The drug exhibits a multimodal mechanism. It not only reverses chemoresistance and halts tumor growth but also 'turns cold tumors hot' by forcing cancer cells to display markers that make them visible to the immune system. This dual action of direct attack and immune activation creates a powerful synergistic effect.

An innovative strategy for solid tumors involves using bispecific T-cell engagers to target the tumor stroma—the protective fibrotic tissue surrounding the tumor. This novel approach aims to first eliminate this physical barrier, making the cancer cells themselves more vulnerable to subsequent immune attack.

Instead of focusing solely on T-cells, Create's platform first targets myeloid cells, which constitute up to 60% of some solid tumors. Programming these cells transforms the tumor microenvironment, enabling a 5-10x influx of CD8 T-cells. This overcomes a key barrier for T-cell therapies in solid tumors.

The future of GYN oncology immunotherapy is diverging. For responsive cancers like endometrial, the focus is on refining biomarkers and overcoming resistance. For historically resistant cancers like ovarian, the strategy shifts to using combinatorial approaches (e.g., CAR-NKs, vaccines) to fundamentally alter the tumor microenvironment itself, making it more receptive to an immune response.

Experts express strong confidence in the effectiveness of radiation therapy for epithelioid sarcomas, noting the tumors are very sensitive to it. In difficult locally advanced cases, radiation is a key modality for gaining disease control and managing pain, with growing interest in combining it with immunotherapy to enhance its effects.

To combat immunosuppressive "cold" tumors, new trispecific antibodies are emerging. Unlike standard T-cell engagers that only provide the primary CD3 activation signal, these drugs also deliver the crucial co-stimulatory signal (e.g., via CD28), ensuring full T-cell activation in microenvironments where this second signal is naturally absent.

While immunotherapy was a massive leap forward, Dr. Saav Solanki states the next innovation frontier is combining it with newer modalities. Antibody-drug conjugates (ADCs) and T-cell engagers are being used to recruit the immune system into the tumor microenvironment, helping patients who don't respond to current immunotherapies.

Rather than expecting cell therapies (CAR-T, TIL) to eradicate every cancer cell, Dr. Radvanyi reframes them as powerful adjuvants. Their role is to inflict initial damage, kill tumor cells, and release antigens, creating an opportunity to prime a broader, secondary immune response with other modalities like vaccines or checkpoint inhibitors.

For epithelioid sarcoma, the timeline of metastatic recurrence dictates treatment sequencing. Rapid progression (e.g., within three months of local therapy) indicates aggressive biology requiring fast-acting cytotoxic chemotherapy. The epigenetic drug tazometastat takes much longer to work and is better suited for slower-growing, asymptomatic disease.
