A Phase I Study of OncoLAR® (Registered Trademark) (NSC 685403) With/Without Tamoxifen in Patients With Osteosarcoma

Completed · Phase 1

Conditions studied: Neoplasm Metastasis, Osteosarcoma

In brief

The suppression of IGF-I and growth hormone may significantly alter the pathobiology of osteosarcoma. SMS 201-955 pa LAR is a long acting analog of Somatostatin which inhibits the pituitary release of growth hormone, reducing levels of circulating IGF-I . Additional data on tamoxifen usage has also demonstrated a reduction in circulating IGF-I levels. The degree of suppression of IGF-I and growth hormone will be determined at two dose levels of SMS 291-955 pa LAR. Tamoxifen will be added to two of the cohorts to determine if the additive effects of tamoxifen and SMS 201-955 pa LAR will lead to additional reduction of circulating IGF-I and growth hormone levels. Arginine-stimulated GH tests to assess levels of growth hormone in the blood will be administered pre-treatment evaluation up to three times, one time on weeks 2, 8, 16, 28, 40, 52, and one month post last dose of SMS 201-955 pa LAR. The four cohorts for this study will receive 60 or 90 mg SMS 201-955 pa LAR injectable every four weeks for up to 52 weeks. Two of the cohorts will receive 10 mg Tamoxifen on a daily basis.
