Lung Cancer Clinical Trial
Personalized Neoantigen Vaccine in Combination With Durvalumab (MEDI4736) in Extensive Stage Small Cell Lung Cancer

Women < 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy).

Prior treatment with a PD-1 or PD-L1 inhibitor (including durvalumab).
A history of other primary malignancy except for:
Malignancy treated with curative intent and with no know active disease â‰¥ 5 years before the first dose of study drug and of low potential risk for recurrence
Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease
Adequately treated carcinoma in situ without evidence of disease
Currently receiving any other investigational agents.
Concurrent enrollment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study.
Prior randomization or treatment in a previous durvalumab clinical study regardless of treatment arm assignment.
Any unresolved toxicity NCI CTCAE grade â‰¥ 2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria.
Patients with grade â‰¥ 2 neuropathy will be evaluated on a case-by-case basis after consultation with the PI.
Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the PI.
Radiotherapy treatment to more than 30% of the bone marrow or with a wide field of radiation within 4 weeks of the first dose of study drug.
Major surgical procedure (as defined by the PI) within 28 days prior to the first dose of study drug. Note: local surgery of isolated lesions for palliative intent is acceptable.
History of allogenic organ transplantation.
History of leptomeningeal carcinomatosis.
Any known history of brain metastases. Patients with known brain metastases must be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
A history of allergic reactions attributed to compounds of similar chemical or biologic composition to durvalumab or other agents used in the study.
Known allergy, or history of serious adverse reaction to vaccines such as anaphylaxis, hives, or respiratory difficulty.
Uncontrolled intercurrent illness including, but not limited to:
uncontrolled ongoing or active infection
a history of myocarditis or congestive heart failure (as defined by New York Heart Association Functional Classification III or IV)
myocardial infarction 6 months prior to study entry
unstable angina pectoris
serious uncontrolled cardiac arrhythmia
interstitial lung disease (ILD) or a history of ILD/pneumonitis requiring treatment with systemic steriods
serious chronic gastrointestinal conditions associated with diarrhea
psychiatric illness or social situations that would limit compliance with study requirements, substantially increase the risk of incurring AEs, or compromise the ability of the patient to give written informed consent.
Current or prior use of immunosuppressive medication within 14 days before the first dose of durvalumab. The following are exceptions to this criterion:
Intranasal, inhaled, topical steroids, or local steroid injections (e.g. intra-articular injection)
Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or its equivalent
Steroids as premedication for hypersensitivity reactions (e.g. CT scan premedication)
Receipt of live attenuated vaccine within 30 days prior to the first dose of study drug. Note: patients, if enrolled, should not receive live vaccine whilst receiving study drug and up to 30 days after the last dose of study drug.
History of syncopal or vasovagal episode as determined by medical record and history in the 12 month period prior to enrollment
Less than 2 acceptable potential injection sites for IM injection and electroporation considering the left and right medial deltoid, and anterolateral quadriceps muscles. A site for injection and electroporation is not acceptable if there is inadequate muscle mass to support at least a 19 mm /0.75 inch injection depth or a skin pinch thickness measurement of >50 mm as assessed using the provided caliper). Eligible injection sites must also have intact lymphoid drainage and be free from tattoos, hypertrophic skin patches, keloids or other skin conditions which could interfere with the administration procedure or subsequent assessment of local reactogenicity. Note: In order to ensure adequate muscle mass for administrations for participants with a weight <65 kg, potentially eligible administration sites are confined to the outer aspect of the upper thigh (left or right vastus lateralis muscle). The left and right medial deltoid are not eligible administration sites for those participants.
Is an individual in whom the ability to observe possible local site reactions at >2 eligible injection sites (left and right medial deltoid or left and right vastus lateralis muscles) is, in the opinion of the investigator, unacceptably obscured due to a physical condition.
Has a metal implant or implantable device within the area of the electroporation injection site at >2 of the eligible injection sites.
Contraindication to intramuscular injections and/or blood draws.
Any chronic or active neurologic disorder, including seizures and epilepsy, excluding a single febrile seizure as a child.
Current use of any non-removable electronic stimulation device, such as cardiac demand pacemakers, automatic implantable cardiac defibrillator, nerve stimulators, or deep brain stimulators.

The following are exceptions to this criterion:
Patients with vitiligo or alopecia
Patients with hypothyroidism (e.g. following Hashimoto syndrome) stable on hormone replacement
Any chronic skin condition that does not require systemic therapy
Patients without active disease in the last 5 years may be included but only after consultation with the study physician
Patients with celiac disease controlled by diet alone
Pregnant and/or breastfeeding. Women of childbearing potential must have a negative pregnancy test within 14 days of study entry.
History of primary active immunodeficiency.
Active infection including tuberculosis (clinical evaluation that includes clinical history, physical examination and radiographic findings, and TB testing in line with local practice), hepatitis B (known positive HBV surface antigen (HBsAg) result), hepatitis C, or human immunodeficiency virus (positive HIV 1/2 antibodies). Patients with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody [anti-HBc] and absence of HBsAg) are eligible. Patients positive for hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV RNA.
