A Phase III, Randomized, Double-Blind, Placebo Controlled Trial to Evaluate the Efficacy and Safety of Nitazoxanide in the Treatment of Colds Due to Enterovirus/Rhinovirus Infection

Trial to evaluate efficacy and safety of nitazoxanide in the treatment of colds due to
Enterovirus/Rhinovirus infection

Multicenter, randomized, double-blind, placebo-controlled trial to evaluate efficacy and
safety of nitazoxanide in the treatment of colds due to Enterovirus/Rhinovirus infection

Inclusion Criteria:

1. Male and female subjects at least 12 years of age

2. Presence of clinical signs and/or symptoms consistent with an acute illness compatible
with EV/RV infection (each of the following is required):

1. Presence of moderate or severe rhinorrhea defined as "attempting to relieve nasal
symptoms by blowing, wiping, or sniffling at least twice per hour for any one
hour within 12 hours preceding study entry," AND

2. Presence of cough, sore throat or nasal obstruction.

3. Negative rapid influenza diagnostic test (required only if the subject has an oral
temperature >100°F in the clinic or if the latest CDC weekly influenza report shows
influenza prevalence "Regional" or higher for the institution's state). A result from
a rapid influenza diagnostic test performed on the same day that informed consent is
obtained will be sufficient to meet this criterion if documentation of test results is
available as part of medical history.

4. Onset of illness no more than 40 hours before enrollment in the trial. Onset of
illness is defined as the first time at which the subject experienced rhinorrhea,
cough, sore throat or nasal obstruction.

5. Willing and able to provide written informed consent (including assent by legal
guardian if under 18 years of age) and comply with the requirements of the protocol,
including completion of the subject diary

Exclusion Criteria:

1. Persons requiring or anticipated to require in-hospital care

2. Cystic fibrosis

3. Cardiac arrhythmia

4. Immunologic disorders or receiving immunosuppressive therapy (e.g., for organ or bone
marrow transplants, immunomodulatory therapies for certain autoimmune diseases)

5. Untreated HIV infection or treated HIV infection with a CD4 count below 350 cells/mm3
in the last 6 months

6. Persons with sickle cell anemia or other hemoglobinopathies

7. Poorly controlled insulin-dependent diabetes mellitus (HbA1C >8.0%)

8. Concurrent infection at the screening examination that requires systemic antimicrobial
therapy

9. Females of childbearing potential who are either pregnant or sexually active without
the use of birth control. Female subjects of child-bearing potential that are sexually
active must have a negative baseline pregnancy test and must agree to continue an
acceptable method of birth control for the duration of the study and for 1 month
post-treatment. A double barrier method, oral birth control pills administered for at
least 2 monthly cycles prior to study drug administration, an IUD, or
medroxyprogesterone acetate administered intramuscularly for a minimum of one month
prior to study drug administration are acceptable methods of birth control for
inclusion into the study. Female subjects are considered of childbearing potential
unless they are postmenopausal (absence of menstrual bleeding for 1 year - or 6 months
if laboratory confirmation of hormonal status), or have had a hysterectomy, bilateral
tubular ligation or bilateral oophorectomy.

10. Females who are breastfeeding

11. Receipt of any dose of NTZ within 30 days prior to screening

12. Prior treatment with any investigational drug therapy within 30 days prior to
screening

13. Subjects with active respiratory allergies or subjects expected to require
anti-allergy medications during the study period for respiratory allergies

14. Known sensitivity to NTZ or any of the excipients comprising the NTZ tablets

15. Subjects unable to take oral medications

16. Subjects who, in the judgment of the Investigator, will be unlikely to comply with the
requirements of this protocol including completion of the subject diary
