Lung Cancer Clinical Trial
Aurora Kinase Inhibitor LY3295668 in Combination With Osimertinib for the Treatment of Advanced or Metastatic EGFR-Mutant Non-squamous Non-small Cell Lung Cancer
This phase Ib/II trial studies the side effects and best dose of aurora A kinase inhibitor LY3295668 when given together with osimertinib in patients with EGFR-mutant non-squamous non-small cell lung cancer that has spread to other places in the body (advanced or metastatic). Aurora A kinase inhibitor LY3295668 and osimertinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving aurora A kinase inhibitor LY3295668 in combination with osimertinib may help control EGFR-mutant non-squamous non-small cell lung cancer.
I. To evaluate dose-limiting toxicity (DLT) and to establish the recommended phase II dose (RP2D) of aurora A kinase inhibitor LY3295668 (LY3295668) given in combination with osimertinib in patients with advanced EGFR-mutant non-small cell lung cancer (NSCLC).
II. To preliminarily assess efficacy of LY3295668 plus osimertinib in advanced EGFR-mutant NSCLC who progressed on prior EGFR tyrosine kinase inhibitor (TKI). The co-primary endpoints are progression-free survival (PFS) at 6 months after treatment and best objective response rate (BRR) within 6 months after treatment.
I. Determine the objective response rate (ORR) with osimertinib LY3295668 combination.
II. Determine the overall survival (OS) with osimertinib LY3295668 combination. III. Determine the disease control rate (DCR) with osimertinib LY3295668 combination.
IV. Determine the safety and tolerability with osimertinib LY3295668 combination.
I. Explore the association of baseline genomic profiles (from tumor, germline deoxyribonucleic acid [DNA], and circulating tumor [ct]DNA) with clinical benefit in patients treated with osimertinib LY3295668 combination.
II. Explore resistance mechanisms to osimertinib LY3295668 combination. III. Determine the immunomodulatory effects of osimertinib LY3295668 combination.
Patients receive osimertinib orally (PO) once daily (QD) and aurora A kinase inhibitor LY3295668 PO twice daily (BID) on days 1-28. Treatment repeats every 28 days for 24 cycles (2 years) in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days and then every 4 months thereafter.

Prior treatment with cytotoxic chemotherapy or immunotherapy is allowed. Up to 3 lines of prior therapy is allowed.
Patients must have adequate hematologic, coagulation, hepatic, and renal function. All laboratory tests must be obtained less than 4 weeks from study entry. This includes:
ANC >/= 1,500/mm3
platelet count >/=100,000/mm3
HgB ≥ 9 g/dL
Creatinine ≤ 1.5x ULN or creatinine clearance (measured via 24-hour urine collection) ≥40 mL/minute (that is, if serum creatinine is >1.5 times the ULN, a 24-hour urine collection to calculate creatinine clearance must be performed).
Total Serum Bilirubin ≤ 1.5 x ULN (Patients with known Gilbert Syndrome, a total bilirubin ≤ 3.0 x ULN, with direct bilirubin ≤ 1.5 x ULN)
SGOT, SGPT ≤ 3 X ULN if no liver metastasis present
SGOT, SGPT ≤ 5 X ULN if liver metastasis present
Females of childbearing potential must not be breast feeding and must have a negative serum or urine pregnancy test within 7 days of starting of treatment. The patient must agree to use adequate contraception for a minimum of two weeks prior to receiving study medication until 3 months after discontinuation of the study medication. Acceptable methods of contraception include total and true sexual abstinence, hormonal contraceptives that are not prone to drug-drug interactions (IUS Levonorgestrel Intra Uterine System (Mirena), Medroxyprogesterone injections (Depo-Provera)), copper-banded intra-uterine devices, and vasectomized partner. All hormonal methods of contraception should be used in combination with the use of a condom by their sexual male partner. Females of childbearing potential are defined as those who are not surgically sterile (i.e., bilateral tubal ligation, bilateral oophorectomy, or complete hysterectomy) or postmenopausal (defined as 12 months with no menses without an alternative medical cause). Women will be considered post-menopausal if they have been amenorrheic for the past 12 months without an alternative medical cause. The following age-specific requirements must also apply: Women < 50 years old: they would be considered post-menopausal if they have been amenorrheic for the past 12 months or more following cessation of exogenous hormonal treatments. The levels of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) must also be in the post-menopausal range (as per the institution). Women ≥ 50 years old: they would be considered post-menopausal if they have been amenorrheic for the past 12 months or more following cessation of all exogenous hormonal treatments, or have had radiation-induced oophorectomy with the last menses > 1 year ago, or have had chemotherapy-induced menopause with >1 year interval since last menses, or have had surgical sterilization by either bilateral oophorectomy or hysterectomy.
Non-sterilized males who are sexually active with a female partner of childbearing potential must use adequate contraception for the duration of the study and 3 months after the last dose of study medication. Adequate contraception methods include: birth control pills (e.g. combined oral contraceptive pill), barrier protection (e.g. condom plus spermicide, cervical/vault cap or intrauterine device), and abstinence. Patients should not father a child for 6 months after completion of the study medication. Patients should refrain from donating sperm from the start of dosing until 6 months after discontinuing the study medication. If male patients wish to father children they should be advised to arrange for freezing of sperm samples prior to the start of the study medication.
Participants of childbearing potential who are sexually active and their partners must agree to abstain from heterosexual activity or to use 2 forms of effective methods of contraception. Non-sterilized males who are sexually active with a female partner of childbearing potential must use adequate contraception for the duration of the study and for 3 months after the last dose of study treatment. Patients should not father a child during the study or for 6 months after completion of study treatment. Patients should refrain from donating sperm from the start of dosing until 6 months after discontinuing the study treatment. Two contraception methods can be comprised of two barrier methods, or a barrier method plus a hormonal method. See below for options:
Acceptable non-hormonal birth control methods:
Total sexual abstinence ie, refrain from any form of sexual intercourse in line with the patients' usual and/or preferred lifestyle. Abstinence must be for the total duration as described above. Periodic abstinence (eg, calendar ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.
Vasectomised sexual partner PLUS male condom. With participant assurance that partner received post-vasectomy confirmation of azoospermia.
Tubal occlusion PLUS male condom
Intrauterine Device PLUS male condom. Provided coils are copper-banded.
Acceptable hormonal methods:
Etonogestrel implants (eg, Implanon®, Norplant®) PLUS male condom
Normal and low dose combined oral pills PLUS male condom
Hormonal shot or injection (eg, Depo-Provera) PLUS male condom

Any of the following cardiac criteria:
Mean resting corrected QT interval (QTc using Fridericia's formula) > 470 msec, except in patients with existing bundle block, which artificially prolongs QTc.
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, PR interval >250msec
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.
The patient has experienced any arterial thromboembolic events, including but not limited to myocardial infarction, transient ischemic attack, cerebrovascular accident, or unstable angina, within 6 months prior to first dose of protocol therapy.
