Brief Summary:
This is a Phase 1, non-randomized, open-label, dose-escalation and expansion study, evaluating the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary clinical antitumor activity of XL114 administered alone orally to subjects with Non-Hodgkin's Lymphoma (NHL). The objectives of the study also include determining the recommended dose (RD) and/or maximum tolerated dose (MTD) of XL114.

    To evaluate the AUC 0-24 of XL114.

  6. Dose-Escalation Stage: Terminal Half-Life [ Time Frame: 4-6 months ]
    To evaluate the terminal half-life of XL114.

  7. Dose-Escalation Stage: Apparent Clearance (CL/F) [ Time Frame: 4-6 months ]
    To evaluate the CL/F of XL114.

  8. Cohort-Expansion Stage: Antitumor Activity of XL114 (Objective Response Rate [ORR]) [ Time Frame: 4-6 months ]
    To evaluate the antitumor activity of XL114 as measured by ORR based on lymphoma-specific response criteria as assessed by a Blinded Independent Radiology Committee (BIRC) for selected cohorts.

  9. Cohort-Expansion Stage: Antitumor Activity of XL114 (Duration of Response [DOR]) [ Time Frame: 4-6 months ]
    To evaluate the antitumor activity of XL114 as measured by DOR based on lymphoma-specific response criteria as assessed by the Investigator or by a Blinded Independent Radiology Committee (BIRC) for selected cohorts.

  10. Cohort-Expansion Stage: Antitumor Activity of XL114 (Progression Free Survival [PFS]) [ Time Frame: 4-6 months ]
    To evaluate the antitumor activity of XL114 as measured by PFS based on lymphoma-specific response criteria as assessed by the Investigator or by a Blinded Independent Radiology Committee (BIRC) for selected cohorts.

  11. Cohort-Expansion Stage: Overall Survival (OS) of XL114 [ Time Frame: 4-6 months ]
    To evaluate duration of overall survival (OS)

  • Cohort-Expansion Stage Cohort B (ABC-DLBCL subtype): Subjects with histologically documented activated B-cell diffuse large B-cell lymphoma (ABC-DLBCL) subtype. Note: De novo or transformed diffuse large B-cell lymphoma (DLBCL) from previously diagnosed indolent lymphoma (eg, follicular lymphoma) is allowed.
  • Cohort-Expansion Stage Cohort C (MCL): Subjects with histologically documented MCL with monoclonal B-cells that show a chromosome translocation t(11;14)(q13;q32) and/or overexpression of cyclin D1.
  • Cohort-Expansion Stage Cohort D (CLL/SLL): Subjects with histologically documented CLL/SLL per the International Workshop on Chronic Lymphocytic Leukemia (iwCLL) guidelines.
