Efficacy of Temocillin Compared to Standard of Care in the Treatment of Neisseria Gonorrhoeae Infections (TEMtoGo)

Efficacy of Temocillin Compared to Standard of Care in the Treatment of Neisseria Gonorrhoeae Infections : A Multicenter Randomized Controlled Non-Inferiority Trial

Neisseria gonorrhoeae (Ng) infections are common and increasing in incidence. Treatment with a third generation cephalosporin, i.e ceftriaxone 1g, single dose, intramuscular (IM), is recommended as a first line treatment. Ceftriaxone is a broad-spectrum antibiotic with high impact on the intestinal microbiota associated with the acquisition of multidrug-resistant bacteria, particularly extended spectrum beta lactamase producing Enterobacteracerales (ESBL-E). Among populations at high risk for sexually transmitted infections (STI), the colonization rate of ESBL-E is particularly high, up to 30%, implying (i) a risk of transmission within the community and (ii) a risk of infections caused by multidrug-resistant organisms, which are difficult to treat. Temocillin, a narrow-spectrum antibiotic is known for its low ecological impact, appears to be a highly promising option. Ng strains currently circulating in France appear to be sensitive to it. Thus, temocillin could be as effective as ceftriaxone to treat Ng infections while avoiding the deleterious impact of broad-spectrum β-lactams on the acquisition of multidrug-resistant bacteria by patients

Подробное описание

Sexually transmitted infections (STIs) are a major global public health issue. Ng infections are highly prevalent, with 100,000 cases reported in Europe in 2023, over 50% in men who have sex with men (MSM). Globally, WHO (World Health Organization) estimated 82.4 million new cases in 2020 among individuals aged 15-49, with incidence rates of 19 per 1000 women and 23 per 1000 men.

In France, Ng infections have been rising since the 2000s, particularly in MSM, with positivity rates 5-6 times higher than in heterosexual men and 7 times higher than in heterosexual women. Infections are mostly asymptomatic (~95%), though urethritis, cervicitis, proctitis, arthritis, and disseminated infections can occur.

Ng rapidly develops antimicrobial resistance due to genetic plasticity. Multidrug-resistant strains have emerged globally, but in France nearly all strains remain ceftriaxone-sensitive, with only 0.2% resistant in 2022. Standard treatment is ceftriaxone 1 g IM, a critical antibiotic impacting microbiota, and the only effective current option. Vaccine development is ongoing: the Bexsero vaccine showed 22% efficacy in reducing infections, and Phase 1/2 trials of Ng-specific vaccines are underway. Vaccine hesitancy and heterogeneous coverage, even in high-risk populations such as HIV (Human Immunodeficiency Virus) positive MSM, may limit rapid impact.

Alternative therapies include antibiotic combinations and new agents such as zoliflodacin, though pharyngeal efficacy is lower and broad-spectrum use is limited due to resistance concerns. Repositioning antibiotics has been explored: gentamicin shows low microbiota impact but lower pharyngeal efficacy; fosfomycin is ineffective for Ng; carbapenems (ertapenem) are effective but reserved for multidrug-resistant cases; temocillin, a narrow-spectrum β-lactam, preserves microbiota and colonization resistance and may improve pharyngeal clearance when given IV (Intravenous) or IM. Patient-centered outcomes, including perceived care quality, speed, and pain, will be assessed using short satisfaction questionnaires.

The main objective of this study is to 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 day 21 (negative PCR (Polymerase Chain Reaction) in urine/vagina, throat and/or anus).

The primary endpoint is the proportion of participants with therapeutic success at day 21.

The participants will be adults' patients consulting in the inclusion centers, having positive PCR for Ng (urine/vagina, throat or anus). We will focus on asymptomatic patients.

This trial will then have 3 arms: - Arm 1, patients will receive a single 1 g dose of IM ceftriaxone (SOC). -Arm 2, patients will receive a single 2 g dose of IM temocillin - Arm 3, patients will receive a single 2 g dose of IV temocillin.

The total duration of the study is planned to be 27 months, Follow-up visits will be scheduled at Day 21 and Day 90.

Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. However, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient.

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.

Лекарство: Temocillin (NEGABAN®) 2 g intravenous with lidocaine (3ml)
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 a slow intravenous injection (over 3 to 4 minutes), 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.
