Study Arms:
- Placebo (Type: PLACEBO_COMPARATOR): Each Strata of the study will have a placebo control. In strata A, the chance of getting active drug is 4 out of 5, in Strata B the chance of getting active drug is 3 ot of 4, and in Strata C, the chance of getting active Drug is 4 out of 5. In the event that a patient is allocated to receive placebo, the treatment may be stopped if the patient's condition fails to improve or worsens during the placebo infusion.
- Strata 1 CXL-1020 (Type: EXPERIMENTAL): Patients assigned to CXL-1020 in strata one will have their dose increased from the initial dose 2 times during the study period. The treatment may be stopped if the patient's condition fails to improve or worsens during the infusion.
- Strata 2 CXL-1020 (Type: EXPERIMENTAL): In strata 2, patients who are assigned to active treatment will receive one of up to 3 possible fixed dose levels of CXL-1020 for a period of 6 hours. The treatment may be stopped if the patient's condition fails to improve or worsens during the infusion.
- Strata 3 CXL-1020 (Type: EXPERIMENTAL): In strata 3, patients assigned to receive CXL-1020 will receive a fixed dose of CXL-1020 for 6 hours, and then the dose may be increased or decreased, based on the investigators assessment of the patient. The treatment may be stopped if the patient's condition fails to improve or worsens during the infusion.
