Brief Summary:

The main purposes of this study is to determine the following in participants with mild coronavirus disease 2019 (COVID-19):

  • Safety of a single dose of NT-I7
  • The immunological effects of NT-I7 on peripheral lymphocyte counts in COVID-19 patients.

Condition or disease Intervention/treatment Phase
COVID-19 Drug: Double-Blind NT-I7 Drug: Double-Blind Placebo Phase 1

Detailed Description:
This is a multisite, double-blind, randomized, placebo-controlled, dose-escalating, phase 1 trial of NT-I7 with standard of care (SOC) versus placebo with SOC to evaluate the safety and efficacy of NT-I7 in adults with mild coronavirus disease 2019 (COVID-19). After determination of eligibility and baseline assessment, a single dose of the study agent (NT-I7 or placebo) will be administered after 1:1 randomization, along with SOC. Research blood collection will occur at baseline, days 3, 7, 14, 30, 60 and 90 days after administration. Primary and secondary evaluations will include assessment of adverse events (AEs), absolute lymphocyte count (ALC), and trajectory of other lymphocytes subsets: CD4, CD8, natural killer (NK), B, and mucosal-associated-invariant T (MAIT) cells. The final study visit will be at day 90 after the study agent administration. The investigators hypothesize that NT-I7 is safe for administration and preserves lymphocyte homeostasis in patients with mild COVID-19.

  • efineptakin alfa
Placebo Comparator: Placebo
Placebo will be administered once by IM injection within 24 hours of baseline (day 0). The treatment course pursued in all enrolled participants will be a single dose. Dosing will be staggered with at least 72 hours between each study participant.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Evaluate the safety of a single dose of NT-I7 in a dose escalation fashion [ Time Frame: Up to approximately 30 days ]
    Assessment of the number and severity of AEs possibly, probably, or definitely related to study drug evaluated at 7 and 30 days.


Secondary Outcome Measures :
  1. Evaluate the immunological effects of NT-I7 cumulatively for all doses on peripheral lymphocyte counts in COVID-19 patients. [ Time Frame: Up to approximately 30 days ]
    Assessment of the trajectory of ALC, CD4, CD8, NK, B, and MAIT cells measured at days 7, 14 and 30 after administration of NT-I7 or placebo compared to baseline values.
