Clinical management of human cancer is dependent on the accurate monitoring of residual and recurrent tumors. We have developed a method, called personalized analysis of rearranged ends (PARE), which can identify translocations in solid tumors. Analysis of four colorectal and two breast cancers revealed an average of nine rearranged sequences (range 4 to 15) per tumor. Polymerase chain reaction with primers spanning the breakpoints were able to detect mutant DNA molecules present at levels lower than 0.001% and readily identified mutated circulating DNA in patient plasma samples. This approach provides an exquisitely sensitive and broadly applicable approach for the development of personalized biomarkers to enhance the clinical management of cancer patients.

The present invention relates to methods for predicting the probability of a treatment response of a human cancer patient to an immune checkpoint blocker treatment e.g. with anti PD-1, and to methods for predicting the probability of survival of a human cancer patient following an immune checkpoint blocker treatment, and to apparatuses and kits which can be used in these methods.

This document relates to materials and methods involved in treating cancer. For example, materials and methods for using one or more oncolytic viruses (e.g., one or more oncolytic viruses) to treat cancer in a mammal (e.g., a human) identified as having a cancer likely to respond to oncolytic virotherapy are provided.

Targeting immune checkpoints, such as Programmed cell Death 1 (PD1), has improved survival in cancer patients by unleashing exhausted CD8+ T-cell thereby restoring anti-tumor immune responses. Most patients, however, relapse or are refractory to immune checkpoint blocking therapies. Here, the inventors show that NRP1 is recruited in the cytolytic synapse of PD1+CD8+ T-cells, interacts and enhances PD-1 activity. In mice, CD8+ T-cell specific deletion of Nrp1 improves spontaneous and anti PD1 antibody anti-tumor immune responses. Likewise, in human metastatic melanoma, the expression of NRP1 in tumor infiltrating CD8+ T-cells predicts poor outcome of patients treated with anti-PD1 (e.g. pembrolizumab). Finally, the combination of anti-NRP1 and anti-PD1 antibodies is synergistic in human, specifically in CD8+ T-cells anti-tumor response. Thus the therapeutic inhibition of NRP1 alone or combined with an immune checkpoint inhibitor (e.g. anti-PD1 antibody) could efficiently repress tumor growth in human cancer. The present invention also relates to multispecific antibodies comprising at least one binding site that specifically binds to an immune checkpoint molecule (e.g. PD-1), and at least one binding site that specifically binds to NRP-1. The present invention also relates to a population of cells engineered to express a chimeric antigen receptor (CAR) and wherein the expression of NRP-1 in said cells is repressed.

The anti-cancer use of a camptothecin derivative which demonstrates a surprising resistance to the degrading effects of Human Serum Albumin ("HSA") in vivo is disclosed. Since HSA represents about half of serum protein in human blood, previous camptothecins generally worked poorly or not at all in vivo due to inactivation by HSA among other factors. Since NSS-01 is similar in mechanism of action to other camptothecins, and as demonstrated herein has both: (i) greater anti-tumor activity against various human cancers and (ii) less toxicity at therapeutic dosing - than topotecan and irinotecan; and without wishing to be bound by theory, NSS-01 demonstrated desirable antitumor activity against adenocarcinomas, it therefore should demonstrate desirable antitumor activity against other cancers that are susceptible to Topoisomerase I inhibitors.

The invention discloses a preparation method and application of pleuromutilin and derivatives thereof.

Wherein the C8-position axially substituted derivative has particularly outstanding advantages in the aspect of inhibiting TrxR enzyme activity, and compared with a parent compound pleuromutilin and a positive control drug Jinnofen, the TrxR inhibiting efficacy of the C8-position axially substituted derivative is improved to 9 times and 16.7 times respectively.

NEO-201 is a humanized IgG1 monoclonal antibody (mAb) that is highly reactive against the majority of tumor tissues from a number of different cancer tumors, including colon, pancreatic, gastric, lung, breast and uterine cancers, but the majority of normal tissues are not recognized by such antibodies. Functional assays reveal that NEO-201 is capable of mediating both antibody dependent cytotoxicity (ADCC) and complement dependent cytotoxicity (CDC) against tumor cells. Furthermore, the growth of human pancreatic xenograft tumors in vivo is greatly weakened by using NEO-201 alone and in combination with human peripheral blood mononuclear cells (PBMCs) that are effector cell sources for ADCC. In-vivo biological distribution research in mice carrying human tumor xenografts reveals that NEO-201 is preferentially accumulated in tumors rather than organ tissues. Single dose toxicity studies in non-human primates demonstrate the safety and tolerance of NEO-201 because the transient reduction of circulating neutrophils is the sole associated side effect observed.
