Bexion Early-Stage Cancer Drug Being Hailed as Game Changer


Bexion Pharmaceuticals is not a household name as far as drugmakers go. But, this week the company and its investigational cancer treatment, BXQ-350, is receiving lots of mainstream media coverage as a potential game-changer.
BXQ-350 is a formulation of a synthetically produced, human lysosomal protein, Saposin C (sphingolipid activator protein, or SapC), and the phospholipid dioleoylphosphatidylserine (DOPS). It is being developed as a first-in-class treatment for solid tumors and gliomas.
In animal models, the effect of BXQ-350 has been significant. USA Today reported this week that the medication fused to the walls of cancer cells in mice and killed them – without harming healthy cells. As animal research continued on various cancer types, the results seemed to be the same – death for the cancer cells.
As development progressed on the drug, the newly-formed Bexion Pharmaceuticals began to receive financial support from a number of agencies, including the National Institutes of Health, and the National Cancer Institute. The drug was finally cleared for human testing and Bexion wasted little time.
Earlier this year at the American Society for Clinical Oncology, Kentucky-based Bexion unveiled preliminary data of a Phase Ia trial in a poster presentation that revealed some promising results. Of the 17 patients, nine with Glioblastoma Multiforme and eight with other solid tumors, the company saw a positive response in seven patients after 113 days. One patient with appendiceal carcinoma saw a partial response and six patients showed signs of disease stability. Of those six, one was a high-grade glioma patient who showed stable disease signs for greater than 19 months, according to company data.
The glioma patient is Bob Rulli, a retired airplane engine designer. He is the focus of the USA Today article that is blazing its way across social media platforms. Rulli has already lived with his glioblastoma multiforme for nearly five years. Average life expectancy is less than two years. Rulli has been on the Bexion treatment for 19 months. His cancer hasn’t been eliminated, but the tumor has proven to be stable during that time – meaning it’s not gotten worse. That wasn’t the really remarkable news though. In May Rulli underwent an MRI and the scan showed what appeared to be dead tumor cells. Bexion and other medical officials were quick to note that Rulli is something of an outlier when it comes to drug response, particularly with glioblastoma multiforme.
At ASCO, the company also shared additional good news about BXQ-350. Not only did those seven patients have positive responses to the drug, there were also no dose-limiting toxicities observed and no treatment-related serious adverse events. Bexion now has its eyes on further clinical testing. Ray Takigiku, Founder and chief executive officer of Bexion, said the company is enrolling patients with solid tumors and gliomas in Phase Ib testing and is eying a Phase II trial in adults. Bexion is also initiating efforts for a Phase I trial in pediatric patients, Takigiku said in a statement following ASCO.
To move forward though, the company will need to raise additional revenues. Bexion executives told USA Today that the company has about $40 million, but will need to raise significantly more to advance testing for BXQ-350.
Rulli has continued with his treatments and continues to defy the odds.

Manufacturing problems leave Jazz with ‘extremely limited’ Erwinaze supply


  • Jazz Pharmaceuticals continues to grapple with manufacturing complications that have crimped the supply and sales of its blood cancer drug, Erwinaze.
  • Though second quarter Erwinaze revenue rose 20% year over year, Jazz leadership noted inventory is “extremely limited” due to issues at the drug’s single-source provider, Porton Biopharma Limited. In March 2016, the Food and Drug Administration hit PBL with a Form 483 detailing significant violations in the way the company was manufacturing finished pharmaceuticals and active pharmaceutical ingredients.
  • Since then, PBL has received a warning letter, another Form 483 and ruffled feathers with U.K. regulators. While the production problems have made Erwinaze vulnerable to supply disruptions, Jazz reiterated guidance this month that net 2018 sales of the drug will be between $190 million to $220 million.

The violations at PBL are affecting more than just the production of Erwinaze (asparaginase Erwinia chrysanthemi). On a recent earnings call, Jazz executives said the precarious inventory position is weighing on commercialization too.
“Knowing we’ve not had sufficient product supply to meet all demand, we have chosen to reduce our promotional efforts around that,” CEO Bruce Cozadd said on the call. “So we don’t want to go out and create demand, particularly in new patient populations, that we then can’t satisfy.”
Jazz also explained that educational activities — especially those concerning Erwinaze’s efficacy in adolescents and young adults — have been gummed up.
“We’d like to be getting that story out more,” Cozadd said.
The concern is understandable, given Erwinaze is Jazz’s second biggest brand, behind the narcolepsy and cataplexy drug Xyrem (sodium oxybate). Jazz is walking a fine line as well, since it licenses the drug from PBL. That agreement expires in December 2020, though it could be lengthened through five-year extensions provided that neither company terminates the deal by December 2018.
“We cannot predict whether the term of the agreement will be extended or, if extended, the terms of any such extension. If the agreement is terminated, we will lose our license to sell Erwinaze in any market after December 2020, except under specified terms for a post-termination transition period,” Jazz wrote in its most recent quarterly filing with the Securities and Exchange Commission.
The manufacturing problems holding down Erwinaze, along with generic competition threatening Xyrem, could be weighing on investor optimism. Shares of the biotech fell 3.7% following its second quarter earnings report despite almost 27% year-over-year revenue growth.

Trump administration sinks teeth into paring down drug prices, on 5 key points


Three months after President Donald Trump announced his blueprint to bring down drug prices, administration officials have begun putting some teeth behind the rhetoric.
Many details have yet to be announced. But experts who pay close attention to federal drug policy and Medicare rules say the administration is preparing to incrementally roll out a multipronged plan that tasks the Centers for Medicare & Medicaid Services (CMS) and the Food and Drug Administration with promoting competition, attacking the complicated drug rebate system and introducing tactics to lower what the government pays for drugs.

Mark McClellan, director of the Duke-Margolis Center for Health Policy in Durham, NC, and a former CMS administrator, said that although none of the initial steps has “fundamentally transformed drug prices,” there is “a lot going on inside the administration.”
Two HHS officials who are rolling out the plan, Dan Best and John O’Brien, described their efforts to Kaiser Health News not as a public relations strategy but a push to reform the system.
“This administration is trying to go after root causes” of high drug prices, said Wells Fargo analyst David Maris.
But others are not so optimistic.
Ameet Sarpatwari, an instructor in medicine at Harvard Medical School in Boston, said policies the administration has rolled out thus far “alone will not translate into meaningful cost savings for most Americans.”
Broadly, the strategy falls under a handful of steps:
1. Attacking The Rebates
Health and Human Services Secretary Alex Azar has said Americans “do not have a real market for prescription drugs” because drug middlemen and insurers get a wide range of hidden rebates from drugmakers, but those savings may not be passed on to consumers or Medicare. In July, the administration submitted a proposed rule that could change the way rebates are handled.
Details of the proposal have not been made public. But O’Brien, a deputy assistant secretary at HHS, explained during a recent conference on federal drug spending sponsored by the Pew Charitable Trust: “You don’t have to use market power to get rebates, you can use market power to obtain discounts, to actually lower the price of the drug on the front end.”
Umer Raffat, an investment analyst with EverCore ISI, said “it’s not clear [that drug prices are going down]” but the “rebate structure is changing.”
2. Bringing More Negotiation To Medicare
This week, CMS Administrator Seema Verma announced that Medicare Advantage insurers can use a step-therapy approach to negotiate better prices for Part B drugs — those administered in hospitals and doctors’ offices. These private plans will be allowed to require patients to first select the least expensive drug before stepping up to more costly drugs if the original medications aren’t working.
The administration is also looking at ways to introduce more competition into Part B drug purchasing. That idea was mentioned deep inside the annual Medicare outpatient payment rule released last month.

Peter Bach, director of Memorial Sloan Kettering’s Center for Health Policy and Outcomes in New York, pointed to the possible introduction of a competitive purchasing program in which a firm negotiates with drugmakers to buy their drugs and then sells them to the doctors and hospitals that will administer the medications. Bach said that helps ensure that hospitals and doctors can’t make more money by prescribing more expensive drugs.
Currently, Medicare pays the average sales price plus 6 percent to doctors or hospitals when they purchase drugs, a pricing mechanism that can benefit the providers if the drug costs go up. If there were a third party buying the drugs, it would “have a huge effect,” Bach said.
3. Paying For Value
Trump’s blueprint calls for CMS to encourage “value-based care” to lower drug prices, shifting from paying a set fee for drugs to basing payments on how well the patient does on them.
Louisiana’s Medicaid program could show the way. The state is working with CMS to explore a subscription-based model to pay for hepatitis C medicines. Louisiana would pay a fixed price to a drug manufacturer that would then get unlimited access to treat patients enrolled in Louisiana’s Medicaid program or in prison.
The program would move “from a big payment upfront to paying less over time based on actual outcomes,” said McClellan, who also serves on the boards of health care giant Johnson & Johnson and insurer Cigna.
CMS also approved a Medicaid waiver from Oklahoma in June. Medicaid programs are allowed to negotiate drug prices. Oklahoma’s plan would expand that to negotiate additional prescription price reductions based on value-based purchasing agreements.
Still, CMS’ recent rejection of a related Massachusetts proposal makes it difficult to believe negotiating drug prices will really happen, said Sara Rosenbaum, a professor of health law and policy at George Washington University.
That proposal would have allowed Massachusetts’ Medicaid program to choose drugs based on cost and how well the medicines work.
“They have been very good and quite careful with their [Medicaid] program and so why not let them try this?” Rosenbaum said.
4. Tackling Foreign Drug Costs
Pharmaceutical makers often sell their drugs at substantially lower prices in many foreign countries than they do in the United States. Trump emphasized in May that “it’s time to end the global freeloading once and for all,” saying U.S. consumers were paying part of the cost of the medicines that patients in other countries use.
He directed US Trade Representative Robert Lighthizer to address the situation. Lighthizer’s office declined to comment.
When Sen. Todd Young (R-Ind.) asked during a Senate health committee hearing in June whether trade agreements with other countries should be used to “level the playing field,” Azar’s response was swift: “We absolutely believe we should be using our trade agreements to get them to pay more even as we have our job to pay less.”
Avalere Health President Matt Brow, who has been involved in talks with the administration, said it’s clear the focus on overseas pricing isn’t going away and the administration is “talking a lot about how to get the president what he wants.”
5. Increasing Competition

FDA Commissioner Scott Gottlieb has become the Trump administration’s lead proponent for increasing competition among drugmakers.
Competition resonates with Americans “because people see it every day in their experience in Costco and other places,” said Rena Conti, an assistant professor at the University of Chicago.
Gottlieb has announced plans to bolster the use of generic drugs and an “action plan” to encourage the development of biosimilars, which are copycat versions of expensive biologic drugs made from living organisms.
And to combat anti-competitive behavior in the market, Gottlieb said the FDA has passed along information to the Federal Trade Commission and hinted at potential action to come: “I think we’ve handed them some pretty good facts.”

Alnylam may open lower on narrower label than hoped, says Piper Jaffray


Piper Jaffray analyst Edward Tenthoff noted that the FDA approved Alnylam’s Onpattro with a label that restricts treatment to patients with polyneuropathy, versus inclusion of the broader cardiomyopathy population. The shares, which remain halted, may open lower given that the label is narrower than he anticipated, Tenthoff tells investors. However, he believes superior efficacy and first-to-market advantage will help Alnylam rapidly penetrate the orphan hATTR polyneuropathy market with premium pricing. Tenthoff keeps an Overweight rating and $160 price target on Alnylam shares, which were up $3.13, or 3.3%, at $97.38 when they were halted.
