Please assess the completion status of the following clinical trial:

Trial Title: Studies of Acute Lung Injury (ALI) and Acute Respiratory Distress Syndrome

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: PHASE1
- Number of Arms: 4.0

Eligibility Criteria:
Inclusion Criteria:~1. Informed written consent from the patient, or a written consent from a relative together with a the doctor responsible for the treatment of the patient~2. Aged 18 years or above.~3. Severe sepsis diagnosed less than 72 h prior to randomization.~4. Septic shock defined as a syndrome characterized by severe sepsis in association with either:~   * a MAP \<70 mm Hg for at least 30 consecutive minutes despite fluid resuscitation or,~  * a requirement for vasopressor support with a constant dose rate of either epinephrine \>0,05 mcg/kg/min and/or norepinephrine \>0.05 mcg/kg/min and/or dopamine \>5 mcg/kg/min and/or phenylephrine \>0.5 mcg/kg/min for at least 30 consecutive minutes to maintain a MAP \>90 mm Hg~5. Cardiac index (CI) must be \>3.5 l/min/m2, pulmonary artery occlusion pressure (PAOP) must be between 8 and 18 mm Hg, and in the opinion of the investigator the patient must be adequately fluid resuscitated~6. A 4 French Pulsiocath thermodilution catheter (Pulsion Medical Systems, München, Germany) in place in one of the femoral arteries and a 7 French thermistor-tipped balloon floatation catheter (Swan Ganz) in the pulmonary artery for determination of hemodynamics, including extravascular lung water index (EVLWI).~7. A dedicated intravenous line for infusion of MB~8. A respirator with a device for delivery of gaseous NO to the inspiration gas and equipped with analysis tools for lung mechanics~9. The patients will be treated in intensive care units with the possibility to provide full life support for the whole duration of the study~10. In female patients a negative pregnancy test will be requires before inclusion unless the patient is either in the post-partum period or known to have undergone prior tubal ligation or hysterectomy, or be postmenopausal~Exclusion Criteria:~* 1) Patients who have received vasopressor infusion therapy as described in the definition of septic shock either intermittently or continuously for a period of more than 24 h prior to randomization 2) The use of any vasoactive drug infusion other than epinephrine, norepinephrine, dopamine, phenylephrine and dobutamine, at the time of study entry 3) Patients in whom either vasodilators or dobutamine are contraindicated 4) Patients who cannot have their MAP managed safely within the range of 70-90 mm Hg (e.g. patients with raised intracranial pressure) 5) Shock due to any cause other than severe sepsis (e.g. drug reaction or drug overdose, adrenal insufficiency, pulmonary embolus, burn injury etc.) 6) Patients that are immunocompromised due to any of the following:~* known corticosteroid therapy either greater than or equal to a total daily dose equivalent to 1 mg/kg or greater than 70 mg/day of oral prednisolone for at least 7 consecutive days within one month prior to study entry,~* clinically suspected or known to have Acquired Immunodeficiency Syndrome (AIDS),~* granulocyte count less than 1000/mm3 due to a cause other than severe sepsis (e.g. metastatic or hematological malignancies or chemotherapy),~* immunosuppressant therapy (e.g. due to an organ or bone marrow transplant), 7) Underlying disease, exclusive of septic shock, which is expected to cause death within 1 month from study entry 8) Within 30 days prior to this study, the patient should not have been included in any other randomized therapeutic study of an agent not licensed, or administration of any other investigational agent for the treatment of sepsis and/or septic shock. Patients must not participate in such studies for at least 30 days after enrolment into this study.~  9) Pregnant women, pregnancy test required of any fertile women.
