Brief summary: This is a Phase I, open-label, multicenter, dose-escalation trial of VS-5584, a PI3K/mTOR kinase inhibitor, in subjects with advanced non-hematologic malignancies or lymphoma. This clinical study is comprised of 2 sequential parts: Part 1 (Dose Escalation) and Part 2 (Expansion). The purpose of this study is to evaluate the safety (including the recommended Phase II dose), pharmacokinetics (the amount of VS-5584 in subject's blood) and the anti-cancer activity of VS-5584. Biomarkers (genes or proteins that may predict or show how subject's body may respond to VS-5584) will also be assessed in archival tumor tissue, tumor biopsies (in consenting subjects), and blood samples.


Eligibility criteria: Inclusion Criteria:

1. Able to provide signed and dated informed consent prior to initiation of any study procedures.
2. Age ≥ 18 years.
3. Subjects must have a histopathologically confirmed diagnosis of an advanced non-hematologic malignancy or lymphoma or indolent NHL/CLL.
4. Subjects must have no alternate therapy of proven benefit or have refused standard therapy.
5. All clinically significant toxicities from prior chemotherapy must be ≤ Grade 1.
6. ECOG performance status of 0 or 1, measured at screening and immediately before the start of treatment.
7. Predicted life expectancy of ≥ 3 months.
8. Fasting blood glucose of ≤ 140 mg/dL (7.8 mmol/L).
9. Adequate renal function \[creatinine ≤ 1.5x ULN (upper limit of normal)\] or GFR of ≥ 60mL/min.
10. Adequate hepatic function (total bilirubin ≤ 1.5x ULN for the institution; AST \[aspartate transaminase\] and ALT \[alanine transaminase\] ≤ 3x ULN).
11. Adequate bone marrow function (hemoglobin ≥ 9.0 g/dL; platelets ≥ 75 x10\^9 cells/L; absolute neutrophil count ≥ 1.0x10\^9 cells/L).
12. Corrected QT interval (QTc) \< 470 ms (as calculated by the Fridericia correction formula).
13. Negative pregnancy test for women of child-bearing potential.
14. Men and women of child bearing potential must agree to use adequate birth control throughout their participation in the study and for 60 days following the last study treatment.
15. Willing and able to participate in the trial and comply with all trial requirements.
16. Subjects must have archival tumor tissue available for mutational analysis. A study specific biopsy can be performed if archival tissue is not available.
17. Stable brain metastases either treated or being treated with a stable dose of steroids/ anticonvulsants, with no dose change within 28 days prior to the first dose of study drug, will be allowed.

Exclusion Criteria:

1. Gastrointestinal (GI) condition which could interfere with the swallowing or absorption of study medication.
2. Uncontrolled or severe concurrent medical condition including cardiovascular disease (e.g., myocardial infarct, unstable angina, New York Heart Association (NYHA) Class II or greater congestive heart failure, serious arrhythmias requiring medication for treatment, clinically significant pericardial disease, cardiac amyloidosis, transient ischemic attacks, CVA, coronary artery or other vascular stents).
3. A past history of, or current uncontrolled hypertension. Blood pressure must be adequately controlled prior to dosing with VS-5584.
4. Prior history of a hypertensive reaction to a kinase inhibitor
5. History of upper gastrointestinal bleeding, ulceration, or perforation within 12 months prior to the first dose of study drug.
6. Subjects with known infection with human immunodeficiency virus (HIV) or Acquired Immune Deficiency Syndrome (AIDS) (testing not required).
7. Subjects with known active Hepatitis A, B or C (testing not required).
8. Subjects being actively treated for a secondary malignancy.
9. Cancer-directed therapy (chemotherapy, radiotherapy, hormonal therapy with the exception of LHRH agonists for prostate cancer, biologic or immunotherapy, etc.) within 21 days of the first dose of study drug or 5 half-lives, whichever is shorter. Palliative radiotherapy is allowed prior to initiating treatment if associated toxicity resolved to ≤ Grade 1.
10. Subjects currently taking medications known to be strong CYP3A4 inhibitors.
11. Major surgery within 28 days prior to the first dose of study drug.
12. Subjects with acute or chronic pancreatitis.
13. Subjects with diabetes mellitus requiring insulin treatment or subjects with a HbA1C \> 7.
14. Use of an investigational drug within 28 days or 5 half-lives (whichever is shorter) prior to the first dose of study drug. A minimum of 14 days between termination of the investigational drug and administration of the study treatment is required. In addition, any drug-related toxicity except alopecia should have recovered to grade 1 or less.
15. Women who are pregnant or breastfeeding.
16. Any evidence of serious active infections.
17. Uncontrolled intercurrent illness involving any other organ system or a social situation that would, in investigator's opinion, place the subject at unacceptable risk, limit compliance, or confound interpretation of safety or other results.

Primary outcomes:
measure: Assess the safety and tolerability of VS-5584 in subjects with advanced non-hematologic malignancies or lymphoma
timeFrame: From start of treatment to end of treatment, an expected average of 6 weeks
measure: Determine the maximum tolerated dose (MTD) and the recommended phase 2 dose (RP2D) and schedule of VS-5584 administered to subjects with advanced non-hematologic malignancies or lymphoma
timeFrame: From start of treatment to end of Cycle 1 (21 day cycles)
Secondary outcomes:
measure: Assess the pharmacokinetics of VS-5584
timeFrame: Time points on Day 1, 2, 3, 17, 18
Other outcomes:
measure: Evaluate the efficacy of VS-5584
timeFrame: Every 6 weeks to end of treatment, expected average of 6 weeks
measure: Evaluate the time to new lesion
timeFrame: Expected average of 6 weeks from start of treatment to end of treatment
measure: Evaluate duration of response to VS-5584 compared with duration of response to prior therapy
timeFrame: Expected average of 6 weeks from start of treatment to end of treatment
