Brief Summary

OPT101-100-40 is a multicenter, randomized, placebo-controlled, multiple-ascending-dose, sequential-group, investigator- and participant-blinded, sponsor-unblinded, study of OPT101 vs placebo when administered for up to 4 days to patients admitted to the hospital for treatment of Community Acquired Pneumonia (CAP) with sepsis.

This study will be performed in patients with Community Acquired Pneumonia (CAP) with Sepsis, who are 18 years or older to evaluate the safety and tolerability of OPT101 in a population with elevated levels of pathologic CD40.

Conditions

Sepsis; Community Acquired Pneumonia (CAP)

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: TRIPLE

Study Groups

0.9% Sodium Chloride Injection USP

Placebo will be 50mL normal saline (Sodium Chloride), USP sterile solution provided in a 50mL pre-packaged Intravenous (IV) bag.

Group Type: PLACEBO_COMPARATOR

Placebo

Intervention Type: OTHER

0.9% Sodium Chloride Injection USP, Placebo. On the day of administration, a 50mL IV bag containing saline (0.9% Sodium Chloride Injection USP) which will serve as the placebo will be administered via intravenous (IV) infusion over 120 minutes.

OPT101

OPT101 (15-mer peptide) will be provided across 2 cohorts at 1.1 (cohort 1) and 2.8 mg/kg (cohort 2) doses . On the day of administration, the product will be diluted in saline to result in 50 mL for intravenous (IV) infusion over 120 minutes.

Group Type: EXPERIMENTAL

OPT101

Intervention Type: DRUG

OPT101, is a 15-mer peptide derived from the sequence of mouse CD40L and was designed to target CD40-mediated inflammation. On the day of administration, the product will be diluted in saline to result in 50 mL for intravenous (IV) infusion over 120 minutes.
