Study summary

This study will examine the safety of an experimental medication called Poly-ICLC, developed for preventing or reducing the severity of infections from influenza and other viruses acquired through the nose, mouth and lungs. The study is divided into two parts, in which Poly-ICLC is tested at different dose levels.

Healthy people between 18 and 70 years of age who have no chronic medical problems may be eligible for this study. Participants undergo the following procedures:

Part I

  • Up to 7 days before Poly-ICLC administration: Medical history, physical examination and blood tests.
  • Day 1: Nasal wash and Poly-ICLC administration. A small amount of salt water is placed into the front of the nose and then suctioned out. Poly-ICLC is then squirted into each nostril, one after the other, at a dose of 0.25, 0.5 or 1 mg. A small number of subjects are given a placebo (a solution with no active ingredient.) Subjects are observed in the clinic for 30 minutes after treatment.
  • Day 2: Subjects receive a second nasal wash and repeat blood tests. They keep a diary card for 1 week, recording any drug side effects.
  • Day 5: Subjects have repeat blood tests and a review of their diary card. The keep a diary card for another 3 weeks.
  • Day 12: Subjects are contacted by phone to review their diary card.
  • Day 28: Subjects are contacted by phone to review their diary card.

Part II

  • Up to 7 days before Poly-ICLC administration: Medical history, physical examination and blood tests.
  • Day 1: Nasal wash and Poly-ICLC administration. Same as above for Part I participants.
  • Day 3: Subjects receive a second dose of medication and are observed again for 30 minutes.
  • Day 4: Subjects receive a second nasal wash and repeat blood tests. They keep a diary card for 1 week, recording any drug side effects.
  • Day 7: Subjects have repeat blood tests and a review of their diary card. The keep a diary card for another 3 weeks.
  • Day 14: Subjects are contacted by phone to review their diary card.
  • Day 28: Subjects are contacted by phone to review their diary card.
Read the detailed description

Polyinosinic-Polycytidylic acid stabilized with polylysine and carboxymethylcellulose (Poly-ICLC), a stabilized double stranded RNA (dsRNA) therapeutic viral mimic activating innate and adaptive immunity, has been in extensive preclinical and investigational clinical therapeutic use as an intramuscular and intravenous compound, most recently in oncology applications. Only recently have the mechanisms of action been more fully elucidated, including induction of interferons, cytokines, and chemokines. Recognizing this, the infectious disease applications have been pursued in in vitro and animal models. Intranasal Poly-ICLC provides protection against mortality in animal models for multiple highly pathogenic viruses including influenza, severe acute respiratory distress syndrome (SARS), smallpox and Ebola. As its effects are not dependant on knowing the causative virus, an effective compound that could be protective against several unknown respiratory viruses has significant clinical appeal. While there is clinical safety data for intramuscular (IM) Poly-ICLC, no clinical studies of nasal application of Poly-ICLC have been done.

This study is a phase I safety and pharmacokinetic trial of nasally applied Poly-ICLC. Human volunteers will be administered increasing doses of nasal Poly-ICLC, with serial evaluation of safety, tolerability, as well as exploratory markers of immune activation.

Inclusion criteria

Healthy volunteers age greater than or equal to 18 years and less than or equal to 70 years.

For 2 months prior to study drug administration, and through the last day of follow-up (Day 28), subjects must agree to:

  • Not take any topical nasal medications (prescription or over the counter).
  • Not receive live attenuated influenza vaccine (Flumist) or any other live attenuated intranasal vaccine (licensed or research).
  • Not receive any other medications or vaccines.

Females of must agree to use one of the following methods of for 4 weeks prior to date of screening evaluation through 4 weeks after study drug administration:

  • Be surgically sterile.
  • Use oral contraceptives or other form of hormonal birth control including hormonal vaginal rings or transdermal patches.
  • Use an intra-uterine device (IUD).
  • Use (by ensuring her male partner(s) uses) barrier contraception (condom) with a spermicide.
  • Any other equivalent (as judged by the investigative team) methods of contraception.

Exclusion criteria

EXCLUSION CRITERIA:

A medical history that includes any of the following:

Any chronic medical problem that requires daily topical nasal medications.

Prior nasal or sinus surgery (including trans-nasal approaches of other organs such as pituitary).

Allergic rhinitis, chronic sinusitis, or any other nasal inflammatory disease that requires daily intranasal or oral medication.

Any chronic pulmonary conditions including (but not limited to) asthma, , and chronic bronchitis.

Subjects with known to interferons.

Any other medical history that in the opinion of the investigator significantly increases the risk associated with a Phase I drug (e.g. Patients with coronary heart disease, congestive heart failure, , neuropsychiatric disorders, seizure disorder, disease, hepatic decompensation, poorly controlled endocrine disorders (including poorly controlled diabetes, and actively hyper- or hypo-thyroid), hematological disorders (e.g. leukopenia, thrombocytopenia), ophthalmologic disorders (excluding errors or refractiveness) or other disorders for which symptoms of the condition could be similar to interferon-related toxicity or that might be exacerbated by interferon would be excluded. Patients with mild stable conditions, such as controlled hypertension, controlled diabetes, and osteoarthritis would be permitted to enroll.)

Any history of habitual intranasal cocaine or other intranasal recreational drug use at any time, or experimental intranasal concaine or other intranasal recreational drug use within the last 10 years. (e.g. a 50 year old who tried cocaine once at age 20 is acceptable for enrollment).

Women who are breast-feeding.

Positive urine or serum pregnancy test.

Participation in any research protocol that requires more than 100cc of blood to be given in any 6-week period of time.

Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 5, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
