KEYNOTE 890

• The study will be comprised of a screening period, a treatment period (up to 2 years) and a long-term follow-up.
• Eligible patients will be treated with intratumoral TAVO-EP to the accessible lesions on Days 1, 5 and 8 every 6 weeks, with IV pembrolizumab (200mg) on Day 1 of each 3-week cycle for 18 TAVO-EP cycles, 35 pembrolizumab cycles (from baseline), and with an approved chemotherapy per standard of care, nab-paclitaxel on Days 1, 8, 15 every 4 weeks. As many accessible lesions may be treated as deemed feasible by the treating physician assuming the size of each lesion is greater than or equal to 0.3 cm x 0.3 cm.
• Long-Term Follow-Up: All subjects will be followed after End of Study (EOS) visit for Serious Adverse Events (SAEs) (through 90 days from last dose of study drug) and long-term survival status. EOS visit will occur 4 weeks after last study treatment administration.

Patients will receive treatment in a three-step process:

• A needle is used to inject the human gene IL-12 (tavo) directly into the tumor;
• Followed by a small electrical current of less than 3 seconds (electroporation) to allow the IL-12 gene to readily enter the tumor, every 6 weeks, for the duration of the study.
• There is a 30-minute infusion of pembrolizumab once every three weeks.
• There is a 30-minute infusion of nab-paclitaxel chemotherapy per standard of care every four weeks.

Tests and procedures during this study include:

• Ongoing measurements and imaging of melanoma lesions, physical exams, and samples of blood, tissue, stool and tumor biopsies for the immune monitoring program.
• Data analyzed from these samples will allow for a deeper understanding of how to best fight cancer in this and future clinical trials.

Q: Who is involved in clinical research studies?
A: This clinical research study is supported by doctors, nurses, and other healthcare professionals. The commitment of each participant and the entire study team is important to help meet the objectives of the study. This study follows strict ethical and governmental guidelines to ensure that participants’ rights are protected while the information is being collected.

Q: How long will I take part in this study?
A: The study will be comprised of a screening period, a treatment period (up to 2 years) and a long-term follow-up. Eligible patients will be treated with intratumoral TAVO-EP to the accessible lesions on Days 1, 5 and 8 every 6 weeks and with IV pembrolizumab (200mg) on Day 1 of each 3-week cycle for 18 TAVO EP cycles, 35 pembrolizumab cycles (from baseline), and with an approved chemotherapy per standard of care, limited to nab-paclitaxel on Days 1, 8, 15 every 4 weeks. As many accessible lesions may be treated as deemed feasible by the treating physician assuming the size of each lesion is greater than or equal to 0.3 cm x 0.3 cm.

Q: What happens if I leave the study?
A: You are free to leave the study at any point. Leaving the study will not impact your care.

Q: What will happen to my data?
A: Data will be collected, handled, and processed in compliance with applicable regulation guidelines. It will not be shared with anyone other than in circumstances that will be explained in your consent form.

Q: Will my data identify me?
A: Your identity will not be available to the company sponsoring this clinical trial or any of their research partners.
