Ph I/II Trial of Systemic VSV-IFNβ-NIS in Combination With Checkpoint Inhibitor Therapy in Patients With Select Solid Tumors

ClinConnect Summary

This clinical trial is investigating a new treatment approach for patients with advanced solid tumors, specifically focusing on non-small cell lung cancer (NSCLC) and neuroendocrine carcinoma (NEC). The study aims to find the best dose of a combination therapy using a virus called VSV-IFNβ-NIS and an immune checkpoint inhibitor medication called pembrolizumab. The trial consists of two parts: a safety run-in to determine the optimal dose, followed by an expansion phase to evaluate the treatment's effectiveness in patients whose cancer has not responded to previous therapies.

To participate, patients must have a confirmed diagnosis of advanced solid tumors, including specific types of NSCLC or NEC, and have experienced disease progression despite existing treatment options. They should generally be in good health, with a life expectancy of at least three months, and be willing to provide biological samples, such as a tumor biopsy. Participants will receive close monitoring to ensure their safety throughout the study. This trial is currently recruiting patients, and a total of up to 40 individuals may take part, allowing researchers to gather important information about this potential new treatment.

Eligibility criteria

• Inclusion Criteria:
• * Histologically confirmed diagnosis of:
• • Arm 1: dose level 1 and below: Advanced and/or metastatic solid tumors for which no existing options are felt to provide clinical benefit
• • Arm 2: dose level 2: Advanced and/or metastatic NSCLC OR NEC in which radiological progression has been demonstrated during therapy with a PD-1/PD-L1 immune checkpoint inhibitor, and for which no existing options are felt to provide clinical benefit.
• • Arm 3: Advanced and/or metastatic NEC in which radiological progression has been demonstrated during therapy with a PD-1/PD-L1 immune checkpoint inhibitor, and for which no existing options are felt to provide clinical benefit.
• • Arm 4: Advanced and/or metastatic NSCLC in which radiological progression has been demonstrated during therapy with a PD-1/PD-L1 immune checkpoint inhibitor, and for which no existing options are felt to provide clinical benefit.
• • Arm 5: NEC: poorly differentiated NEC (large or small cell, or not further specified) with progressive disease following at least one prior line of systemic therapy.
• • Arm 6: RCC: histologically confirmed diagnosis of advanced or metastatic RCC, including all IMDC risk categories (favorable, intermediate, and poor risk).
• • Measurable disease based on RECIST 1.1. The first 3 patients in the safety run-in phase do not need measurable disease. Part C: advanced NEC (neuroendocrine carcinoma based on histopathology according to WHO criteria. Patients with small cell carcinoma, large cell neuroendocrine carcinoma, and neuroendocrine carcinoma not otherwise specified, of any primary organ are eligible in which radiological progression has been demonstrated during therapy with a PD-(L)1 immune checkpoint inhibitor, and for which no existing options are felt to provide clinical benefit.
• • Performance status of 0 or 1 on the ECOG Performance Scale.
• • Life expectancy of \>3 months if not on active anti-cancer therapy
• • Willingness to provide biological samples required for the duration of the study including a fresh tumor biopsy sample.
• • Adequate organ function using predefined laboratory values obtained ≤14 days prior to registration.
• • Negative pregnancy test for female patients of childbearing potential
• • Absence of active CNS involvement. NOTE: Pre-enrollment imaging of asymptomatic patients not mandatory
• • Ability to provide written informed consent.
• • Willing and able to comply with scheduled visits, treatment schedule, and laboratory testing.
• Exclusion Criteria:
• • Availability of and patient acceptance of curative therapy.
• • a. For NSCLC cohort: i. Known EGFR mutations which are sensitive to available targeted inhibitor therapy (including, but not limited to, deletions in exon 19 and exon 21 \[L858R\] substitution mutations). All patients with non-squamous histology must have been tested for EGFR mutation status; use of an FDA-approved test is strongly encouraged. ii. Non-squamous histology and unknown or indeterminate EGFR status. b. Part D NSCLC cohort: Known ALK translocations which are sensitive to available targeted inhibitor therapy. If tested, use of an FDA-approved test is strongly encouraged. Patients with unknown or indeterminate ALK status may be enrolled.
• * Recent or ongoing serious infection, including:
• • 1. Any active Grade 3 or higher (per the NCI CTCAE, version 4.03) viral, bacterial, or fungal infection within 2 weeks of registration.
• • 2. Known seropositivity for or active infection by the human immunodeficiency virus (HIV).
• • 3. Acute hepatitis B or acute hepatitis C. Patients with chronic hepatitis B or hepatitis C may be enrolled provided their liver function is adequate as per section 3.17
• • 4. Known history of active TB (Bacillus tuberculosis).
• • Any serious health condition, which, in the opinion of the investigator, would place the patient at undue risk from the study, including uncontrolled hypertension and/or diabetes, clinically significant pulmonary disease (e.g., chronic obstructive pulmonary disease requiring hospitalization within 3 months) or neurological disorder (e.g., seizure disorder active within 3 months)
• * Prior therapy within the following timeframe before the planned start of study treatment as follows:
• • Chemotherapy, small molecule inhibitors, radiation, interventional radiology procedure, and/or other investigational agent: ≤3 weeks or 5 half-lives, whichever is shorter
• • Other monoclonal antibodies, antibody-drug conjugates, radioimmunoconjugates, or experimental therapies: ≤4 weeks (≤3 weeks with documented disease progression)
• • Prior palliative radiotherapy to non-CNS lesions must have been completed at least 2 weeks prior to randomization. Subjects with symptomatic tumor lesions at baseline that may require palliative radiotherapy within 4 weeks of randomization are strongly encouraged to receive palliative radiotherapy prior to randomization.
• • NSCLC patients only: prior chemotherapy or immunotherapy or a combination of chemotherapy and immunotherapy for stage IV NSCLC.
• * RCC patients:
• • i. Previously received a CTLA-4 inhibitor in the first-line setting. ii. Relapsed/progressed during adjuvant immunotherapy with a PD-(L)1 inhibitor or relapse within 12 months after completion of adjuvant immunotherapy
• • New York Heart Association classification III or IV, known symptomatic coronary artery disease, or symptoms of coronary artery disease on systems review, or known cardiac arrhythmias (atrial fibrillation or SVT) (Appendix II).
• • Any known or suspected active organ-threatening autoimmune disease, such as inflammatory bowel disease, autoimmune hepatitis, lupus, or pneumonitis, with the exception of hypothyroidism and type 1 diabetes that are controlled with treatment.
