Lung Cancer Clinical Trial

Adaptive SBRT Plus Chemoimmunotherapy for ES-SCLC

Summary

This is trial studying the safety of adaptive stereotactic body radiotherapy (SBRT) combined with durvalumab immunotherapy, platinum chemotherapy, and etoposide chemotherapy in platinum refractory extensive stage small cell lung cancer (SCLC).

Full Description

This is a phase Ib, open-label, single-arm study in newly diagnosed patients with extensive stage SCLC, to test the safety of the adaptive addition of SBRT to combination therapy with durvalumab, platinum, and etoposide. Approximately 50 patients with ES-SCLC will be enrolled in this study in order to identify 20 patients with platinum refractory disease who do not show evidence of early response to chemoimmunotherapy. Eligible patients will complete 2 cycles of study treatment with durvalumab, platinum (cisplatin or carboplatin per investigator choice), and etoposide. Patients will then undergo standard of care restaging imaging. Those patients who have a partial or complete response will continue with combination systemic therapy, without additional intervention.

In patients with less than a partial response (stable disease or progressive disease), SBRT will be given prior to cycle 3 of systemic therapy. The radiotherapy will be given in 5 fractions of 6 Gy to the primary tumor site. See study schema. Patients who undergo SBRT will resume systemic therapy within 2 weeks of completing SBRT and the interval between cycle 2 and cycle 3 should not exceed 6 weeks. Subsequent restaging imaging will continue as per standard of care. All patients will continue maintenance therapy with durvalumab until confirmed progressive disease.

Eligibility Criteria

Inclusion Criteria:

Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol. Written informed consent and any locally required authorization (eg, Health Insurance Portability and Accountability Act in the US, European Union [EU] Data Privacy Directive in the EU) obtained from the patient/legal representative prior to performing any protocol-related procedures, including screening evaluations.
Age > 18 years at time of study entry
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
Body weight >30 kg

Adequate normal organ and marrow function as defined below:

Hemoglobin ≥10.0 g/dL
Absolute neutrophil count (ANC) ≥1.5 × 109 /L
Platelet count ≥100 × 109/L
Serum bilirubin ≤1.5 x institutional upper limit of normal (ULN). This will not apply to patients with confirmed Gilbert's syndrome (persistent or recurrent hyperbilirubinemia that is predominantly unconjugated in the absence of hemolysis or hepatic pathology), who will be allowed only in consultation with their physician
AST (SGOT)/ALT (SGPT) ≤2.5 x institutional upper limit of normal unless liver metastases are present, in which case it must be ≤5x ULN
Creatinine WNL or if >ULN, then measured creatinine clearance (CL) >50 mL/min or calculated creatinine CL>50 mL/min by the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-hour urine collection for determination of creatinine clearance:

Males:

Creatinine CL (mL/min) = Weight (kg) x (140 - Age) 72 x serum creatinine (mg/dL)

Females:

Creatinine CL (mL/min) = Weight (kg) x (140 - Age) x 0.85 72 x serum creatinine (mg/dL)

Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up.
Confirmed histologic or cytologic diagnosis of small cell lung cancer
No prior treatment for ES-SCLC (patients who received not more than one cycle of chemotherapy ± durvalumab as SOC prior to enrolment may be allowed on study at the discretion of the study sponsor)
Extensive stage disease at diagnosis
Measurable disease per Recist 1.1
Female Patients must either be of non-reproductive potential (i.e., post-menopausal by history: ≥50 years old and no menses for 1 year without an alternative medical cause; OR history of hysterectomy, OR history of bilateral tubal ligation, OR history of bilateral oophorectomy) or must have a negative serum pregnancy test upon study entry.

Exclusion Criteria:

Participation in another clinical study with an investigational product during the last 4 weeks prior to first dose of IP
Concurrent enrolment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study

Any unresolved toxicity National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Grade ≥2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria

Patients with Grade ≥2 neuropathy will be evaluated on a case-by-case basis.
Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the Study PI/Sponsor
Major surgical procedure within 28 days prior to the first dose of IP. Note: Local surgery of isolated lesions for palliative intent is acceptable.
History of allogenic organ transplantation.

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:

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
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

History of another primary malignancy except for

Malignancy treated with curative intent and with no known active disease ≥2 years before the first dose of IP 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

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.
