Phase 1 Clinical Trial of a Novel CDK Inhibitor Dinaciclib (SCH 727965) in Combination With Bortezomib and Dexamethasone in Relapsed Multiple Myeloma

This phase I trial studies the side effects and best dose of dinaciclib and bortezomib when
given together with dexamethasone in treating patients with multiple myeloma that has
returned after a period of improvement. Dinaciclib and bortezomib may stop the growth of
cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in
chemotherapy, such as dexamethasone, work in different ways to stop the growth of cancer
cells, either by killing the cells, by stopping them from dividing, or by stopping them from
spreading. Giving dinaciclib and bortezomib together with dexamethasone may kill more cancer
cells.

PRIMARY OBJECTIVES:

I. To determine the maximally tolerated doses of dinaciclib and bortezomib, when used in
combination, in two different schedules, for treatment of relapsed multiple myeloma.

SECONDARY OBJECTIVES:

I. To determine the toxicities associated with dinaciclib and bortezomib, when used in
combination, for treatment of relapsed multiple myeloma.

II. To determine the overall response rate associated with dinaciclib and bortezomib, when
used in combination, for treatment of relapsed multiple myeloma.

III. To explore the differences in toxicity associated with two different schedules of
dinaciclib and bortezomib used in combination.

TERTIARY OBJECTIVES:

I. To examine if expression levels of target cyclin dependent kinase (CDK): CDK 2,5,7 and 9
levels in cluster of differentiation (CD)138-purified tumor cells, will be correlated with
response (clinical and molecular) to determine if high or low level target CDK expression,
if present, influences dinaciclib efficacy.

II. To examine if immunoglobulin (Ig)H translocation status, P53 status and presence of
v-myc myelocytomatosis viral oncogene homolog (avian) (Myc) amplification or rearrangement,
determined on patient bone marrow before treatment, using a pre validated fluorescence in
situ hybridization (FISH) panel to identify common myeloma translocations, will be
correlated with molecular and/or clinical markers of drug activity, and to assess if
specific genetic subgroups of myeloma tumors are responsive or resistant.

III. To determine the gene expression profiles of myeloma cells before and after treatment
to understand the role of tumor gene dysregulation and/or dinaciclib induced effects on
transcription.

OUTLINE: This is a dose-escalation study of dinaciclib and bortezomib. Patients are assigned
to 1 of 2 treatment schedules.

SCHEDULE I: Patients receive dinaciclib intravenously (IV) over 2 hours and bortezomib
subcutaneously (SC) or IV (if patients do not tolerate SC injection) on days 1, 8, and 15
and dexamethasone orally (PO) once daily (QD) on days 1, 2, 8, 9, 15, and 16. Courses repeat
every 28 days in the absence of disease progression or unacceptable toxicity.

SCHEDULE II: Patients receive dinaciclib IV over 2 hours on day 1; bortezomib SC on days 1
and 8; and dexamethasone PO QD on days 1, 2, 8, and 9. Courses repeat every 21 days in the
absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and 3 months.

Inclusion Criteria:

standard treatment regimens

- Measurable disease of multiple myeloma as defined by at least ONE of the following:

- Serum monoclonal protein >= 1 g/dL

- >= 200 mg of monoclonal protein in the urine on 24 hour electrophoresis

- Serum immunoglobulin free light chain >= 10 mg/dL and abnormal serum
immunoglobulin kappa to lambda free light chain ratio

- Monoclonal bone marrow plasmacytosis >= 30% (evaluable disease)

- Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0, 1 or 2

- Adequate residual organ function per treating physician discretion; Note: there is no
limit with regard to the number of prior therapies

- Provide informed written consent

- Negative pregnancy test done =< 7 days prior to registration, for women of
childbearing potential only

- Willing to provide samples for correlative research purposes

- Willing to return to consenting institution for follow-up during the study

- Recovered (i.e., =< grade 1 toxicity) from the reversible effects of prior
antineoplastic therapy

Exclusion Criteria:

- Any of the following recent therapies:

- Alkylators (e.g. melphalan, cyclophosphamide) =< 14 days prior to registration

- Anthracyclines =< 14 days prior to registration

- High dose corticosteroids, immune modulatory drugs (thalidomide or
lenalidomide), or proteosome inhibitors (bortezomib) =< 7 days prior to
registration

- Concomitant high dose corticosteroids (concurrent use of corticosteroids); EXCEPTION:
patients may be on chronic steroids (maximum dose 20 mg/day prednisone equivalent) if
they are being given for disorders other than amyloid, i.e., adrenal insufficiency,
rheumatoid arthritis, etc.

- Other active malignancy =< 2 years prior to registration; EXCEPTIONS: non-melanotic
skin cancer or carcinoma in-situ of the cervix; NOTE: if there is a history of prior
malignancy, they must not be receiving other specific treatment for their cancer

- Any of the following:

- Pregnant women or women of reproductive ability who are unwilling to use 2
effective methods of contraception from the time of signing the informed consent
form through 30 days after the last dose of study drug

- Nursing women

vasectomy) while having intercourse with any woman, while taking the drug and
for 30 days after stopping treatment

- Other co-morbidity which would interfere with patient's ability to participate in
trial, e.g. uncontrolled infection, uncompensated heart or lung disease

- Other concurrent chemotherapy, radiotherapy, or any ancillary therapy considered
investigational; NOTE: bisphosphonates are considered to be supportive care rather
than therapy, and are thus allowed while on protocol treatment
