Official Title
A Dutch National Study on Behalf of the CPCT to Facilitate Patient Access to Commercially Available, Targeted Anti-cancer Drugs to Determine the Potential Efficacy in Treatment of Advanced Cancers With a Known Molecular Profile
Brief Title
The Drug Rediscovery Protocol (DRUP Trial)
Protocol ID
NCT02925234
Lead Sponsor
The Netherlands Cancer Institute
Brief Summary
This is a prospective, non-randomized clinical trial that aims to describe the efficacy
and toxicity of commercially available, targeted anticancer drugs* prescribed for
treatment of patients with advanced cancer with a potentially actionable variant as
revealed by a genomic or protein expression test. The study also aims to simplify patient
access to approved targeted therapies that are contributed to the program by
collaborating pharmaceutical companies and to perform next generation sequencing on tumor
biopsies for biomarker analyses. Eligible patients have an advanced solid tumor, multiple
myeloma or B cell non-Hodgkin lymphoma for which standard treatment options are no longer
available and acceptable performance status and organ function. A genomic or protein
expression test must have been performed on the tumor and the results must identify at
least one potentially actionable molecular variant as defined in the protocol. Results
from the molecular profiling test will be used to determine an appropriate drug(s) from
among those available in the protocol. The choice of drug will be supported by a list of
potential profiles, a molecular tumor board, a knowledge library and by study
coordinators for review and approval of the match. The protocol-specified treatment will
be administered to the patient once any drug-specific eligibility criteria are confirmed
and a fresh pre-treatment biopsy is performed for future genetic studies. All patients
who receive treatment with a drug available in the protocol will be followed for standard
efficacy outcomes including tumor response, progression-free and overall survival as well
as duration of treatment. In addition, treatment related toxicity will be evaluated.
Detailed Description
Problem description: evidence is building that matching targeted agents to tumor
characteristics can improve outcomes. Such reports have fueled interest among patients
and physicians to use molecular testing for treatment planning when standard treatment
options have been exhausted. When oncologists aim to provide such personalized treatment
to their patients though, obtaining the drugs can be challenging since off-label
prescribing, while legal, is generally not reimbursed by insurance companies.
Furthermore, outcomes of off-label treatment in routine clinical practice are not
systematically recorded. As a result, the research and clinical communities have limited
insight in these outcomes, leading to repetitive use of ineffective treatment for some
tumor types, while effective treatment strategies might be missed for others. The latter
is especially relevant for 'orphan diseases', that are too rare to conduct formal phase
II and III trials. In summary, there is a lack of access to potentially effective therapy
on one hand, and a lack of knowledge on broader use of such therapies on the other,
altogether leading to sub-optimal use of available resources.
Envisioned solution and study aim: creation of a drug-access program, in which patients
are treated with registered targeted therapy matched to their molecular tumor profile,
and in which the outcomes of such therapies are recorded systematically, per tumor
profile and tumor type (this is important since it is becoming increasingly clear that
the tissue of origin is an important determinant of outcome of genetic abnormalities). We
hereby aim to improve and broaden the use of registered targeted therapy, whilst
facilitating patient access to such therapy.
Plan of investigation: patients will be treated with approved targeted agents, selected
based on results of a molecular profiling test of the patient's tumor. Eligible patients
will have exhausted standard treatment options, and their tumor must harbor a potentially
actionable molecular variant as defined in the protocol. The study will provide a tumor
board to help physicians understand the profiling test results and treatment options, and
will enable insights about the utility of this approach. In addition, next generation
sequencing will be performed on fresh tumor biopsies for additional biomarker discovery.
Patients from the Netherlands and the USA will be included in two similar though
independent protocols (DRUP and TAPUR), allowing data-exchange and empowering of both
trials.
Expected outcome: early signs of clinical activity of approved drugs outside their label,
providing effective personalized treatment options, improved patient outcomes and access
to targeted therapy.
Enrollment Count
1,550 participants
Eligibility Criteria
Inclusion Criteria:
1. Adult (age >18 years) patient with a histologically-proven locally advanced or
metastatic solid tumor, multiple myeloma or B cell non-Hodgkin lymphomawith
symptomatic disease progression or progression according to RECIST-criteria after
standard anti-cancer treatment or for whom no such treatment is available or
indicated.
* For patients with a primary brain tumor: Histologically confirmed recurrent or de
novo primary brain tumor, with unequivocal progression after prior therapy, at least
3 months after radiotherapy (either first line chemo-radiotherapy or
re-irradiation), and with stable or decreasing dosage of steroids for at least 7
days prior to the baseline MRI scan.
2. ECOG performance status 0-2
3. Patients must have acceptable organ function as defined below. However, specific
inclusion/exclusion criteria specified in the drug-specific study manual will take
precedence:
1. Absolute neutrophil count ≥ 1.5 x 109/l
2. Hemoglobin > 5.6 mmol/l
3. Platelets > 75 x 109/l
4. Total bilirubin < 2 x ULN
5. AST (SGOT) and ALT (SGPT) < 2.5 x institutional ULN (or < 5 x ULN in patients
with known hepatic metastases)
6. Serum creatinine ≤ 1.5 × ULN or calculated or measured creatinine clearance ≥
50 mL/min/1.73 m2
4. Patients must have objectively measurable disease (by physical or radiographic
examination, according to RECIST v1.1 for patients with solid tumors, or according
to IMWG, Lugano, RANO or GCIG criteria, resp., for patients with multiple myeloma,
non-Hodgkin lymphoma, glioblastoma or ovarian cancer in case of CA125-based
evaluation (please refer to appendices for further details).
5. Results must be available from a tumor genomic or protein expression test. Eligible
tests may include any of the following technologies: fluorescence in situ
hybridization (FISH), polymerase chain reaction (PCR), comparative genomic
hybridization (CGH), next generation sequencing (NGS) or immunohistochemistry (IHC).
The test may have been performed on the primary tumor or a metastatic deposit, in a
diagnostic laboratory or within the context of another CPCT study, and must reveal a
potentially actionable variant as defined in Section 5. The test results (full
pathology or molecular diagnostics report) must be uploaded in the eCRF.
6. Patients must have a tumor profile for which treatment with one of the FDA and / or
EMA approved (or under revision for approval) targeted anti-cancer drugs included in
this study has potential clinical benefit based on preclinical data or clinical
information (see section 5).
7. new (obtained ≤2 months before inclusion, and without any type of anti-cancer
therapy within those ≤2 months) fresh frozen tumor biopsy specimen for extensive
biomarker testing is mandatory before the start of treatment with a targeted agent
included in the protocol. Alternatively, fresh frozen tumor tissue acquired in the
context of a standard care procedure may be used, provided that no systemic
anti-cancer treatment was given between the procedure and start of study treatment
within DRUP.
The following exceptions are made:
a. An exception is made for patients with a primary brain tumor, only if the
mandatory DRUP pre-treatment biopsy for biomarker analysis cannot safely be
obtained:
1. The fresh frozen tumor biopsy sample may be replaced by fresh frozen tumor
tissue, obtained earlier from recurrent disease, as part of standard of care
surgical procedure (i.e., performed at progression)
2. If no fresh frozen tumor tissue is available for NGS, and the risk of obtaining
a new tumor biopsy is considered too high, no biopsy will be required. In this
case, the study coordinators must be informed in advance, and there will be no
reimbursement for the biopsy procedure.
b. In case WGS is performed on tumor tissue outside the context of a clinical trial
before inclusion, and without any type of anti-cancer therapy between the collection
of tissue and inclusion in DRUP, this can replace the DRUP pre-treatment biopsy,
provided that the patient gives consent to use his/her WGS data for biomarker
analysis in DRUP.
c. An exception is made for patients that underwent an allogeneic hematopoietic stem
cell transplantation prior to study enrollment, since this will prevent a correct
WGS analysis due to a mismatch between the biopsy specimen and the required blood
sample.
8. Ability to understand and the willingness to sign a written informed consent
document.
9. For orally administered drugs, the patient must be able to swallow and tolerate oral
medication and must have no known malabsorption syndrome.
10. Because of the risks of drug treatment to the developing foetus, women of
child-bearing potential and men must agree to use adequate contraception (hormonal
or barrier method of birth control; abstinence) for the duration of study
participation, and for four months following completion of study therapy. Male
patients should avoid impregnating a female partner. Male patients, even if
surgically sterilized, (i.e. post-vasectomy) must agree to one of the following:
practice effective barrier contraception during the entire study treatment period
and through 4 months after the last dose of study drug, or completely abstain from
sexual intercourse.
Exclusion Criteria:
1. Ongoing toxicity > grade 2, other than alopecia.
2. Patient is receiving any other anti-cancer therapy (cytotoxic, biologic, radiation,
or hormonal other than for replacement). Required wash out period prior to starting
study treatment is at least two weeks. An exception is made for:
- Patients suffering from CRPC are allowed to continue androgen deprivation
therapy.
- Medications that are prescribed for supportive care but may potentially have an
anti-cancer effect (e.g., megestrol acetate, bisphosphonates). These
medications must have been started ≥ 1 week prior to enrollment on this study.
3. Patient is pregnant or nursing.
4. Patients with known active progressive brain metastases. Patients with previously
treated brain metastases are eligible, provided that the patient has not experienced
a seizure or had a clinically significant change in neurological status within the 3
months prior to registration. All patients with previously treated brain metastases
must be stable for at least 1 month after completion of treatment and off steroid
treatment prior to study enrollment.
* Additional exclusion criteria specific for glioblastoma patients:
1. Patients who require anti-convulsant therapy must be taking non-enzyme inducing
antiepileptic drugs (non-EIAED). EIAED are prohibited. Patients previously on
EIAED must be switched to non-EIAED at least 2 weeks prior to randomization.
2. No radiotherapy within the three months prior to the diagnosis of progression.
3. No radiotherapy with a dose over 65 Gy, stereotactic radiosurgery or
brachytherapy unless the recurrence is histologically proven.
5. Patients with clinically significant preexisting cardiac conditions, including
uncontrolled or symptomatic angina, uncontrolled atrial or ventricular arrhythmias,
or symptomatic congestive heart failure are not eligible.
6. Patients with known left ventricular ejection fraction (LVEF) < 40% are not eligible
7. Patients with stroke (including TIA) or acute myocardial infarction within 3 months
before the first dose of study treatment are not eligible
8. Patients with any other clinically significant medical condition which, in the
opinion of the treating physician, makes it undesirable for the patient to
participate in the study or which could jeopardize compliance with study
requirements including, but not limited to: ongoing or active infection, significant
uncontrolled hypertension, or severe psychiatric illness/social situations.
For each drug included in this protocol, specific inclusion and exclusion criteria (based
on the Package Insert or manufacturers recommendations) may also apply. These can be
found in the supplemental information about each agent included in the drug-specific
study manuals. Drug-specific inclusion and exclusion criteria will take precedence over
the inclusion/exclusion criteria listed above.
