Phase 1 Study of GRN-1201 in HLA-A*02 Subjects With Resected Melanoma

Completed · Phase 1

Conditions studied: Melanoma

In brief

This is a study of an investigational cancer vaccine called GRN-1201. Treatment with the GRN-1201 vaccine is a type of immunotherapy. The goal of immunotherapy is to stimulate the body's immune system (white blood cells) to attack cancer cells and kill them. GRN-1201 consists of 4 different peptides (small parts of proteins) that are expressed by melanoma cells. The intent of treatment with GRN-1201 is to increase your body's immune response to melanoma. To further increase your body's immune response against tumor cells, the GRN-1201 vaccine will be mixed with Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF, also known as sargramostim). GM-CSF is a man-made protein that helps stimulate the immune system and increase the response against the tumor cells. This is a phase I study which means that this will be the first time GRN-1201 is given in combination with GM-CSF to humans. It will be tested in a small number of people to evaluate its safety, find a safe dose, and identify side effects. The safety of GRN-1201 will be tested at three different doses; the GM-CSF dose will remain the same.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Males and females ≥18 years of age (at the time consent is obtained);
• Provide written informed consent for study participation, approved by the appropriate institutional review board (IRB), and be willing and able to cooperate with all aspects of the protocol;
• Resected, histologically proven, cutaneous melanoma determined to be Stage IIb, IIc, or III; according to the American Joint Commission of Cancer Staging, 7th edition
• Human leukocyte antigen (HLA)-A*02+ by serology by an ASHI accredited laboratory;
• Eastern Cooperative Oncology Group (ECOG) performance status of 0;
• Female subjects must have a negative serum human chorionic gonadotropic (hCG) test (pregnancy test not required for subjects with bilateral oophorectomy and/or hysterectomy or for those subjects who are >1 year post-menopausal); and
• All female and male subjects of reproductive potential must agree to use an effective method of contraception, as determined by the Investigator, during and for 3 months after the last dose of study drug.

You may not qualify if…

• Inadequate hematologic or biologic function as determined by the following laboratory tests:
• Hemoglobin <10 g/dL,
• Platelet count <100,000/µL,
• Leukocyte count <3000/µL,
• Lymphocyte count <1000/µL,
• Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) >2 × upper limit of normal (ULN),
• Total bilirubin >ULN: Subjects with Gilbert's syndrome are allowed if total bilirubin is <3.0 mg/dL and direct bilirubin is ≤ULN,
• Serum creatinine >ULN, or Prothrombin time (PT) or international normalized ratio (INR) >1.5 × ULN or activated partial thromboplastin time (aPTT) > 1.5 × ULN
• Greater than 3 months since melanoma resection;
• Have known fungal, bacterial, and/or viral infection, including human immunodeficiency virus (HIV) or hepatitis virus (B or C);
• Active immunosuppressive therapy associated with: Organ or allogeneic hematopoietic stem cell transplant, High-dose steroids, such as daily steroid doses in excess of 20 mg/day of prednisone (Note: Use of intra-articular or topical corticosteroids or eye drops containing corticosteroids is acceptable.), or Inhaled corticosteroids;
• Known history of autoimmune conditions including, but not limited to: rheumatoid arthritis, multiple sclerosis, lupus erythematosus, scleroderma, sarcoidosis, inflammatory bowel disease, idiopathic thrombocytopenia purpura, Graves' disease, or Hashimoto's thyroiditis;
• Current requirement for anti-coagulation therapy that prolongs PT or aPTT 7. History of prior malignancy except: Curatively treated non-melanoma skin cancer; Solid tumor treated curatively >5 years previously without evidence of recurrence; or History of other malignancy that in the Investigator's opinion would not affect the determination of study treatment effect (e.g., superficial bladder cancer, or carcinoma in situ of the prostate, cervix, or breast);
• Non-healed wound;
• Prior adjuvant therapy for current melanoma diagnosis;
• History of any clinically significant cardiovascular disorder (i.e., symptoms above Class II per New York Heart Association [NYHA] Functional Classification);
• History of serious allergic reaction to yeast or yeast-derived products, including known or suspected hypersensitivity reaction to sargramostim;
• Pregnant, breastfeeding, or planning to become pregnant during the study;
• Received any other investigational therapy within 28 days of Day 1; or
• Any concurrent medical condition that, in the opinion of the Investigator, would complicate or compromise compliance with the study or the well-being of the subject
