Overview

Study Title

A Phase II Study of Talimogene Laherparepvec (T-VEC) in the Treatment of Locally Advanced Cutaneous Angiosarcoma

Summary

Objective

Primary: To evaluate the efficacy of T-VEC as treatment for relapsed/refractory cutaneous angiosarcoma. Secondary: To establish duration of response among treated patients - To measure the rate of progression-free survival among treated patients - To measure the pathologic complete response (pCR) rate for lesions that have complete clinical regression following study treatment - To monitor adverse events following administration of T-VEC injections - To measure the rate of patients requiring surgical resection of T-VEC treated lesions - To measure the degree of immune infiltration in surgically resected T-VEC treated tumors

Inclusion Criteria

  • Participants must have histologically confirmed CA without visceral or CNS metastases, with resection deemed of no benefit by technical or oncologic principles, and have progressed on at least one line of systemic therapy
  • Participants must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded by digital photography) as >6 mm with calipers or a ruler.
  • Eastern Cooperative Oncology Group performance status 0-1 (Karnofsky >70%).
  • Participants must have normal organ and marrow function as defined per protocol

  • Exclusion Criteria

  • Participants with a second active malignancy, exceptions are localized non-melanoma skin cancers or in situ carcinoma
  • Participants receiving any other investigational agents
  • Participants with tumor(s) in direct contact or encasing a major blood vessel, those with ulceration and/or fungation onto the skin surface, and those with history of re-irradiation or prior lymph node neck dissection to a field involving the carotid arteries
  • 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 defined in protocol
  • receiving systemic immunosuppressive therapy (> 2 weeks) including oral steroid doses > 10 mg/day of prednisone or equivalent within 7 days prior to enrollment.
  • Active herpetic skin lesions or prior complications of HSV-1 infection (e.g., herpetic keratitis or encephalitis).
  • Requires intermittent or chronic systemic (intravenous or oral) treatment with an antiherpetic drug (e.g., acyclovir), other than intermittent topical use.
  • Previous treatment with talimogene laherparepvec or any other oncolytic virus.
  • Prior therapy with tumor vaccine.
  • Received live vaccine within 28 days prior to enrollment.
  • Prior immunosuppressive, chemotherapy, radiotherapy (in which the field encompassed a planned injection site), biological cancer therapy, or major surgery within 28 days prior to enrollment or has not recovered to CTCAE grade 1 or better from adverse event due to cancer therapy administered more than 28 days prior to enrollment.
  • Prior radiotherapy in which the field does not overlap the injection sites or non-immunosuppressive targeted therapy within 14 days prior to enrollment or has not recovered to CTCAE grade 1 or better from adverse event due to cancer therapy administered more than 14 days prior to enrollment
  • Currently receiving treatment with another investigational device or drug study, or >Known to have acute or chronic active hepatitis B infection, hepatitis C infection, or human immunodeficiency virus (HIV) infection.
  • History of other malignancy within the past 5 years with the following exceptions: adequately treated non melanoma skin cancer, cervical carcinoma in situ, breast ductal carcinoma in situ, or prostatic intraepithelial neoplasia without evidence of disease at the time of enrollment
  • Participant has known sensitivity to talimogene laherparepvec or any of its components to be administered during dosing.
  • Female participant is pregnant or breast-feeding, or planning to become pregnant during study treatment and through 3 months after the last dose of talimogene laherparepvec.
  • Female participant of childbearing potential who is unwilling to use acceptable method(s) of effective contraception during study treatment and through 3 months after the last dose of talimogene laherparepvec.
  • Sexually active participants and their partners unwilling to use male or female latex condom to avoid potential viral transmission during sexual contact while on treatment and within 30 days after treatment with talimogene laherparepvec.
  • Participants who are unwilling to minimize exposure with his/her blood or other body fluids to individuals who are at higher risks for HSV-1 induced complications such as immunosuppressed individuals, individuals known to have HIV infection, pregnant women, or infants under the age of 3 months, during talimogene laherparepvec treatment and through 30 days after the last dose of talimogene laherparepvec.
