Phase 1 Trial of SX-682, a CXCR 1/2 Inhibitor, in Combination With Standard of Care Treatment in Patients With Relapsed or Refractory Multiple Myeloma (RRMM)

This phase I trial tests the safety and side effects of SX-682 in combination with standard of care treatment carfilzomib, daratumumab-hyaluronidase, and dexamethasone in treating patients with multiple myeloma that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). SX-682 works by blocking certain sites on cells that suppress the ability of the immune system to destroy tumor cells. Blocking those specific sites allows other cells of the immune system to become "free" to kill tumor cells. Carfilzomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Daratumumab is in a class of medications called monoclonal antibodies. It binds to a protein called CD38, which is found on some types of immune cells and tumor cells, including myeloma cells. Daratumumab may block CD38 and help the immune system kill tumor cells, while hyaluronidase helps to deliver daratumumab to CD38-expressing tumor cells through a subcutaneous injection. Dexamethasone is in a class of medications called corticosteroids. It is known to kill myeloma cells and is also used to reduce inflammation and lower the body's immune response to monoclonal antibodies like dratumumab and help lessen its side effects. Giving SX-682 in combination with carfilzomib, daratumumab-hyaluronidase and dexamethasone may be safe and tolerable in treating patients with relapsed or refractory multiple myeloma

ObjectivePancreatic ductal adenocarcinoma (PDAC) is among the most immunosuppressive tumour types. The tumour immune microenvironment (TIME) is largely driven by interactions between immune cells and heterogeneous tumour cells. Here, we aimed to investigate the mechanism of tumour cells in TIME formation and provide potential combination treatment strategies for PDAC patients based on genotypic heterogeneity.DesignHighly multiplexed imaging mass cytometry, RNA sequencing, mass cytometry by time of flight and multiplex immunofluorescence staining were performed to identify the pro-oncogenic proteins associated with low immune activation in PDAC. An in vitro coculture system, an orthotopic PDAC allograft tumour model, flow cytometry and immunohistochemistry were used to explore the biological functions of cysteine-rich intestinal protein 1 (CRIP1) in tumour progression and TIME formation. RNA sequencing, mass spectrometry and chromatin immunoprecipitation were subsequently conducted to investigate the underlying mechanisms of CRIP1.ResultsOur results showed that CRIP1 was frequently upregulated in PDAC tissues with low immune activation. Elevated CRIP1 expression induced high levels of myeloid-derived suppressor cell (MDSC) infiltration and fostered an immunosuppressive tumour microenvironment. Mechanistically, we primarily showed that CRIP1 bound to nuclear factor kappa-B (NF-κB)/p65 and facilitated its nuclear translocation in an importin-dependent manner, leading to the transcriptional activation of CXCL1/5. PDAC-derived CXCL1/5 facilitated the chemotactic migration of MDSCs to drive immunosuppression. SX-682, an inhibitor of CXCR1/2, blocked tumour MDSC recruitment and enhanced T-cell activation. The combination of anti-PD-L1 therapy with SX-682 elicited increased CD8+T cell infiltration and potent antitumor activity in tumour-bearing mice with high CRIP1 expression.ConclusionsThe CRIP1/NF-κB/CXCL axis is critical for triggering immune evasion and TIME formation in PDAC. Blockade of this signalling pathway prevents MDSC trafficking and thereby sensitises PDAC to immunotherapy.

Triple-negative breast carcinoma (TNBC) is one of the most aggressive types of solid-organ cancers. While immune checkpoint blockade (ICB) therapy has significantly improved outcomes in certain types of solid-organ cancers, patients with immunologically cold TNBC are afforded only a modest gain in survival by the addition of ICB to systemic chemotherapy. Thus, it is urgently needed to develop novel effective therapeutic approaches for TNBC. Utilizing the 4T1 murine model of TNBC, we developed a novel combination immunotherapeutic regimen consisting of intratumoral delivery of high-mobility group nucleosome binding protein 1 (HMGN1), TLR2/6 ligand fibroblast-stimulating lipopeptide (FSL-1), TLR7/8 agonist (R848/resiquimod), and CTLA-4 blockade. We also investigated the effect of adding SX682, a small-molecule inhibitor of CXCR1/2 known to reduce MDSC trafficking to tumor microenvironment, to our therapeutic approach. 4T1-bearing mice responded with significant tumor regression and tumor elimination to our therapeutic combination regimen. Mice with complete tumor regressions did not recur and became long-term survivors. Treatment with HMGN1, FSL-1, R848, and anti-CTLA4 antibody increased the number of infiltrating CD4+ and CD8+ effector/memory T cells in both tumors and draining lymph nodes and triggered the generation of 4T1-specific cytotoxic T lymphocytes (CTLs) in the draining lymph nodes. Thus, we developed a potentially curative immunotherapeutic regimen consisting of HMGN1, FSL-1, R848, plus a checkpoint inhibitor for TNBC, which does not rely on the administration of chemotherapy, radiation, or exogenous tumor-associated antigen(s).

Targeted Deletion of CXCR2 in Myeloid Cells Alters the Tumor Immune Environment to Improve Antitumor Immunity

AbstractRecruitment of myeloid-derived suppressor cells (MDSC) into the tumor microenvironment (TME) contributes to cancer immune evasion. MDSCs express the chemokine receptor CXCR2, and inhibiting CXCR2 suppresses the recruitment of MDSCs into the tumor and the premetastatic niche. Here, we compared the growth and metastasis of melanoma and breast cancer xenografts in mice exhibiting or not exhibiting targeted deletion of Cxcr2 in myeloid cells (CXCR2myeΔ/Δ vs. CXCR2myeWT). Detailed analysis of leukocyte populations in peripheral blood and in tumors from CXCR2myeΔ/Δ mice revealed that loss of CXCR2 signaling in myeloid cells resulted in reduced intratumoral MDSCs and increased intratumoral CXCL11. The increase in intratumoral CXCL11 was derived in part from tumor-infiltrating B1b cells. The reduction in intratumoral MDSCs coupled with an increase in intratumoral B1b cells expressing CXCL11 resulted in enhanced infiltration and activation of effector CD8+ T cells in the TME of CXCR2myeΔ/Δ mice, accompanied by inhibition of tumor growth in CXCR2myeΔ/Δ mice compared with CXCR2myeWT littermates. Treatment of tumor-bearing mice with a CXCR2 antagonist (SX-682) also inhibited tumor growth, reduced intratumoral MDSCs, and increased intratumoral B1b cells expressing CXCL11, leading to an increase in activated CD8+ T cells in the tumor. Depletion of B220+ cells or depletion of CD8+ T cells reversed the tumor-inhibitory properties in CXCR2myeΔ/Δ mice. These data revealed a mechanism by which loss of CXCR2 signaling in myeloid cells modulates antitumor immunity through decreasing MDSCs and enriching CXCL11-producing B1b cells in the TME, which in turn increases CD8+ T-cell recruitment and activation in tumors.

Metastatic Castration-Resistant Prostate Cancer Overview Metastatic castration-resistant prostate cancer (mCRPC) is an advanced stage of prostate cancer that continues to grow and spread despite hormone therapy aimed at lowering testosterone levels. The term "metastatic" refers to cancer spreading to other parts of the body, such as the bones, lymph nodes, or distant organs, while "castration-resistant" indicates that the cancer no longer responds to treatments that reduce testosterone, a key driver of prostate cancer growth. mCRPC is typically more aggressive and challenging to treat than earlier stages of prostate cancer. The causes of mCRPC stem from genetic and environmental factors. Genetic mutations in the androgen receptor pathway can make cancer cells less dependent on testosterone, allowing them to thrive even under hormone-suppressing treatments. Environmental factors like diet, lifestyle, and exposure to certain chemicals may also contribute to the development and progression of prostate cancer. Symptoms of mCRPC often include pain in bones, fatigue, difficulty urinating, weight loss, and general weakness. As the cancer spreads, it can impair the function of other organs, depending on the site of metastasis. Diagnosis of mCRPC usually involves a combination of tests, including prostate-specific antigen (PSA) blood tests, imaging studies like CT scans, MRIs, or bone scans, and sometimes biopsies to confirm the spread and resistance to treatment. Treatment options for mCRPC are more complex and may include newer hormonal therapies (e.g., abiraterone, enzalutamide), chemotherapy (docetaxel or cabazitaxel), immunotherapy (e.g., sipuleucel-T), or targeted therapies such as PARP inhibitors. Bone-targeting therapies, radiation, and palliative care can also be used to manage symptoms and improve the quality of life. Treatment is typically tailored to the individual based on the extent of the disease and the patient health.

The agreement will allow Lupin to expand its gastroenterology portfolio in the Indian market. Credit: Orawan Pattarawimonchai/Shutterstock. Pharmaceutical company Lupin has announced a non-exclusive patent licence agreement with Takeda Pharmaceutical for the commercialisation of Vonoprazan tablets in India. The medication will be sold under the brand name Lupin’s Lupivon in the Indian market. Vonoprazan will be made available in 10mg and 20mg strengths. A potassium-competitive acid blocker (P-CAB), the drug differs from traditional acid suppressants such as proton pump inhibitors by offering rapid and complete proton pump inhibition from the first dose. Its longer duration of action also ensures effective control of nocturnal acid breakthrough, and it can be dosed independently of meals. See Also: Trilaciclib by G1 Therapeutics for Triple-Negative Breast Cancer (TNBC): Likelihood of Approval SX-682 by Syntrix Pharmaceuticals for Human Epidermal Growth Factor Receptor 2 Negative Breast Cancer (HER2- Breast Cancer): Likelihood of Approval The Drug Controller General of India (DCGI) has approved Vonoprazan for the treatment of gastric ulcers, reflux esophagitis and duodenal ulcers, and as part of the Helicobacter pylori eradication regimen. The agreement will allow Lupin to expand its gastroenterology portfolio in the Indian market, where acid peptic disorders (APD) are claimed to be highly prevalent. APDs encompassing gastroesophageal reflux disease (GERD) and peptic ulcer disease (PUD), impact a significant portion of the Indian population. GERD prevalence varies from 5% to 28.5%, while PUD affects approximately 8%. Older age, higher body mass index, non-vegetarian diets, consumption of tea or coffee and lifestyle choices such as smoking and alcohol intake are the risk factors for GERD. Lupin India Region Formulations president Rajeev Sibal stated: “We are very pleased to commercialise Vonoprazan, a novel treatment option for acid peptic disorders. “This is a further step in strengthening our gastroenterology portfolio and is in line with our commitment to introduce innovative medicines to address the unmet needs of our patients.” In November 2023, Lupin introduced the fixed-dose triple combination (FDC) drug , Vilfuro-G, to manage chronic obstructive pulmonary disease in India.

3-drug combo leads to 'unprecedented' response in pancreatic cancer models

Even among hard-to-treat solid tumors, pancreatic cancer is in a league of its own when it comes to survival mechanisms. Criminal profiling can be the key to catching a killer. The same could be said for immune system profiling, which appears to have helped scientists crack the code on one of oncology’s most notorious villains: pancreatic cancer. In a study published Dec. 30 in Nature Cancer, scientists at the University of Texas MD Anderson Cancer Center described how they systematically went about profiling the way pancreatic tumors keep a patient’s immune system from fighting their cancer. The researchers’ sleuthing led them to three proteins, which they then targeted in mouse models with a trio of immunotherapies. Their results showed an overall survival rate of up to 90% through the end of the year-and-a-half-long study—more than half the mice’s life span. The same cancer in people has a five-year survival rate of 11%. “As a human immunologist who has been involved in a lot of clinical trials, you’d be surprised that I was surprised that it worked so well, but I really was,” John Connolly, Ph.D., who is not involved in the research but is chief scientific officer at the San Francisco-based Parker Institute for Cancer Immunotherapy, told Fierce Biotech Research. Suppressing immune suppression Even among hard-to-treat solid tumors, pancreatic cancer is in a league of its own when it comes to survival mechanisms. Under normal conditions, the immune system regulates itself with checkpoints, suppression pathways that hold down the “off” switch on T cells that would otherwise attack a person’s own tissue. Pancreatic cancer is especially good at exploiting these pathways by keeping the suppression mechanisms turned on, ultimately “exhausting” the T cells in the area surrounding the tumors, also known as the tumor immune microenvironment. T-cell exhaustion is just what it sounds like: The cells no longer respond to foreign invaders, allowing cancer cells to proliferate undetected. Pancreatic tumors’ unparalleled ability to suppress T cells makes them highly resistant to immunotherapies. That includes checkpoint-inhibiting drugs like Merck’s PD-1 inhibitor Keytruda and Bristol Myers Squibb's Yervoy, a CTLA-4 inhibitor, on their own or in combination. “Over the last 20 years, the field has tried many, many different agents to enhance the therapeutic strategies for this disease,” Ronald DePinho, M.D., senior author of the study, said. The statistically significant survival benefits seen in both mice studies and human trials thus far aren’t enough to make a meaningful difference in the clinic, he added. But perhaps it was a matter of hunting down and neutralizing the right combination of the right checkpoints, DePinho’s lab reasoned. That would require a clear profile of how pancreatic cancer was impacting the immune system—in other words, its immune “fingerprint,” as Connolly described it. To find that fingerprint, Pat Gulhati, M.D., Ph.D.—a postdoc in DePinho’s lab—set about cataloguing all the immune checkpoint proteins that were expressed in exhausted T cells found in the tumor immune microenvironment of mice with pancreatic cancer. The researchers also took stock of the ones in both treated and untreated samples from patients to make sure their findings were clinically relevant, with particular attention to the ones that showed up in highly resistant disease. In both samples, the researchers found that in addition to PD-1 and CTLA-4, the checkpoint proteins TIM3, 41BB and LAG were also expressed. They then enlisted their mouse models in multiarm studies with antibodies designed to target these proteins along with others they found in their search. Similar to what had been seen in humans, neither PD-1, TIM3 or CTLA-4 inhibition improved survival. But anti-LAG3 and agonistic 41BB antibodies individually extended the mice’s survival time by about 20% to 30% compared to controls. “And—as expected because mechanistically they worked quite differently—the combination of the two had additive effects,” DePinho explained. The dual therapy more than doubled their survival time. Third drug's the charm But despite living twice as long as untreated models, the two drugs weren’t enough to keep the mice from succumbing to the disease. The researchers wondered whether they could improve the numbers with a third agent. For that, they turned to CXCR2, a protein that recruits myeloid-derived suppressor cells, or MDSCs, to the tumor immune microenvironment. Summoning MDSCs is another nifty trick up cancer’s sleeve. While normal myeloid cells—which include neutrophils and monocytes—act against foreign invaders, MDSCs have suppressive activity. Cancerous tumors activate them so they turn off T cells. And because they aren’t susceptible to immune checkpoint inhibitors, they’re a common route of treatment resistance. Like the two-drug combo, treating the mice with a CXCR2 inhibitor called SX-682 once again boosted their survival time by about 30% to 40%. Encouraged, the researchers then tried the three agents together. After 540 days, all but one of the 10 mice in a group with a highly virulent pancreatic cancer were still alive. Other groups with tumors grown from different cell lines had overall survival rates of around 70%. In models with multifocal, spontaneously arising tumor—a particularly aggressive form—the survival rate was 20%. None of the animals alive at the study’s end had any signs of cancer. “These were unprecedented cures seen in a very virulent mouse model of this disease,” DePinho said. Cell sequencing and immune profiling confirmed that drugs had indeed induced a potent immune response, overcoming suppression by the tumors. The study’s models were especially strong because the researchers made an effort to ensure that the immunosuppression patterns they saw in mice were the same as those in samples from human patients, Connolly said. “They created a nice resistance model that accurately reflected how resistance works in a human,” he explained. “Then they used advanced immunophenotyping and analytical techniques to really dive in and come up with a fingerprint of how resistance is working.” Speeding to the clinic All three of the drugs used by the researchers are being studied separately in early-stage clinical trials. Bristol Myers Squibb’s LAG3 inhibitor relatlimab, which is already FDA approved as part of a combination treatment for metastatic melanoma, is one of the drugs being studied in the National Cancer Institute’s MATCH screening trial for solid tumors. Pfizer’s utomilumab, a 41BB agonistic antibody, showed a favorable safety profile in a phase 1 pancreatic cancer trial. And the CXCR2 inhibitor SX-682, developed by Syntrix, is in a phase 1 trial for pancreatic cancer with Bristol Myers Squibb’s Opdivo. Combined with the results of their study, the work already being done with the agents warrants speeding along the process to trying them together in humans, DePinho said. “I think there’s as much preclinical proof-of-concept one could glean from looking at human specimens, which showed that the targets are there and that they correlate with clinical outcomes,” he said. “And the mouse model, which is a very faithful mouse model of the human disease, shows rather striking and encouraging results.” Connolly agreed. “There’s a lot of good mouse studies out there, but you really want to translate this to the clinic for it to be meaningful to patients,” Connolly said. “We really want to see that clinical trial get out there.” Combos galore Given that only 20 percent of the most aggressive tumors were cured with the triple combination, there’s also potential to try the combo with different agents that work against different suppression mechanisms. DePinho is particularly intrigued by the possibility of testing them with KRAS inhibitors, which have shown signals of efficacy both preclinically and in early stage clinical trials. “With the advent of KRAS inhibitors, there is now going to be an opportunity to combine KRAS inhibitors with immune modulatory agents,” he said. “Based on our work, I would put at the top of the list anti-LAG3 and agonist 41BB or the CXCR2 inhibitor.” Connolly again agreed, noting that the concept makes sense for outsmarting drug resistance. “You want to try to add therapeutics that don’t share a mechanism of resistance,” he said. “The tumor may be able to escape the immune system, but it’s very difficult to escape the immune system and KRAS suppressors.” In general, the researchers’ approach is ideal for designing multidrug therapies, Connolly said. “Ron’s lab gives you a roadmap on how to make a combination therapy,” Connolly said. “Find the fingerprint of suppression, find the mechanism of resistance and attack that mechanism.”
