Clinical Trial Summary

This study will investigate whether the use of talimogene laherparepvec (T-VEC) in combination with BRAF/MEK inhibitor will result in durable regional and distant recurrence free survival in the neoadjuvant setting for treatment of advanced nodal BRAF mutant melanoma.

Description:

This is a prospective, non-randomized, open-label, single-center interventional study looking at the response rate when using talimogene laherparepvec (T-VEC) in combination with BRAF/MEK inhibitor in neoadjuvant setting for treatment of advanced nodal BRAF mutant melanoma. For this pilot study, a sample size of 20 participants, over 18 years of age will be included.

Eligibility

Inclusion

• Age = 18

• Malignant melanoma Stage IIIb-IVM1a patients.

• Primary or recurrent disease.

• Cutaneous primary melanoma or unknown primary.

• Measurable disease as evidenced by:

• At least one lesion measuring greater than or equal to 10 mm on CT, ultrasound, or physical exam

• A conglomerate of superficial lesions measuring which in aggregate have a total diameter of 10 mm

• Injectable disease

• Palpable regional metastasis at the time of initial presentation or with regional recurrence

• Tumor(s) with BRAF mutation

• ECOG 0,1,2

• Life expectancy > 2 years in the opinion of the investigator

• Able to provide written informed consent

• Adequate organ function based on most recent labs (according to investigator discretion), defined as follows:

• Hematological: 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)

• 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 = 1.5 x ULN. . Creatinine clearance should be determined per institutional standard).

• Hepatic: Serum bilirubin = 1.5 x ULN OR direct bilirubin = ULN for a subject with total bilirubin level > 1.5 x ULN; Aspartate aminotransferase (AST) = 2.5 x ULN OR = 5 x ULN, if liver metastases present and injection does not involve a visceral lesion; Alanine aminotransferase (ALT) = 2.5 x ULN OR = 5 x ULN, if liver metastases present and injection does not involve a visceral lesion

• 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.

• Female subjects 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

• BRAF wild type tumor

• M1b and M1c disease

The exception does not include carcinomatosus meningitis which is excluded regardless of clinical stability.

• History or evidence of active autoimmune disease that requires systemic treatment (ie, with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg, thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.

• Evidence of clinically significant immunosuppression such as the following:

Adjuvant hormonal therapy is allowed if appropriate for planned study.
