E2025 for Healthy Volunteers

No Placebo GroupAll trial participants will receive the active study treatment (no placebo)

What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing the safety of E2025, a substance given through an IV, in healthy adults.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications, but it mentions restrictions on certain medications and treatments. It's best to discuss your specific medications with the trial team to see if they are allowed.

What safety data exists for E2025 in healthy volunteers?

The safety data for E2025 in healthy volunteers is not directly available, but general safety information from phase-I studies shows that adverse events like headaches, drowsiness, and weakness can occur even with placebo treatments. It's important to note that safety reporting in clinical trials often lacks detailed information, so potential participants should be aware of this limitation.12345

Are You a Good Fit for This Trial?

This trial is for non-smoking adults aged 18-55 who are not pregnant, breastfeeding, or able to become pregnant. Participants must have a body weight of at least 50 kg and a BMI between 18 and <30. They should not have any significant medical conditions, abnormal test results requiring treatment, drug/alcohol abuse history in the past two years, or be taking certain medications.

Inclusion Criteria

I weigh at least 50 kg and my BMI is between 18 and 30.

Exclusion Criteria

Participants who contravene the restrictions on concomitant medications, food, beverages, physical activities, and others as defined in the protocol
You have a history of severe allergic reactions to foreign proteins, which can cause symptoms beyond just nasal or eye-related issues like in allergic rhinitis.
I am not pregnant, breastfeeding, and if I can have children, I agree to use birth control.

What Are the Treatments Tested in This Trial?

Interventions

  • E2025
  • Placebo
Trial Overview The study tests E2025's safety when given as a single IV infusion to healthy people compared with a placebo (a substance with no active drug). It looks at how the body reacts to it (pharmacodynamics) and how it moves through and out of the body (pharmacokinetics).

Published Research Related to This Trial

A review of 192 randomized clinical trials revealed that safety information is often underreported, with only 46% specifying reasons for withdrawals due to toxicity and only 39% adequately reporting clinical adverse effects.
To enhance safety reporting, the study emphasizes the need for standardized scales for adverse effects, systematic data collection, and detailed reporting of severe reactions, suggesting that improved practices could lead to better safety insights in clinical trials.
Improving safety reporting from randomised trials.Ioannidis, JP., Lau, J.[2018]
In a comprehensive review of 54 phase-I studies involving 1015 healthy volunteers over 10 years, the overall incidence of adverse events was found to be 12.8%, with a higher rate for active drugs (13.7%) compared to placebo (7.9%).
Most adverse events were minor, with only 3% classified as severe, and no deaths or life-threatening events reported, highlighting that while adverse events are common in phase-I trials, they are typically not serious.
Adverse events in phase-I studies: a report in 1015 healthy volunteers.Sibille, M., Deigat, N., Janin, A., et al.[2019]
In a review of 109 clinical studies with 1228 healthy volunteers, 19% reported adverse events during placebo administration, highlighting that even without active treatment, participants can experience side effects.
Adverse events were more common with repeated dosing (28%) and among elderly participants (26%), with headaches, drowsiness, and asthenia being the most frequently reported issues, indicating that placebo effects can significantly influence safety evaluations.
