Phase 2 Study of CAL02 plus Standard of Care in Severe Community-Acquired Bacterial Pneumonia (SCABP

  • Status
    Accepting Candidates
  • Age
    18 Years - N/A
  • Sexes
  • Healthy Volunteers


This is a placebo-controlled study to evaluate the addition of CAL02 to standard of care in treating hospitalized subjects diagnosed with severe community acquired bacterial pneumonia (SCABP) requiring critical care measures


Subjects diagnosed with SCABP and requiring critical care measures, will receive either 2 intravenous infusions of CAL02 (13.7 to 24 mg/kg bracketed dose by weight), administered 24-26 hours apart or 2 intravenous infusions of placebo. Additionally, all subjects will receive standard of care (SOC) therapy for SCABP, according to scientific guidelines. Critical care measures provide intensive and specialized medical and nursing care, a capacity for continuous monitoring 24 hours/day, and multiple modalities of physiologic organ support to sustain life in seriously/critically ill patients.

Participate in a study

Here are some general steps to consider when participating in a research study:

  1. Step

    Contact the research team

    Call or email the research team listed within the specific clinical trial or study to let them know that you're interested. A member of the research team, such as the researcher or study coordinator, will be available to tell you more about the study and to answer any questions or concerns you may have.

    Primary contact

  2. Step

    Get screened to confirm eligibility

    You may be asked to take part in prescreening to make sure you are eligible for a study. The prescreening process ensures it is safe for you to participate. During the prescreening process, you will be asked some questions and you may also be asked to schedule tests or procedures to confirm your eligibility.

  3. Step

    Provide your consent to participate

    If you are eligible and want to join the clinical trial or study, a member of the research team will ask for your consent to participate. To give consent, you will be asked to read and sign a consent form for the study. This consent form explains the study's purpose, procedures, risks, benefits and provides other important information, such as the study team's contact information.

  4. Step


    If you decide to participate in a clinical trial or study, the research team will keep you informed of the study requirements and what you will need to do to throughout the study. For some trials or studies, your health care provider may work with the research team to ensure there are no conflicts with other medications or treatments.
