Merck Sharp & Dohme (MSD)

Status and phase: Completed; Phase 2

Conditions: Carcinoma, Non-Small-Cell Lung; Breast Neoplasms

Details and patient eligibility

About

To determine the activity of SCH 727965 in participants with breast cancer and in participants with nonsmall-cell lung cancer (NSCLC) compared to standard treatment. The standard treatment used is capecitabine for breast cancer and erlotinib for NSCLC. The study will also determine the activity of SCH 727965 treatment in participants who experience cancer progression after standard treatment.

Enrollment: 97 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Age >=18 years, either sex, any race.

• Histologically or cytologically confirmed breast cancer or NSCLC; and radiographic or clinically advanced disease.

• BREAST CANCER:

  • participant must have previously received both a taxane and an anthracycline (unless anthracycline therapy is contraindicated) in the adjuvant and/or metastatic setting,
  • participant with HER2-positive disease must have progressed after trastuzumab and concomitant or subsequent lapatinib,
  • participant must have received at least one, but no more than two prior regimens for recurrent or metastatic disease (endocrine and biologic therapies do not count as chemotherapeutic regimens).

• NSCLC: at least one, but no more than two prior chemotherapeutic regimens for advanced disease.

• Measurable disease by the RECIST.

• Eastern Cooperative Oncology Group performance status of 0, 1, or 2.

• Adequate hematologic, renal, and hepatic organ function and laboratory parameters.

• Ability to swallow tablets.

Exclusion criteria

• Known brain metastases. For NSCLC only, a participant with central nervous system metastasis is eligible provided the participant has received definitive local therapy (ie, radiation therapy or surgery), has stopped receiving treatment with corticosteroids, and is without symptoms for at least 4 weeks before randomization.

• History of previous radiation therapy to >25% of total bone marrow.

• Known HIV infection.

• Known active hepatitis B or hepatitis C.

• Previous treatment with SCH 727965 or other cyclin-dependent-kinase inhibitors.

• BREAST CANCER:

  • known dihydropyrimidine dehydrogenase deficiency,
  • previous treatment with capecitabine.

• NSCLC: previous treatment with erlotinib.
