Studien-Informationen

Detailed Description:

Phase III, open-label, randomized, controlled multi-center study. In the study, 214 patients

will be enrolled and parallel assigned (via automated randomization system) in a 1:1 fashion

to one of two different arms:

ARM 1:

Patients in Arm 1 will receive multiple intratumoral administrations into all injectable

cutaneous, subcutaneous, and nodal tumors of a mixture of L19IL2 and L19TNF once weekly for

up to 4 weeks (or until all injectable tumors have disappeared, or intolerance to study

treatment or in the opinion of the investigator immediate surgical resection or any other

treatment for melanoma is warranted, whichever occurs first). The whole volume of

L19IL2/L19TNF will be distributed among all injectable lesions.

Newly occurring injectable melanoma lesions within the 4 weeks treatment period will also be

treated as described. For the new lesions the treatment period will not be extended beyond

the pre-defined 4 week- treatment period with a clock start at the time of the first

intralesional L19IL2/L19TNF injection. Surgical resection of all existing metastases will

follow within 4 weeks after end of treatment. Surgery will be performed after the safety

evaluation carried out at week 5 and, if indicated, may be carried out on the same day of the

safety evaluation.

Post-surgery EMA-approved adjuvant therapy is allowed at discretion of the treating

physician.

ARM 2:

Patients in Arm 2 will receive directly surgical resection of melanoma tumor lesions within 4

weeks after randomization.

Post-surgery EMA-approved adjuvant therapy is allowed at discretion of the treating

physician.

Patients will be followed on a regular basis for the primary outcome until 36 months from

randomization and up to 60 months for overall survival.

Expected patient enrollment interval: 60 months. Duration of individual patient's

participation: up to 60 months. End of treatment corresponds to the day of surgery for

patients randomized to both Arm 1 and Arm 2.

End of study corresponds to the last patient last visit (LPLV). The final primary efficacy

analysis will be conducted when the 95th recurrence event is observed.

Ein-/Ausschlusskriterien

Inclusion criteria:

1. Diagnosis of malignant melanoma of the skin with locally advanced disease as defined

by clinical stage III B and III C according to AJCC 7th Ed., eligible for complete

surgical resection.

2. Eligible subjects must have measurable disease and must be candidate for intralesional

therapy with at least one injectable cutaneous, subcutaneous, or nodal melanoma lesion

(≥ 10 mm in longest diameter) or with multiple injectable lesions that in aggregate

have a longest diameter of ≥ 10 mm.

3. Prior anti-tumor treatment for the primary melanoma lesion, including surgery and

approved adjuvant treatments (e.g., radiotherapy, immune checkpoint inhibitors,

BRAF/MEK inhibitors, etc.) is allowed.

4. Males or females, age ≥ 18 years.

5. ECOG Performance Status/WHO Performance Status ≤ 1.

6. Life expectancy of at least 24 months (see paragraph 6.3.1).

7. Absolute neutrophil count > 1.5 x 109/L.

8. Hemoglobin > 9.0 g/dL.

9. Platelets > 100 x 109/L.

10. Total bilirubin ≤ 30 µmol/L (or ≤ 2.0 mg/dl).

11. ALT and AST ≤ 2.5 x the upper limit of normal (ULN).

12. Serum creatinine < 1.5 x ULN.

13. LDH serum level ≤ 1.5 x ULN.

14. Documented negative test for HIV, HBV and HCV. For HBV serology, the determination of

HBsAg and anti-HBcAg Ab is required. In patients with serology documenting previous

exposure to HBV (e.g., anti-HBsAg and/or anti-HBc Ab) negative serum HBV-DNA is also

required.

15. All acute toxic effects (excluding alopecia) of any prior therapy must have resolved

to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events

(CTCAE) (v4.03) Grade ≤ 1 unless otherwise specified above.

16. Negative pregnancy test at screening for Women Of Childbearing Potential (WOCBP*).

Pregnant women are not allowed to participate to this study. WOCBP must be using, from

the screening to three months following the last study drug administration, highly

effective contraception methods, as defined by the "Recommendations for contraception

and pregnancy testing in clinical trials" issued by the Head of Medicine Agencies'

Clinical Trial Facilitation Group and which include, for instance, progesterone-only

or combined (estrogen- and progesterone-containing) hormonal contraception associated

with inhibition of ovulation, intrauterine devices, intrauterine hormone-releasing

systems, bilateral tubal occlusion, vasectomized partner or sexual abstinence.

Pregnancy test will be repeated at the Safety Visit (only WOCBP and only for patients

in Arm 1).

17. Male patients with WOCBP partners must agree to use simultaneously two acceptable

methods of contraception (i.e., spermicidal gel plus condom) from the screening to

three months following the last study drug administration.

18. Evidence of a personally signed and dated informed consent document indicating that

the subject has been informed of all pertinent aspects of the study.

19. Willingness and ability to comply with the scheduled visits, treatment plan,

laboratory tests and other study procedures.

- Women of childbearing potential are defined as females who have experienced

menarche, are not postmenopausal (12 months with no menses without an alternative

medical cause) and are not permanently sterilized (e.g., tubal occlusion,

hysterectomy, bilateral oophorectomy or bilateral salpingectomy).

Exclusion Criteria:

1. Uveal melanoma, mucosal melanoma or melanoma with unknown primary.

2. Evidence of distant metastases at screening.

3. Previous or concurrent cancer that is distinct in primary site or histology from the

cancer being evaluated in this study except cervical carcinoma in situ, treated basal

cell carcinoma, superficial bladder tumors (Ta, Tis & T1), second primary melanoma in

situ or any cancer curatively treated ≥ 5 years prior to study entry.

4. Presence of active infections (e.g., requiring antimicrobial therapy) or other severe

concurrent disease, which, in the opinion of the investigator, would place the patient

at undue risk or interfere with the study.

5. History within the last year of acute or subacute coronary syndromes including

myocardial infarction, unstable or severe stable angina pectoris.

6. Inadequately controlled cardiac arrhythmias including atrial fibrillation.

7. Heart insufficiency (> Grade II, New York Heart Association (NYHA) criteria).

8. LVEF ≤ 50% and/or abnormalities observed during baseline ECG and Echocardiogram

investigations that are considered as clinically significant by the investigator.

9. Uncontrolled hypertension.

10. Ischemic peripheral vascular disease (Grade IIb-IV).

11. Severe diabetic retinopathy.

12. Active autoimmune disease.

13. History of organ allograft or stem cell transplantation.

14. Recovery from major trauma including surgery within 4 weeks prior to enrollment.

15. Known history of allergy to IL2, TNF, or other human proteins/peptides/antibodies or

any other constituent of the product.

16. Breast feeding female.

17. Anti-tumor therapy (except allowed treatments listed at point 3 of Inclusion criteria)

within 4 weeks before enrollment.

18. Previous in vivo exposure to monoclonal antibodies for biological therapy (except

allowed treatments listed at point 3 of Inclusion criteria) in the 6 weeks before

enrollment.

19. Planned administration of growth factors or immunomodulatory agents (except allowed

treatments listed at point 3 of Inclusion criteria) within 7 days before enrollment.

20. Patient requiring or taking corticosteroids or other immunosuppressant drugs on a

long-term basis. Limited use of corticosteroids to treat or prevent acute

hypersensitivity reactions is not considered an exclusion criterion.

21. Any conditions that in the opinion of the investigator could hamper compliance with

the study protocol.

22. Previous enrolment and randomization in this same study.
