About

This is an open-label multicenter, phase 1-2 study. Following determination of the recommended AEG35156 dose in combination with carboplatin and paclitaxel in the initial Phase 1 part of this study, additional patients will be enrolled in the Phase 2 part of the study to assess the activity of the combination in advanced non small cell lung cancer.

Full description

Apoptotic induction in cancer cells is a sought after therapeutic goal. Most successful anticancer agents activate apoptosis pathways in the cancers they treat. Apoptotic pathways in cells appear to converge on a single family of enzymes, the caspases, which are proteases that dismantle the cell in an orderly, non-inflammatory fashion, resulting in cell death. The X-linked Inhibitor of Apoptosis (XIAP) is the only known cellular inhibitor of caspases, its over expression thereby blocking the principal means of apoptosis. A wide range of evidence indicates that cellular overexpression of members of the IAP family is a fundamental means by which many cancer cells evade death, even in the presence of strong extrinsic (death receptor-mediated) and intrinsic (mitochondria-mediated) apoptotic cues. The inhibition of cellular XIAP activity, specifically in cancer cells under stress and primed for apoptosis by chemotherapeutic agents, is viewed as a powerful means of tipping the balance towards cell death. In particular, XIAP down regulation has been shown to enhance taxane cytotoxicity preclinically. AEG35156 is a second generation antisense which targets XIAP mRNA to lower XIAP levels and the apoptotic threshold of cancer cells, enhancing their sensitivity to intrinsic death and chemotherapy. AEG35156 may thus enhance the anticancer activity of carboplatin and paclitaxel in patients with advanced non small cell lung cancer

Acceptable liver function:
Bilirubin within normal limit
AST (SGOT), ALT (SGPT) and Alkaline phosphatase < 2.0 times the institution's upper limit of normal
Acceptable renal function:
Serum creatinine within normal limits, OR calculated creatinine clearance > 60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal

Exclusion criteria

Prior chemotherapy for metastatic disease.
Patients with prior history of peripheral neuropathy
Patients with hypersensitivity to platinum containing compounds, mannitol or drugs formulated in Chremophor EL.
Active progressive brain metastases including the presence of any related symptoms or need for corticosteroids. A CT or MRI scan of the head is necessary in patients with a history of brain metastases to document the stability of prior lesions.
Known bleeding diathesis
Pregnant or nursing women. NOTE: Women of child-bearing potential must agree to use adequate contraception (sterile or surgically sterile; hormonal or barrier method of birth control; or abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
Men who are unwilling to use acceptable forms of birth control when engaging in sexual contact with women of child bearing potential
Active, uncontrolled bacterial, viral, or fungal infections, requiring systemic therapy
Known infection with HIV, hepatitis B, or hepatitis C
Serious nonmalignant disease that could compromise protocol objectives in the opinion of the investigator and/or the sponsor
Patients who have received any other investigational agent within the last 30 days. Subjects who have used a previous antisense oligonucleotide in the last 90 days will be excluded
Unwillingness or inability to comply with procedures required in this protocol
