2. Male and female adults, 18 through 65 years of age, inclusive.
3. Current diagnosis of AjDA as defined in the Diagnostic and Statistical Manual of
Mental Disorders, 5th Edition.
4. Clinician-rated Hamilton Anxiety Scale (HAM-A) score =20 at Screening (Visit 1) and no
greater than 15% decrease at Baseline (Visit 2).

use of an effective method of birth control throughout the Study, and must also have a
negative urine pregnancy test result at both Screening (Visit 1) and Baseline (Visit
2), prior to investigational product (IP) administration. Effective methods of
contraception include: condoms with spermicide, diaphragm with spermicide, hormonal
contraceptive agents (oral, transdermal, or injectable), or implantable contraceptive
devices.
8. Males whose sexual partners are women of childbearing potential must commit to the
consistent and correct use of an effective method of birth control throughout the
study.
9. Negative COVID-19 test either in the presence of COVID-19 symptoms or after exposure

Exclusion Criteria:
1. Any history of schizophrenia or schizoaffective disorder.
2. Any other current Axis I disorder, including, but not limited to, major depressive
disorder, bipolar disorder, post-traumatic stress disorder, obsessive-compulsive
disorder, premenstrual dysphoric disorder, and generalized anxiety disorder, which is
in poor control and the primary focus of treatment.
3. A diagnosis of social anxiety disorder with a score >60 on the Liebowitz Social

behavior during the course of their participation in the study, or considered to be an
imminent danger to themselves or others.
6. Clinically significant nasal pathology or history of significant nasal trauma, nasal
surgery, anosmia, or nasal septum perforation that may have damaged the nasal
chemosensory epithelium.
7. An acute or chronic condition, including an infectious illness, uncontrolled seasonal
allergies at the time of the study, or significant nasal congestion that potentially
could affect drug delivery to the nasal chemosensory epithelium. The Investigator may
allow concomitant use of over-the-counter nasal decongenstants as needed, since there
is no apparent drug interaction between these and PH94B.
8. Concomitant use of any anxiolytics, such as benzodiazepines or buspirone, during the
Study and within 30 days of Baseline (Visit 2).
9. Concomitant use of any over-the-counter, prescription product, or herbal preparation
for treatment of the symptoms of anxiety during the Study and within 30 days before
Study entry. Selective serotonin reuptake inhibitors, serotonin-norepinephrine
reuptake inhibitors, or other approved antidepressants are permitted as long as the
dose has been stable for 30 days prior to Baseline (Visit 2).
10. Women who have a positive urine or serum pregnancy test at either Screening or
Baseline visit or are currently breast feeding.
11. Subjects with clinically significant abnormalities in hematology, blood chemistry,
urinalysis, electrocardiogram, or physical examination identified at the Screening
visit that in the clinical judgment of the Investigator, could place the subject at
undue risk, interfere with study participation, or confound the results of the study.
12. Subjects with a positive urine drug screen at either the Screening visit or Baseline
visit (not including tetrahydrocannabinol).
13. Any current clinically significant and/or uncontrolled medical condition, based on
medical history or as evidenced in screening assessments, such as SARS-Cov-2, HIV,
cancer, stroke, congestive heart failure, uncontrolled diabetes mellitus, or any other
medical condition or disease that, in the clinical judgment of the Investigator, could
place the subject at undue risk, interfere with Study participation, or confound the
results of the Study.

could place the subject at undue risk, interfere with study participation, or confound
the results of the study.
15. History of cancer or malignant tumor not in remission for at least 2 years. Basal cell
skin cancers are not exclusionary.
