Patient description: A 54-year-old obese woman admitted to the emergency department with abdominal pain that started 4 days ago with nausea and vomiting. The epigastric pain radiates to the right upper quadrant, getting worse after eating fatty food. The patient experienced similar pain twice in the past year. Her past medical history is remarkable for hypercholesterolemia and 2 NVDs. She has 2 children, and she is menopausal. She does not smoke, drink alcohol, or use illicit drugs. She is mildly febrile. Her BP is 150/85, HR 115, RR 15, T 38.2, SpO2 98% on RA. She is an obese woman with no acute distress. On palpation, she experiences epigastric tenderness and tenderness in the right upper quadrant without rebound. Bowel sounds are normal. Laboratory analysis is remarkable for elevated ESR and leukocytosis with a left shift. The ultrasound revealed several gallstones, biliary sludge and CBD stones. The smallest stone is 14mm.

Clinical trial eligibility criteria: eligible ages (years): 18.0-80.0,  Bacterial Pneumonia Adult subjects of either gender (aged ≥18 years and ≤80 years old.) 2. Body weight between 50 kg and 100 kg. 3. Clinical diagnosis of acute (developed within ≤21 past days) community acquired bacterial pneumonia based on the presence of two relevant signs (fever, tachypnoea, leukocytosis, or hypoxemia) and radiographic findings of new pulmonary infiltrate/s. 4. Subjects with pneumonia of sufficient severity requiring ICU management and with at least one of the two following major of severity present for less than 18 hours: 1. Requiring invasive mechanical ventilation for respiratory failure due to pneumonia, or 2. Requiring treatment with vasopressors (i.e., dopamine >5 mcg/kg/min or any dose of epinephrine, norepinephrine, phenylephrine or vasopressin) for at least 2 hours to maintain or attempt to maintain systolic blood pressure (SBP) >90 mm Hg (or mean arterial pressure [MAP] >70 mm Hg) after adequate fluid resuscitation (i.e. for shock). NOTE: Patients that are for 18 hours or more under high flow nasal cannula (HFNC) at ≥50 liters per minute and FiO2 ≥0.6 or under non-mechanical ventilation (NMV) are not eligible for the study 5. Female subject of no childbearing potential i.e. non-fertile, pre-menarche, permanently sterile (i.e. underwent hysterectomy, bilateral salpingectomy or bilateral ovariectomy) or post-menopausal (history of no menses for at least 12 months without an alternative medical cause) or Woman of childbearing potential* with a negative serum or urine pregnancy test (sensitive to 25 IU human chorionic gonadotropin [hCG]) and agree to use an adequate method of contraception for three months after the last dose of the IMP according to her preferred and usual life style. Adequate methods of female contraception for this study are: sexual abstinence (refraining from heterosexual intercourse), hormonal contraception (both progesterone-only or combined oestrogen and progesterone; both with inhibition of ovulation or where inhibition of ovulation is not the primary mechanism of action), intra-uterine device, bilateral tubal occlusion, condom use by male sexual partner(s) or medically-assessed successfully vasectomized male sexual partner(s). *A woman of childbearing potential is a woman between menarche and post-menopause (history of no menses for at least 12 months without an alternative medical cause) unless she has undergone hysterectomy, bilateral salpingectomy or bilateral ovariectomy Male subject agreeing to use one of the following methods of birth control according to his preferred and usual life style for three months after the last dose of the IMP: sexual abstinence (refraining from heterosexual intercourse), use of condoms or medically-assessed successful vasectomy , or having a female sexual partner(s) who is using an adequate method of contraception as described above. 6. Signed informed consent provided by the participant, the relatives or the designated legal representative according to local guidelines  A patient will not be included in the study if he/she meets ANY of the following 1. Subjects with Hospital acquired (HAP)-, Health Care acquired (HCAP) or Ventilator associated-pneumonia (VAP). 2. Subjects with pneumonia exclusively of viral or fungal origin*. Subjects with bacterial pneumonia co-infected with viruses and/or other microorganisms may be entered into the study. *Due to the short time window (up to 18 hours) between fulfillment of severity (i.e. initiation of invasive mechanical ventilation or vasopressors administration, whichever comes first) and the start of the first dose of study treatment, patients with a pneumonia of suspected bacterial origin by any established standard diagnostic method routinely applied at the study site (e.g. urinary antigen test, rt-PCR) can be entered into the study (confirmation of bacterial origin must be obtained afterwards). 3. Subjects with known or suspected Pneumocystis jirovecii (formerly known as Pneumocystis carinii) pneumonia. 4. Subjects with an aspiration pneumonia. 5. Subjects with known active tuberculosis. 6. Subjects with a history of post-obstructive pneumonia. 7. Subjects with cystic fibrosis. 8. Subjects with any chronic lung disease requiring oxygen therapy at home. 9. Presence of infection in another organ location caused by same pathogen (e.g. pneumococcal meningitis in the context of pneumococcal pneumonia). 10. Subjects expected to have rapidly fatal disease within 72 hours after randomisation. 11. Inability to maintain a mean arterial pressure ≥50 mmHg prior to screening despite the presence of vasopressors and intravenous fluids. 12. Subjects not expected to survive for 3 months due to other pre-existing medical conditions such as end-stage neoplasm or other diseases. 13. Subjects with a history of malignancy in the 5 years prior to screening, except for successfully surgically treated non-melanoma skin malignancies. 14. Subjects with known primary immunodeficiency disorder or with HIV infection and acquired immune deficiency syndrome (AIDS) with CD4 count <200 cells/mm^3 or not receiving highly active antiretroviral therapy (HAART) for HIV. 15. Subjects receiving immunosuppressant therapy (including chronic treatment with anti-tumour necrosis factor alpha (TNFα ) or on chronic high doses of steroids (single administration of ≥2 mg/kg body weight or 20 mg/day of prednisone or equivalent for ≥2 weeks). 16. Chronic granulocytopenia, not thought to be due to sepsis, as evidenced by an absolute neutrophil count <500 per µL>21 days prior to onset of pneumonia symptoms. 17. Subjects who received stem cell therapy, or allogenic transplantation (organ or bone marrow transplant) within the past 6 months. 18. Subjects receiving treatment with a biological agent (e.g. antibodies, cells), immunotherapy or plasma exchange treatment within the last 8 weeks. 19. Subjects currently receiving, or having received another investigational medication within 90 days prior to start of the study (or 5 half-lives of the investigational compound, whichever is longer). 20. Known allergies or hypersensitivity to Penicillin or Streptomycin and/or any component of CryoStor® CS10. 21. Subjects with a known liver function impairment associated with liver cirrhosis (Child Pugh C) or known oesophageal varices. 22. Subjects hospitalised within the previous 15 days. 23. Conditions resulting in a New York Heart Association or Canadian Cardiovascular Society Class IV functional status. 24. End-stage neuromuscular disorders (e.g. motor neuron diseases, myasthenia gravis, etc.) or cerebral disorders that impair weaning. 25. Patients with quadriplegia (traumatic or otherwise)
