Expanded Access: Programs and Possibilities
Current Expanded Access Programs
top of the pageThe FDA requires that all cancer expanded access programs be listed on the government
website www.clinicaltrials.gov.
To directly access information on Expanded Access programs that are open for enrollment,
from the ClinicalTrials.gov home page, click on "Search for Clinical Trials." You will then
see a page called "Basic Search" with an open box for you to enter the topic of your interest.
Skip this and instead, click on the "Advanced Search" tab at the top of the page. This will open
a page with many open boxes. Ignore all of them except the fourth entitled "Study Type" which will
have the term "All Studies" filled in. Use the drop-down button to select "Expanded Access Studies."
Then go to the fifth open box entitled "Conditions" and type in the word "Cancer." Then push the "Search"
button. This will take you to the page listing both older closed and new open Expanded Access Programs for
various types of cancer approved by the FDA. Note that if you are interested in an Expanded Access program
for a condition other than cancer, you can either leave the box blank to see all programs for all conditions,
or fill in the name of the condition you are looking for.

Currently Open Expanded Access Programs
The best source of up-to-date information on open expanded access programs is the ClinicalTrials.gov site.
We highlight some interesting programs here, but our listing is not complete nor updated as often as the government site.
T-DM1 for Treatment of certain types of Metastatic Breast Cancer
T-DM1 (more completely known as Trastuzumab-DM1) is an antibody-drug conjugate
developed by Genentech in association with ImmunoGen. An antibody-drug conjugate is
composed of an antibody linked to a drug in a manner that allows the drug to be released
once the antibody binds to its target. In this case, the antibody used is called
trastuzumab, also known by the product name Herceptin, which targets HER2-positive breast
cancer cells. The drug that is linked to the antibody is called mertansine and it
interferes with tubulin, a protein essential for cell division. The idea of an
antibody-drug conjugate is to enable potent doses of a highly toxic drug to be targeted
precisely to only the cells that need to be killed, in this case HER2-positive breast
cancer cells, without doing too much damage to normal cells.
In a Phase II clinical trial, T-DM1 shrank tumors in one-third of women who had received
extensive prior treatment for advanced HER2-positive breast cancer. In some cases, T-DM1
was useful even for women whose disease progressed during treatment with Herceptin.
Genentech has numerous clinical trials of T-DM1 underway or planned. An expanded access study
entitled “An Expanded Access, Open-Label Study of Trastuzumab-MCC-DM1 Administered Intravenously
to Patients With HER2- Positive Locally Advanced or Metastatic Breast Cancer”"T-DM1 Patient Access
Study" is open in the United States while T-DM1 is under FDA
review for marketing approval.
Go to www.clinicaltrials.gov for more information on this Expanded Access Program,
including contact information and eligibility criteria. The formal title of the program is "A Study of
Trastuzumab-MCC-DM1 in Patients With HER2-Positive Locally Advanced or Metastatic Breast
Cancer."
RO5185426 for Treatment of a subset of Metastatic Melanoma
This drug has shown significant promise for people with metastatic melanoma with the BRAF
V600E mutation. There are expanded access programs for this product in both the United States
and internationally. Details are available on the ClinicalTrials.gov site.
Carfilzomib for Treatment of certain types of Relapsed and Refractory Multiple Myeloma
This is a multi-center, expanded access, open label study of carfilzomib for patients with relapsed and refractory multiple myeloma.
The study is designed to provide access to patients with relapsed and refractory disease that have received at least 4 prior
regimens and are not eligible for any other enrolling carfilzomib Onyx-sponsored studies enrolling patients in the United States.
Check the ClinicalTrials.gov site for details.
Experimental Drugs in Phase 3 Clinical Trials
top of the pageRemember:
- No cancer drug works for every patient who uses it
- Most cancer drugs have significant side effects
- We don't know if a new treatment will be better than the existing treatment until comparison trials are complete.
There are some new drugs - for example, Gleevec - which offer a dramatic improvement to standard treatments. Unfortunately, most new drugs don't fall into that category.
Experimental drugs in phase 3 clinical trials are generally the drugs closest to FDA review and possible approval. Companies tend to be most open to considering access outside of trials for drugs at this stage of development.
Remember, you cannot force companies to allow access. However, your call may get them thinking about either expanded access or single patient use. Contact us for help.
New Uses for Old Drugs
top of the pageCompanies may apply to the FDA for approval of their drug in new forms of cancer, based on clinical trial results. This approval means that treatment for the new form of cancer is considered non-experimental and your insurance will cover costs.
