Phase II Study of KW2871 Combined With High Dose Interferon-α2b in Patients With Metastatic Melanoma

Completed · Phase 2

Conditions studied: Metastatic Melanoma, Cutaneous Melanoma

In brief

This was a Phase 2, open-label study of KW2871 (ecromeximab) in combination with high-dose interferon-α2b (HDI) in patients with metastatic melanoma. The primary objectives of this study were to assess progression-free survival (PFS) and safety. The secondary objectives were to assess the objective response rate, KW2871 pharmacokinetics (PK), and other exploratory immunology as indicated (e.g., development of human anti-chimeric antibodies \[HACA\], activity of antibody-dependent cell-mediated cytotoxicity \[ADCC\] and complement-dependent cytotoxicity \[CDC\] in peripheral blood, number and functional state of tumor-infiltrating immune cells and expression of GD3 in immune and tumor cells of tumor biopsies, and markers of interferon \[IFN\] response/resistance and markers of resistance to ADCC/CDC in peripheral blood mononuclear cells \[PBMCs\]).

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Age ≥ 18 years of age.
Histologically proven metastatic cutaneous, mucosal, or unknown primary melanoma.
Measurable disease using Response Evaluation Criteria in Solid Tumors (RECIST).
Ambulatory (Eastern Cooperative Oncology Group [ECOG] performance status 0 or 1) or expected survival ≥ 4 months.
Within the last 2 weeks prior to study day 1, the following laboratory parameters within the ranges specified:
Hemoglobin: ≥ 9 g/dL
Platelets: ≥ 100 x 10\^9/L
Neutrophils: ≥ 1.5 x 10\^9/L
International normalized ratio: ≤ 2.0 (≤ 3.0 if on warfarin therapy)
Serum creatinine: ≤ 1.5 x upper limit of normal (ULN)
Serum total bilirubin: ≤ 1.5 x ULN
Aspartate aminotransferase/alanine aminotransferase: ≤ 2.5 x ULN
Able and willing to give valid written informed consent.

You may not qualify if…

Other malignancy within 3 years prior to study entry for which the patient received active treatment, except for treated melanoma or non-melanoma skin cancer, cervical cancer, and breast carcinoma in situ.
Mental impairment that may have compromised the ability to give informed consent and comply with the study requirements.
Participation in any other clinical trial involving chemotherapy, radiotherapy, or other immunotherapy within 4 weeks prior to study enrollment.
Prior exposure to anti-GD3 antibodies.
Pregnancy or breastfeeding.
Women of childbearing potential who refused or were unable to use effective means of contraception.
Active autoimmune or other disorders that required systemic treatment with immunomodulatory or immunosuppressant medications (i.e., corticosteroids, cyclophosphamide, methotrexate, other biologics). Corticosteroids at substitution doses were allowed.
Metastatic brain disease was allowed provided that appropriate treatment had been administered (surgery or irradiation) and 2-month follow-up by brain magnetic resonance imaging (MRI) showed disease control (stability or regression).
Autoimmune-related hypothyroidism and vitiligo-like depigmentation were allowed provided the patient was medically stable with treatment (thyroid-hormone replacement or observation).
Serious medical illness, such as cardiovascular disease (uncontrolled congestive heart failure or hypertension, active ischemic disease of the heart [angina], recent [<3 months] myocardial infarction, severe cardiac arrhythmia), bleeding disorders, obstructive or restrictive pulmonary diseases, active systemic infections requiring antibiotics, serious intercurrent illness requiring hospitalization, inflammatory bowel disorders, or significant psychiatric disease, which in the opinion of the principal investigator would have prevented adequate informed consent or rendered study treatment unsafe or contraindicated.
Patients with clinical suspicion of human immunodeficiency virus (HIV) or hepatitis underwent the following viral tests: patients with HIV must have had negative antibodies; patients with hepatitis B virus must have had negative antigens; patients with hepatitis C virus must have had a negative test for serum antibodies. If any of the tests were positive, patients were excluded from the study.
