lymph node at enrollment, as well, as a repeat bone marrow biopsy (if involved at
diagnosis) after 3 of therapy and at the time of progression and/ or completion of
therapy whichever comes first.
- Have a performance status of 0-1 on the ECOG Performance Scale.
- Demonstrate adequate organ function as defined in Table 1, all screening labs should
be performed within 10 days of treatment initiation.
Hematological Absolute neutrophil count (ANC) =1000 /mcL Platelets =50,000 / mcL (if bone
marrow involvement =30,000 mcL) Hemoglobin =8 g/dL
Renal Serum creatinine OR =1.5 X upper limit of normal (ULN) OR Measured or calculateda =60
mL/min for subject with creatinine levels > 1.5 X institutional Hepatic ULN creatinine
clearance (GFR can also be used in place of creatinine or CrCl)
Hepatic Serum total bilirubin =1.5 X ULN OR Direct bilirubin = ULN for subjects with total
bilirubin levels > 1.5 ULN AST (SGOT) and ALT (SGPT) =2.5 X ULN Albumin >2.0 mg/dL
Coagulation International Normalized =1.5 X ULN unless subject is receiving anticoagulant
therapy as Ratio (INR) or long as PT or PTT is within therapeutic range of intended use
Prothrombin Time (PT) of anticoagulants
Activated Partial =1.5 X ULN unless subject is receiving anticoagulant therapy as
Thromboplastin Time long as PT or PTT is within therapeutic range of intended use (aPTT) of
anticoagulants
aCreatinine clearance should be calculated per institutional standard.
- Female subject of childbearing potential should have a negative urine or serum
pregnancy prior to receiving the first dose of study medication. If the urine test is
positive or cannot be confirmed as negative, a serum pregnancy test will be required.
- Female subjects of childbearing potential should be willing to use 2 methods of birth
control or be surgically sterile, or abstain from heterosexual activity for the course
of the study through 120 days after the last dose of study medication. Subjects of
childbearing potential are those who have not been surgically sterilized or have not
been free from menses for > 1 year.
- Male subjects should agree to use an adequate method of contraception starting with
the first dose of study therapy through 120 days after the last dose of study therapy.
Exclusion Criteria:
- Is currently participating and receiving study therapy or has participated in a study
of an investigational agent and received study therapy or used an investigational
device within 4 weeks of the first dose of treatment.
- Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any
other form of immunosuppressive therapy within 7 days prior to the first dose of trial
treatment.
- Has a known history of active TB (Bacillus Tuberculosis)
- Hypersensitivity to pembrolizumab or any of its excipients.
- Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study
Day 1 or has not recovered (i.e., = Grade 1 or at baseline) from adverse events due to
agents administered more than 4 weeks earlier.
- Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy
within 4 weeks prior to study Day 1 or who has not recovered (i.e., = Grade 1 or at
baseline) from adverse events due to a previously administered agent.
i. Note: Subjects with = Grade 2 neuropathy are an exception to this criterion and may
qualify for the study.
ii. Note: If subject received major surgery, they must have recovered adequately from the
toxicity and/or complications from the intervention prior to starting therapy.
- Has a known additional malignancy that is progressing or requires active treatment.
Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin
that has undergone potentially curative therapy or in situ cervical cancer.
Has active autoimmune disease that has required systemic treatment in the past 2 years
(i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs).
Replacement therapy (eg. thyroxine, insulin, or physiologic corticosteroid replacement
therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic
treatment.
- Has a history of non-infectious pneumonitis that required steroids or has current
pneumonitis.
- Has an active infection requiring systemic therapy.
- Has a history or current evidence of any condition, therapy, or laboratory abnormality
that might confound the results of the trial, interfere with the subject's
participation for the full duration of the trial, or is not in the best interest of
the subject to participate, in the opinion of the treating investigator.
- Has known psychiatric or substance abuse disorders that would interfere with
cooperation with the requirements of the trial.
- Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent
- Has a known history of Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies).
- Has known active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA
[qualitative] is detected).
- Has received a live vaccine within 30 days of planned start of study therapy.
- Has received prior therapy with a PI3K-inhibitor. (Prior therapy with a PI3K-inhibitor
is allowed if it was discontinued for intolerance)
- Is pregnant or breast feeding, or expecting to conceive or father children within the
projected duration of the trial, starting with the screening visit through 120 days
after the last dose of treatment.
- Has known active central nervous system (CNS) disease and/or lymphomatous involvement.
Subjects with previously treated CNS lymphoma and/or lymphomatous meningitis may
participate provided they are stable (without evidence of progression by imaging for
at least four weeks prior to the first dose of trial treatment and any neurologic
symptoms have returned to baseline), have no evidence of new or enlarging brain
metastases, and are not using steroids for at least 7 days prior to trial treatment
Note: Seasonal influenza vaccines for injection are generally inactivated flu vaccines
and are allowed; however intranasal influenza vaccines (e.g., Flu-Mist®) are live
attenuated vaccines, and are not allowed.
