• Must have been on an approved H1 antihistamine for CIU for at least 3 consecutive days immediately prior to the Day -14 screening visit and must document current use on the day of initial screening.

• Presence of itch and hives for ≥ 8 consecutive weeks at any time prior to enrollment despite current use of H1 antihistamine treatment.

• In-clinic UAS ≥ 4 on at least 1 of the screening visit days (Day -14, Day -7, or Day 1).

• UAS7 (range 0-42) ≥ 16 and itch component of UAS7 (range 0-21) ≥ 8 during 7 days prior to randomization.

4. Willing and able to complete a daily symptom diary for the duration of the study and must not have any missing diary entries in the 7 days prior to randomization.

5. Females of childbearing potential must be willing to use acceptable contraceptive methods throughout the study and for 6 months thereafter.

6. Females of non-childbearing potential must have undergone sterilization procedures, at least 6 months prior to the first dose or be postmenopausal with amenorrhea for at least 1 year prior to the first dose and follicle stimulating hormone serum levels consistent with postmenopausal status.

Exclusion Criteria:

1. Participation in a clinical trial involving the administration of an investigational drug or marketed drug within 30 days prior to initial dosing (90 days for biologics).

2. Clearly defined underlying etiology for chronic urticarias other than CIU.

3. Evidence of parasitic infection.

4. Atopic dermatitis, bullous pemphigoid, dermatitis herpetiformis, senile pruritus, or any other skin disease associated with itch.

5. Previous treatment with omalizumab within a year prior to screening.

6. Routine doses of the following medications within 10 days prior to screening: Systemic or cutaneous (topical) corticosteroids (prescription or over the counter), hydroxychloroquine, methotrexate, cyclosporine, or cyclophosphamide or investigational agents such as benralizumab or dupilumab etc.

7. IVIG ( Intravenous immune globulin) or plasmapheresis within 90 days prior to screening.

8. Regular (daily/every other day) doxepin (oral) use within 14 days prior to screening.

9. Any H2 antihistamine use within 7 days prior to screening.

10. Any LTRA (Leukotriene receptor antagonists such as montelukast or zafirlukast) within 10 to 14 days prior to screening.

11. Patients with current malignancy, history of malignancy, or currently under work-up for suspected malignancy except non-melanoma skin cancer that has been treated or excised and is considered resolved.

12. Hypersensitivity to omalizumab or any component of the formulation.

13. History of anaphylactic shock.

14. Presence of clinically significant cardiovascular, neurological, psychiatric, metabolic, or other pathological conditions that could interfere with the interpretation of the study results and/or compromise the safety of the patients.

15. Medical examination or laboratory findings that suggest the possibility of decompensation of co-existing conditions for the duration of the study.

16. Evidence of current drug or alcohol abuse.

17. Positive test for hepatitis B, hepatitis C, or HIV.

18. Females with positive pregnancy tests at screening or any other visit.

19. Females who are breastfeeding or lactating.

20. History of any clinically significant disease or condition that, in the opinion of the Principal Investigator (PI)/designee, would render them unsuitable for inclusion in the study.
