Breast cancer treatment: perspectives on the oncolytic virus

[Noteable]

Here is a new review appearing in "Frontiers" on oncolytic virus, including reovirus, in the treatment of breast cancer suggesting that multi-approach strategies - combining OVs and chemotherapy, radiotherapy, or immunotherapy - provide better therapeutic effects and show great potential in future approaches to breast cancer treatment.

March 20, 2024 - "Reovirus is a double-stranded RNA virus. Its replication is promoted in cells with an activated RAS pathway. The gain-of-function mutations, activating RAS signalling, are prevalent in cancers. Therefore, reovirus is a natural candidate for a therapeutic agent (45). Reovirus has oncolytic activity in vitro against multiple solid tumour types, including breast cancer (46). Reolysin is an unmodified wild- type oncolytic reovirus. In 2017, it received FDA approval for the treatment of metastatic breast cancer (46). Data from the Phase II trial for the treatment of advanced metastatic breast cancer showed that the combination of Reolysin and Paclitaxel significantly increased overall survival for about seven months (47). Clinical studies have demonstrated its effectiveness in combination with systemic anti-programmed cell death protein 1 (PD-1). In a murine breast cancer model, intratumoral reovirus increased PD-L1 expression on tumour cells, and combination reovirus/anti-PD-1 treatment improved survival by reducing Treg numbers and ameliorating tumour-specific cytotoxic T lymphocyte responses (48). Reovirus has also been used in combination with CD3-bispecific antibodies. Reovirus-induced IFN stimulated the recruitment of NK cells and reovirus-specific CD8+ T cells to the tumour site, while reovirus-specific effector T cells acted synergistically with CD3- bispecific antibodies, reducing the in vivo growth of several tumour types, including breast (46). Interestingly, this combination treatment was also effective against distant lesions that were not previously injected with reovirus. It suggests the possibility of using this therapy in case of metastatic disease (45). The advances in reovirus engineering have enabled the creation of oncolytic reoviruses that can antagonize inhibitory mechanisms within the TME. In particular, mutations in viral cell attachment protein σ1 gene, have been incorporated to prevent proteolytic cleavage and inactivation of σ1 by breast cancer-associated proteases". 

The advent of precision medicine calls for tailoring OVs to individual patient profiles. Developing personalised viral platforms could involve genetic modifications or viral engineering to enhance tumour specificity, replication efficiency, and immune activation while mitigating adverse effects. Advancements in identifying predictive biomarkers for treatment response remain also urgent. Identifying biomarkers associated with the efficacy of OVs can aid in patient stratification, ensuring targeted therapies for individuals most likely to benefit. 

An exciting frontier remains the synergy between OVs and conventional treatments like chemotherapy, radiotherapy, and immunotherapy. Exploring combination therapies can capitalize on their complementary mechanisms, potentially amplifying therapeutic efficacy and overcoming resistance. 

It is also crucial to find strategies that restore the tumour microenvironment and bolster anti- tumour immune responses. This includes interventions that regulate immune checkpoints, modulate cytokine profiles, or stimulate adaptive immune cells within the tumour milieu.

March 19, 2024 - Clinical evidence involving the checkpoint inhibitor pembrolizumab + chemotherapy demonstrates effectiveness in triple negative breast cancer (TNBC) pointing towards the benefit of adding an oncolytic virus, like ONCY's pelareorep, to further enhance the above effective doublet in both TNBC and ER+/HER2 negative breast cancer. "Patients were either treated with

"TNBCs have the highest levels of TILs, expression of immune evasion molecules in a tumor microenvironment such as PD-L1, and the most genomic instability compared with other breast cancer subtypes, which consequently makes it an immunogenic disease. Recently, results from several clinical studies showed that immune checkpoint inhibitors alone or in combination with a backbone (chemotherapy

Patholgists have recently made recommendations to include TILs in the pathology reports of early-stage TNBC worldwide, as it has the potential to inform clinicians and patients when they discuss treatment options. This biomarker would only require a visual evaluation by a pathologist looking through a microscope, meaning there are no additional costs associated with identifying the presence of

Employing biomarkers and surrogate endpoints in Orphan/Rare diseases, like in metatstatic breast cancer, result in smaller registration studies and more particularly opens the door for "Accelerated Approval" and smaller/quicker post approval confirmation studies.  Consequently it would appear that ONCY has asked for a meeting with the FDA to have them confirm the biomarkers

Isn't it funny how the leftwing mainstream media is now, suddenly, unanimously, "shocked" by our babbler-in-chief's disastrous debate performance.....when for 3 1/2 years they've been indoctrinating all the brainwashed as to how Biden is "sharp as a tack", and "runs circles around everyone around him"...5 .....the never-ending drumbeat of blatant lies

[Azzak34]

It was a horrific performance by JB no question and may well be indicative of a downward trend in competency for the job.  I imagine the guys are just busy reading the alleged newly released Epshtein documents where the orange man appears to be implicated in engaging in the worst kind of behavior possible. Have a read and let us know what you think. 

[Peladawn]

Not sure what you're reading, but one thing I can tell you for certain, is that there was even one iota, one tiny molecule, of misbehavior by "the most evil man in history" in any Epstein document, it would be front page and centre on every leftwing hack rag in the entire world.....the fact that Trump knew him as a fellow billionaire does not make him guilty of "the worst kind

[Peladawn]

Oh, and btw, Azzak, just out of curiosity, why exactly is it you like 20% inflation, thousands of unvetted illegal immigrants criminals walking freely across the southern border and some of them raping and murdering young girls, Mexican cartels making billions on sex trafficking young immigrant girls and boys, and smuggling deadly fentanyl pills that are killing thousands, Iran now building

[Azzak34]

For me I would like everyone would be even handed and consistent in everything they do/say.  I agree that the media would be picking on DT if there were hard evidence on this particular case..... however time will tell if there's any veracity to it. 

[Angler101]

If you would like everyone to be even-handed, then try being even remotely that way yourself....there's plenty of dirt to go after Biden about, but you and the rest of the kool-aiders always give him a free pass....sad.

[Azzak34]

I am not disagreeing with that. But again, you want a "cleanest dirty shirt in the hamper" debate. If your guy is dirty and their guy is dirty then maybe you have more in common than you think. 

[Angler101]

Azzak.....here are some facts for you to ponder....if you can actually wrap yoir head around them, then perhaps we can actually have a serious debate ....90% of journalists, by their own admission, are liberals (look up the polls) ....left leaning newspapers like the NYT and WSJ, and networks like CNN, MSNBC, etc. haven't endorsed a Republican candidate since the 80s .....they all started

[Azzak34]

The time it took you to write that could have been spent educating yourself.  I 100% agree the mainstream media is highlighting DTs alleged criminal activity and minimizing JBs, for me that is unequivocally true. But please stop putting your guy up as the savior of anything nevermind a country. He had 4 years to "drain the swamp" and he didn't. I will concede he did some good

Hey Azzak...I just watched an interview with the president of Finland, the lastest member of NATO...........he said there were only 3 members of NATO that were actually paying the required 2% of their gdp....since Trump came in a stirred things up, now there are 23.....NATO has received over $100 million dollars in payments since the Trump administration basically shamed members to finally start

It's a bit disingenuous to cherry pick information and I can't keep saying this if you're not reading it.... I think he did plenty of good things in office, that's not in question.  You didn't address the list of accusations you said I couldn't produce.  He did an interview where he said he wouldn't release the Epshtein files, go look that up. I suspect

[Peladawn]

Once again, I ask you, what makes you think Trump has anything to do with whether or not the Epstein files are released?.....whatever the h you're talking about was highly likely taken completely out of context, just like when Trump said he'd be a dictator on his first day of office, and since I've heard dozens of Democrats and just as many left wing hack pundits proclaim that "

[Azzak34]

Just stick Epshtein/ Trump release files in to YouTube amd you'll see what he said. Just have a look and tell me what you think. Yeah they definitely do take that out of context about the dictator and some of the left wing media are absolutely milking that for their own purposes. He still said he'd be a dictator on his first day though so that's still not great in a free society. 

[Peladawn]

You have got to be kidding me!....you think dictatorships last one day?....lmfao......you're not very good at picking up on sarcasm, are you....geez!.... but, not to change the subject, I just wanted to take this  chance to offer my deepest condolences to all the Democrats who are in mourning this evening because of the death of their last chance to take out their political opponent.....

Yeah but that's coming from his administration? Go back and find us an impartial, bipartisan source. I think I said previously that he had quite a few wins in his presidency. I don't even think he did a bad job legislatively for the US. It's who he his and what he's being accused of that concerns me!!!!

Yes it is coming from his administration.....but everyone knows that there was 1.4% inflation....gas was about half the price it is now....the border was under the best control it had been in decades.....no wars were erupting around the world...wages were rising at a rate far outpacing inflation....interest rates weren't exploding....jobs and industries were coming back to the US.....
