The next focusIR Investor Webinar takes places on 14th May with guest speakers from Blue Whale Growth Fund, Taseko Mines, Kavango Resources and CQS Natural Resources fund. Please register here.
If the aim is to get as much coverage as possible, a good starting point would be for Scancell themselves to retweet.
Burble,
Yes, unless things have changed Cytokeratin 8 is one of the targets for Modi2..

Thanks for that. Excellent interview - probably the best yet. Not easy in such a short space of time to explain the complexities and potential of the whole portfolio and I thought she pitched it at just the right level. Also for those who were concerned, Scancell clearly have no intention of delisting.

Yes well liked and well respected
Good to see that Brad Loncar will be interviewing Lindy Durrant on his UK tour 'profiling the best of life sciences in London, Oxford, and Cambridge.'

You'd have thought so but others here may know for certain.
Difficult decision whether to hold or sell. The obvious difficulty will be if you need access to the cash and can't sell but the upside is that C4X have great potential and strong leadership and I feel they may be biding their time waiting for conditions to improve for a NASDAQ IPO. If so that problem disappears.
Nice find thanks for sharing
Really? How can this sentence be read in any other way?
'If there was a 90% chance of exceeding an 85% ORR then you can be certain that 85% would have been the target ORR, not 70%.'
Perhaps 'without saying as much' part could be the problem?

The whole trial was designed and powered to produce a 70% response rate as that is the level which demonstrates that SCIB1 is having an impact (ie. 20% higher than CPIs alone) and merits further development. How/why could/would they change that to 85%?
Johnny,
Yes I know and it was your post (thanks) that prompted me to email as this seemed to contradict the original RNS which I understood to read 70% - see my post of 23rd. I think the wording of that part of the AGM presentation was unintentionally slightly ambiguous and could easily be interpreted as the probability of replicating the 85% response rate whereas they actually meant the probability of successfully passing the 70% threshold as the first cohort had done.
Anyway at least we know now. It will be really good news if they hit that 70% response rate which will mean the trial has been successful and a bonus if the response rate is higher.
Johnny,
Just an update on the 90% probability of success discussion regarding SCIB1.
Lindy has clarified that it is the probability of achieving a 70% response rate, not replicating the current 85%. To be precise it's the probability of achieving a '70% ORR on 43 patients' from the current SCIB1 study.

The NHS won't be paying for Modernal's vaccine - Moderna will be paying the NHS to run their clinical trials.
Ray,
SCIBI has produced some fablulous results in the adjuvant setting albeit in small numbers in a single arm trial but as a monotherapy. The issue I have with comparing the 49% from the Moderna vax's with SCIB1 lies with that 49% fiigure. If it represented the RFS rate of the Moderna arm of the trial then I can see how you might start to make a comparison, but it doesn't. It's the improvement in the likelihood of a recurrence compared to the results produced by Keytruda alone. So in that trial the Moderna patients were 49% less likely to have recurrence compared to the patients on the same trial receiving Keytruda alone. We have absolutely no clinical results from SCIB1 to compare that with.
Moderna still have to a long way to go with this vaccine. There's the Phase 3 clinical trial itself, a double blind randomised study in just under 1100 patients and then there's the whole process of seeking approval with the various regulators. It will be fantastic for Scancell if they're successful and should Scancell ever want to revisit the adjuvant setting with SCIB1 it might even provide an easier path through to approval. Just matching the results of a personalised vaccine with an off the shelf solution should be enough.
Ee
I apologise if I should have understood that from your post but it wasn't obvious to me because SCIB1 has never been trialled in this setting - ie. in combination with PD-1 CPI in the adjuvant setting. So how can you compare at this stage?
Keytruda is approved as an adjuvant therapy in melanoma and the Moderna trial was a randomised study with Ketruda alone as the control arm versus Keytruda plus the Moderna Vax. So the 49% figure is the reduction in the risk of recurrence/death when taking the combination versus treatment with Keytruda alone.
That is the whole point of my last sentence - if the phase III study is successful it validates the combination setting for cancer vaccines.
Ee
Seriously? Think if I was about to face surgery to have melanoma removed but was told I was in the very high risk category of it returning and someone offered me a vax which halved the chances of recurrence I'd jump at it. Credit where credit is due.
Success of any cancer vaccine is great news for Scancell but as 2cvguy mentioned earlier, this is particularly important as it establishes the utility of cancer vaccines in combination with checkpoint inhibitors.
Violindog,
Sorry, missed your post. Don't worry, the Moderna clinical trial won't have any impact on recruitment to the SCIB1 trial because it's in a different setting and recruiting from a different patient population. Moderna's trial is in the adjuvant setting - patients who have had their tumours surgically removed and are vaccinated to prevent recurrence whereas Scancell's trial is recruiting patients with advanced inoperable melanoma with tumour in situ.
Chelsea
Absolutely spot on.
Thanks for that Burble. I think she's also an investigator for the Moderna mRNA vax.
Really good to see that Heather Shaw, one of the SCIB1 study investigators will be presenting a poster at ASCO in Chicago in June. The abstract title:-
A DNA plasmid melanoma cancer vaccine, SCIB1, combined with nivolumab + ipilimumab in patients with advanced unresectable melanoma: Efficacy and safety results from the open-label phase 2 SCOPE trial.
Presenter: Heather May Shaw, MD, FRCP, MRCP | Mount Vernon Cancer Center
Abstract: 9535
| Poster Bd #: 319
ASCO isn't just another scientific conference, it's the largest oncology conference in the world and it would have been disappointing if Scancell were not represented.

Ruck,
Have just read the rest of your last post. This is what Scancell actually said about the 90% figure:-
'The aim is to achieve at least 18 further responses (i.e., 27 responses in total) which would statistically demonstrate that SCIB1, in combination with doublet therapy, exceeds currently achievable ORRs. Recruitment is on track with data available in H1 2024. Based upon the first 13 patients there is a greater than 90% probability that the second phase will also be successful.'
So they're not saying that there's a 90% probability that the 85% will be repeated in the full 43, they're saying that there's a 90% probability that the trial will be successful ie. reach the 70% response rate threshold.
