Carcinoma, Non-Small-Cell Lung Clinical Trial
— PLASMAOfficial title:
Phase II Study of AZD9291 in Patients With Advanced Stage Non-small Cell Lung Cancer Following Prior EGFR TKI Therapy With EGFR and T790M Mutations Detected in Plasma Circulating Tumor DNA (PLASMA)
Circulating tumor DNA (ctDNA) is a highly specific and effective biomarker for the detection
of EGFR mutation status. We hypothesise AZD9291 is efficacious in patients with EGFR
sensitizing mutations and T790M detected in plasma ctDNA.
This is a prospective, open label, multi-centre single arm phase II study assessing the
efficacy and safety of AZD9291 monotherapy in patients with stage IIIB or IV harboring
sensitising EGFR mutation (exon 19 deletions or exon 21 L858R substitution mutations) and
T790M who have progressed following prior treatment with an approved EGFR TKI. Approximately
106 subjects will be enrolled.
All patients must have documented radiological progression on EGFR-TKI treatment and on the
last treatment administered prior to enrolling in the study.

Locally advanced/metastatic NSCLC not amenable to curative surgery or radiotherapy 4. Documentation of activating EGFR mutations (exon 19 deletions or exon 21 L858R substitution mutations) at the time of initial diagnosis 5. Radiological documentation of disease progression: following 1st line EGFR TKI treatment but who have not received further treatment OR following prior therapy with an EGFR TKI and a platinum-based doublet chemotherapy. All patients must have documented radiological progression on the last treatment administered prior to enrolling in the study. 6. Patient may receive up to two lines of therapies (including EGFR TKI). 7. Plasma sample must harbour an EGFR mutation known to be associated with EGFR TKI sensitivity (exon 19 deletion, L858R). Confirmation of T790M status by central lab testing from a plasma sample taken after confirmation of disease progression on the most recent treatment regimen. 8. Patients must have normal organ and bone marrow function measured within 28 days prior to administration of study treatment as defined below: - Haemoglobin >= 10.0 g/dL and no blood transfusions in the 28 days prior to entry - Absolute neutrophil count (ANC) >= 1.5 x 109/L - No features suggestive of MDS/AML on peripheral blood smear - White blood cells (WBC) > 3x109/L - Platelet count >= 100 x 109/L - Total bilirubin <= 1.5 x institutional upper limit of normal (ULN) - AST (SGOT)/ALT (SGPT) <= 2.5 x institutional upper limit of normal unless liver metastases are present in which case it must be <= 5x ULN - Serum creatinine <= 1.5 x institutional upper limit of normal (ULN) - ECOG performance status 0-2 9. Patients must have a life expectancy >= 12 weeks. 10. Females should be using adequate contraceptive measures, should not be breast feeding and must have a negative pregnancy test prior to start of dosing if of child-bearing potential or must have evidence of non-child-bearing potential by fulfilling one of the following criteria at screening: - Post-menopausal defined as aged more than 50 years and amenorrheic for at least 12 months following cessation of all exogenous hormonal treatments - Women under 50 years old would be consider postmenopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and with LH and FSH levels in the post-menopausal range for the institution - Documentation of irreversible surgical sterilisation by hysterectomy, bilateral oophorectomy or bilateral salpingectomy but not tubal ligation 11. Male patients should be willing to use barrier contraception (see Restrictions, Section 5.1) 12. Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up. 13. At least one lesion, not previously irradiated, that can be accurately measured at baseline as >= 10 mm in the longest diameter (except lymph nodes which must have short axis >= 15 mm) with computed tomography (CT) or magnetic resonance imaging (MRI) and which is suitable for accurate repeated measurements Exclusion Criteria: 1. Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site) 2.

Major surgery within 4 weeks of starting study treatment and patients must have recovered from any effects of any major surgery. 12. Patients currently receiving (or unable to stop use prior to receiving the first dose of study treatment) medications or herbal supplements known to be potent inhibitors of CYP3A4 (at least 1 week prior) and potent inducers of CYP3A4 (at least 3 week prior) (Appendix A). All patients must try to avoid concomitant use of any medications, herbal supplements and/or ingestion of foods with known inducer/inhibitory effects on CYP3A4. 13. Any evidence of severe or uncontrolled systemic diseases, including uncontrolled hypertension and active bleeding diatheses, which in the investigator's opinion makes it undesirable for the patient to participate in the trial or which would jeopardise compliance with the protocol, or active infection including hepatitis B, hepatitis C and human immunodeficiency virus (HIV). Screening for chronic conditions is not required. 14. Past medical history of ILD, drug-induced ILD, radiation pneumonitis requiring steroid treatment, or any evidence of clinically active ILD 15. Any of the following cardiac criteria: 1. Mean resting corrected QT interval (QTc using Fredericia's formula) > 470 msec 2. Any clinically important abnormalities in rhythm, conduction or morphology of resting ECG (e.g., complete left bundle branch block, third degree heart block, second degree heart block) 3. Any factors that increase the risk of QTc prolongation or risk of arrhythmic events such as heart failure, hypokalemia, congenital long QT syndrome, family history of long QT syndrome or unexplained sudden death under 40 years of age in first degree relatives or any concomitant medication known to prolong the QT interval 16. Refractory nausea and vomiting, chronic gastrointestinal diseases, inability to swallow the formulated product or previous significant bowel resection that would preclude adequate absorption of AZD9291 17. History of hypersensitivity to AZD9291 (or drugs with a similar chemical structure or class to AZD9291) or any excipients of these agents 18. Males and females of reproductive potential who are not using an effective method of birth control and females who are pregnant or breastfeeding or have a positive serum pregnancy test prior to study entry 19.
