Clinical trial: Targeted Therapy Directed by Genetic Testing in Treating Patients With Advanced Refractory Solid Tumors, Lymphomas, or Multiple Myeloma (The MATCH Screening Trial)

Summary: This phase II MATCH trial studies how well treatment that is directed by genetic testing works in patients with solid tumors or lymphomas that have progressed following at least one line of standard treatment or for which no agreed upon treatment approach exists. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic abnormalities (such as mutations, amplifications, or translocations) may benefit more from treatment which targets their tumor's particular genetic abnormality. Identifying these genetic abnormalities first may help doctors plan better treatment for patients with solid tumors, lymphomas, or multiple myeloma.

Detailed description: PRIMARY OBJECTIVES:
  I. To evaluate the proportion of patients with objective response (OR) to targeted study agent(s) in patients with advanced refractory cancers/lymphomas/multiple myeloma.
  SECONDARY OBJECTIVES:
  I. To evaluate the proportion of patients alive and progression free at 6 months of treatment with targeted study agent in patients with advanced refractory cancers/lymphomas/multiple myeloma.
  II. To evaluate time until death or disease progression. III. To identify potential predictive biomarkers beyond the genomic alteration by which treatment is assigned or resistance mechanisms using additional genomic, ribonucleic acid (RNA), protein and imaging-based assessment platforms.
  IV. To assess whether radiomic phenotypes obtained from pre-treatment imaging and changes from pre- through post-therapy imaging can predict objective response and progression free survival and to evaluate the association between pre-treatment radiomic phenotypes and targeted gene mutation patterns of tumor biopsy specimens.
  OUTLINE:
  STEP 0 (Screening): Patients undergo biopsy along with molecular characterization of the biopsy material for specific, pre-defined mutations, amplifications, or translocations of interest via tumor sequencing and immunohistochemistry. Consenting patients also undergo collection of blood samples for research purposes.
  STEPS 1, 3, 5, 7 (Treatment): Patients are assigned to 1 of 35 treatment subprotocols based on molecularly-defined subgroup. (See Arms Section)
  STEPS 2, 4, 6 (Screening): Patients experiencing disease progression on the prior Step treatment or who could not tolerate the assigned treatment undergo review of their previous biopsy results to determine if another treatment is available or undergo another biopsy. Patients may have a maximum of 2 screening biopsies and 2 treatments per biopsy.
  STEP 8 (Optional Research): Consenting patients undergo end-of-treatment biopsy and collection of blood samples for research purposes.
  After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 1 year.

Eligibility: Inclusion Criteria:
  -  ELIGIBILITY CRITERIA FOR SCREENING BIOPSY (STEP 0)
  -  Women of childbearing potential must have a negative serum pregnancy test within 2 weeks prior to registration; patients that are pregnant or breast feeding are excluded; a female of childbearing potential is any woman, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria:
  -  Has not undergone a hysterectomy or bilateral oophorectomy; or
  -  Has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months)
  -  Women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 4 months after completion of study; should a woman become pregnant or suspect while she or her partner is participating in this study, she should inform her treating physician immediately
  -  Patients must have histologically documented solid tumors or histologically confirmed diagnosis of lymphoma or multiple myeloma requiring therapy and meet one of the following criteria:
  -  Patients must have progressed following at least one line of standard systemic therapy and there must not be other approval/standard therapy available that has been shown to prolong overall survival (i.e. in a randomized trial against another standard treatment or by comparison to historical controls); patients who cannot receive other standard therapy that has been shown to prolong overall survival due to medical issues will be eligible, if other eligibility criteria are met; if the patient is currently receiving therapy, the clinician must have assessed that the current therapy is no longer benefitting the patient prior to enrolling on MATCH, regardless of whether it is considered standard OR
  -  Patients for whose disease no standard treatment exists that has been shown to prolong overall survival
  -  NOTE: No other prior malignancy is allowed except for the following: adequately treated basal cell or squamous cell skin cancer; in situ cervical cancer; adequately treated stage I or II cancer from which the patient is currently in complete remission; any other cancer from which the patient has been disease-free for 5 years
  -  Patients must have measurable disease
  -  Patients must meet the criteria below and have received results from one of the designated outside laboratories indicating a "rare variant" that is an actionable Mutation of Interest (aMOI) for specific select subprotocols.
  -  The following requirements apply:
  -  The outside laboratory specifically notified the site that patient may be a potential candidate for MATCH due to a detected "rare variant"; the outside lab reports are NOT sufficient for this purpose
  -  NOTE: The content and format of these specific notifications for the Outside Assay process will vary depending on the designated outside lab in question, as they are each responsible for their own outreach efforts; it is strongly recommended that the designated outside laboratory be contacted to confirm the format and receipt of this notification prior to registering any patients to Step 0
  -  Patients with an applicable "rare variant" must be able to meet the eligibility criteria for the appropriate subprotocols within 4 weeks following notification of treatment assignment
  -  NOTE: The receipt of this notification (and the start of the associated deadline for Step 1 registration) may occur shortly after Step 0 registration, since these patients will not be submitting tissue for screening purposes; however, for certain "rare variant" arms, submission of archival tissue for central immunohistochemistry (IHC) testing may be required
  -  Registration to Step 0 must occur after stopping prior systemic anti-cancer therapy; there is no specific duration for which patients must be off treatment prior to registration to Step 0, as long as all eligibility criteria are met
  -  There is no particular window of time after notification of potential eligibility from an outside lab in which the patient must be registered to Step 0, but treatment slots will be assigned on a first come, first serve basis to those who do register to Step 0, and are not held for those notified of potential eligibility who do not register to Step 0
  -  Patients may have received other non-targeted, immunotherapy or targeted treatment between the prior genetic testing at the outside lab and registration to Step 0; the decision to stop such treatment in favor of participation in MATCH, if no further clinical benefit is expected, is per the treating physician's discretion; documentation of a lack of response to the prior treatment is not required in these cases
  -  NOTE: Other potential aMOIs that would be eligibility criteria for "NON RARE" arms, as determined by the designated laboratories, are not applicable for this process in MATCH
  -  NOTE: Tumor tissue for the confirmation of "rare variant" by the MATCH assay is to be submitted, preferably from the same time of collection as that evaluated by the designated outside laboratory
  -  Patient must not require the use of full dose coumarin-derivative anticoagulants such as warfarin; low molecular weight heparin is permitted for prophylactic or therapeutic use; factor X inhibitors are permitted
  -  NOTE: Warfarin may not be started while enrolled in the EAY131 study

  -  NOTE: To receive an agent, patient must not have any uncontrolled intercurrent illness such as ongoing or active infection; patients with infections unlikely to be resolved within 2 weeks following screening should not be considered for the trial
  -  Patients must be able to swallow tablets or capsules; a patient with any gastrointestinal disease that would impair ability to swallow, retain, or absorb drug is not eligible
  -  Patients who are human immunodeficiency virus (HIV)-positive are eligible if:
  -  CD4+ cell count greater or equal to 250 cells/mm^3
  -  If patient is on antiretroviral therapy, there must be minimal interactions or overlapping toxicity of the antiretroviral therapy with the experimental cancer treatment; for experimental cancer therapeutics with CYP3A/4 interactions, protease inhibitor therapy is disallowed; suggested regimens to replace protease inhibitor therapy include dolutegravir given with tenofovir/emtricitabine; raltegravir given with tenofovir and emtricitabine; once daily combinations that use pharmacologic boosters may not be used

  -  NOTE: Prostate cancer patients may continue their luteinizing hormone-releasing hormone (LHRH) agonist
  -  NOTE: For patients entering the study via the original screening process, patients may receive non-protocol treatment after biopsy (if clinically indicated) until they receive notification of results; however, lack of response must be documented prior to registration to Step 1; new non-protocol treatment will NOT be permitted as intervening therapy after registration to Step 0; the only intervening treatment permitted is prior therapy that the patient already received prior to Step 0 registration; the decision to stop the intervening non-protocol treatment will be left up to the treating physician if patient has an aMOI; however, patients will need to be off such therapy for at least 4 weeks before receiving any MATCH protocol treatment
  -  NOTE: For patients entering the study via a designated outside laboratory, no intervening systemic non-protocol treatment is permitted after Step 0 registration; all other eligibility requirements still apply to these patients, including the washouts for prior therapy noted above in this section, the time restrictions outlined, and the eligibility criteria for the intended subprotocol
