for future efficacy trials. Coadministration of fluconazole or posaconazole will allow recognizing potential factors of suboptimal F901318 exposure without the risk of fatal disseminating infection.'

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Participating patients need to fulfil all of the following criteria:

    1. Patients diagnosed with AML and entering treatment of chemotherapy.
    2. Patients are expected to be neutropenic (ANC <500/µl) for >10 days.
    3. Provision of written informed consent prior to any study specific procedures.
    4. Ability and willingness to comply with the protocol.
    5. Patients aged over 18 years.
    6. Patients with body weight ≥60 kg
    7. Group F only: patient receives according to local clinical standard either

      • no fungal prophylaxis or
      • only topical fungal prophylaxis (e.g. Ampho moronal®) or
      • fluconazole as routine fungal prophylaxis
    8. Group P only: patient receives posaconazole as fungal prophylaxis according to local clinical standard

Exclusion Criteria:

  • Any of the following will exclude a patient from the study:

    1. Documented lung infiltrate at screening.
    2. Evidence for active fungal infection, such as documented serum GMI ≥0.5 at screening (within 5 days before study start)
    3. Current IFD or prior history of IFD or patients who received systemic antifungal therapy for proven or probable IFD in the last 12 months.
    4. Patients who received any systemic antifungal therapy for more than 72 hours immediately prior to first administration of study medication. Echinocandins, posaconazole (group P, see also inclusion criterion 8), and topical polyenes or nystatin are acceptable.
    5. Concomitant exposure to phenobarbital and long acting barbiturates, triazolam, carbamazepine, phenytoin, pimozide, cisaprid, efavirenz, ritonavir, rifabutin, rifampicin, ergot alkaloids (ergotamine, dihydroergotamin), ibrutinib, idelalisib, vinca alkaloids, digoxin, dofetilide, quinidine, St. John´s wort, everolimus, sirolimus, astemizole, terfenadine, methadone, alfentanil, fentanyl and other structurally related opiates, warfarin (see also section 8.8 for details).
    6. Documented prolongation of the QTc interval (>450 ms).
    7. Concomitant medication that prolongs QT interval (except for cytostatic drugs used during chemotherapy, such as mitoxantrone).
    8. Any other 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.
