Full Description

This is a phase 2a, open-label study of T3011 given via intratumoral (IT) injection in combination with Cobimetinib given via oral administration in patients with advanced melanoma. This study is planned to enroll approximately 62~68 patients with BRAF V600E/V600K mutation-positive or RAS mutation-positive, which will be conducted in 2 parts (part 1 and part 2).

Eligibility Criteria

Inclusion Criteria

All patients must meet the following criteria for inclusion:

Patient has provided informed consent prior to initiation of any study-specific activities/procedures.
Male or female age ≥ 18 years at the time of informed consent.
Willingness to provide pre-and post-treatment fresh tumor biopsy specimens as specified in the Schedule of Study Procedures and Assessments (Table 1).
Histologically confirmed diagnosis of malignant melanoma (except for uveal melanoma).
Patient with stage IIIB to IV advanced malignant melanoma (as defined by American Joint Committee on Cancer [AJCC] staging manual version 8.0) that is not surgically resectable, failed for standard of care (SOC) therapy or in the opinion of the investigator not suitable for SOC therapy. SOC may include, but not be limited to chemotherapy, targeted therapy or immunotherapy.
BRAF V600E/V600K mutation-positive (applied to part 1 and part 2 cohort 1) or RAS mutation-positive (applied to part 1 and part 2 cohort 2). BRAF V600E/V600K and RAS mutation status result from diagnosis of tumor histopathology should be provided during Screening. If the patient is unable to provide, testing will be required during the Screening period in local laboratory.
Measurable disease defined as one or both of the following:

(1) At least 1 melanoma lesion that can be accurately and serially measured in at least 2 dimensions sand for which the longest diameter is ≥ 10 mm and with perpendicular diameter ≥ 5 mm as measured by contrast-enhanced or spiral CT scan for visceral or nodal/soft tissue disease. Lymph nodes must measure > 15 mm in their short axis to be considered measurable by CT scan.

(2) At least 1 superficial cutaneous or subcutaneous melanoma lesion that can be accurately and serially measured in at least 2 dimensions and for which the short axis is ≥ 5 mm as measured by calipers.

(3) Previously irradiated lesions can be considered as measurable disease only if progressive disease has been unequivocally documented at that lesion since radiation.

8. Injectable disease (i.e., suitable for direct injection or through the use of ultrasound [US] or CT guidance) defined as follows:

At least 1 injectable melanoma lesion ≥ 5 mm in longest diameter, or in the opinion of the investigator the lesion can be injected.

9. Eastern Cooperative Oncology Group (ECOG) performance status 0-1.

10. Life expectancy ≥ 12 weeks.

11. Adequate bone marrow function defined by ANC of ≥ 1.5 × 109/L, platelet count of ≥ 100 × 109/L, and hemoglobin (Hb) of ≥ 8.5 g/dL.

12. Adequate hepatic function defined as AST/ALT ≤ 3 × ULN and total bilirubin ≤ 1.5 × ULN (except patients with Gilbert's Syndrome, wherein total bilirubin < 3.0 mg/dL is acceptable; patients with hepatic metastases: AST and/or ALT ≥ 5 × ULN is acceptable; patients with hepatic or bone metastases: ALP ≥ 5 × ULN is acceptable).

13. Adequate renal function defined as creatinine clearance > 50 mL/min as determined by the Cockcroft-Gault equation.

14. Adequate coagulation function defined as international normalization ratio (INR)/prothrombin time (PT) ≤ 1.5 × ULN, and partial thromboplastin time (PTT)/ activated PTT (aPTT) ≤ 1.5 × ULN, unless the patient is receiving anticoagulant therapy, in which case PT and PTT/aPTT must be within therapeutic range of intended use of anticoagulants.

15. Resolution of all prior anti-tumor therapy toxicities (except for alopecia) to ≤ NCI CTCAE version 5.0 Grade 1.

Note: patients with immune-mediated endocrinopathies on replacement therapy are eligible. Patients with endocrine-related AE who can recover to ≤ NCI CTCAE version 5.0 Grade 1 after hormone replacement therapy, in the judgment of the investigator, have no impact on the safety and efficacy of this study can also be enrolled. Patients with toxicities attributed to the prior anti-tumor therapy and not expected to resolve, such as neuropathy or ototoxicity after platinum-based therapy, are permitted to enroll. Patients with other toxicities > NCI CTCAE version 5.0 Grade 1 may be enrolled with approval from the sponsor.

16. Female patients must be surgically sterile (or have a monogamous partner who is surgically sterile), or be at least 2 years postmenopausal, or commit to using 2 acceptable forms of birth control (defined as the use of an intrauterine device, a barrier method with spermicide, condoms, any form of hormonal contraceptives, or abstinence) for the duration of the study and for 6 months following the last dose of study treatment. Male patients must be sterile (biologically or surgically) or commit to the use of a reliable method of birth control (condoms with spermicide) for the duration of the study and for 6 months following the last dose of study treatment.

17. Women of childbearing potential (WCBP) must have a negative serum pregnancy test at Screening within 14 days before the first dose of study treatment on W1D1 and a negative urine pregnancy test pre-dose on W1D1 (assessment not required at W1D1 if completed within the previous 7 days of W1D1).

Note: A woman is considered to be of childbearing potential if she is postmenarchal, has not reached a postmenopausal state (≥ 12 continuous months of amenorrhea with no identified cause other than menopause), and is not permanently infertile due to surgery (i.e., removal of ovaries, fallopian tubes, and/or uterus) or another cause as determined by the investigator (e.g., Müllerian agenesis).
