• Subject is able to adhere to the study visit schedule and other protocol requirements.
• Subject has at least two clinically measurable keloid lesions on the trunk and/or extremities, that failed prior minimally invasive treatments for keloids including topicals and intralesional steroid injections. However, at least one keloid should not have been treated with surgery, cryotherapy, radiation, or any other procedure that leads to a deformity that interferes with proper clinical assessments.
• At least 50% of the subjects: subject has documented diagnosis of concomitant type 2 (atopic/allergic) (e.g., active AD, asthma, chronic rhinosinusitis with nasal polyposis, food allergy confirmed by skin prick test or food allergen specific IgE, seasonal allergies, other confirmed allergies).
• Subject is judged to be in otherwise good overall health as judged by the investigator, based on medical history, physical examination, and laboratory testing. (NOTE: The definition of good health means a subject does not have uncontrolled significant co-morbid conditions).
• Females of childbearing potential (FCBP) must have a negative pregnancy test at Screening and Baseline. While on investigational product and for at least 28 days after taking the last dose of investigational product, FCBP who engage in activity in which conception is possible must use one of the approved contraceptive options described below:

Option 1: Any one of the following highly effective contraceptive methods: hormonal contraception (oral, injection, implant, transdermal patch, vaginal ring); intrauterine device (IUD); tubal ligation; or partner's vasectomy.

OR

Option 2: Male or female condom (latex condom or nonlatex condom NOT made out of natural [animal] membrane [for example, polyurethane]); PLUS one additional barrier method: (a) diaphragm with spermicide; (b) cervical cap with spermicide; or (c) contraceptive sponge with spermicide.

The female subject's chosen form of contraception must be effective by the time the female subject is randomized into the study (for example, hormonal contraception should be initiated at least 28 days before randomization).

Exclusion Criteria:

• Subject has a persistent or recurring bacterial infection requiring systemic antibiotics, or clinically significant viral or fungal or helminth parasitic infections, within 2 weeks of the Screening Visit. Any treatment of such infections must have been completed at least 2 weeks prior to the Screening Visit and no new/recurrent infections should have occurred prior to the Baseline Visit.

• Subject has clinically significant (as determined by the investigator) renal, hepatic, hematologic, intestinal, endocrine, pulmonary, cardiovascular, neurological, psychiatric, immunologic, or other major uncontrolled diseases that will affect the health of the subject during the study, or interfere with the interpretation of study results.
• Subject has a suspected or active lymphoproliferative disorder or malignancy; OR a history of malignancy within 5 years before the Baseline assessment, except for completely treated in situ non-melanoma skin and cervical cancers without evidence of metastasis.
• Subject was treated previously with dupilumab.
• Subject has received a live attenuated vaccine ≤ 30 days prior to study initiation.
• History of adverse systemic or allergic reactions to any component of the study drug.
• Severe, untreated asthma or a history of life-threatening asthma exacerbations while on appropriate regimen of anti-asthmatic medications.
• Use of systemic immunosuppressive medications, including, but not limited to, cyclosporine, systemic or intralesional corticosteroids, mycophenolate mofetil, azathioprine, methotrexate, tacrolimus, or ultraviolet (UV) phototherapy with or without Psoralen Ultraviolet A (PUVA) therapy within 4 weeks prior to trial initiation.
• Use of an oral JAK inhibitor (tofacitinib, ruxolitinib) within 12 weeks prior to the Baseline visit.
• Subject has used topical corticosteroids, and/or tacrolimus, and/or pimecrolimus on any keloid lesions within 1 week prior to the Baseline visit. These will be allowed during the study on areas of atopic dermatitis (if applicable) but not on any keloid lesions.
