A Phase II Trial of AZD1775 plus Carboplatin-Paclitaxel in Squamous Cell Lung Cancer
This phase II trial studies how WEE1 Inhibitor AZD1775, carboplatin, and paclitaxel work in treating patients with squamous cell lung cancer that has spread to other places in the body (metastatic) and usually cannot be cured or controlled with treatment (advanced), or has come back (recurrent). WEE1 inhibitor AZD1775 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving WEE1 inhibitor AZD1775 together with carboplatin and paclitaxel may be an effective treatment for squamous cell lung cancer.

- Eastern Cooperative Oncology Group (ECOG) performance status of 0/1
- Prior chemotherapy in the adjuvant/neoadjuvant/consolidation setting is allowed
- Any prior palliative radiation must have been completed at least 7 days prior to the start of studies drugs and patients must have recovered from any acute adverse effects prior to the start of the study treatment

- Have archival tissue available or undergo a fresh biopsy where clinically feasible after discussion with the sponsor
- No reproductive toxicology nor teratogenic studies have been conducted with AZD1775 to date, and it is unknown whether the drug is excreted in human milk; therefore, women of childbearing potential and men should agree to use adequate contraception prior to study entry and for the duration of study participation and women who are breast feeding are excluded from the study. Both women and men should be fully informed of the lack of reproductive toxicity testing, and women must have a negative pregnancy test prior to enrollment
- Female patients are considered to be of childbearing potential unless: * They are post-menopausal (defined as older than 50 years and amenorrheic for at least 12 months following cessation of all exogenous hormonal treatments) * There is documentation of irreversible surgical sterilization by hysterectomy, bilateral oophorectomy or bilateral salpingectomy (but not tubal ligation), or * They are 50 years or younger but have been amenorrheic for at least 12 months following the cessation of exogenous hormonal treatments, and have serum follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels in the postmenopausal range for the institution ** Female patients who are of childbearing potential must agree to use adequate contraceptive measures (as defined below) for the duration of study participation, and for 90 days after the final dose of study drug; cessation of birth control after this point should be discussed with a responsible physician; they also may not be breast feeding and must have a negative serum or urine pregnancy test within 72 hours prior to start of study treatment ** Male patients who are sexually active with a female partner of childbearing potential must be either surgically sterilized or agree to use barrier contraception (i.e., condoms) for the duration of study participation, and for 90 days after the final dose of study drug; cessation of birth control after this point should be discussed with a responsible physician
- Female patients who are of child-bearing potential (as defined above) should use enhanced methods of contraception from the time of screening until 90 days after the final dose of study drug; cessation of birth control after this point should be discussed with a responsible physician; acceptable methods of contraception include true abstinence in line with the preferred and usual lifestyle choice of the subject, tubal ligation, vasectomized partner, and methods listed in the table below; all methods of contraception (with the exception of total abstinence) should be used in combination with the use of a condom by their male sexual partner for intercourse; periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
- Effective methods of contraception: * Barrier methods ** Cap plus spermicide ** Sponge plus spermicide ** Diaphragm plus spermicide * Intrauterine device methods ** Copper T ** Levonorgestrel-releasing intrauterine system (e.g., Mirena); this is also considered a hormonal method * Hormonal methods ** Any registered and marketed contraceptive agent that contains an estrogen and/or a progestational agent (including oral, subcutaneous, intrauterine, or intramuscular agents) such as *** Implants *** Hormone shot or injection *** Combined pill *** Minipill *** Patch
- Male patients should be asked to avoid unprotected sex with all sexual partners but use condoms plus spermicide during the study, and for a washout period of 90 days after the last dose of study drug; where a sexual partner of a male participant is a woman of child-bearing potential, patients should avoid procreation for 90 days after completion of study drug treatment; patients should refrain from donating sperm from the start of dosing until 90 days after discontinuing study treatment; if male patients wish to father children they should be advised to arrange for freezing of sperm samples prior to the start of study treatment
- Progressive, symptomatic untreated brain metastases
- Pregnancy or breast feeding
- A serious uncontrolled medical disorder or active infection that in the investigator’s opinion would impair the patient’s ability to receive study treatment
- Prior use of platinum or paclitaxel for stage IV non-small cell lung cancer (NSCLC) or concurrent use of other anticancer approved or investigational agents
- Use of anti-cancer treatment drug =< 21 days or 5 half-lives (whichever is shorter) prior to the first dose of AZD1775; for drugs for which 5 half-lives is =< 21 days, a minimum of 10 days between termination of the prior treatment and administration of AZD1775 treatment is required
- Major surgical procedures =< 28 days of beginning study treatment, or minor surgical procedures =< 7 days; no waiting period required following port-a-cath or other central venous access placement

Trial Objectives and Outline
I. Determine the progression-free survival of carboplatin-paclitaxel plus AZD1775 (WEE1 Inhibitor AZD1775) in patients with advanced/metastatic squamous cell lung cancer (SQCLC).
I. Estimate time-to-event variables, such as overall survival time, duration of overall response, and duration of stable disease.
II. Estimate the disease control rates (complete response, partial response, and stable disease).
I. Assess pharmacodynamic endpoints in tumor tissue.
II. Determine the frequency of tissue biomarkers (including WEE1, PAX transcription activation domain-interacting protein [PAXIP]1, phosphorylated [phospho]-Y15-cyclin dependent kinase [CDK]1).
III. Examine potential resistance mechanisms in the tumors of clinical non-responders.
IV. Compare tissue biomarkers with clinical covariates and outcomes.
Patients receive WEE1 inhibitor AZD1775 orally (PO) once daily (QD) on day 1 and twice daily (BID) on days 2-3 for a total of 5 doses, carboplatin intravenously (IV) on day 1, and paclitaxel IV on day 1. Treatment repeats every 21 days for 4-6 courses at the discretion of the treating physician. Patients continue to maintenance treatment with WEE1 inhibitor AZD1775 PO QD on day 1 and BID on days 2-3. Courses for WEE1 inhibitor AZD1775 repeat every 21 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 30 days and then every 3 months.
