Criteria
Inclusion Criteria:

1. Subject has read and voluntarily signed the Informed Consent Form (ICF) after all
questions have been answered and prior to any study-mandated procedure.

2. Adult aged 66-85 years inclusive.

3. Documented medical history consistent with age-related sensorineural hearing loss
(documented audiogram at least 6 months prior to screening required).

4. A pure tone average of 26-70 dB at 500Hz, 1000Hz, 2000Hz, and 4000Hz at Screening in
the ear to be injected.

5. Ability to communicate well with the Investigator and is willing to comply with and
complete all the study procedures.

Exclusion Criteria:

1. Subject has previously participated in a FX-322 clinical trial.

2. Any subject with a flat audiogram between 500Hz and 8000Hz at Screening in the study
ear. The difference in the range of threshold values across frequencies is ≤15 dB for
the definition of a flat audiogram.

3. Clinically significant abnormalities on safety laboratory tests.

4. Perforation of tympanic membrane or other tympanic membrane disorders that would
interfere with the delivery and safety assessment of an intratympanic medication or
reasonably be suspected to affect tympanic membrane healing after injection in study
ear. This includes a current tympanostomy tube.

5. Any conductive hearing loss of greater than 15 dB at a single frequency or greater
than 10 dB at two or more contiguous octave frequencies in the study ear at the
Screening visit or on the prior audiogram (if the Investigator feels there is not a
true conductive hearing loss, the Medical Monitor should be consulted).

6. Active chronic middle ear disease or a history of major middle ear surgery, as an
adult, in the ear to be injected.

7. Subject has had an intratympanic injection in either ear within 3 months of the
screening visit.

8. History of clinically significant vestibular symptoms at the discretion of the
investigator. For example, BPPV may be considered acceptable whereas Meniere's would
not.

9. History of clinically significant systemic autoimmune disease (e.g. rheumatoid
arthritis, Sjogren's syndrome, multiple sclerosis, psoriasis).

10. Exposure to another investigational drug within 28 days prior to injection of study
drug.

11. Evidence of any active or chronic disease or condition that could interfere with, or
for which the treatment of might interfere with, the conduct of the study, or that
would pose an unacceptable risk to the subject in the opinion of the investigator
following a detailed medical history, physical examination, and vital signs (systolic
and diastolic blood pressure, pulse rate, body temperature).

12. Females of childbearing potential (those who are not surgically sterilized or
post-menopausal) may not participate in the study if any of the following conditions
exist:

- Pregnant or intend to become pregnant

- Nursing (lactating)

- Does not agree to use adequate birth control methods for the duration of the
study (adequate birth control methods are: hormonal- oral, implantable,
transdermal or injectable contraceptives; mechanical- spermicide in conjunction
with a barrier such as a condom or diaphragm, IUD, or surgical sterilization of a
partner.

NOTE: all female subjects of childbearing potential must consent to a urine pregnancy
test as described in the Schedule of Assessments

13. Any known factor, condition, or disease that, in the view of the Investigator, might
interfere with treatment compliance, study conduct or interpretation of the results
(e.g. previous high-dose aminoglycoside treatment).
