ClinConnect Summary

The purpose of this study is to assess the effect of Talimogene laherparepvec (TVEC) in patients diagnosed with lower risk cSCC in need of alternative therapeutic approaches.

Immune recognition and cytotoxic responses play an important role in the pathogenesis and progression of cutaneous squamous cell carcinoma (cSCC). TVEC is an HSV-1 oncolytic immunological agent FDA approved for the local treatment of unresectable recurrent melanoma. It is proposed that T-VEC directly destroys cancer cells and induces production of GM-CSF to enhance systemic antitumor immune priming. This proposed mech...

• • 3. Have at least one \>0.5 cm to \<5.0 cm, histologically confirmed low risk cutaneous SCC (including kerathoacanthomas)

• • Clinically consistent with primary tumors.
• • Lesion considered unresectable (as defined in Section 1.2)
• • Recurrent lesions will be considered eligible if additional inclusion criteria are met.
• • No immunosuppression
• • Not a site of previous radiation therapy or chronic significant inflammation
• • Fast growing lesions (doubling in size over a 4 week period of time) will be included if they are clinically suggestive of cSCC of the keratoacanthoma type.

• • Depth less than 2 mm (for non KA type cSCC )
• • No perineural or vascular involvement in preliminary biopsy.
• • 4. Partial biopsy of squamous cell skin cancer identified as a target lesion(s) to determine the histological differentiation of the tumor or other adverse histological features
• • 5. In patients with multiple lesions, up to 3 lesions in a similar anatomical site, (trunk, limbs etc) that is at least 10 cm apart can be selected.
• • 6. Maximum of 5 lesions per patient can be selected for treatment
• 7. Adequate organ function determined within 28 days prior to enrollment, defined as follows:
• 8. Hematology:
• • Absolute neutrophil count ≥ 1500/mm3 (1.5x109/L)
• • Platelet count ≥ 75,000/mm3 (7.5x109/L)
• • Hemoglobin ≥ 8 g/dL (without need for hematopoietic growth factor or transfusion support)
• • 9. Renal
• • • Serum creatinine ≤ 1.5 x upper limit of normal (ULN), OR 24-hour creatinine clearance ≥ 60 mL/min for subject with creatinine levels \> 1.5 x ULN. (Note: Creatinine clearance need not be determined if the baseline serum creatinine is within normal limits. Creatinine clearance should be determined per institutional standard)
• • 10. Hepatic
• • Serum bilirubin ≤ 1.5 x ULN
• • Aspartate aminotransferase (AST) ≤ 2.5 x ULN 23 \| Page Version 6-26-2018
• • Alanine aminotransferase (ALT) ≤ 2.5 x ULN
• • 11. Coagulation
• • International normalization ratio (INR) or prothrombin time (PT) ≤ 1.5 x ULN, unless the subject is receiving anticoagulant therapy, in which case PT and partial thromboplastin time (PTT)/ activated PTT (aPTT) must be within therapeutic range of intended use of anticoagulants.
• • PTT or aPTT ≤ 1.5 x ULN unless the subject is receiving anticoagulant therapy as long as PT and PTT/aPTT is within therapeutic range of intended use of anticoagulants.
• • 12. Female subject of childbearing potential should have a negative urine or serum pregnancy test within 72 hours prior to enrollment. If urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
• Exclusion Criteria:
• • 1. Any patient with diagnosis of invasive cancer in the last 3 years with the exception of stage I and II melanoma, cutaneous BCC and SCCs will be excluded.
• • 2. Subjects on acitretin, capecitabine, topical chemotherapies or treatments.

History or evidence of symptomatic autoimmune disease (eg, pneumonitis, glomerulonephritis, vasculitis, or other), or history of active autoimmune disease that has required systemic treatment (ie, use of corticosteroids, immunosuppressive drugs or biological agents used for treatment of autoimmune diseases) in past 2 months prior to enrollment. Replacement therapy (eg, thyroxine for hypothyroidism, insulin for diabetes or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment for autoimmune disease.
• 4. Evidence of clinically significant immunosuppression such as the following:
• • Primary immunodeficiency state such as Severe Combined Immuno deficiency Disease
• • Acquired immunodeficiency syndrome
• • Concurrent opportunistic infection
• • Receiving systemic immunosuppressive therapy (\> 2 weeks) including oral steroid doses \> 10 mg/day of prednisone or equivalent within 2 months prior to enrollment.
• • 5. Active herpetic skin lesions or prior complications of herpetic infection (e.g., herpetic keratitis or encephalitis).
• • 6. Requires intermittent or chronic systemic (intravenous or oral) treatment with an antiherpetic drug (e.g., acyclovir), other than intermittent topical use.
• • 7. Previous treatment with talimogene laherparepvec or any other oncolytic virus

• • 10. Currently receiving treatment with another investigational device or drug study, or \< 28 days since ending treatment with another investigational device or drug study(s)
• • 11. Other investigational procedures while participating in this study are excluded.
• • 12. Known to have acute or chronic active hepatitis B infection
• • 13. Known to have acute or chronic active hepatitis C infection
