About this trial

The goal of this study is to determine the activity of Perkileucel, a tumour infiltrating lymphocyte (TIL) adoptive cell transfer therapy (ACT), in patients with unresectable stage III or metastatic melanoma who have progressed on previous treatment with immune checkpoint inhibitors in the adjuvant or metastatic setting.

Study details:

All participants will receive the investigational treatment, Perkileucel. To create this therapy, participants need to undergo surgical excision of a melanoma lesion to harvest the TILs prior to treatment. Once the TILs have been manufactured, participants will be admitted to hospital to receive 5 days of chemotherapy to prepare their body (lymphodepletion) for the TIL-ACT. Treatment with TIL-ACT will then be given on Day 0 as a single intravenous infusion followed by up to 6 intravenous infusions of high-dose interleukin 2. Blood tests and other assessments will be performed regularly to monitor safety and response.

The total duration of the study is 8 years. Safety will be assessed throughout the full duration of the study. Patients will be monitored for delayed adverse events.

This study will show whether Perkileucel can help control melanoma that has not responded to other treatments and demonstrate feasibility of manufacture and delivery of this treatment in an Australian healthcare setting.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Adult patients = 18 years = 70 years of age.

ECOG 0-1 (Appendix A: Eastern Cooperative Oncology Group Performance Status Scale) with an estimated life expectancy of > 6 months

Histologically confirmed unresectable or stage IV melanoma as per AJCC 8th edition. Unresectable melanoma is defined where the lesions are deemed to be unresectable by the treating surgeon.

Metastatic melanoma with at least 1 surgically accessible metastatic lesion (or aggregate lesions) with an estimated minimum diameter of = 1.5 cm

Disqualifiers

Life expectancy of less than 3 months.

Metastatic uveal melanoma.

Requirement for immunosuppressive doses of systemic corticosteroids (>10 mg/day prednisone or equivalent) or other immunosuppressive drugs (e.g. mycophenolate, infliximab, or others) within the last 3 weeks prior to patient screening. Participants receiving steroids as replacement therapy for adrenocortical insufficiency at =10 mg/day of prednisone or another steroid equivalent dose are acceptable.

Participant has symptomatic untreated brain metastases.

Design model

Single group

Treatments tested in this trial

  • Tumour Infiltrating Lymphocytes Adoptive Cell Therapy

    Biological/Vaccine

    TILs are autologous melanoma reactive cells, that are harvested from patient's own melanoma tissue. Patients will receive the TIL-ACT by a single intravenous infusion on Day 0 at of dose of 5 x 10\^9 to 2 x 10\^11 TILs.

  • Cyclophosphamide + Fludarabine Lymphodepletive Conditioning

    Drug

    Five days prior to infusion of TIL-ACT, patients will receive a lymphodepleting chemotherapy with cyclophosphamide (60 mg/kg) once daily concurrently with fludarabine (25 mg/m\^2) IV once daily for 2 days followed by fludarabine (25mg/m\^2) once daily for 3 days.

  • Aldesleukin

    Drug

    Patients will receive up to 6 doses of intravenous aldesleukin (600 000 IU/kg IV) every 8-12 hours post the TIL-ACT infusion.

Trial outcomes

Primary outcomes

1

Assess the activity of TIL ACT in patients unresectable or metastatic melanoma resistant to anti-PD1 using objective response rate as per RECIST 1.1

Best objective response rate as per RECIST criteria 1.1

Time frame
From enrolment to 6 months, date of documented progression per RECIST criteria 1.1 or the date of subsequent anti-cancer therapy, whichever occurs first

Secondary outcomes

1

Median Progression Free Survival

Median, calculated as the date between randomisation and the date of documented progression per RECIST 1.1 to month 12 post Perkileucel infusion

Time frame
From enrolment to 12 months post infusion of Perkileucel
2

Median Overall Survival

Median, calculated by the date from randomisation to 12 months post Perkileucel infusion, or date of death

Time frame

From enrolment to 24 months post Perkileucel infusion
4

Median Overall Survival

Median, calculated by the date from randomisation to 24 months post Perkileucel infusion, or date of death

Time frame
From enrolment to 24 months post Perkileucel infusion
