A Phase II Trial of Durvalumab and Ablative Radiation in Extensive-Stage Small Cell Lung Cancer (DARES)

This this study is for individuals who have treatment-naïve extensive-stage small cell lung cancer (small cell lung cancer that wont respond to treatment). Doctors leading this study hope to learn if combining durvalumab, carboplatin and etoposide with hyofractionated ablative radiation therapy (radiation focused on certain parts of the body) will help treat your cancer and improve how long you can live with extensive-stage small cell cancer without it getting worse (progression-free survival). Your participation in this research will last about 48 months. Durvalumab along with chemotherapy has been approved by the Food and Drug Administration (FDA) for the treatment of small cell lung cancer along with chemotherapy. This study is testing the addition of radiation to durvalumab and chemotherapy.

Tumors larger than 65 cc can be partially treated.

         12. Female subject of childbearing potential should have a negative urine or serum pregnancy within 24 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.

         13. Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication. Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year.

         14. Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy.

        Exclusion Criteria:

        Patients should not enter the study if any of the following exclusion criteria are fulfilled:

         1. Participation in another clinical study with an investigational product during the last 2 weeks.

         2. 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

         3. Any unresolved toxicity NCI CTCAE Grade ≥2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria:

             1. Patients with Grade ≥2 neuropathy will be evaluated on a case-by-case basis after consultation with the Study Physician.

             2. Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the Study Physician.

         4. Any concurrent chemotherapy, investigational product (IP), biologic, or hormonal therapy for cancer treatment, outside of those specified as part of this clinical trial. Concurrent use of hormonal therapy for non-cancer-related conditions (e.g., hormone replacement therapy) is acceptable.

         5. 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

         6. Major surgical procedure (as defined by the Investigator) within 28 days prior to the first dose of IP. Note: Local surgery of isolated lesions for palliative intent is acceptable.

         7. History of allogenic organ transplantation.

         8. Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease [e.g., colitis or Crohn's disease], diverticulitis [with the exception of diverticulosis], systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome [granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc]). The following are exceptions to this criterion:

             1. Patients with vitiligo or alopecia

             2. Patients with hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement

             3. Any chronic skin condition that does not require systemic therapy

             4. Patients without active disease in the last 5 years may be included but only after consultation with the study physician

             5. Patients with celiac disease controlled by diet alone

         9. Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the patient to give written informed consent

         10. History of another primary malignancy except for

             1. Malignancy treated with curative intent and with no known active disease ≥5 years before the first dose of IP and of low potential risk for recurrence

         13. All patients at screening should have an MRI (preferred) or CT each preferably with IV contrast of the brain prior to study entry. Patients whose brain metastases have been treated may participate provided they show radiographic stability (defined as 2 brain images, both of which are obtained after treatment to the brain metastases. These imaging scans should both be obtained at least two weeks apart and show no evidence of intracranial progression). In addition, any neurologic symptoms that developed either as a result of the brain metastases or their treatment must have resolved or be stable either, without the use of steroids, or are stable on a steroid dose of ≤10mg/day of prednisone or its equivalent for at least 14 days prior to the start of treatment.

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 hepatitis C (HCV) ribonucleic acid (RNA).
