Inclusion Criteria

Patients with a persistent and clinically significant aPL profile

Patients with at least 1 of the following non-criteria manifestations of APS:

1. aPL-nephropathy (diagnosed by kidney biopsy within 12 months of Screening) confirmed based on the updated APS Classification Criteria recommendations, and urine protein to creatinine ratio > 1.0 at the time of the Screening visit and/or
2. Skin ulcers (non-infected livedoid vasculitis-like skin ulcer and/or large skin ulceration resembling pyoderma gangrenosum) for at least 4 weeks prior to the Screening visit, diagnosed by physical examination, and/or
3. Persistent active thrombocytopenia (diagnosed by platelet counts <100 x 103/μL and ≥20 x 103/μL [SI: <100 x 109/L and ≥ 20 x 109/L]) and confirmed at the time of screening (at least 4 weeks after previous test) based on the updated APS Classification Criteria recommendations Patients and spouse/partner who is of childbearing potential must be using highly effective contraception consisting of 2 forms of birth control (at least 1 of which must be a barrier method) starting at Screening and continuing through the entire study.

Patients with aPL-nephropathy must be receiving or agree to initiate an ACE inhibitor or angiotensin receptor blocker at least 4 weeks prior to initiation of ALXN1007 treatment; unless patient is documented to be intolerant. Patients receiving oral corticosteroids must be on a stable dose of ≤ 10 mg/day of prednisone or equivalent dose of another corticosteroid preparation for at least 4 weeks prior to the first dose of ALXN1007. Patients receiving immunosuppressive medications (including but not limited to methotrexate, hydroxychloroquine, azathioprine, cyclosporine and mycophenolate mofetil) must be on a stable dose for at least 4 weeks prior to the first dose of ALXN1007. Patients receiving oral anticoagulants or antiplatelet agents (including but not limited to aspirin) must be on stable doses for at least 4 weeks prior to first dose of ALXN1007.

Patients must be willing and able to give written informed consent and to comply with all study visits and procedures.

Patients with skin ulcers from causes other than aPL or who are positive for DVT or venous insufficiency at Screening. Patients with renal function status requiring chronic dialysis (defined as dialysis on a regular basis as renal replacement therapy).
