Phase 1b/2, Multicenter Open-label Study of the Safety and Activity of Carfilzomib in Subjects With Relapsed Solid Tumors, Multiple Myeloma or Lymphoma
Inclusion Criteria:
Disease related
Phase 1 Subjects (Bolus and Infusion):
Solid Tumor:
- Histologically confirmed advanced solid tumor
- 1 to 3 prior treatment regimens
- At least one site of radiographically measurable disease of ≥ 2 cm in the largest
dimension by traditional computerized tomography (CT) scanning technique or ≥ 1 cm in
the largest dimension by spiral CT scanning (per RECIST criteria); or if, in the
Principal Investigator's opinion, evaluable disease can be reliably and consistently
followed, the subject may be eligible upon approval by the Medical Monitor
Multiple Myeloma:
- Relapsed and/or refractory multiple myeloma following 2 or more prior treatment
regimens.
- Measurable disease as indicated by one or more of the following:
- Serum M-protein ≥ 1 g/dL
- Urine M-protein ≥ 200 mg/24 hr
- Serum Free Light Chain: Involved free light chain (FLC) level ≥ 10 mg/dL provided
serum FLC ratio is abnormal
Lymphoma:
- Histologically or cytologically confirmed lymphoma.
- Patients must have had an initial diagnosis of indolent NHL (including follicular,
small lymphocytic, lymphoplasmacytoid, and marginal zone lymphoma), indolent disease
that transformed to a more aggressive subtype, as previously described or patients
may have mantle cell lymphoma.
- Patients are required to have received prior rituximab (alone or combined with other
treatment) and are considered refractory to (defined as no response, or progression
within 6 months of completing therapy) or intolerant of continued rituximab.
- Patients may have received up to a maximum of four prior unique chemotherapy
regimens, including if not contra-indicated autologous stem-cell transplantation
(ASCT).
- For patients to enroll in the expanded dose group for lymphoma, patients must have
measurable disease
Phase 2 Bolus Subjects:
-Histologically confirmed advanced solid tumor diagnosis and:
- NSCLC: Failed at least 1 prior platinum-based chemotherapy regimen but not more than
3 prior therapies for metastatic disease
- SCLC: Failed 1 to 3 prior chemotherapy regimens
- Ovarian: Failed at least 1 prior platinum-based chemotherapy regimen but not more
than 4 therapies for metastatic disease
- Renal: Failed at least 2 prior chemotherapy regimens for metastatic disease
- Other solid tumor types: Failed at least 1 prior chemotherapy regimen for metastatic
or relapsed disease and for which standard of care therapy is no longer effective or
does not exist
- At least one site of radiographically measurable disease of ≥ 2 cm in the largest
dimension by traditional CT scanning technique or ≥ 1 cm in the largest dimension by
spiral CT scanning (per RECIST criteria); or if, in the Principal Investigator's
opinion, evaluable disease can be reliably and consistently followed, the subject may
be eligible upon approval by the Medical Monitor
Demographic
- Males and females ≥ 18 years of age
- Life expectancy of more than 3 months
- Eastern Cooperative Oncology Group (ECOG) Performance Status 0-2
Laboratory
- Adequate hepatic function, with bilirubin 1.5 times the upper limit of normal (ULN),
and alanine aminotransferase (ALT) 3 times ULN
- Absolute neutrophil count (ANC) > 1000/mm3, hemoglobin ≥ 8 gm/dL for solid tumors or
7.0gm/dL for MM, and platelet count ≥ 100,000/ mm3 for solid tumors or ≥ 30,000/mm3
for MM.
- Subjects should not have received platelet transfusions for at least 1 week
prior to screening
- Screening ANC should be independent of granulocyte- and granulocyte/macrophage
colony stimulating factor (G-CSF and GM-CSF) support for at least 1 week and of
pegylated G CSF for ≥ 2 weeks
- Subjects may receive red blood cell (RBC) transfusions or receive supportive
care with erythropoietin or darbepoetin in accordance with institutional
guidelines
- Calculated or measured creatinine clearance (CrCl) of ≥ 20 mL/minute calculated using
the formula of Cockcroft and Gault [(140 - Age) x Mass (kg) / (72 x Creatinine
mg/dL)]. Multiply result by 0.85 if female. Subjects with calculated CrCl < 20
mL/min may be allowed, only with prior approval by the Medical Monitor.
Ethical/Other
- Written informed consent in accordance with federal, local, and institutional
guidelines
- Female subjects of childbearing potential must have a negative serum or urine
pregnancy test within 3 days of the first dose and agree to use dual methods of
contraception during the study and for 3 months following the last dose of study
drug. Post-menopausal females (>45 years old and without menses for > 1 year) and
surgically sterilized females are exempt from these requirements. Male subjects must
use an effective barrier method of contraception during the study and for 3 months
following the last dose if sexually active with a female of childbearing potential.
Exclusion Criteria:
Disease Related
- Chemotherapy with approved or investigational anticancer therapeutics, including
steroid therapy, within 3 weeks prior to first dose or 6 weeks for antibody therapy
- Radiation therapy or immunotherapy within 3 weeks prior to first dose (except for
antibody therapy, where 6 weeks is required); localized radiation therapy within 1
week prior to first dose
- Subjects with prior brain metastases are permitted, but must have completed treatment
and have no evidence of active central nervous system (CNS) disease for at least 4
weeks prior to first dose
- For lymphoma patients; patients with prior stem cell transplant therapy (autologous
SCT within the prior 8 weeks; allogeneic SCT within the prior 16 weeks). Patients
with prior allogeneic SCT should not have evidence of moderate-to-severe GvHD (as
defined in Filipovich et al 2005).
- Evidence of CNS lymphoma
- Participation in an investigational therapeutic study within 3 weeks prior to first
dose
- Prior treatment with carfilzomib
Concurrent Conditions
- Major surgery within 3 weeks prior to first dose
- Congestive heart failure (New York Heart Association class III to IV), symptomatic
ischemia, conduction abnormalities uncontrolled by conventional intervention, or

first dose
- Subjects with pleural effusions requiring routine thoracentesis or ascites requiring
routine paracentesis
- Subjects at risk* in whom the required program of oral and intravenous fluid
hydration is contraindicated, e.g., due to pre-existing pulmonary, cardiac, or renal
impairment
- High risk for Tumor Lysis Syndrome.
Ethical / Other
- Female subjects who are pregnant or lactating
- Any clinically significant psychiatric or medical condition that in the opinion of
the Investigator could interfere with protocol adherence or a subject's ability to
give informed consent
