Refractory Melanoma

The goal of this clinical trial is to learn if DOC1021 + pIFN will be safe and will lead to tumor responses in patients with refractory melanoma. DOC1021 is a dendritic cell immunotherapy derived from a patient's own blood cells and loaded with antigens from the patient's tumor in the form of tumor lysate and mRNA. The goal is to stimulate a T cell immune response that eliminates tumor cells. The study consists of two components: an initial phase I safety study to confirm safety/tolerability of the treatment regimen, and, subsequently, a single-arm phase II cohort to assess efficacy of the treatment regimen. All participants will: * Take filgrastim subcutaneously x 5 doses and subsequently undergo a leukapheresis collection * Receive two doses of DOC1021 under image guidance 2 weeks apart * Receive subcutaneous pIFN injections weekly for a total of 4 doses in parallel with the DOC1021 injections * Undergo an optional image-guided perinodal DOC1021 booster injection approximately 6 months after the first DOC1021 dose along with additional subcutaneous pIFN injections at time of the booster and the subsequent week for a total of 2 pIFN doses * Visit the clinic regularly to assess quality of life, symptoms, medication use, imaging, bloodwork, and to receive optional treatment with anti-PD1 agents

To find the highest tolerable dose of IACS-6274 that can be given alone, in combination with bevacizumab and paclitaxel, or in combination with capivasertib to patients who have solid tumors. The safety and tolerability of the study drug(s) will also be studied.

To find the highest tolerable dose and recommended dose of PRAME-TCR-NK cells that can be given to participants with recurrent and/or refractory melanoma. The safety and tolerability of PRAME-TCR-NK cells will also be studied.
