Trial Summary

What is the purpose of this trial?

Sepsis occurs when a serious infection - most commonly infection of the lungs, urinary system, or blood - leads to acute organ failure. It is a common, expensive, and frequently lethal condition. A growing body of evidence suggests that early recognition and treatment of sepsis can improve survival. Unfortunately, many patients with sepsis do not receive key therapies until physicians working in Emergency Departments have assessed them - often introducing marked delays. It is estimated that one-half of patients with sepsis are treated and transported to hospital by paramedics. This allows paramedics a unique opportunity to provide early treatment at the initial point of patient contact, thereby decreasing the time to treatment for these critically ill patients. This randomized controlled trial will evaluate whether prompt recognition followed by early antibiotics and/or intravenous fluids delivered by paramedics in the field leads to improved survival, compared to usual care, for patients who are transported to the hospital with sepsis.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but if you are taking anticoagulants (blood thinners), you cannot participate.

What data supports the effectiveness of the drug ceftriaxone (Rocephin) in treating sepsis?

Research shows that ceftriaxone (Rocephin) is effective in treating various bacterial infections, including sepsis, with good results in most cases. In a study, 90% of cirrhotic patients with bacterial infections responded well to ceftriaxone, and another study found that a 2 g daily dose reduced treatment failure in ICU patients. ^{1 2 3 4 5}

Is ceftriaxone generally safe for humans?

Ceftriaxone, used in various infections, is generally well-tolerated, but it can cause neutropenia (a low level of a type of white blood cell) and may have risks when used with intravenous calcium. In patients with acute renal failure, its elimination is impaired, requiring dosage adjustments. ^{1 2 3 6 7}

How is the treatment for sepsis using Ceftriaxone and fluid management different from other treatments?

This treatment is unique because it combines the antibiotic Ceftriaxone with a specific approach to fluid management, using either conservative (restricted) or liberal (more generous) fluid therapy, which is still debated in the medical community. The focus on early paramedic intervention and the balance of fluid volumes makes it distinct from standard sepsis treatments that may not emphasize these aspects. ^{8 9 10 11 12}

Treatment Details

Interventions

• Ceftriaxone (Anti-bacterial agent)
• Conservative fluids (Drug)
• Liberal fluids (Drug)
• Placebo (Drug)

Trial Overview The PITSTOP trial is testing if early treatment for sepsis by paramedics improves survival rates. It compares two approaches: one group receives an antibiotic called Ceftriaxone and either liberal or conservative fluids before hospital arrival; the other gets a placebo instead of antibiotics.

Participant Groups

Group I: Comparison 2: Liberal fluids Experimental Treatment 1 Intervention

Paramedics will administer up to 2 litres of intravenous 0.9% saline solution to all participants in this arm regardless of blood pressure, reassessing for signs of volume overload after each 250ml.

Group II: Comparison 1: Prehospital Ceftriaxone Active Control 1 Intervention

1g of Ceftriaxone will be administered by immediate intramuscular (IM) injection. The drug is provided in a sterile and completely covered vial as a white, odourless powder

Group III: Comparison 2: Conservative fluids Active Control 1 Intervention

Paramedics will administer 0.9% saline solution to participants who have systolic blood pressure \<90mmHg, and will only continue the infusion until the systolic blood pressure is \>=100mmHg.

Group IV: Comparison 1: Placebo Placebo Group 1 Intervention

The placebo is provided in a sterile and completely covered vial.

Ceftriaxone is already approved in Canada for the following indications:

Approved in Canada as Rocephin for:

• Sepsis
• Bacterial infections
• Meningitis
• Gonorrhea
• Pelvic inflammatory disease
• Lower respiratory tract infections
• Skin and skin structure infections
• Urinary tract infections

Findings from Research

In a study involving 51 cirrhotic patients with 62 episodes of bacterial infection, intravenous ceftriaxone was administered once daily for 7-10 days, showing a good response rate in 90% of cases.

Ceftriaxone was effective in treating various types of infections, including pneumonia and spontaneous bacterial peritonitis, indicating its potential as a reliable treatment option for bacterial infections in cirrhotic patients.

In a study of 12 patients (5 with acute renal failure and 7 without), ceftriaxone clearance was found to be significantly impaired in those with renal issues, indicating that dosage adjustments are necessary based on kidney function.

The research showed that renal clearance of ceftriaxone is closely linked to creatinine clearance, and that non-renal clearance is also reduced, suggesting that patients with acute renal failure may not effectively eliminate the drug, necessitating careful monitoring and dosage modifications.

In a pilot study of 57 critically ill patients with sepsis, continuous infusion of ceftriaxone showed a trend towards better clinical outcomes compared to once-daily bolus dosing, particularly in patients who received treatment for 4 or more days.

Logistic regression analysis indicated that continuous infusion was associated with significantly improved clinical outcomes, especially in patients with lower APACHE II scores, suggesting that this method of administration may enhance the efficacy of ceftriaxone in severe cases of sepsis.

Starch solutions should be avoided in sepsis patients due to lack of benefit and potential harm, including kidney issues and increased mortality, as highlighted by recent large clinical trials.

Norepinephrine is recommended as the first-line vasopressor for sepsis treatment, while early antibiotic therapy is crucial, and etomidate should not be used in these patients.

The REFRESH trial is a multicenter, open-label study designed to compare the effects of standard care (a second 1000-ml fluid bolus) versus restricted fluid maintenance in patients with sepsis and hypotension, aiming to determine the optimal fluid resuscitation strategy.

This trial will not only measure the total fluid volume administered in the first 6 hours but also assess secondary outcomes like organ support days and 90-day mortality, while exploring biomarkers to understand the impact of fluid volume on inflammation and vascular health.
