A Phase IV Open-Label Pharmacokinetic Study of Minocycline for Injection Following a Single Infusion in Critically-Ill Adults (ACUMIN)

This is a Phase IV, multi-center open-label pharmacokinetic trial studying the
pharmacokinetics and pharmacodynamics of a single dose of Minocin IV. Up to 67 subjects will
be enrolled to obtain 50 evaluable, ICU patients who are already receiving antimicrobial
therapy for a known or suspected Gram-negative infection. The entire study duration will be
approximately 16 months and each subject participation duration will be approximately 2 days.
The study will be conducted at approximately 13 clinical sites. Each subject will receive a
single 200 mg dose of Minocin IV infused over approximately 60 minutes. Each subject will
have 7 PK samples collected (1 pre-dose, 6 post-dose) at designated time points over a ~48
hour period following the start of the Minocin IV infusion. The primary objectives are: 1) To
characterize minocycline PK at the population level in critically-ill adults, with illness
known or suspected to be caused by infection with Gram-negative bacteria and 2) To assess
patient-level and clinical covariates associated with minocycline pharmacokinetic properties
in critically-ill adults, with illness known or suspected to be caused by infection with
Gram-negative bacteria.

patient-level and clinical covariates associated with minocycline pharmacokinetic properties
in critically-ill adults, with illness known or suspected to be caused by infection with
Gram-negative bacteria. Up to 67 subjects will be enrolled in order to obtain 50 PK evaluable
subjects in the study. To be considered PK evaluable, a subject must receive the full
infusion of study drug, and is required to have at least 3 PK samples collected in the first
12 hours post dose and at least 1 PK sample collected 24-48 hours post dose. Subjects who are
dosed with minocycline but do not meet this PK sampling requirement will still be included in
the population PK analysis, but an additional subject will be enrolled as a replacement to
meet the goal of having 50 PK evaluable subjects with intensive PK sampling.

Inclusion Criteria:

1. Male or female > / = 18 years of age.

2. Subject is in the ICU, or is being admitted to the ICU.

3. Known or suspected Gram-negative infection for which the subject is receiving systemic
antibiotics, and which was the reason for admission to the ICU, or reason for
persistent need for ICU care.

4. Expectation, in the judgment of the investigator, that the subject will remain
admitted in the hospital for at least 48 hours following enrollment and that all study
procedures will be completed.

5. Expectation that intravenous access will be sufficient for drug infusion and either
intravenous or arterial access will be sufficient to allow for all protocol required
blood sampling to occur.

6. The subject, or legally authorized representative (LAR), is able and willing to
provide signed informed consent.

Exclusion Criteria:

1. History of significant hypersensitivity or allergic reaction to tetracycline
antibiotics.

2. Receipt of oral or intravenous tetracycline class drugs within 7 days of enrollment
(e.g., minocycline, tetracycline, tigecycline, doxycycline).

3. Use of isotretinoin within 2 weeks of enrollment into the study.

4. Major surgery* within 48 hours prior to enrollment.

*Major surgery is defined as "the opening of either a body cavity or the mesenchymal
barrier, using general anesthesia".

5. Pregnant or breastfeeding women.

6. Patient is being treated for intracranial hypertension.

7. Any condition that, in the judgment of the investigator, precludes participation
because it could affect subject safety.*

*Subjects on, or who may be considered for Renal Replacement Therapy (RRT) during the
study period are not excluded from participating in the study.

8. Receipt of an investigational study product within 7 days prior to enrollment.
Investigator discretion should be used when longer acting agents have been used in the
previous 30 days.
