Brief summary: This phase II MATCH treatment trial evaluates the effectiveness of osimertinib (AZD9291) in treating patients with cancer that has certain genetic changes called EGFR mutations. Osimertinib is in a class of medications called kinase inhibitors. It works by blocking the action of mutant forms of the EGFR protein, which play a key role in tumor cell growth. Osimertinib may cause tumor cell death and inhibit tumor growth in EGFR-overexpressing tumor cells, thereby stopping or slowing the spread of tumor cells.

Detailed description: PRIMARY OBJECTIVE:

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:

Patients receive osimertinib (AZD9291) orally (PO) once daily (QD) on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo radiologic evaluation throughout the trial, echocardiography (ECHO) or multigated acquisition scan (MUGA) during screening, and biopsy and collection of blood samples on trial and at end of treatment.

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 1 year.

THE MATCH SCREENING TRIAL:

Please see NCT02465060 for information on the MATCH Screening Protocol and applicable documents.

Eligibility criteria: Inclusion Criteria:

* Patients must have met applicable eligibility criteria in the Master MATCH Protocol EAY131/ NCI-2015-00054 prior to registration to treatment subprotocol
* Patient must fulfill all eligibility criteria outlined in MATCH Master Protocol at the time of registration to treatment step (step 1, 3, 5, 7)
* Patients must have either of the below, or another aberration, as determined via the MATCH Master Protocol:

  * Any malignancy except non-small cell lung cancer (NSCLC) with EGFR T790M identified in their tumor, with or without an activating mutation OR
  * Any malignancy harboring any of the following mutations: EGFR G719A, G719C, G719D, G719S EGFR L861Q, S786I or an EGFR exon 19 in frame insertion mutation
* Patients must have an electrocardiogram (ECG) within 8 weeks prior to treatment assignment and must have no clinically important abnormalities in rhythm, conduction or morphology of resting ECG e.g. complete left bundle branch block, third degree heart block, and second-degree heart block
* Patients must have an ECHO or a nuclear study (MUGA or first pass) within 4 weeks prior to registration and must not have a left ventricular ejection fraction (LVEF) \< institutional lower limit of normal (LLN). If the LLN is not defined at a site, the LVEF must be \> 50% for the patient to be eligible
* Patients must not have known hypersensitivity to osimertinib (AZD9291) or compounds of similar chemical or biologic composition or any of the inactive excipients of the tablets
* Patient must not have received osimertinib (AZD9291), WZ4002, CO-1686, HM61713, EGF816 or ASP8273 previously
* Patients known to harbor germline EGFR T790M mutations are excluded from the study. Prospective testing for germline mutations is not required
* Patients must not have a history of interstitial lung disease, idiopathic pulmonary fibrosis, organizing pneumonia (eg, bronchiolitis obliterans), drug-induced pneumonitis, idiopathic pneumonitis, radiation pneumonitis requiring steroids, or evidence of active pneumonitis on screening chest computerized tomography (CT) scan. History of radiation pneumonitis in the radiation field (fibrosis) is permitted
* Patients must not currently be receiving treatment with potent CYP3A4 inducters or medications "known to prolong" the QT interval. Drugs that "may possibly prolong" the QT interval, are permitted if the patient has been stable on therapy for the period indicated for the specific medication
* Patients must agree to not donate sperm from the start of protocol treatment until at least 4 months after the last dose of protocol treatment

Primary outcomes:
measure: Objective Response Rate
timeFrame: Tumor assessments occurred at baseline, then every 2 cycles for the first 26 cycles and every 3 cycles thereafter until disease progression, up to 3 years post registration
Secondary outcomes:
measure: 6-month Progression-Free Survival (PFS) Rate
timeFrame: Assessed at baseline, then every 2 cycles for the first 26 cycles, and every 3 cycles thereafter until disease progression, up to 3 years post registration, from which 6-month PFS rate is determined
measure: Progression Free Survival
timeFrame: Assessed at baseline, then every 2 cycles for the first 26 cycles and every 3 cycles thereafter until disease progression, up to 3 years post registration
