Primary Outcome Measures For Clinical Trial:

  • Safety, tolerability,and dose limiting toxicities will be determined using AEs,PE,ophthalmologic examinations,clinical laboratory tests,vital signs, ECGs and echocardiograms/MUGA scans. [ Time Frame: with in the first 28 days after initiation of once daily oral dosing ] [ Designated as safety issue: No ]

Secondary Outcome Measures For Clinical Trial:

  • Establish recommended Phase 2 dose, after completing dose escalation in Part 1 and evaluating accumulated safety,PK,and PD data from the dose escalation phase (Part1) [ Time Frame: Completion of Part 1 dose escalation phase of study ] [ Designated as safety issue: No ]
    After completion of observation for dose limiting toxicities in Part 1 of the study, the accumulated safety, PK, and PD data from Part 1 will be evaluated by the investigators and Sponsor to select a preliminary RP2D for administration to additional subjects to be enrolled into 1 of 3 independent and non-randomized diagnosis-specific expansion cohorts in Part 2 of the study

  • evaluate the Pharmacokinetic parameters of AVL-292 [ Time Frame: First 28 days of dosing ] [ Designated as safety issue: No ]
    Serial blood sampling to enable PK characterization of AVL-292 will be performed for the Cycle1 Day 1 (C1D1) and Cycle 1Day 15 dose administrations. Additional samples will be obtained on C1D8 and C1D22.A non-compartmental model will be evaluated for all subjects.

  • evaluate the Pharmacodynamics of AVL-292 by measurement of free Btk [ Time Frame: First 28 days of dosing ] [ Designated as safety issue: No ]
    The PD activity of AVL-292 will be studied with a quantitative assay using a covalent probe to directly assess free Btk in PBMC lysates.

  • Characterize preliminary anti-tumor efficacy of AVL-292 in relapsed and/or refractory B-NHL, CLL and WM [ Time Frame: After completion of 28 day cycle of treatment ] [ Designated as safety issue: No ]
    Efficay response assessments will be formally assessed within 7 days preceding C2D1, C3D1, C5D1, C7D1, and EOT

Assigned Study Interventions

Experimental: AVL-292 Drug: AVL-292

125 mg to 625 mg orally, once a day, for 28 days (28 days equals 1 cycle). Number of cycles: until progression or unacceptable toxicity develops
Other Name: Btk inhibitor

Detailed Description:

Bruton’s tyrosine kinase (Btk) is non-receptor tyrosine kinase with restricted cellular expression largely limited to B-lymphocytes, monocytes, and mast cells or basophils. Btk is a critical component of the B cell receptor (BCR) signaling network and is crucial for B cell development. Investigation has revealed that some B cell lymphomas and CLL depend on BCR signaling, suggesting that interruption of such signaling could be a promising therapeutic opportunity in B-NHL, CLL and WM.
