5. Study Description

Brief Summary
CMTX-101 is a bacterial biofilm disrupting monoclonal antibody being developed as an adjunct therapy with standard of care antibiotics. The goal of this clinical trial is to assess the safety and tolerability of CMTX-101 in healthy volunteers followed by a similar assessment in patients with suspected or confirmed community acquired bacterial pneumonia of moderate severity. The main questions the study aims to answer are: Are single ascending doses of a CMTX-101 intravenous (IV) infusion safe and tolerated What is the pharmacokinetic (PK) profile of single-ascending doses CMTX 101 Do single ascending doses of CMTX 101 induce development of anti-drug antibodies (ADA) and neutralizing antibodies (Nabs) Exploratory efficacy biomarkers will also be measured in the patient part of the study. Participants will be administered a single IV infusion of CMTX-101 over a 60-minute period; patients will receive the infusion after starting standard of care antibiotics.

Has hypotension, defined as a systolic blood pressure <90 mmHg; Has known evidence of bone marrow suppression defined as the following: Leukocytes <3000 cells/µL; Absolute neutrophil count <1500 cells/µL; Platelets <100,000/µL; or Hemoglobin <8 g/dL. Has known liver function test abnormalities defined as the following: Total bilirubin >1.5 x ULN; ALT and/or AST >3 x ULN; or ALP >2.5 x ULN. Has a known estimated glomerular filtration rate <30 mL/min; Has received >24 hours of IV antibiotic administration during the current hospitalization for CABP; Note: Patients who have received IV standard-of-care antibiotics for >24 hours but ≤36 hours during their hospitalization may be considered for enrollment on a case-by-case basis after Medical Monitor and/or Sponsor approval. Note: There is no restriction on the duration of outpatient antibiotics that the patient may have received prior to hospitalization; Is hemodynamically unstable, defined as a mean arterial pressure <60 mmHg despite adequate fluid resuscitation and/or requires vasopressor support; Has a confirmed or suspected pleural empyema (does not include sterile parapneumonic effusion); Has known or suspected meningitis, endocarditis, or osteomyelitis; Has a history of post-obstructive pneumonia; Has suspected or confirmed active primary lung cancer or another malignancy metastatic to the lungs; Has a noninfectious cause of pulmonary infiltrates (i.e., pulmonary embolism, chemical pneumonitis, congestive heart failure, lung cancer, or cystic fibrosis); Has a known or suspected pneumonia of viral etiology, confirmed by a rapid viral diagnostic panel; Note: If a viral respiratory panel has not been collected within the 24 hours prior to Screening, a viral respiratory panel will be administered at Screening to determine eligibility. At a minimum, the panel will evaluate for respiratory syncytial virus, influenza A, influenza B and SARS-CoV-2. Has known severe immunosuppression, including but not limited to receipt of corticosteroid therapy (i.e., ≥20 mg of prednisone/day or equivalent for >4 weeks) within the previous 8 weeks, solid organ or bone marrow transplantation within the previous 12 months, or is currently receiving cytotoxic chemotherapy; or Has a life expectancy of ≤3 months because of any disease or has a medical, psychiatric, occupational, or substance abuse problem that, in the opinion of the Investigator, will make it unlikely that the subject will comply with the Protocol.
