BioMed Valley Discoveries announces presentation of early clinical activity of first-in-class cancer therapy ulixertinib at 2017 ASCO annual meetingMay 26, 2017
Bob Li, MD, MPH, a medical oncologist at Memorial Sloan Kettering Cancer Center, will present scientific data from a multicenter Phase I/IIa clinical trial supporting further clinical development of ulixertinib. The clinical trial, sponsored by BioMed Valley Discoveries, was designed to assess the safety of ulixertinib and preliminary anti-tumor activity in patients with advanced solid tumors.
The research abstract was awarded “Best of ASCO” status, a designation reserved for studies that reflect the foremost research and strategies in oncology that will directly impact patient care.
Ulixertinib targets ERK, the terminal kinase of the mitogen-activated protein kinase (MAPK) signaling pathway, which is involved in cell growth, proliferation, and survival. Mutations in components of the MAPK pathway are present in more than a third of all human cancers.
“This is the first ERK inhibitor to advance this far in the clinic,” said Dean Welsch, PhD, project leader and Executive Director of Translational Sciences and Head of Pharmacology at BioMed Valley Discoveries. “We have reached a key milestone in the development of this compound as a single agent. In the future, we plan to test this agent alone as well as in combination with drugs that target the same and other pathways.”
The MAPK signaling pathway is one of the most well-studied pathways in human biology. The MAPK pathway acts like an intracellular relay race: the first component, RAS, activates RAF, which activates MEK, which activates ERK, which finally flips the switches that enable a cell to grow, proliferate, and survive. In many types of cancer, this race never ends, causing cells to grow out of control. Because of its importance in cancer, the MAPK pathway has been the focus of drug discovery for more than 15 years.
While no compounds have effectively targeted RAS in the clinic, drugs designed to inhibit RAF or MEK have improved clinical outcomes for metastatic melanoma and other tumor types. However, the majority of patients given these targeted therapies eventually develop resistance to the drugs and a reoccurrence of disease. Because ERK resides at the end of the relay, ERK inhibition may provide an effective treatment that is less susceptible to acquired drug resistance.
The first part of the clinical trial entailed a dose escalation study in 27 patients. This part established a recommended Phase II dose of 600 milligrams twice-daily. The second part of the trial involved a cohort expansion in 108 patients with specific mutations and tumor types, including BRAF or NRAS mutant melanoma and other BRAF or MEK mutant cancers.
“Previous work targeting the MAPK pathway has largely centered around the most common alteration to the BRAF gene known as the V600 mutation,” said Welsch. “Our study was unique because we didn’t just include patients who had that one mutation, but also those who harbored other atypical BRAF mutations that activate that same pathway. Our plan is to help patients whose tumors contain these mutations and who do not currently have any approved treatments. We are also to excited to follow up this successful trial with additional ones testing our ERK inhibitor in combination with other agents."
Overall, the treatment appeared to be safe and well-tolerated. The most common adverse events were rash (49%), diarrhea (47%), fatigue (41%), and nausea (37%), side effects comparable to those seen with MEK inhibitors targeting an upstream part of the pathway.
In addition to three patients with partial responses (11%) to ulixertinib during dose escalation, an additional eleven partial responses (13%) were observed during the expansion part of the trial: one patient with melanoma resistant to BRAF/MEK inhibitors, three patients with NRAS mutant melanoma, two patients with BRAF mutant lung cancers, one patient with BRAF mutant glioblastoma multiforme, and four patients with atypical BRAF mutations.
BioMed Valley Discoveries already has several investigator-initiated trials underway to look at new indications. It also plans to assess whether ulixertinib may be effective in novel combination therapy regimens, and in specific genetic backgrounds that accompany acquired resistance.
Ulixertinib received FDA Fast Track designation in September 2015.

Bacterial biosurgery shows promise for reducing the size of inoperable tumorsAugust 13, 2014
Kansas City, MO. — Deep within most tumors lie areas that remain untouched by chemotherapy and radiation. These troublesome spots lack the blood and oxygen needed for traditional therapies to work, but provide the perfect target for a new cancer treatment using bacteria that thrive in oxygen-poor conditions. Now, researchers have shown that injections of a weakened version of one such anaerobic bacteria — the microbe C lostridium novyi — can shrink tumors in rats, pet dogs, and a human patient.
The findings from BioMed Valley Discoveries and a nationwide team of collaborators demonstrate that C. novyi-NT, a version without the ability to make certain toxins, can act as a new type of “biosurgery” to eat away tumors in hard to reach places. The bacteria excise tumor tissue in a precise, localized way that spares surrounding normal tissue. The study — which represents a new take on an approach first attempted a century ago — indicates that further testing of this agent in selected patients is warranted.
“We have encouraging signs that this bacteria could be used to treat certain inoperable tumors, and that could give hope to some patients who don’t have any other options,” said Saurabh Saha, M.D., Ph.D., a longtime cancer researcher at BioMed Valley Discoveries and senior author of the study. “But we are still in the early stages, and need to further assess the safety and efficacy of the treatment, as well as explore how well it works in combination with other cancer therapies.”
The study was published August 13, 2014, in Science Translational Medicine.
The idea of using bacteria to combat cancer dates back to the 1890’s, when cancer researcher William Coley noticed that some patients who developed postsurgical infections went into remission or were even cured of their disease. Despite the approach’s initial promise, progress was slow for the next century.
Over a decade ago Bert Vogelstein, M.D., a cancer researcher at the Johns Hopkins School of Medicine and one of the study co-authors, tested a number of microbes before identifying a particularly promising one called Clostridium novyi. Because C. novyi is exquisitely sensitive to oxygen, it would grow inside the oxygen-poor core of tumors but stop once it reached healthy tissue. In previous studies, Vogelstein and his colleagues tamed the bacteria further by removing its ability to make toxins and then injected it intravenously into laboratory animals. Though the bacterial treatment had dramatic effects in a third of the mice and rabbits, no complete responses were seen in dogs with naturally occurring cancers.
Dr. Saha and his colleagues at BioMed Valley Discoveries wondered if this failure was due more to the route of administration than to the therapy itself. One issue with intravenous delivery is the small proportion of spores that actually make it to the tumors. The researchers hypothesized that injecting the spores directly into tumors would not only overcome this problem, but might also trigger localized inflammatory and immune responses against tumor cells.
The researchers tested C. novyi-NT via directly injecting the bacteria into tumors in pet dogs with naturally occurring cancers and whose owners volunteered them for the trial. Each dog received between one and four cycles of the new treatment, consisting of a single injection of 100 million spores directly into the target tumor. Of sixteen dogs evaluated after treatment, three had significant shrinkage of their tumors and three had tumors that were completely destroyed.
The next step was to attempt the treatment in humans. The first patient to enroll in this Phase I investigational study was a 53-year old woman with retroperitoneal leiomyosarcoma whose disease, despite eight rounds of chemotherapy and radiation, had spread to her liver, lungs, abdomen, upper arm, and shoulder. The researchers injected 10,000 spores into the patient’s metastatic right shoulder tumor. Within days, CT scans and biopsies demonstrated that the bacteria had infiltrated the tumor and had begun destroying tumor cells. Weeks later, a follow-up MRI showed that a significant amount of tumor had been destroyed. As a result of treatment, the patient’s shoulder pain subsided and she was able to move her arm again.
Studies in other patients are currently underway at multiple sites to test the safety and efficacy of this new approach. Though these results are preliminary, the researchers believe that C. novyi-NT could potentially become part of a new arsenal of immunotherapies that prime a patient’s immune system to fight off cancer.
“Earlier pre-clinical studies showed that in the process of destroying cancer tissue, C. novyi-NT generates a potent innate immune response which also contributes to the localized tumor destruction,” said Dr. Saha. “The hope is that C. novyi-NT will be a useful adjuvant to the new immune checkpoint inhibitors that can block the ability of tumors to evade a host mediated immune response. It will be interesting to see if a combination of the two approaches could destroy tumors not just at the injection site, but also at any other sites where the cancer may have spread to throughout the body.”
