Clinical Trial Summary

In this study, patients with small cell or non-small cell lung cancer will receive ADI-PEG 20, gemcitabine, and docetaxel after demonstrated progression on frontline therapy. In phase I of the study, up to 6 dose levels will be tested to find the recommended phase II dose (RP2D), after which patients enrolling to phase II will be treated at that dose level to assess efficacy. Although safety and tolerability has been previously determined in the sarcoma population, dose de-escalations of the chemotherapies in that patient population were required. Therefore, a phase I portion will be incorporated to determine the RP2D of the triplet in this population.

• Creatinine clearance > 60 mL/min by MDRD or by 24 hour urine

• Serum uric acid = 8 mg/dL (with or without medication control)

• The effects of ADI-PEG 20 on the developing human fetus are unknown. For this reason and because chemotherapeutics are known to be teratogenic, women of childbearing potential 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 one month after completion of study treatment. Should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of the study, and for one month after completion of study treatment.

• Ability to understand and willingness to sign an IRB approved written informed consent document.

Exclusion Criteria:

• A history of other malignancy with the exception of:

• Malignancies for which all treatment was completed at least 2 years before registration and the patient has no evidence of disease

• Basal cell or squamous cell carcinoma of the skin which was treated with local resection only

• Carcinoma in situ of the cervix

• Other tumors discussed with the study PI

• Currently receiving any other investigational agents.

• Prior treatment with ADI-PEG 20 or gemcitabine (prior docetaxel is allowed).

• Presence of untreated or unstable brain metastases. Patients with treated/stable brain metastases, defined as patients who have received prior therapy for their brain metastases and whose CNS disease is radiographically stable at study entry, are eligible.

• A history of allergic reactions attributed to compounds of similar chemical or biologic composition to ADI-PEG 20, gemcitabine, pegylated compounds, or other agents used in the study.

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, or cardiac arrhythmia.

• History of seizure disorder not related to underlying cancer.

• Grade 2 or higher neuropathy

• Pregnant and/or breastfeeding. Women of childbearing potential must have a negative pregnancy test within 14 days of study entry.

• Patients with known active Hepatitis B or C or HIV.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Recommended phase II dose (Phase I only)	-The maximum tolerated dose (MTD) is defined as the dose level immediately below the dose level at which 2 patients of a cohort (of 2 to 6 patients) experience dose-limiting toxicity during the first 4 weeks of treatment. Dose escalations will proceed until the MTD has been reached or until Dose Level 3, and this dose level will then be defined as the Recommended Phase 2 Dose (RP2D).	Through the first 4 weeks of treatment for all Phase I enrolled participants (estimated to be 12 months and 4 weeks)
Primary	Treatment-related serious adverse event (SAE) rate (Phase I only)	-SAE: an adverse event or suspected adverse reaction is considered "serious" if, in the view of the investigator, it results in any of the following outcomes: Death; A life-threatening adverse event; Inpatient hospitalization or prolongation of existing hospitalization; A persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions; A congenital anomaly/birth defect; Any other important medical event that does not fit the criteria above but, based upon appropriate medical judgment, may jeopardize the subject and may require medical or surgical intervention to prevent one of the outcomes listed above	From start of treatment through 30 days after completion of treatment (estimated to be 106 weeks)
Primary	Objective response rate (ORR) (Phase II only - compared between non-small cell lung and small cell lung)	ORR = percentage of participants with complete response + partial response.; Complete response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Disappearance of all non-target lesions and normalization of tumor marker level.; Partial response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.	Through completion of treatment (estimated to be 102 weeks)
Secondary	Progression-free survival (PFS) (Phase II only - compared between non-small cell lung and small cell lung)	PFS is defined as the time from date of treatment initiation to disease progression or death from any cause, whichever occurs first. The patients alive, without progression, are censored at the last follow-up.; Progressive disease (PD): At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. Appearance of one or more new lesions and/or unequivocal progression of existing non-target lesions. Unequivocal progression should not normally trump target lesion status. It must be representative of overall disease status change, not a single lesion increase.	Through completion of follow-up (estimated to be up to 362 weeks)
Secondary	Overall survival (OS) (Phase II only - compared between non-small cell lung and small cell lung)	OS is defined as the time from the date of treatment initiation to the date of death, censored at the last follow-up otherwise.	Through completion of follow-up (estimated to be up to 362 weeks)
Secondary	Clinical benefit rate (CBR) (Phase II only - compared between non-small cell lung and small cell lung)	CBR = the percentage of participants who have experienced complete response + partial response + stable disease.; Complete response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Disappearance of all non-target lesions and normalization of tumor marker level.; Partial response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.; Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study. Persistence of one or more non-target lesion(s) and/or maintenance of tumor marker level above the normal limits.	Through completion of treatment (estimated to be 102 weeks)
Secondary	Cancer-related mortality rate (Phase II only - compared between non-small cell lung and small cell lung)		Through completion of follow-up (estimated to be up to 362 weeks)
