Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a Phase 1, first in human (FIH) study utilizing a 3+3 design to assess the safety and pharmacology of single ascending doses (SAD) of GIGA-2050 in patients hospitalized with confirmed COVID-19. Participants will receive a single intravenous (IV) infusion dose of GIGA-2050 and followed for safety, pharmacology and efficacy assessments during hospitalization, after discharge (if applicable), and through study discontinuation or end of study visit (Day 56).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

  • Requires oxygen supplementation with FIO2 approximately 30% or greater administered by nasal cannula, mask, or NIV.
  • Participants can be on other medication on-label to treat COVID-19 respiratory disease that the Investigator deems clinically relevant in combination with the study drug, including corticosteroids. Passage of 24 hours after administration of the EUA drug will be required prior to dosing GIGA-2050.

  • Pre-existing heart failure or unstable angina or myocardial infarction in the last month prior to screening.
  • Pre-existing chronic respiratory condition(s).
  • Evidence of acute kidney injury, increase of serum creatinine of ≥1.5 x baseline, or urine output of <0.5mL/kg/hr sustained for at least 6 hours once volume repleted.
  • Aspartate aminotransferase (AST) ≥2.5 x ULN, alanine aminotransferase (ALT) ≥2.5 x ULN, and/or total bilirubin >1.5 x ULN, or severe hepatic impairment.
  • Known systemic hypersensitivity to recombinant antibody therapies.
  • Female participant who is pregnant.
  • Participant is expected to transfer to a non-investigative facility from the investigation site and cannot be monitored for compliance with protocol-required safety monitoring procedures.
  • Participants who are currently participating or have participated in another clinical trial within 30 days prior to screening.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of treatment-emergent adverse events (TEAEs)
Time Frame: Day 1 up to Day 56
Frequency of TEAEs graded by the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0
Day 1 up to Day 56
Incidence of dose limiting toxicities (DLTs)
Time Frame: Day 1 up to Day 3
Frequency of DLTs at each dose level
Day 1 up to Day 3
Change from baseline of vital signs, physical examination, and clinical laboratory assessments
Time Frame: Day 1 up to Day 56
Numeric summaries of all observed findings and changes for vital signs, laboratory assessments, physical examinations, and ECG
Day 1 up to Day 56
Incidence of infusion-related reactions (IRR) and hypersensitivity reactions
Time Frame: Day 1 through Day 2
Frequency of IRR and hypersensitivity reactions
Day 1 through Day 2

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure

Pharmacological evaluation of single doses of GIGA-2050
Time Frame: Day 1 up to Day 28
Serum titers of antibodies directed against SARS CoV-2 will be measured for the pharmacological profile of single doses of GIGA-2050
