NCT06860334 | NOT YET RECRUITING | Crimean-Congo Hemorrhagic Fever

UMIT-2 - Adaptive Phase IIb Platform Trial to Determine the Efficacy and Safety of Therapeutics for CCHF
Sponsor:

Liverpool School of Tropical Medicine

Brief Summary:

CCHF has a wide geographical distribution with cases mainly occurring in Asia, the Middle East, South-Eastern Europe and Africa. Since its emergence in 2002, Turkiye has been the epicentre of activity worldwide reporting up to more than 1000 cases annually. CCHF case management relies on the provision of optimised supportive care; therapeutic options lack a robust evidence base The UMIT-2 Trial (UMIT = 'Hope' in Turkish) will be the first large randomised controlled trial of novel therapeutics in CCHF, undertaken in multiple trial sites in Turkiye and Iraq. It uses an efficient adaptive platform design (Phase IIb), focussed on antiviral efficacy with interim monitoring to introduce new arms and allow early stopping for futility, efficacy, or safety

Condition or disease

Crimean-Congo Hemorrhagic Fever

Intervention/treatment

Favipiravir

Ribavin

Optimised Standard of Care

Phase

PHASE2

Detailed Description:

This will be a 1:1:1 randomised open-label phase 2b trial of Favipiravir (IV \& PO) and Ribavirin (IV \& PO) vs optimised standard of care in CCHF aimed at evaluating virological efficacy. This is an adaptive multi-arm Phase II platform for patients with CCHF. Key design features are: Treatment arms can be added or removed. Shared standard of care (SoC, control) arm so that a greater proportion of more patients receive experimental therapeutics. Eligibility to randomisation to specific treatment arms is based on treatment specific inclusion/exclusion criteria and all comparisons to SoC are within the same eligibility set and concurrent randomisation. Timing of interim analyses flexible to make use of the seasonality of CCHF to ensure they take place during low recruitment periods.

Criteria
Inclusion Criteria
  • Adult in-patients (≥18 years)
  • Laboratory confirmed CCHF infection by positive polymerase chain reaction (PCR) test within 5 days prior to randomisation
  • Capacity to provide informed consent signed by study patient or legally acceptable representative (for illiterate individuals).
  • Women of childbearing potential (WOCBP) and male patients who are sexually active with WOCBP must agree to use a highly effective method of contraception (as outlined in section 5.4 below) from the first administration of trial treatment, throughout trial treatment and for the duration outlined in trial protocol as well as addition 14 days for women and 7 days for men after the last dose of trial treatment.
  • Severity Grading System (SGS) for CCHF - mild/moderate.
  • Less than or equal to 7 days from onset of CCHF symptoms
  • Willingness to participate in the full protocol
  • Requirement to be hospitalised for treatment-
Exclusion Criteria
  • Stage 4 severe chronic kidney disease or requiring dialysis (i.e., estimated glomerular filtration (eGFR) rate \<30 mL/min/1.73 m2)
  • Pregnant or breast feeding
  • Anticipated transfer to another hospital which is not a study site within 72 hours
  • Known Allergy to any study medication
  • Patients participating in another clinical trial of an investigational medicinal product (CTIMP) within the last 30 days.
  • Previous intolerance of Favipiravir or Ribavirin
  • Any participants deemed not suitable, based on investigators opinion.
  • Patients taking the drugs listed below within 30 days or 5 times the half-life (whichever is longer) of enrolment
    • Pyrazinamide: Pyrazinamide administration with favipiravir examined possible renal urate transporter interactions. Pyrazinamide increased blood uric acid levels 2 to 9 mg/dL over baseline. The addition of favipiravir increased blood uric acid levels 4 to 11 mg/dL over baseline, indicating a moderate additive effect.
    • Repaglinide: Favipiravir administration with repaglinide, an anti-diabetic agent that is extensively metabolized by CYP2C8 and CYP3A4, increased repaglinide plasma AUC 30 to 50% due to inhibition of CYP2C8.
    • Theophylline: Theophylline administration with favipiravir increases plasma Cmax and AUC of favipiravir through xanthine oxidase (XO) interaction. The primary metabolite of theophylline is known to be metabolized by XO which is partially involved in metabolism of favipiravir.
    • Famciclovir, Sulindac: Famciclovir and Sulindac are converted to active metabolite by Aldehyde Oxidase (AO). Favipiravir inhibits AO and decrease the concentration of active metabolite of Famciclovir and Sulindac.
    • Paracetamol: Coadministration of paracetamol (650 mg once daily) and favipiravir (1200 mg twice daily or 800 mg twice daily) increased paracetamol Cmax and AUC by 3% and 16% (1200 mg doses) and by 8% and 14% (800 mg doses). In the UMIT-2 trial after screening and randomisation the daily dose of paracetamol in adults should be no more than 3000 mg/day (rather than 4000 mg/day) -
