In lymphocytes, the phosphoinositide 3'-kinase (PI3K) isoform p110δ (PI3Kδ) transmits signals from surface receptors, including the B-cell receptor (BCR). CAL-101, a selective inhibitor of PI3Kδ, displays clinical activity in CLL, causing rapid lymph node shrinkage and a transient lymphocytosis. Inhibition of pro-survival pathways, the presumed mechanism of(More)
PURPOSE Interstitial cystitis is a painful bladder condition of unknown etiology and poorly understood pathophysiology. Current therapies have met with limited success. Vanilloid receptor agonists such as resiniferatoxin (RTX) desensitize C-fibers that transmit pain; it is hypothesized that such drugs will be effective in the treatment of interstitial(More)
Both entecavir (ETV) and tenofovir (TDF) are potent antiviral agents for hepatitis B virus (HBV). Suboptimal response (SOR) following antiviral therapy is associated with an increased risk of subsequent treatment failure and viral resistance. It remains unclear whether switching to TDF is a reasonable approach in patients with SOR to ETV treatment. This(More)
(-)-Epigallocatechin-3-gallate (EGCG), the major polyphenol in green tea, has been shown to inhibit tumorigenesis and cancer cell growth in animal models. Nevertheless, the dose-response relationship of the inhibitory activity in vivo has not been systematically characterized. The present studies were conducted to address these issues, as well as the(More)
Apolipoprotein E (ApoE) has been recently identified as a potential tumor-associated marker in ovarian cancer by serial analysis of gene expression. ApoE has long been known to play a key role in lipid transport, and its specific isoforms may participate in atherosclerogenesis. However, its role in human cancer is not known. In this study, apoE expression(More)
Formononetin, an active constituent of the Chinese herb Astragali Radix, has been reported to have beneficial effects for Alzheimer's disease (AD). Yet the mechanism of this effect remains to be elucidated. The present study shows that formononetin increases soluble-AβPPα (sAβPPα) secretion and thus protects human-AβPP Swedish mutation cell (N2a-AβPP cell)(More)
3543 Background: The class I PI3Ks regulate a variety of cellular functions relevant to oncogenesis, including metabolism, proliferation and survival. The PI3K p110δ isoform is highly expressed in cells of hematopoietic origin and plays a key role in B cell maturation and function. CAL-101 is a potent inhibitor of PI3K p110δ (IC50=65 nM) with 40 to 300-fold(More)
OBJECTIVE To evaluate the safety, pharmacokinetics, pharmacodynamics, and immunogenicity of a humanized anti-CD11/CD18 monoclonal antibody (Hu23F2G) in patients with multiple sclerosis. METHODS In this phase I uncontrolled dose escalation study, patients (n = 24) with primary or secondary progressive multiple sclerosis received single intravenous(More)
Idelalisib, an oral inhibitor of phosphatidylinositol-3-kinase δ (PI3Kδ), was evaluated in a 48-week phase 1 study (50-350 mg daily or twice daily) enrolling 40 patients with relapsed or refractory mantle cell lymphoma (MCL). Primary outcome was safety and dose-limiting toxicity (DLT). Secondary outcomes were pharmacokinetic parameters, pharmacodynamic(More)
• Idelalisib was evaluated in 54 patients with heavily pretreated chronic lymphocytic leukemia, and target inhibition was documented in vivo. • Oral idelalisib therapy demonstrated a favorable safety profile and rapidly induced durable disease control in the majority of patients. In a phase 1 trial, idelalisib (GS-1101, CAL-101), a selective inhibitor of(More)
