trial of an intratumoral injections of inxn-3001 in subjects with stage iii or iv melanoma

Conditions: Melanoma

Summary: the purpose of this study is to test the safety of an investigational combination drug/immunotherapy for the treatment of stage iii/iv melanoma.

this study will examine the effects of an oral activator ligand administration to modulate the timing of gene expression of human il-12 by adenovirus-transduced dendritic cells injected into tumors.

Eligibility criteria:
inclusion criteria: 1. males or females of all races ≥ 18 years of age and ≤ 75 years of age; 2. unresectable stage iii c (in transit) or stage iv melanoma (m1a, m1b, m1c with ldh ≤ 2x uln), arising from primary cutaneous, mucosal, or subungual melanoma of any tumor thickness or from an unknown primary site; 3. a minimum of 2-3 accessible nonvisceral lesions (longest diameter ≤3 cm) or palpable tumor-involved lymph nodes (longest diameter ≤5 cm) for intratumoral injections (inxn-3001) and biopsies; 4. ecog performance status of 0 or 1; 5. patients without visible brain metastases as assessed by contrast-enhanced mri scan within 6 weeks prior to receiving study treatment; 6. adequate baseline hematological and organ function, assessed by laboratory values within 42 days (6 weeks) prior to study entry and prior to repeat treatment cycles with inxn-1001 as follows: hemoglobin ≥ 10 g/l, granulocytes \> 2500/mm3, lymphocytes \> 1000/ mm3, platelets \> 100,000/ mm3, serum creatinine \ 500/ mm3; 7. an expected survival of at least approximately 6 months in the opinion of the investigator (as assessed mainly by performance status); 8. females must be post-menopausal or surgically sterile or practice effective contraception; men who are not surgically sterile and whose partners are not post-menopausal or surgically sterile must practice effective contraception; 9. normal coagulation parameters as measured by pt/ptt; 10. signed, irb-approved voluntary written informed consent. exclusion criteria: 1. active, acute viral, bacterial, or fungal infections requiring specific therapy; 2. hiv-infection due to concerns about ability to mount an effective immune response; 3. active autoimmune disease requiring steroids (\>10 mg prednisolone or comparable) or other immunosuppressive therapy; 4. patients with detectable brain metastases at the time of screening (or within 6 weeks prior to receiving study treatment), as assessed by contrast-enhanced mri scans; 5. patients with one or more lesion(s) \> 3cm (ld) or palpable, tumor-involved lymph node(s) \>5 cm (ld); 6. patients with a hemoglobin of \< 10 g/l; 7. presence of stage iv visceral metastases or other distant metastases if ldh \>2 x uln; 8. patients who have previously been treated with inxn-3001 and inxn-1001; 9. recipients of organ allografts; 10. other concurrent, clinically active malignant disease, with the exception of other cancers of the skin; 11. less than 30 days (before the first dose of study medication) have elapsed since the completion of prior chemotherapy, hormonal therapy, radiotherapy, immunotherapy, or any first line therapy; 12. clinically significant cerebrovascular disease; 13. history of or concurrent severe cardiac insufficiency (new york heart association class iii or iv) or coronary artery disease; 14. qtc interval of \>470 ms on screening; 15. inability to measure the qt interval due to conduction abnormalities such as bundle branch block (left or right) or persistent cardiac arrhythmia e.g. atrial fibrillation, or cardiac pacemaker; 16. long qt syndrome or family history of sudden cardiac death in young family members; 17. concomitant use of medication known to affect ventricular repolarization; 18. cardiac comorbidity such as a left ventricular ejection fraction \<45%, myocardial infarction, persistent angina, or cardiac surgery within 3 months prior to enrollment; 19. uncontrollable hypertension (\>150 mm hg systolic or \>100 mm hg diastolic); 20. acute medical conditions such as ischemic heart or lung disease that may be considered an unacceptable anesthetic or operative risk; 21. history of or current bleeding or uncorrected clotting disorders; 22. concurrent immunosuppressive therapy such as corticosteroids (\>10mg prednisolone or comparable) and cyclosporin a; 23. concurrent investigational treatments, or treatment with any investigational treatment within the past 30 days (prior to the first dose of study medication); 24. concurrent medications that are metabolized by the cyp 3a4 pathway; 25. females who are lactating or pregnant; 26. a body mass index (bmi) greater than or equal to 40 kg/m2; aa. patients who have a history of hypersensitivity that may relate to any component of the product, e.g. to benzoic acid that might be related to inxn-1001, which contains two benzene rings; bb. any medical or psychiatric condition which, in the opinion of the investigator, would unacceptably reduce the safety or delivery of the proposed treatment, or would preclude obtaining voluntary informed consent.
