Immuron up 11% on encouraging Travelan data

Thinly traded nano cap Immuron Limited (IMRN +11.4%) is up in early trade on the heels of encouraging results from a Shigella challenge study of in non-human primates aimed at assessing the effectiveness of Trevalen for preventing dysentery.
12 juvenile rhesus monkeys were segregated into two groups, eight who received Travalen and four who received placebo prior to oral challenge with Shigella, a bacterial group that causes stomach cramps, fever and diarrhea.
All four monkeys in the placebo group developed acute dysentery within 24 – 36 hours of Shigella challenge.
Six of the eight monkeys in the Travalen group showed no signs of dysentery while two “displayed” signs of dysentery.
The results were reported by Bangkok, Thailand-based U.S. Armed Forces Research Institute of Medical Sciences, a laboratory of the Walter Reed Army Institute of Research.
The active ingredient in Travalen is hyperimmune bovine colostrum powder which binds to Enterotoxigenic E. coli, the most common cause of traveler’s diarrhea. It is also designed to reduce the risk of infection by other diarrhea-related bacteria like Shigella and Salmonella.

Zai Lab gets nod in Macau to sell Zejula for ovarian cancer

The company in-licensed the PARP inhibitor from TESARO (GSK +0.9%) in September 2016 for the China market.

Oklahoma judge blocks Teva’s $85M settlement

Teva Pharmaceutical Industries (TEVA -5.5%) continues to battle bad news. Bloomberg reports that a district court judge in Oklahoma will not approve the company’s $85M settlement over its role in the opioid epidemic there because AG Mike Hunter has not shown that the proceeds will go into the state’s treasury as mandated under a recent law.
Oklahoma lawmakers enacted the legislation after the $270M settlement with Purdue Pharma which will fund research and treatment programs instead of being deposited into the state’s coffers.
It appears unlikely, though, that the issue the TEVA settlement cannot be quickly resolved.

Halozyme on track for key data readout in Q4

Halozyme (HALO -0.2%reports that the target number of 330 overall survival (OS) events has been reached in the Phase 3 HALO-301 study evaluating lead candidate PEGPH20 for the first-line treatment of metastatic pancreatic cancer. The primary endpoint is OS.
Data maturity should be reached in mid-September, followed the announcement of topline results by December.

J&J and Colgate-Palmolive on short end of talc verdict

Bloomberg reports that a California jury has ruled in favor of plaintiff Patricia Schmitz, agreeing with her claim that talc products made by Johnson & Johnson (JNJ +1.3%) and Colgate-Palmolive (CL -0.5%) caused her cancer.

FDA approves Roche’s $90,000 lymphoma combination

The FDA has quickly approved a new antibody treatment for an aggressive form of lymphoma from Roche – costing in the region of $90,000 for a four-month course.
Polivy (polatuzumab vedotin-piiq) has been granted accelerated approval in combination with bendamustine chemotherapy and Rituxan (rituximab) (BR) for adults with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) who have received at least two prior therapies.
The disease is also targeted by the CAR-T therapies from Roche’s rivals Novartis and Gilead and Roche has opted to price its new regimen in line with these expensive cell therapies.
Polivy’s dosage is based on weight by Roche, which said a four-month course will cost $90,000 on average.
The price compares favourably with one-off shots of CAR-Ts from Novartis and Gilead that cost $373,000 and $475,000 respectively, but Polivy’s price could still make prescribers think twice, at least until further clinical data is available.
Accelerated approval allows for drugs to be licensed using early stage data from mid-stage clinical trials, based on the understanding that effectiveness is likely to be confirmed by findings of a larger trial.
But the FDA has granted approval based on findings of the Phase 1b/2 GO29365 study in people with R/R DLBCL who are ineligible for a haematopoietic stem cell transplant.
Results of the study showed that 40% – 16 out of 40 – of those treated with Polivy plus BR achieved a complete response, meaning no cancer could be detected at the time of assessment compared with 18% treated with BR alone.
The study also showed that 45% of people on Polivy plus BR achieved an objective response at the end of treatment compared with 18% of people treated with BR alone.
Of the people treated with Polivy plus BR who achieved a complete or partial response, 16 (64%) had a duration of response lasting at least six months compared to 30% of people treated with BR alone.
While this data suggests the drug continued to work for an extended period, it’s not the same as the overall survival figures that oncologists will be looking for when they decide what to prescribe.
The figures from Polivy also don’t compare favourably to Gilead’s Yescarta (axicabtagene ciloleucel), which according to figures announced at the end of last year produced a response rate of 83% after two years, with 58% of patients having a complete response.
However, Polivy has the advantage of convenience and will not require a drawn-out manufacturing process like Yescarta and Novartis’ Kymriah (tisagenlecleucel).
Being an antibody-based therapy, Polivy does not produce the extreme side effects seen with CAR-T either, such as neurotoxicity and cytokine release syndrome (CRS).
Roche said adverse reactions occurred in at least 20% of patients, and at least 5% more frequently in patients treated with Polivy plus BR compared to BR alone, and included low white blood cell count, low platelet levels, low red blood cell count, numbness, tingling or pain in the hands and feet, diarrhoea, fever, decreased appetite and pneumonia.
Polivy is a first-in-class anti-CD79b antibody-drug conjugate (ADC). The CD79b protein is expressed specifically in the majority of B-cells (an immune cell impacted in some types of non-Hodgkin lymphoma (NHL)), making it a promising target for the development of new therapies.
Polivy binds to CD79b and destroys these B-cells through the delivery of an anti-cancer agent, which is thought to minimise the effects on normal cells.
Polivy is being developed by Roche using Seattle Genetics ADC technology and is currently being investigated for the treatment of several types of NHL.

Minister says using generic CF drug is an option in Vertex Orkambi row

Vertex is coming under increased pressure to sign a deal with the NHS covering its Orkambi cystic fibrosis (CF) drug, with a government minister suggesting she would consider implementing laws allowing the NHS to use generic alternatives.
It’s more than three years since NICE said that Orkambi (lumacaftor+ivacaftor) is too expensive for the England’s NHS, sparking an increasingly bitter stand-off between health service officials, patients and the company.
Despite an improved offer from NHS England covering Orkambi last month, there has been no sign of the deadlock being broken.
Last week families of children with CF said they created a “buyers club” to import generic Orkambi from a manufacturer in Argentina.
In a debate in Parliament yesterday, MPs expressed outrage at this latest development, and junior health minister Seema Kennedy said the government has a “moral obligation” to explore all options to bring Orkambi to the UK market.
This includes a previously discussed move to implement a “Crown use” law that would allow the government to use a generic version of the drug at a vastly reduced price.
Continued negotiations between NHS England, NICE and Vertex is the “desired option” according to Kennedy.
“It is possible to go through the NICE appraisal process and reach an agreement with NHS England,” said Kennedy.
But in the absence of any progress Kennedy said she would explore other alternatives including Crown use, although MPs heard that putting these arrangements into place could take more than two years.
Sharon Hodgson, Labour MP for Washington and Sunderland West, said an agreement between Vertex, NICE, and the NHS would provide an “immediate outcome” that would get families their cystic fibrosis drugs.
Crown use remains an alternative only if negotiations continue to stall as it would take such a long time to implement, she said.
“Although that would be an option to look at if nothing else can be found, it would not give the families the drugs as quickly as we would like.”
In a separate development, the Association of the British Pharmaceutical Industry (ABPI) took the unusual step of praising NHS England for the flexibility it has shown during the negotiations.
In a blog post last week, the ABPI’s executive director for commercial policy, Richard Torbett, noted that Vertex is not a member of the trade body, and added that there is no information about the prices that are being discussed in the negotiations.
These are being kept secret for commercial reasons – but what is in the public domain is the structure of the deal NHS England has offered.
This would allow for a two-year managed entry period during which time the NHS would gather information about how Orkambi works in the real world.
If the drug performs well there is scope for a price increase, while if outcomes are below expectations its price could drop.
Torbett said: “It is clear that the structure of the offer represents exactly the sort of flexibility industry has been calling for some time.”
The ABPI has struck a new five-year pricing deal with the government for branded drugs that caps the overall spend each year, and rebates any excess back to the NHS.
A spokesperson for Vertex said the company welcomed the debate and “shared the urgency” of the speakers who wished to bring the drug to patients in England.
The spokesperson added: “We remain highly committed to the negotiations with NHS England and can confirm that a further meeting took place between Vertex and NHS England on Friday, 7th June. Our intensive work continues on a daily basis.
“In the absence of an access agreement, Vertex will continue to provide free medicines to patients who are the most seriously ill, based on objective clinical criteria, through our compassionate use programme.”
