Phase II Study of RO4929097 to Eradicate Residual Disease in Patients With Multiple Myeloma Post Single Autologous Stem Cell Transplant


I. To determine the efficacy of RO4929097 in eradicating residual/persistent disease
(conversion of VGPR to CR or sCR status) in multiple myeloma patients status post single
high-dose melphalan/autologous stem cell rescue with residual/persistent disease


I. To determine the safety of single agent RO4929097 post-autologous stem cell transplant in
multiple myeloma patients.

II. To analyze Notch receptor and ligand protein expression in pre-transplant, pre-treatment
with RO4929097, and post-treatment bone marrow biopsy samples.

III. To isolate and identify clonogenic multiple myeloma progenitor cells from bone marrow
aspirate and/or peripheral blood at the following time points: pre-transplant, day 100
post-transplant, and post-treatment staging bone marrow biopsy.

IV. To analyze Notch receptor and ligand protein expression on isolated clonogenic
progenitor myeloma cells.

V. To characterize the tumor xenograft-initiating potential of clonogenic myeloma cells in
adult Casper zebrafish and SCID-hu model and evaluate the drug toxicity and therapeutic
potential of RO4929097 with this model.

VI. To analyze anti-angiogenic effects of RO4929097 as measured by reduction in microvessel
density and VEGFR-1 expression in pre-treatment and post-treatment bone marrow biopsy

VII. To determine whether measurement of soluble surrogate markers of angiogenesis prior to
and following treatment with RO4929097 provide an early marker of disease response to Notch

OUTLINE: This is a multicenter study.

STEM CELL TRANSPLANTATION AND CHEMOTHERAPY: Patients undergo standard mobilization and
collection of autologous peripheral stem cells (>= 4.0 x 10^6 CD34+ cells/kg). Patients then
receive high-dose melphalan IV on days -3 and -2 and undergo autologous stem cell
transfusion on day 0. Patients with progressive disease, stable disease, partial response,
stringent complete response, or complete response are taken off study; patients with
residual/persistent disease (very good partial response [VGPR]*) continue to therapeutic

NOTE: *Patients who meet the criteria for VGPR but have findings of abnormal bone marrow
cytogenetic study demonstrating >= 10% metaphase cells positive for either high-risk
chromosomal abnormalities or persistent disease-related chromosomal abnormalities (e.g.,
chromosome del 13; del17p, t(4;14), t(14;16), t(6;14) or complex cytogenetics) will have a
repeat bone marrow biopsy assessment with cytogenetics within 2-3 weeks. If the repeat
biopsy findings suggest persistent high-risk cytogenetic findings, then the patient is
considered eligible to receive RO4929097 to eradicate residual disease.

THERAPEUTIC TREATMENT: Beginning 100-110 days after transplantation, patients receive oral
RO4929097 once daily on days 1-3, 8-10, and 15-17. Courses repeat every 21 days in the
absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for at least 4 weeks.

Inclusion Criteria:

- Patients must have a diagnosis of multiple myeloma as defined below with staging
based on the International Staging System:

- Multiple myeloma - all three required (Note: these criteria identify stage 1B
and stages II and IIIA/B myeloma by Durie/Salmon stage; stage 1A becomes
smoldering or indolent myeloma):

- Monoclonal plasma cells in the bone marrow ≥ 10% and/or presence of a
biopsy-proven plasmacytoma

- Monoclonal protein present in the serum and/or urine (if no monoclonal
protein is detected [non-secretory disease], then >= 30% monoclonal bone
marrow plasma cells and/or biopsy-proven plasmacytoma is required)

- Myeloma-related organ dysfunction (1 or more) (a variety of other types of
end organ dysfunctions can occasionally occur and lead to a need for
therapy; such dysfunction is sufficient to support classification as
myeloma if proven to be myeloma related):

- Calcium elevation in the blood (serum calcium > 10.5 mg/L or upper
limit of normal)

- Renal insufficiency (serum creatinine > 2mg/dL)

- Anemia (hemoglobin < 10 g/dL or 2 g < normal)

- Lytic bone lesions or osteoporosis (if a solitary [biopsy-proven]
plasmacytoma or osteoporosis alone [without fractures] are the sole
defining criteria, then > 30% plasma cells are required in the bone

- Patients must have measurable disease

- Patients with non-secretory multiple myeloma will be eligible only if the
baseline serum free light chain level is elevated (>= 10 mg/dL)

- For therapeutic treatment with RO4929097, patients must have peripheral blood stem
cell collection of >= 4.0 x 10^6 cells/kg (patient's ideal body weight)

- ECOG performance status =< 2, Karnofsky >= 60%

- Estimated life expectancy of at least 12 weeks

- Absolute neutrophil count (ANC) >= 1,500/mcL

- Platelets >= 100,000/mcL

- Hemoglobin >= 9.0 g/dL

- NOTE: Patients should not require chronic supportive growth factor administration or
transfusions to meet treatment eligibility criteria (e.g., G-CSF for ANC eligibility)

- Serum creatinine =< 2.0 mg/dL OR a measured creatinine clearance by 24-hour urine
collection >= 40 mL/min (a calculated creatinine clearance by Cockcroft-Gault formula
is acceptable in lieu of a measured value)

- Total bilirubin within normal institutional limits

- AST (SGOT)/ALT SGPT) =< 2.5 X institutional ULN

- Patients with uncontrolled electrolyte abnormalities including hypocalcemia,
hypomagnesemia, hyponatremia, hypophosphatemia, or hypokalemia, defined as less than

- Negative pregnancy test

- Fertile patients must use two forms of contraception (i.e., barrier contraception and
one other method of contraception) at least 4 weeks prior to study entry, for the
duration of study participation, and for at least 12 months post-treatment

- No requirement for routine use of hematopoietic growth factors (including granulocyte
colony-stimulating factor, granulocyte-macrophage colony-stimulating factor, or
interleukin-11) or platelet transfusions to maintain absolute neutrophil counts or
platelet counts above the required thresholds for study entry
