Safety, Immunogenicity and Pharmacokinetics of SYN004 in Patients With Solid Tumors

Completed · Phase 1

Conditions studied: Colon Cancer, Breast Cancer, Cancer of the Head and Neck

In brief

A first-in-human evaluation of SYN004, a monoclonal antibody that binds to the EGF receptor on cancer cells. Cetuximab, a marketed antibody, has been shown to be effective by inhibiting the growth of cancer cells thereby prolonging the life of patients who have received it. SYN004 is a closely related monoclonal antibody also binds to the EGF receptor in the same way. SYN004 might also inhibit cancer cells and prolong life but has been engineered to avoid some of the hypersensitivity reactions known to provoked by cetuximab.

• Ability to communicate with the investigator, and understand and comply with the requirements of the protocol;
• Agrees to notify the investigator when deviating from the protocol requirements with regard to concomitant medications;
• Agrees to stay in contact with the study site for the duration of the study and to provide updated contact information as necessary, and has no current plans to move from the study area for the duration of the study.

You may not qualify if…

• Participation in a study of an investigational agent or use of an investigational device at the time of screening or within 4 weeks of enrollment;
• Receipt of treatment with a monoclonal antibody (mAb) within 4 weeks of enrollment or not recovered from an adverse event (i.e., event is >Grade 1 or subject has not returned to baseline) due to treatment with a mAb administered >4 weeks before enrollment;
• Receipt of chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to enrollment, or not recovered from an adverse event (i.e., event is >Grade 1 or subject has not returned to baseline) due to a previously-administered agent;
• Major surgical procedure or significant traumatic injury within 4 weeks prior to screening;
• Diagnosis of an additional malignancy that is progressing and requires treatment; exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, and in situ cervical cancer that has undergone potentially curative therapy;
• Active autoimmune disease requiring systemic treatment within the past 3 months, or a documented history of severe autoimmune disease, or a syndrome that requires systemic steroids or immunosuppressive agents (subjects with vitiligo or resolved childhood asthma/atopy are allowed);
• Diagnosis of an immune deficiency;
• Receipt of systemic steroids or any form of immunosuppressive therapy within 7 days prior to enrollment, with the following exceptions:
• Stable doses of topical, ocular, intranasal or inhaled corticosteroids
• Doses of systemic steroids that, in the opinion of the investigator, are pysiologic replacement doses
• Systemic steroids as prophylactic treatment for subjects with allergy to contrast media
• Non-absorbed intra-articular steroid injections
• Systemic corticosteroids required for control of infusion reactions or AEs if doses have been tapered to <10 mg prednisone or equivalent for 2 weeks prior to the first study treatment
• Evidence of interstitial lung disease or active, non-infectious pneumonitis;
• Active infection requiring systemic therapy;
• History of cerebrovascular accident, transient ischemic attack, or subarachnoid hemorrhage within 6 months prior to screening;
• Active hepatitis B (i.e., hepatitis B surface antigen [HBsAg] positive) or hepatitis C (i.e., hepatitis C virus [HCV] ribonucleic acid [RNA; qualitative] is detected);
• Serious non-healing wound, ulcer, or bone fracture;
• Any severe or uncontrolled medical condition or other condition that could affect participation in the study;
• Any current medical, psychiatric, occupational, or substance abuse problems that, in the opinion of the investigator, will make it unlikely that the subject will comply with the protocol.
