A phase I trial of azacitidine and nanoparticle albumin bound paclitaxel in patients with advanced or metastatic solid tumors.

Background: Secreted protein acidic and rich in cysteine (SPARC), an albumin-binding protein, is downregulated by hypermethylation in many cancers. Hypomethylating agents such as azacitidine can upregulate SPARC in tumors, which may enhance the accumulation of albumin-bound drugs at tumor site. The objectives of this phase I trial was to determine the safety and maximum tolerated dose and to assess any clinical activity of the combination of azacytidine and weekly nanoparticle-albumin-bound (nab®) paclitaxel.

A Phase I Study of Neoadjuvant Chemotherapy With Nab-Paclitaxel, Doxorubicin, and Cyclophosphamide in Patients With Stage II to III Breast Cancer.

Background: The aims of this study were to assess the safety and tolerability of nanoparticle albumin bound paclitaxel (nab-paclitaxel), doxorubicin, and cyclophosphamide as combination therapy for breast cancer patients in the neoadjuvant setting and to assess the overall clinical response and pathologic complete response (pCR).

Patients And Methods: Twenty-six women with newly diagnosed stage II to III histologically or cytologically proven adenocarcinoma of the breast with negative HER2 status were enrolled. Patients were treated with nab-paclitaxel 100 mg/m, doxorubicin 50 mg/m, and cyclophosphamide 500 mg/m on day 1 and nab-paclitaxel 100 mg/m on day 8 in a 21-day cycle for 6 cycles total.

Phase II trial of hyper CVAD and dasatinib in patients with relapsed Philadelphia chromosome positive acute lymphoblastic leukemia or blast phase chronic myeloid leukemia.

Dasatinib is a second generation tyrosine kinase inhibitor, with activity in imatinib resistant Ph-positive ALL.We have treated 34 patients with relapsed Philadelphia chromosome positive acute lymphoblastic leukemia(ALL) (n519) or lymphoid blast phase of chronic myelogenous leukemia (CML-LB) (n515) with the combination of dasatinib and the hyper CVAD regimen. Prior regimens included hyper CVAD plus imatinib(n511, 4 had transplant in first CR), other combination chemotherapy (n512), monotherapy with kinase inhibitors other than dasatinib (n59), and investigational agents (n52).

Enhanced histone deacetylase enzyme activity in primary myelofibrosis.

We measured histone deacetylase (HDAC) activity in 17 patients with primary myelofibrosis (PMF); 19 with other myeloproliferative neoplasm (MPN) and 16 normal volunteers. Significantly elevated HDAC levels were shown in patients with PMF compared with other MPN patients and normal volunteers (p<0.05).
