trioxide may induce cell death
(apoptosis) and normalization (differentiation) thru novel pathway(s). Approved for

Bendamustine
Bendamustine is an alkylating agent with a nitrogen mustard group
and a purine-like benzimidazol group. It has shown activity
against refractory lymphomas - lymphomas resistant to treatment.

Bryostatin
Possible mechanism of action: "Bryostatin-1 is believed to
bind to the regulatory domain of the PKC enzyme suggesting a
mechanism of action distinct from other kinase modulators in
development." -

GvHD
Graft vs. Host Disease (GvHD) - a frequent
complication of allogeneic bone marrow transplant in which the donor's bone
marrow cells attacks the patient's organs and tissue. GvHD tends to be more
severe in patients receiving mismatched transplants from family member and
in patients receiving unrelated donor transplants. See GvHD
for more detail.

Immune-based studies
"Lenalidomide... may decrease the production of
cytokine and growth factors decreasing the growth of the cells or
new blood vessels for the cells. ... it could also improve
the function of natural killer T cells, and enhance immunity.
Lenalidomide is currently approved by the FDA for the treatment of
multiple myeloma, another type of cancer that affects circulating
plasma cells, which produce antibodies. Lenalidomide is currently
awaiting FDA approval for CLL and NHL."

Nonmyeloablative therapy is sometimes
called a mini transplant, adoptive immunotherapy, or non-ablative transplant.
With this treatment relatively low dose
of chemotherapy are used to suppress the patient's immune system enough to
prevent rejection of the donor cells and control the lymphoma. The
pre-transplant regimen (chemo) must suppress the lymphoma
sufficiently to prevent marked progression of the tumor and allow
time for the Graft vs. Tumor
(GVT) effect to occur -- which relies on the killing action of the donor’s immune
cells to eradicate the remaining disease.

Targeted agents
Targeted
therapy is a type of medication
that blocks the growth of cancer
cells by interfering with specific targeted molecules
needed for carcinogenesis
and tumor
growth, rather than by simply interfering with rapidly dividing cells.
Targeted cancer therapies may be more effective than current
treatments and less harmful to normal cells.
The main categories of targeted therapy are small molecules and monoclonal
antibodies.

Agents that target pathways in malignant cells
that resist apoptosis
Antisense (anti-bcl-2) (Oblimersen sodium, Genasense)
Antisense therapy inhibits cell production of bcl-2, a protein
that is thought to inhibit cell death and increase resistance to
cancer therapies. Thus, the goal of antisense therapy is to
sensitize cancer cells to cancer treatments. It may also have
activity as a single agent.

Bortezomib
for NHL (Velcade / PS-341)
(Recently approved for Multiple
Myeloma and Mantle Cell Lymphoma.)
The goal of this investigative treatment type is to inhibit the breakdown of
proteins in the malignant cells, which produce and require the
elimination of more proteins than normal cells.

Enzastaurin
(LY317615), an acyclic bisindolylmaleimide, is an oral inhibitor of the protein kinase
Cbeta isozyme.
"In many cancers, mTOR is
inappropriately “switched on” due to the abnormal activation
of one or more of the upstream signaling pathways that regulate
mTOR activity. As a result, mTOR’s ability to inhibit protein
synthesis and cause growth arrest when nutrients are scarce
becomes compromised." Background

CDDO
"CDDO is a novel synthetic triterpenoid which is a potent multifunctional molecule. It induces apoptosis in vitro in malignant cells through both intrinsic and extrinsic pathways, and it controls cellular differentiation, apoptosis, and growth inhibition by serving as a ligand for the transcription factor peroxisome proliferator activator receptor- gamma (PPAR
gamma ). "

"The mitotic kinesin KSP plays an exclusive and essential
role in assembly and function of the mitotic spindle. KSP
represents a novel target for development of therapeutics against
cancer. SB-715992 is a unique and selective inhibitor of KSP, that
is preferentially overexpressed in malignant cells, functions
exclusively in mitosis, and is not expressed in terminally
differentiated neurons." - ASCO
