Neisseria gonorrhoeae Infections

Demonstrate the non-inferiority of 2g IV or IM temocillin treatment compared to the reference treatment with 1g IM ceftriaxone (Standard of Care (SOC)) for Neisseria gonorrhoeae infections at D21 (negative PCR in urine/vagina, throat and/or anus).

Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Efficacy, Safety, Therapy

Demonstrate the non-inferiority of 2g IV or IM temocillin treatment compared to the reference treatment with 1g IM ceftriaxone (Standard of Care (SOC)) for Neisseria gonorrhoeae infections at D21 (negative PCR in urine/vagina, throat and/or anus).

Secondary objectives 6

  1. To compare each experimental treatment to the SOC in terms of: - Efficacy of treatments for Ng infections at D21, according to the infected site (negative PCR in urine/vagina, throat or anus).
  2. - Safety
  3. - Patient satisfaction/perception.
  4. - Impact of the different antimicrobial therapies on ESBL-E rectal carriage rate at D1, D21 and M3
  5. - Impact of the different antimicrobial therapies on throat/anal and urine/vagina microbiota at D1, D21 and M3
  6. - Population of Ng selected under treatment: MIC determination to ceftriaxone and temocillin, genotype, clonality and resistance determinants (sequence type (ST), resistance genes).

#TitleAllocationBlindingRoles blindedArms
1 Phase III
confirmatory multicenter, randomized, controlled, open-label non-inferiority trial with three parallel arms
Randomised Controlled None Arm1 - ceftriaxone (SOC): patients will receive a single 1 g dose of IM ceftriaxone (SOC) after reconstitution with 4 mL of lidocaine at 10 mg/mL to prevent pain at the injection site.
Arm2 - IM temocillin: patients will receive a single 2 g dose of IM temocillin after reconstitution with 4 mL of lidocaine at 10 mg/mL to prevent pain at the injection site. A single 1 g dose of temocillin has been used for the treatment of N. gonorrhoeae infection (Reimer et al., 1985). We chose to use a single 2 g dose because penicillin MICs are increasing. For bacterial STIs, treatment is currently administered via the intramuscular route, which is the fastest and most practical method of antibiotic administration for outpatients.
Arm3 - IV temocillin: patients will receive a single 2 g dose of IV temocillin diluted in 20 mL of water for injection. In this trial, we chose to test the IV route, as the classical intramuscular (IM) injection is often described as painful. We hypothesize that the IV route may be more comfortable for patients. Moreover, after administration of a 2 g IV bolus, the peak plasma concentration reaches approximately 220–250 mg/L, and temocillin concentrations remain detectable after 12 hours (the dosing interval) at around 15 mg/L. We hypothesize that this high plasma concentration could improve treatment of pharyngeal infection.

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Proportion of participants with therapeutic success at D21. Therapeutic success is defined by a negative PCR for Ng at all three sites (urine/vagina, throat and anus) at D21 of treatment.

Secondary endpoints 6

  1. - Proportion of participants with therapeutic success at D21 according to each infected site urine/vagina, throat or anus). Therapeutic success is defined by a negative PCR for the infection site at day 21 of treatment.
  2. - Incidence of clinical and biological adverse effects (AEs), grade 3 or 4 AEs, all-grade AEs, treatment-related adverse events (all grades), study discontinuations due to AEs, and serious adverse events at M3.
  3. - Satisfaction/perception evaluated by the patient at baseline (D1, after injection) and D21 (5 questions asked during consultation)
  4. - Proportion of ESBL-E rectal colonization at baseline (D1), D21, and M3
  5. - Composition of the throat/anal and urine/vagina microbiota at D1, D21 and M3
  6. - Ng populations, clonality, and analysis of resistance determinants (MIC, ST, resistance genes) at day 1 and D21.
