The discovery and application of immune checkpoint inhibitors (ICI) have significantly promoted cancer treatment. However, the response rate is still low in gastrointestinal (GI) cancers. To explore novel adjuvant treatment options, we performed fecal microbiota transplantation (FMT) of healthy donors on 10 GI cancer patients with resistance to anti-PD-(L) 1 treatment. The combination of FMT and anti-PD1 treatment was well tolerated and no serious adverse reaction was observed. Two out of 10 patients restored clinical responsiveness to anti-PD1 after FMT. Clinical benefits were shown to be associated with better colonization of co-occurred immunogenic microbes from donors, alongside activated immune status reflected by the peripheral immune cell population. Moreover, we identified microbial signatures of ICI responsiveness and validated in an independent cohort. Our study demonstrates the feasibility of FMT as a potential adjuvant therapy for ICI irresponsive GI cancer patients and laid a foundation for LBP / consortia development to enhance ICI efficacy.

The present invention relates to: a temperature-sensitive hydrogel for cancer treatment; a photothermal composition comprising the hydrogel as an active ingredient; and a preparation method for the temperature-sensitive hydrogel for cancer treatment. The temperature-sensitive hydrogel of the present invention includes gold nanostars as active ingredients, and thus can generate heat by light irradiation, thereby exhibiting a photothermal therapy effect. In addition, the hydrogel temperature increases so that the release of nitric oxide (NO) from S-nitrosocysteine can be induced. In addition, the temperature-sensitive hydrogel of the present invention includes S-nitrosocysteine as an active ingredient so that, upon a temperature rise due to a photothermal reaction, the penetration of drugs into a tumor site can be improved by the release of NO, and at the same time, apoptosis of cancer cells can be directly caused; and includes an immunotherapy agent as an active ingredient so that tumor size can be effectively suppressed even with the passage of time. Therefore, as a material that enables complex treatment combined with photothermal therapy and immunotherapy, the temperature-sensitive hydrogel of the present invention having the aforementioned effect can be usefully utilized in the field of medicine for cancer treatment.

Shear-thinning biomaterial technology offers enables polymers and drugs loaded inside such polymers to be easily delivered directly through catheters into target area for use, for example, in cancer therapy and immunotherapy. When a force above a certain threshold is applied to inject such materials, they “thin” and behaves as a semi-solid, allowing the material to readily flow through a catheter. When the force is removed, the material instantly becomes a soft solid with significant cohesive properties that prevent it from dislodging or breaking up. We have developed novel shear-thinning biomaterials using spherical silica nanoparticles and gelatin-based polymers. Rheological tests confirm that these materials have excellent shear-thinning properties and further have improved material properties (e.g. improved stability profiles) as compared conventional materials available to medical professionals.
