A Single Dose Study of Debio 1450 in Healthy Subjects

The sponsor is trying to develop a medicine for infections that are not cured by regular antibiotics. They have an experimental drug called Debio 1450 that may work. They need about 48 healthy adults to volunteer for this study.

This study looks at what the body does to the drug. It measures how the amount of drug in blood and urine changes over time.

From the screening visit through the follow-up visit may be up to 40 days. Volunteers go to the clinic in Baltimore for a screening visit. The study doctor chooses qualified volunteers to participate or serve as alternates. Alternates might not actually complete the study procedures.

The study doctor divides participants into groups of eight. Six receive Debio 1450 and 2 receive Placebo. The drug each participant receives is decided by chance - like flipping a coin.

Eligible volunteers check into the clinic for testing and those chosen to participate remain for a 5-day/ 4-night stay. The clinic serves standard meals, except when fasting is required. Participants must stay at the clinic for the length of the study.

This study is a "dose escalation" study. That means that if no safety concerns come up a new group starts. Each new group of eight participants receives more capsules.

The study product is contained in capsules. Each capsule contains either placebo or 40 mg Debio 1450. After fasting overnight, the first two participants in the group receive their capsules. One gets Debio 1450 and one gets Placebo. If these participants tolerate side effects for 24 hours, the remaining six participants receive their assigned capsules.

The plan is to increase the dose for the next group. The study doctor reviews the measurements collected from each group after three days. He may decide to repeat, increase, or lower the dose or even stop the study. The most any participant receives is 800 mg in 20 capsules.

Treatment and study plan

Debio 1450

Drug

Single sentinel dosing of 40 mg per unit capsules is planned to escalate from 80 mg to 160, 320, 480, 640 and 800 mg, per respective dosing group. Doses may be modified based on review of available safety and pharmacokinetic (PK) data.

Placebo

Drug

Matching single sentinel dosing of placebo capsules is planned to escalate from 2 capsules to 4, 8, 12, 16 and 20 capsules, per respective dosing group. The number of capsules will match those delivering Debio 1450 for the group, as those doses may be modified based on review of available safety and pharmacokinetic (PK) data.

Primary outcomes

  1. Number of participants with at least one treatment emergent adverse event (TEAE)

    Time frame: within 10 days post-dose

  2. Maximum observed plasma concentration (Cmax) of Debio 1450

    Time frame: within 60 hours post-dose

  3. Time of maximum observed plasma concentration (tmax) of Debio 1450
