'WuXi Advanced Therapies is one of the top 3 cell and gene therapy CDMOs in the world'

Plutonian,

I'm sure you appreciate this very well already, but by simply following the partners we know about it's surprising how many times BMS crop up with the funding and an option.

Hugely wealthy companies and I suppose they have to play the field to be sure of future success with something, but certainly from my digging around BMS seem to crop up most.

It does suggest that at some future point we will be hearing a lot more about them, but whether they are in with the late stage / preparing for commercial supply groups which OXB have told us about? Time will tell.

You nearly had me there PB ;)

Oxford BioTherapeutics is a different company.

... but we know we are developing CART-ddBCMA for Arcellx in collaboration with Kite (a Gilead company).

We really do have a finger in every pie!

[harry s truman] 11/5/2024 10:14

PB,

If we have anything with Kite then it's on the secret list. I'll not say it's impossible, but we do know it's very difficult to change vector mid trial stage and even harder once approved.

As of the results we had 35 current partners.

With what they have told us over previous years we only really have a clue about 14 of them:-

Arcellx = CAR-T ongoing with a pivotal P2 trial
AZ = Obviously the covid vaccine has gone, but they wanted to continue the contract?
Beam Therapeutics = CAR-T clinical data H2 this year.
Bioverative = Bought by Sanofi who deprioritised (dropped the programme).
BMS (Juno) = Mega deal at least 6 programmes. I have my guesses but OXB never say.
Boehringer Ingelheim = Cystic Fibrosis. Very exciting. Human trials start this summer.
Cabaletta Bio = Biggest partner we know of with 9 programmes. Data from 2 in H1.
CARGO Therapeutics = Partner with CD22 CAR-T data in H1 '25.
Homology = ran out of money / no longer exists.
Immatics = Partner on TCR-T
Immune Design = Bought by Merck who said they would continue but it's secret.
Kyverna = Partnered on KYV-101 which is ongoing.
Novartis = Brilliant commercial partner for OXB + multiple T-Charge to come.
Orchard Therapeutics = Using LentiStable in P3 + our vector in P2.
Oxford University = Lassa fever + MERS + likely Malaria + Junin vaccines.
Sardocor = newest deal we know of - heart disease technology transfer.
Sio/Axovant = ran out of money / no longer exists.

So 14 of those are current which meant that a fortnight ago they had another 21 partners where we have no idea who it is. Could one of the 21 be Kite? Yes, but if they have a working vector they are already established with then they are unlikely to change that unless there is a major problem. Could they be trialling LentiStable (like Orchard) to improve a non-OXB process? Absolutely.

But I do enough wild guessing about things where we actually know names...

pharmaboy3,

That is Gilead's Tecartus (a reworked version of Yescarta for other indications). It has been marketed for some while now. The approval is just for some labeling amendments.

We already have 3 approved CD19 directed CAR-T:
* Kymriah - Novartis
* Yescart/Tecartus - Gilead
* Breyanzi - Bristol Myers Squibb

There are several more in the clinic now.

[harry s truman] 11/5/2024 09:44

takeiteasy,

There is no fixed value. It all depends upon the market.

FTSE100 are obviously the top 100 most valuable companies by market cap. If at any quarterly review another company from the top of the FTSE250 (the division below the 100) has grown in market cap to be the 90th most valuable company or above, then they will get promoted and boot the ones they have replaced down into the FTSE250.

The FTSE250 sat beneath the FTSE100 combine together to make the FTSE350.

On any quarterly review, if OXB is the 325th most valuable company or better by market cap at close of the date, then they will be promoted.

When they dropped below 376th place on the back of the economic disaster we know as the pandemic, then they were out.

Last time we were promoted from FTSE Smallcap into the FTSE250 the economy was much better and OXB needed to be £7 something to get promoted. Right now London values aren't there and at the moment just under £6 would do it at the end of this month.

[pharmaboy3] 11/5/2024 07:51

I'm not sure if OXB still has a manufacturing deal with Kite,but apparently, they have FDA approval Making it a third car t alongside Yescarta and KymriahHTTps://www.fda.gov/vaccines-blood-biologics/cellular-gene-therapy-products/tecartus

Then, beyond 400p, thoughts of 350/250 inclusion will begin to beckon.

Has anyone here calculated more precisely what the entry level 250 equates to share price wise here....

HIC Demonstrates Promising Separation of Deaminated and Non-Deaminated AAV Capsids (ASGCT 2024)
Published on: May 10, 2024
Feliza Mirasol

Studies conducted by a team at Oxford Biomedica demonstrated that HIC can be used to effectively separate non-deamidated capsids from deamidated capsids.

In a presentation given at the American Society of Gene and Cell Therapy’s (ASGCT’s) 27th Annual Meeting, Alex Meola, associate director of AAV Downstream Process Development at Oxford Biomedica, shared results from a study he and his team conducted in which theydemonstrated that hydrophobic interaction chromatography (HIC) can be used to separate non-deamidated capsids from deamidated capsids. The ASGCT annual meeting is occurring on May 7–11, 2024 in Baltimore, Md.

Meola emphasized how the focus on post-translational modification of capsid proteins of the adeno-associated virus (AAV) is growing in the process and analytical development space for gene therapies. The industry has been particularly focusing on how the deamidation of capsid protein from viral protein 1 (VP1)-specific residues, including the N57 domain, is linked to a loss of in-vivo potency (1).

“Temperature, pH, and storage time have been identified as key factors causing this phenomenon,” Meola. “In our quest at Oxford Biomedica—to try and resolve this—we have a static binding capacity residence screening protocol that we run where we look at a variety of different residents. In this case, we decided to look at salt-tolerant residents,” he stated.

Besides process control to prevent deamidation, Meola’s team hypothesized (2) that extrusion of VP1 and deamidation of N57 are related phenomenon and result in generating empty, partial, and full capsids, which significantly influences the ability of the anion exchange chromatography (AEX) process. AEX’s ability to remove empty capsids and deliver functional AAV is thus compromised.

Meola noted that charge-driven separation techniques have not provided the resolution required to differentiate between deamidated and non-deamidated capsid species. Because of this, his team highlighted novel approaches that can be applied to the AEX process to address the complex challenge of removing both empty capsids and deamidated intact capsids. “Controlling strategies in the upstream and downstream processes should be studied and defined at the early stage of process development to limit onset of deamidation in order to minimize product related impurities and loss of vector functionality,” Meola stated.

One of the team’s first approaches was to use HIC to separate distinct peaks with near baseline resolution. After separation, each peak was isolated and individually reprocessed with AEX. “Surprisingly, we discovered that HIC resolved two different species of AAV capsids with near baseline resolution. Each species was reprocessed on AEX, and all product quality attributes were assessed for the intermediate peaks that were generated. We found that the capsids that were more hydrophobic were also more negatively charged,” he explained.

Furthermore, data from liquid chromatography–mass spectrometry analysis demonstrated that the more hydrophobic and more negatively charged capsids exhibited significant levels of VP1-specific N57 deamidation, which has been linked to a loss in gene expression. It was demonstrated, therefore, that the extrusion of VP1 exposes the hydrophobic phospholipase A2 domain on the VP1 unique region, a phenomenon that would make VP1 N57 residue exposed to solvent and thus susceptible to deamidation.

The team was thus able to demonstrate that HIC can be a useful method to separate non-deamidated capsids from deamidated capsids. Meola also stated that the team is working on a novel, patent-pending method to remove deamidated species while simultaneously enriching full capsids on the AEX process.

The STING agonist IMSA101 enhances chimeric antigen receptor T cell function by inducing IL-18 secretion

[boadicea] 10/5/2024 14:18

Relatively quiet since the last of the million-plus days on 7th May.
However, the price remains fairly steady; no large retrace - implying that buyers are waiting to take up trader's profit selling. It has not yet formed a significant characteristic pennant and may not be given time to do so.

If next news is good (odds on that), those waiting on the sidelines hoping for a test of a floor (at 300p?) may all rush to get in, reigniting momentum. Then, beyond 400p, thoughts of 350/250 inclusion will begin to beckon.

[dominiccummings] 10/5/2024 10:32

I don't have access to trade details but I suspect we are now in a pattern where each morning we get a big deal that they have to pay a premium for followed by a number of small sellers taking the share price down.

[harry s truman] 10/5/2024 10:04

Surely we all know the answer to that one? Big news.

Nobody needs the full history of OXB to know that they were battered by the coronavirus pandemic restrictions on trials, because most of their customers were either working from home (i.e. not working) or had their trials put on hold because the hospital beds which need to be on standby for trials were reserved for covid.

Happily that is consigned to history now and will hopefully never be repeated.

We know from what Stuart has previously told us that OXB's costs for everything are somewhere around £130m per year.

Sales of around that and we roughly breakeven. Anything above that and our EBITDA margin rises ever upwards until we hit full capacity. So better than 20% on 2026 revenue and maybe eventually 30+%.

A couple of minor problems for small shareholders here are that OXB have told us for over a year now that they aren't routinely going to announce normal sized contract wins anymore - unless the customer specifically wants to.

(and)

They will instead keep us up to date with regular updates on this KPI table, but without actually telling us where and when we will get to see it.

So not for the first time we are in a position where all seems good (very good in fact), but we have to trust that it actually is going as OXB have told us (which it should be).

Out of the ordinary (i.e. big) news would help a lot, not just because it changes all previous guidance, but because the last paragraph of any RNS like that is usually a mini trading update on everything else.

Are we due something like that with the directors not buying? Probably. Will it happen sooner rather than later? Probably. Are biotech deal timeframes very long? For a big deal definitely.

I can only repeat my experience of the original Novartis tie-up. That was excitement on prospects, then impatience and repeat, with the price up and down accordingly. Eventually that got us to about £10 pre-covid (remember that much smaller company is no France, no Boston and only a handful of contracts) then covid changes everything (knocked us right down to £3(ish), built us up to £16(ish), knocked us right back down to £3(ish) again) meanwhile 6,000+ people with no previous hope got the Novartis treatment thanks to OXB.

You will have worked out long ago that I think the key to market success for OXB investors is getting back into the FTSE250. That seems to guarantee more of everything - more news coverage in the papers, more broker interest, more institutions who can buy (some in the trackers have to) and so on - and I'm convinced that eventually OXB will get there.

When? I don't know. My target is this year, but it might need the interim results showing that all is well and on track first. Meanwhile a lot of small investors are likely to have got fed up and sold (again).

Next index review is the end of this month but to double the price in 3 weeks would take some epic news. Could a really big deal (big enough for OXB to be in a closed period and big enough for them to have to announce because of changed guidance) do that in such a short time when OXB are in this sandwich year here between loss and profit?

I'm sure it's possible. Will it happen in the next 3 weeks? No idea.

Besides the potential detriment to drug access as a result of an immediate severance from Chinese CDMOs, industry respondents estimated that it would take up to eight years to switch manufacturing partners, according to a copy of BIO’s report obtained by Fierce Pharma.

Just for interest:-



Key takeaway 5 -

While the legislation is only under consideration at this point, given the strong bipartisan support for the bill and concerns from the national security community, it is expected that some form of the bill will become law in 2024.

OXB webcast Final question:-

Miles Dixon Question - Thank you and then secondly, if I could ask, I think it was Sébastien that mentioned about biotech still being difficult. I was just wondering if it was too early to see yet or if you are in fact seeing any new emerging pen profile of potential clients given the challenges at WuXi? Thank you.

Dr. Sébastien Ribault Answer - I have not personally been exposed to anyone coming to us and saying we absolutely want to leave competition and we want to work with you because of US political reasons, to put it that way. Are there people concerned about the situation? The answer is yes. Are they looking for backup plans? The answer is yes. Since we're talking about a text that has not been voted yet, we're still talking about people looking for backup plans, but there's nothing that I would consider as an active discussion as of now.

[harry s truman] 09/5/2024 15:17

In a word, would that be stochastic? Cue the call my bluff theme tune ;)

To stay in the same groove on my stuck record here, I think this month will either be ok or brilliant. Yes, I realise that's a rain or go dark prediction, but the likelihood here is that we will either continue to bobble along with 2 forward & 1 back on what they have told us, or...

Something very significant for OXB will drop and at that point our guidance changes and so does the share price.

Might be malaria. As Plutonian pointed out a long time ago, J&J have had very public supply problems in meeting their commercial needs. BMS have also experienced similar woes. Literally too many possibilities to guess from, but OXB are now in a very happy position of being there for anyone (with money and a need of our services).

[rathean] 09/5/2024 14:58

It's important to see a distribution/ accumulation phase before the next leg up. There's no predicting SPs, probabilities suggest further pipe laying before the next move all imo dyor ofc.

[dr darkstar] 09/5/2024 14:44

My experience of broker targets is that they're rarely worth the paper they're written on. What I do know is that the third attempt at 350 and a close above that will move us significantly higher again

[harry s truman] 09/5/2024 13:53

A good news story there Marcus. There must be a huge amount of satisfaction for the people working in labs everywhere when something like this turns out to be a success.

It's a bit like the story with Emily (first child with the CAR-T linked to us of course) where she awakened out of the post-treatment storm reaction to the sound of the hospital staff all gathered around her bed and singing happy birthday to her.

You'd need a heart of stone not to have something in your eye after that one.
