What is the OPTiM trial?
OPTiM is a Phase 3 clinical study of OncoVEXGM-CSF in
people with stages III and IV of melanoma. OncoVEXGM-CSF is
an investigational agent, which means it has not been approved
by the FDA or other regulatory agencies outside of the US
for general use (i.e., by prescription).
The goal of OPTiM is to find out whether OncoVEXGM-CSF can
provide an effective treatment for people with melanoma.
OPTiM is being conducted in the United States and Europe
for eligible male or female participants 18 years of age or older.
It is a controlled study, meaning that some participants will
get OncoVEXGM-CSF and
some will get the control (subcutaneously administered GM-CSF).
Participants will be randomly assigned (like flipping a coin)
to receive OncoVEXGM-CSF or GM-CSF.
Two-thirds of the participants will receive OncoVEXGM-CSF and
one-third will receive GM-CSF. The study is "unblinded" such
that both the study subject and the study physician will know
whether the study subject is receiving OncoVEXGM-CSF or
GM-CSF. Every two weeks OncoVEXGM-CSF will
be injected into one or more of the study subject's melanoma;
there are no planned overnight stays. Subjects given GM-CSF will
be given injections every day for two weeks and then have two
weeks off. After treatment ends, there will be periodic follow-up
contacts for a total of 2 years after the study subject receives
the first dose of OncoVEXGM-CSF or
GM-CSF.
What is OncoVEXGM-CSF?
OncoVEXGM-CSF is a novel biologic
drug that is a combined
- oncolytic virus (a reprogrammed virus that
has been converted into a cancer-fighting agent that attacks
cancerous cells, while leaving healthy cells undamaged)
and
- vaccine (a biological preparation that establishes
or improves immunity to a particular disease) approach to treating
advance melanoma.
The oncolytic virus component is a special strain of herpes
simplex type 1 (HSV-1) virus that has been reprogrammed
to infect only cancer cells. So the OncoVEXGM-CSF virus
is disabled in its ability to infect normal healthy cells.
The immune boosting component is the human GM-CSF gene that is
put into the genetic material of the HSV-1 virus. OncoVEXGM-CSF is
injected every 2 weeks into melanoma sites on the skin, just
under the skin (subcutaneous) or other tumor locations that can
be reached by injecting through the skin (such as lymph nodes).
GM-CSF is the name of the "control" drug that may
be given to you if you take part in this research study. GM-CSF
has been used in studies with patients with melanoma, but it
has not been approved by the FDA for this use.
GM-CSF will be injected just under your skin (called a 'subcutaneous'
injection).
Who can enroll in the trial?
This is a list of some of the criteria for entry into
the trial.
- Males or females age ≥ 18 years
- Confirmed diagnosis
of malignant melanoma
- Stage IIIb, IIIc or stage IV disease that cannot be cured
by surgery
- Measurable disease (the study doctor has to be
able to measure the disease to see if the disease responds)
- Injectable disease (OncoVEXGM-CSF has to be injected directly
into tumors)
Where are the study sites?
