Authorised Therapeutic exploratory (Phase II) Patients with diagnosis of unresectable clinical stage III or IV metastatic melanoma, with presence of injectable cutaneous, subcutaneous or nodal lesions and resistant to or progressing upon anti-PD1 immunotherapy

A phase 2 study of the efficacy of intratumorally administered L19IL2 or L19TNF or L19IL2/L19TNF, all in combination with systemic anti-PD1 Pembrolizumab, in stage III/IV unresectable melanoma patients with resistance to anti-PD1 checkpoint inhibitors (INTACT / MeRCI)

EU CTIS ID: 2024-519326-20-00

What this study is testing

The primary objective of the study is to demonstrate the efficacy of intralesional treatment with immunocytokines (L19IL2, or L19TNF, or L19IL2/L19TNF), in combination with systemic anti-PD1 immunotherapy with pembrolizumab, to induce objective responses in advanced melanoma patients with resistance to or progressing upon anti-PD1 checkpoint inhibitors.

1. >18 years of age on day of signing informed consent; 2. 3. Participant with histologically or cytologically confirmed diagnosis of unresectable metastatic melanoma at stage III B, C, D or IV M1a (AJCC 8th ed.). Patients with Stage IVM1b, M1c and M1d oligometastatic disease [up to 10 visceral lesions in aggregate including lung, liver, bone or brain, with or without lymph node involvement], are eligible.

16. Has an active infection requiring systemic therapy. 17. Has a history or current evidence of any condition, therapy, or laboratory abnormality, or other circumstance that might confound the results of the study or interfere with the participant's participation for the full duration of the study, such that it is not in the best interest of the participant to participate, in the opinion of the treating investigator. 18. Has a known psychiatric or substance abuse disorder that would interfere with the participant’s ability to cooperate with the requirements of the study. 19.

17. Willingness and ability to comply with the scheduled visits, treatment plan, laboratory tests and other study procedures
4. Patients must have confirmed primary resistance to or acquired resistance on treatment with an anti-PD1/L1 monoclonal antibody (mAb) administered either as monotherapy, or in combination with other checkpoint inhibitors or other therapies. PD-1 treatment progression is defined by meeting all of the following criteria: a. Has received at least 2 doses of an approved anti-PD-1/L1 mAb. b. Has demonstrated disease progression (PD) after PD-1/L1 as defined by RECIST v1.1. The initial evidence of PD is to be confirmed by a second assessment no less than four weeks from the date of the first documented PD, in the absence of rapid clinical progression. c. Progressive disease has been documented within 12 weeks from the last dose of anti-PD-1/L1 mAb. i. Progressive disease is determined according to iRECIST. ii. This determination is made by the investigator. Once PD is confirmed, the initial date of PD documentation will be considered the date of disease progression. Primary resistance is defined in Table 4 (reproduced from [2]. Recommendations of the Society for Immunotherapy of Cancer - Immunotherapy Resistance Taskforce)
5. Patients harboring the BRAF mutation who received BRAF/MEK inhibition (or declined BRAF/MEK inhibitors) and received thereafter anti-PD1 therapy showing resistance to such immunotherapy are eligible to the study
6. Eligible subjects must have measurable disease (according to RECIST v1.1) as assessed by the local site investigator/radiology. Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions. Eligible subjects must be candidates for intralesional therapy with at least one injectable cutaneous, subcutaneous, or nodal metastatic melanoma lesion (≥ 5 mm in longest diameter) or multiple injectable lesions that in aggregate have a diameter of ≥ 5 mm
9. Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.
10. Have adequate organ function as defined in table (Table 5). Specimens must be collected within 14 days prior to the start of study treatment
11. Be able to provide a core or excisional lymph node biopsy for biomarker analysis from an archival or newly obtained biopsy at Screening. In addition, participants may provide additional biopsy at Week 18 and at the time of discontinuation due to progression.
12. 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) a negative serum HBV-DNA test is also required.
7. A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies: a.) Not a woman of childbearing potential (WOCBP) b.) A WOCBP who agrees to follow contraceptive guidance during the treatment period and for at least 120 days after the last dose of study treatment. WOCBP must be using for the time period indicated highly effective contraception methods. WOCBP and effective contraception methods are defined by the "Recommendations for contraception and pregnancy testing in clinical trials" issued by the Head of Medicine Agencies' Clinical Trial Facilitation Group 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)
