2-DG-02 is a randomized, placebo-controlled, double-blind Phase 2 study to investigate the efficacy and safety of 2-Deoxy-D-Glucose as a pre-exposure prophylaxis using the rhinovirus challenge model in healthy study participants.
2-DG-02 is a randomized, placebo-controlled, double-blind Phase 2 study using the rhinovirus challenge model in healthy study participants aged 18 to 64 years. The primary objective is to confirm the efficacy of 2-DG compared to placebo for the prevention of rhinovirus-associated illness. Secondary objectives are * to evaluate the effect of 2-DG on the occurrence and course of rhinovirus infection * to evaluate the effect of 2-DG on the severity of symptoms of rhinovirus infection * to evaluate safety and tolerability of 2-DG administrated over 1 week in the presence of rhinovirus exposure * to evaluate pharmacokinetics of 2-DG 128 subjects, who have been pre-screened and found to be seronegative to rhinovirus type 39, are randomized 1:1 to either 2-DG (pre-exposure prophylaxis) or placebo the day prior to inoculation. Subjects receive 2-DG or placebo starting from the day prior to inoculation until 5 days post inoculation. Interim safety and efficacy reviews are performed by a Safety Monitoring Committee.

The difference in the rate of rhinovirus-associated illness between 2-DG and placebo
Difference in the rate of symptomatic illness and laboratory-confirmed infection
Time frame: baseline until day 22
Number of infected subjects
Difference in the number of subjects with laboratory-confirmed infections. A laboratory-confirmed infection is identified either by isolating rhinovirus on at least one day after the virus challenge using qPCR or by a 4-fold increase in neutralizing antibody titer to RV-39 from acute (day -1) to convalescent sera (day 22) using the neutralizing assay.
Time frame: baseline, days 2-22 after start of dosing
Difference in percent of infected subjects
Difference in percentage of subjects with laboratory-confirmed infections. A laboratory-confirmed infection is identified either by isolating rhinovirus on at least one day after the virus challenge using qPCR or by a 4-fold increase in neutralizing antibody titer to RV-39 from acute (day -1) to convalescent sera (day 22) using the neutralizing assay.
Time frame: baseline, days 2-22 after start of dosing
Difference in percent of days virus positive
Difference in the percentage of days with a positive virus load. A positive virus load is determined by isolating rhinovirus on at least one day following the virus challenge, either using qPCR or a TCID50 assay.
Time frame: days 2-6
Difference in peak nasal virus load
Virus load is confirmed by isolating rhinovirus on at least one day after the virus challenge, using either qPCR or a TCID50 assay.
Time frame: days 2-6
Difference in AUC nasal virus load

Difference in AUC log 10 nasal virus load. Virus load is confirmed by isolating rhinovirus on at least one day after the virus challenge, using either qPCR or a TCID50 assay.
Time frame: days 2-6
Difference in Total Jackson Symptom Score
The difference of total Jackson Symptom Score (4 point-liters scales from 0 to 3) where a lower score means a better outcome.
Time frame: days 2-6 after start of dosing
Duration of illness
In study participants with RAI duration of illness is the time to the first day of the two consecutive days with a total symptom score ≤ 1 that occurs after the subject has met the symptom criteria for a RAI. A lower duration means a better outcome.
Time frame: days 2-15 after start of dosing
Difference in percent of days Jackson Symptom Score positive
Percentage of days with positive Jackson Symptom Score ( score \>2), where a lower percentage means a better outcome compared to placebo.
Time frame: days 2-6 after start of dosing
Difference in Peak Jackson Symptom Score
The highest daily total of all patient-reported symptoms on the Jackson Cold Scale (4 point-liters scales from 0 to 3 where a lower score means a better outcome compared to placebo).
Time frame: days 2-6 after start of dosing
Difference in peak total WURSS-21
The highest daily total of all patient-reported symptoms on the WURSS-21 questionnaire (8-point Likert scales from 0 to 7) where a lower score means a better outcome compared to placebo.
Time frame: days 2-6 after start of dosing
Difference in AUC total WURSS-21
Difference in AUC total WURSS-21 based a score recorded through the WURSS-21 questionnaire (8-point Likert scales from 0 to 7) where lower score means a better outcome compared to placebo.
Time frame: days 2-6 after start of dosing
Occurrence of adverse events (AEs) and adverse drug-reactions (ADRs)
Number of AEs and ADRs assessed by type, frequency and severity graded as per Common Terminology Criteria for Adverse Events (CTCAE).
Time frame: from screening (day -56) until end of study (day 22± 2) after start of dosing
Biodistribution of multiple doses of 2-DG in plasma samples
Analysis of 2-DG concentrations in plasma samples measured by LCMS (μg/ml).
Time frame: baseline, days 6 and 22± 2 after start of dosing
Biodistribution of multiple doses of 2-DG in nasal wash samples
Analysis of 2-DG concentrations in nasal wash samples measured by LCMS (μg/ml).
Time frame: baseline, days 2-6 and day 22± 2 after start of dosing
