NCI-V96-1050

Objectives

I.  Compare the progression-free interval following treatment with 
moderate-dose LGD1069 vs. high-dose LGD1069 vs. placebo in patients with stage 
IIIB/IV or recurrent non-small cell lung cancer that is stable or responding 
following combination chemotherapy with a platinum compound plus a taxane, 
etoposide, or a vinca alkaloid.

II.  Evaluate the safety and tolerability of LGD1069 in these patients.

III.  Document objective antitumor responses to LGD1069 in patients with 
measurable or evaluable disease.

IV.  Compare patient survival and quality of life in these three treatment 
groups.

Entry Criteria

Disease Characteristics:


Histologically confirmed, incurable non-small cell lung cancer in one of the
following categories:

 At least 1 month since prior investigational agents
 No concurrent drugs that significantly alter hepatic or renal metabolism
  unless dose stable
 No concurrent vitamin A in excess of 15,000 IU/day

  No second malignancy within 5 years except nonmelanomatous skin cancer
  No pregnant or nursing women
     Negative pregnancy test required of fertile women within 7 days prior to
     entry
  Effective contraception (including abstinence) required of fertile patients
     for 4 weeks prior to, during, and for at least 3 months after treatment


Expected Enrollment

A total of 90 patients will be entered in the Phase II portion of this 
multicenter study.

Outline

This is a randomized, double-blind study.  Patients are stratified by 
participating institution.

Patients are randomly assigned to receive daily oral treatment with high-dose 
LGD1069, moderate-dose LGD1069, or placebo.  Patients in the placebo group are 
evenly divided to receive approximately 7 or 14 capsules per day.

Treatment in all groups continues until disease progression or unacceptable 
toxicity intervenes.  Upon disease progression, patients may receive 
alternative therapy at the investigator's discretion.

No concurrent radiotherapy, hormonal therapy (including progestational agents 
for appetite stimulation), chemotherapy, immunotherapy, or investigational 
therapies.  Chronic low-dose replacement hormone therapy or low-dose 
corticosteroids for noncancer-related conditions are allowed.

Patients are followed every 2 weeks for 1 month, then every 4 weeks during 
treatment, at 4 weeks after the last dose, then for survival.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
