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 below:
- 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 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 such as the following:
- Primary immunodeficiency state such as Severe Combined Immunodeficiency Disease.
- concurrent opportunistic infection.
- 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 <
28 days since ending treatment with another investigational device or drug study(s).
- Other investigational procedures while participating in this study are excluded.
- 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 subject 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 subject 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 subjects 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.
