Please assess the completion status of the following clinical trial:

Trial Title: Nitric Oxide in Cardiopulmonary Bypass for Renal Protection in Cardiac Surgery

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: PREVENTION
- Time Perspective: None
- Masking: TRIPLE
- Phase: PHASE1/PHASE2
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~Age above 18 years; planned primary cardiac intervention with cardiopulmonary bypass including coronary artery bypass grafting, valve surgery, and surgical reconstructions of the left ventricle.~Exclusion Criteria:~Preoperative anemia; the intake of nephrotoxic drugs or the use of X-ray contrast within 72 h before surgery; active phase of endocarditis; emergency surgery; chronic kidney disease; hematologic diseases accompanied by hemolysis; complications of the surgery and the early postoperative period.

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Nitric Oxide (Type: EXPERIMENTAL): Patients of this group receive treatment with exogenous gaseous nitric oxide supplied directly to the oxygenator in the cardiopulmonary bypass circuit during cardiac surgery.
- Standard CPB (Type: PLACEBO_COMPARATOR): Patients of this group receive sham-treatment without supplying nitric oxide to the cardiopulmonary bypass circuit (Standard CPB) during cardiac surgery. Considering dilution of nitric oxide at a high ratio of 1 to 25,000 in the gas mixture of the cardiopulmonary bypass circuit (CPB), no addition of any inert gas to the CPB circuit is required in sham-treatment group.

Based on this trial design, predict the completion outcome and termination type (if applicable).
