10. Patients that received interferon, GM-CSF, or experimental cancer vaccines for melanoma in the adjuvant setting are eligible. Prior radiation therapy for metastatic melanoma is permitted provided the patient has un-irradiated metastatic sites for response evaluation and any toxicity has returned to Grade 1
or baseline (patients with mild lymphedema following radiotherapy are allowed).
11. Patients with brain metastases should be at least 4 weeks from craniotomy and resection or stereotactic radiosurgery. MRI/CT of the brain performed within 2 weeks from screening fails to show new metastases and they are off of steroids for at least 2 weeks. Patients previously treated with whole brain radiotherapy are eligible if they are without tumor progression in the brain at least 8 weeks from completion of radiotherapy and are asymptomatic and off of steroids for at least 2 weeks.
12. Fertile patients and/or their partners must declare simultaneous use of two forms of birth control during the treatment period and up to 4 months after the last treatment of CT-011. The decision for appropriate methods to prevent pregnancy should be determined by discussions between the investigator and the study subject.
13. Ability and willingness to give informed consent. |

E.4 | Principal exclusion criteria |
1. Patients with uveal melanoma.
2. Active autoimmune disease, symptoms or conditions except for vitiligo, type I diabetes, treated thyroiditis, asymptomatic laboratory evidence of autoimmune disease (eg: + ANA, +RF, antithyroglobulin antibodies) or mild arthritis requiring no therapy or manageable with NSAIDs.
3. Known major immunodeficiency
4. Unresolved immune related adverse events following prior biological therapy
5. Participation in any other clinical trial involving another investigational agent within 4 weeks prior to first dosing of study agent and anti-CTLA4 therapy given within 6 weeks prior to first dosing.
6. Prior anti PD-1, anti PD-L1 or PD-L2 therapy.

lung disease should be evaluated with pulmonary function tests: Patients with the FEV1 <1.5 liters or <50% or FVC <50% of predicted should be excluded.
Borderline cases must be discussed with the Study Medical Monitor.
11. Patients on corticosteroids (inhaled or oral steroids for treating mild asthma treated by a low dose at a maximum of 500 micrograms per day for up to 10 consecutive days or allergies or topical steroids for localized -< 5% of body surface area- dermatitis are allowed) or any other type of immunosuppressive
agent (e.g., methotrexate, chloroquine, azathioprine, cyclophosphamide)
12. Patients with history of second malignancies are eligible provided that they have been free of recurrence from second malignancy for at least 5 years, except that the following are allowed: basal cell cancer (BCCa) or squamous cell cancer (SCCa) of the skin, or carcinoma in situ of the breast or cervix or localized
prostate cancer detected via biopsy only and being treated with “watchful waiting”. Each case must be discussed with the Study Medical Monitor prior to registration.
13. Patients with symptomatic uncontrolled brain metastasis that is associated with significant brain edema requiring steroid therapy. Patients with spinal cord metastasis or meningeal carcinomatosis.
14. Patients who are ineligible for imaging by CT and MRI due to suspected or known allergy to contrasting agents or patients who are ineligible for CT scan and have an implanted pacemaker (thus ineligible for MRI).
15. Women of child bearing potential who are pregnant as evidenced by positive serum pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) done within 72 hours of first dosing or nursing.
16. Any condition that, in the clinical judgment of the treating physician, is likely to prevent the patient from complying with any aspect of the protocol or that may put the patient at unacceptable risk.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint for this study is the objective response rate (ORR) by Immune
Related Response Criteria (irRC) in patients with metastatic melanoma treated with CT-
011
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The primary endpoint will be the objective response rate (ORR) after first administration of CT-011 that will record the best overall response from start of treatment until disease progression. Clinical responses will be evaluated by CT scan. Objective clinical responses will be determined by irRC. Response according to RECIST 1.1 will also be assessed and recorded. Complete response (irCR) or partial response (irPR) will be confirmed via subsequent assessment performed between 4 and 6 weeks later. ORR will be evaluated every 8-10 weeks for up to 12 months after first administration of CT-011. |
|
E.5.2 | Secondary end point(s) |
The secondary endpoints are to:
o Safety and tolerability of CT-011
o Progression-free survival from time of randomization, by irRC
o Overall survival from time of randomization
o Duration of response by irRC
o Immunogenicity of CT-011
o Monitoring peripheral lymphocyte cell surface markers: CD4, CD8,
CD45RO, CD62L, CCR7, CD27, CD127, CD25, FoxP3 & CD279 (PD-1)
(in US centers only) |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Secondary endpoints will include the safety and tolerability of CT-011, the rate of progression- free and overall survival to be evaluated every 8-10 weeks for up to 12 months after first administration of CT-011, the duration of response,
peripheral lymphocyte cell surface markers and the immunogenicity of CT-011. Blood samples for immunogenicity evaluation will be collected on Day 1, Week 16, 24, 34 and End of Study Visit.
