nice little nod to the possibility of commercialisation in the next 2 - 3 years for PTX. They’ve been pretty gentle in capital but I suppose it will cost a bit to run the phase 2 trial of PTX-100 in T cell lymphoma… but probably a lot less than a phase 3 trial

 encouraging results… the glamour has been all about prescient’s CAR-T platform but PTX-100 is looking like it might be in patients in the shorter term…





Continued promising results in PTX-100 T Cell Lymphoma Phase 1b Cohort

Key Points:

 Positive response rates, with two new complete responses in patients with relapsed and refractory PTCL since last update

 7 of 10 evaluable patients had durations of response exceeding standard of care

 Excellent safety profile maintained

 Will modestly increase number of patients to create robust regulatory package

for FDA meeting, following recent Orphan Drug Designation from FDA

MELBOURNE Australia, 16 March 2023: Prescient Therapeutics Limited (ASX: PTX), a clinical stage oncology company developing personalised therapies to treat cancer, is pleased to provide an update on the PTX-100 Phase 1b expansion cohort in relapsed and refractory T cell lymphomas (TCL). PTX-100 continues to show encouraging clinical activity in this difficult-to-treat patient population, with several clinical responses that include two patients with relapsed and refractory peripheral TCL (PTCL) that have had complete responses (complete eradication of cancer) since the prior update in November 2022, which is not generally expected in this disease. PTX-100 also continues to exhibit an excellent safety profile at the highest dose of 2000 mg/m2. The study is being led by globally renowned haematologist, Professor H. Miles Prince at Epworth Hospital in Melbourne, Australia.

Phase 1b Enrolment

A total of 13 TCL patients have been dosed with PTX-100: 8 patients with PTCL and 5 patients with cutaneous TCL (CTCL). Patients had received a median of 3 prior lines of therapy and up to 5 systemic prior lines of therapy. PTX-100 was administered at doses up to 2,000 mg/m2. The expansion cohort has met its minimum enrolment schedule, and the study is ongoing as patients are responding for longer than expected (see Clinical Activity, below).

Four patients currently remain on therapy and additional patients are being recruited.

              

 Safety

PTX-100 continues to exhibit an excellent safety profile on the study, with very few serious adverse events. Grade 3 (severe) adverse events observed as being possibly related to PTX-100 include cases of neutropenia, thrombocytopenia and anaemia. Several of these cases were observed in the same patient and the patients recovered/resolved these events. Prescient believes that such side effects are not uncommon in treating this patient population and are likely manageable.

Clinical activity

Although the primary goal of the study is to evaluate safety, PTX-100 continues to exhibit encouraging clinical activity in the difficult-to-treat patient population, especially when considered against responses expected from current standards of care. This is summarised in Table 1.

Comments of note for this update:

 All 13 TCL patients were assessable for safety; 10 patients were assessable for

efficacy. 5 patients had r/r PTCL and 5 patients had r/r CTCL.

 Targeted progression free survival (PFS) is median, however with small patient

numbers in this study PTX is reporting mean PFS. In this update, PFS is impacted by newer patients on the study, whose treatments are in the earlier stages but remain ongoing. This results in a lowering of the overall PFS figures. PFS for r/r PTCL was 9.2 months and for r/r CTCL was 8.2 months.

 In CTCL, an additional measure of clinical utility is Clinical Benefit Rate (CBR), which includes those patients with complete and partial responses and those with durable

Next steps

Based on encouraging data so far, regulatory advisors have recommended enrolling seven additional patients in order to support a more robust data package for a meeting with the US FDA.

Prescient is planning a subsequent Phase 2 trial in TCL, which will be conducted subject to satisfactory Phase 1b outcomes. Prescient will seek to apply for this Phase 2 trial to be an Accelerated Approval trial with the FDA in an Orphan Indication. If this is granted, Accelerated Approval could pave the way for the Phase 2 trial to be the study enabling

1 H.M. Prince; et al; J Clin Oncol; 2010

           

 expedited regulatory approval of PTX-100. If Accelerated Approval is not granted, the Phase 2 trial will proceed as per conventional drug development pathways, with a subsequent study likely required for approval.

Prescient will also be seeking clarification on the dose optimisation and dose schedule considerations for the Phase 2 study pursuant to the FDA’s Project Optimus, which seeks to maximizes not only the efficacy of a drug but also its the safety and tolerability.

Prescient will be applying for a meeting the FDA later this year. A favourable outcome would see the registrational Phase 2 study open within 12 months, subject to satisfactory results from the Phase 1b trial. A possible scenario may involve regulatory interactions taking place and/or a subsequent Phase 2 trial initiated before the current Phase 1b officially concludes, due to the long duration of responses being observed in this Phase 1b study.

To facilitate further studies, Prescient will conduct another manufacturing campaign of PTX- 100, planning for this has already commenced. Manufacturing will be conducted and documented at higher levels of rigour required to support later stage trials and regulatory submissions.

Prescient’s Chief Medical Officer, Dr Terrence Chew, said, “We are very pleased to see these promising efficacy and safety results in this difficult to treat patient population. With confirmation of these preliminary results, we expect to proceed expeditiously to a registration trial and to be able to provide PTX100 to these patients who desperately need more effective therapies.”

Prescient’s CEO and Managing Director, Steven Yatomi-Clarke, said, “It is very exciting to see this clinical data for PTX-100 continue to unfold so favourably, especially in these relapsed and refractory T cell lymphomas, which are particularly difficult to treat and where other therapies have failed. Unlike other TCL therapies, PTX-100 continues to exhibit an excellent safety profile, and the patient responses we are observing are very promising for a Phase 1b study.

Whilst Phase 1 trials necessarily focus on safety, we have a valuable opportunity to bolster our trial with a small number of additional patients to enable Prescient to have a more meaningful and productive dialogue with the FDA. This follows last week’s decision by the FDA to grant PTX-100 Orphan Drug Designation for all TCLs, and presents an exciting and unique opportunity for Prescient and for TCL patients awaiting more effective therapies.”

About Prescient Therapeutics Limited (Prescient)

Prescient Therapeutics is a clinical stage oncology company developing personalised medicine approaches to cancer, including targeted and cellular therapies.

Targeted Therapies

PTX-100 is a first in class compound with the ability to block an important cancer growth enzyme known as geranylgeranyl transferase-1 (GGT-1). It disrupts oncogenic Ras pathways by inhibiting the activation of Rho, Rac and Ral circuits in cancer cells, leading to apoptosis (death) of cancer cells. PTX- 100 is believed to be the only GGT-1 inhibitor in the world in clinical development. PTX-100 demonstrated safety and early clinical activity in a previous Phase 1 study and recent PK/PD basket study of hematological and solid malignancies. PTX-100 is now in a Phase 1b expansion cohort study in T cell lymphomas, where it is showing encouraging efficacy and safety. The US FDA has granted PTX-100 Orphan Drug Designation for all T cell lymphomas.

PTX-200 is a novel PH domain inhibitor that inhibits an important tumour survival pathway known as Akt, which plays a key role in the development of many cancers, including breast and ovarian cancer, as well as leukemia. Unlike other drug candidates that target Akt inhibition, PTX-200 has a novel mechanism of action that specifically inhibits Akt without non-specific kinase inhibition effects. This highly promising compound is currently in a Phase 1b/2 trial in relapsed and refractory AML, where it has resulted in 4 complete remissions so far. PTX-200 previously generated encouraging Phase 2a data in HER2-negative breast cancer and Phase 1b in recurrent or persistent platinum resistant ovarian cancer.

Cell Therapies

OmniCAR: is a universal immune receptor platform enabling controllable T-cell activity and multi- antigen targeting with a single cell product. OmniCAR’s modular CAR system decouples antigen recognition from the T-cell signalling domain. It is the first universal immune receptor allowing post- translational covalent loading of binders to T-cells. OmniCAR is based on technology licensed from Penn; the SpyTag/SpyCatcher binding system licensed from Oxford University; and other assets.

The targeting ligand can be administered separately to CAR-T cells, creating on-demand T-cell activity post infusion and enables the CAR-T to be directed to an array of different tumour antigens. OmniCAR provides a method for single-vector, single cell product targeting of multiple antigens simultaneous or sequentially, whilst allowing continual re-arming to generate, regulate and diversify a sustained T-cell response over time.

Prescient is developing OmniCAR programs for next-generation CAR-T therapies for Acute Myeloid Leukemia (AML); Her2+ solid tumours, including breast, ovarian and gastric cancers; and glioblastoma multiforme (GBM).

CellPryme-M: Prescient's novel, ready-for-the-clinic, CellPryme-M technology enhances adoptive cell therapy performance by shifting T and NK cells towards a central memory phenotype, improving persistence, and increasing the ability to find and penetrate tumours. CellPryme-M is a 24-hour, non- disruptive process during cell manufacturing. Cell therapies that could benefit from additional

 productivity in manufacturing or increased potency and durability in-vivo, would be good candidates for CellPryme-M.

CellPryme-A: CellPryme-A is an adjuvant therapy designed to be administered to patients alongside cellular immunotherapy to help them overcome a suppressive tumour microenvironment. CellPryme-A significantly decreases suppressive regulatory T cells; increases expansion of CAR-T cells in vivo; increases tumour penetration of CAR-T cells. CellPryme-A improves tumour killing and host survival of CAR-T cell therapies, and these benefits are even greater when used in conjunction with CellPryme-M pre-treated CAR-T cells.

The Board of Prescient Therapeutics Limited has approved the release of this announcement.

#FDA orphan drug designation
stale
Added one year ago

This straw is mostly to help me keep track of what's happening.

Today's announcement is a follow up to the one in July last year.

Essentially, the latest announcement is that the FDA has broadened the scope of Prescient's orphan drug designation for their drug PTX-100 from just peripheral T-cell lymphomas to all T-cell lymphomas.

The drug is not actually finished trials yet though. They say they expect to share updates on the trial shortly.

#4C quarterly
stale
Added one year ago

Nothing really new added in this 4C.

  • Continued work on clinical trials and new OmniCAR system.
  • Net cash outflow $323,000. Although this would have been $1.96M outflow if not for a government grant.
  • Cash balance of $21M after raising about $10.5M during the quarter.
  • This gives them a couple of years of funding without any new grants.


But the main thing I was looking for was anything about their CellPryme-M and CellPryme-A technologies. They've strongly hinted that they can licence this for money to other companies working on CAR-T therapies:

``Prescient believes the CellPryme platforms can open the door to potential licensing and commercial collaborations.''

But the current status is only:

``...management continues to raise awareness of these programs among the global medical community, the biotechnology industry and investors.''

Which sounds to me like any actual cash transactions for the technology will be at least a couple of years away. On the issue of timing they say:

``Such arrangements are always challenging to achieve and take time, but interactions so far have been encouraging.''

So I don't yet know what to think of how CellPryme should figure in the thesis, if at all. Thoughts welcome!

PTX-100 Expansion Cohort Continues to Exhibit Safety & Encouraging Clinical Activity

Key Points:

 Ongoing safety profile very favourable

 PTX-100 continues to exhibit encouraging clinical activity

 Additional CTCL patients to be added to trial

MELBOURNE Australia 25 October 2022: Prescient Therapeutics Limited (ASX: PTX), a clinical stage oncology company developing personalised therapies to treat cancer, is pleased to provide an update on the PTX-100 Phase 1b expansion cohort in relapsed and refractory T cell lymphomas (TCL). The study is being led by globally renowned haematologist, Professor H. Miles Prince at Epworth Hospital in Melbourne, Australia. PTX- 100 continues to exhibit an excellent safety profile at the highest dose of 2000 mg/m2. Moreover, PTX-100 continues to show encouraging clinical activity in a difficult to treat patient population, including a striking response in a patient with refractory cutaneous TCL (CTCL).

Phase 1b Enrolment

The expansion cohort has targeted 8-12 patients. A total of 8 patients have been screened and 7 patients have been dosed with PTX-100 in the expansion cohort so far: 4 with peripheral TCL (PTCL) and 3 with CTCL. Patients had received a median of 4 prior lines of therapy and up to 6 prior lines of therapy. PTX-100 was administered at 2,000 mg/m2. Four patients remain on therapy and additional patients are being recruited.

Safety

PTX-100 continues to exhibit an excellent safety profile on the study. There have been very few adverse events in the expansion cohort so far, and no serious adverse events related to PTX-100.

2 PTCL patients that had commenced therapy withdrew from the study for reasons unrelated to the trial. Another PTCL patient passed away due to reasons not associated with the study, as frequently occurs in studies of advanced malignancies. In each of these cases, subjects were not on the study long enough to observe responses, however, relevant pharmacokinetic and safety data were still collected, which are to the primary objectives of the study.

             

 Clinical activity

Although the primary goal of the expansion cohort is to evaluate safety, PTX-100 continues to exhibit encouraging clinical activity in the difficult-to-treat patient population. An update of observed responses is summarised below:

 Patient 121-003 (previously reported in dose escalation component of the study) with aggressive PTCL that had failed five prior treatments, had a partial response that endured for over 32 months before the disease progressed.

 Patient 121-010 with CTCL that had failed 4 prior lines of therapy experienced a very good partial response (VGPR), which is almost a complete response, that has endured for 6 months so far. This patient remains on therapy. Please refer to the case study photos below.

 Another 2 patients with CTCL that failed three prior therapies have experienced stable disease that have endured for 3-4 months so far and remain on therapy.

Case study: Patient 121-010

CTCL patient that had failed 4 prior therapies. Patient had VGPR on PTX-100 and is still on treatment.

           

             

 Next steps

In light of these encouraging responses in CTCL in particular, Prescient has amended the study protocol to accommodate the recruitment of additional CTCL patients. Recruitment remains on schedule, notwithstanding the new objective of recruiting additional CTCL patients, which may commensurately extend the study period. The study will remain open while patients continue to derive clinical benefit from PTX-100. Prescient looks forward to providing further details on the expansion cohort study in the coming quarter.

Principle Investigator of the study, Professor H. Miles Prince, said, “We continue to see impressive responses in both systemic and cutaneous T cell lymphomas on this study. Furthermore, PTX-100 continues to be extremely well tolerated by patients. We look forward to continue accruing patients to the trial who otherwise have limited treatment options.”

Prescient’s CEO and Managing Director, Steven Yatomi-Clarke said, “It is very exciting to see PTX-100 show clinical activity in a patient population that is notoriously difficult to treat, and where these patients have failed several lines of prior therapies. Furthermore, PTX-100 continues to exhibit an excellent safety profile, which is uncharacteristic of available TCL therapies. It is exciting to see encouraging responses in CTCL patients, alongside PTCL patients, and we will aim to recruit more CTCL patients to the study. We look forward to sharing these updates with the market.”

I always enjoy listening to Steve Yatomi-Clarke discuss PTX's progress and plans when I tune in. However, as a long term shareholder (IRL) I'm developing a touch of scepticism based on the regularity of presentations and IR exercises...


Steve presents weekly sometimes more than once in a week and whilst I understand they're a pre-revenue biotech and therefore communication and IR relations are pretty important. BUT... Does anyone worry that this is just a way to string the market along and continue to milk the market for cap raises? I don't feel this way with PTX, I feel they've been decent stewards of shareholder capital but I have some doubts just based on the extreme number of presentations...


Does anyone else have a view on this for PTX or more generally?

#4C
stale
Added 2 years ago

As I mentioned in the straw about the CellPryme-M platform, I'm looking to see if this new program is causing an increase in costs like @GazD suggested.

Their most recent 4C actually had a pretty big decrease in operating cash flow: -$1,167,000 (June) vs -$1,633,000 (March), which is largely driven by a reduction in R&D costs: $493,000 (June) vs $1,072,000 (March). Their prior 4C (December 2021) had R&D in the middle $827,000, and September 2021 was roughly the same.

In the most recent 4C, on the topic of CellPryme-M they say that ``This program has been in development for some time in stealth mode whilst data was generated and patents filed.'' and so maybe the higher R&D spends in the previous quarters accounted for that.

The takeaway: so far it looks like the CellPryme-M platform isn't leading to increased costs. Of course, a significant reduction in R&D spending by a biotech is an interesting fact by itself, since that's basically their entire business. So I'll be watching to see what happens there.

#CellPryme platform
stale
Last edited 2 years ago

[Edited to add disclaimer]

I dug into some of the details of the announcement in @GazD's straw. So the company is saying that one of the main problems with Car-T therapies is that the production process produces too many of the wrong kind of T-cell. But they've developed a pre-treating process that takes only 24 hours, after which you then take the cells and stick them into your standard production process for whatever treatment you're producing. This then results in more of the right kinds of cell after the full production is completed. In particular, the cells will last longer and be better able to locate the tumors that they're trying to attack.

They're saying that they can use these to improve their own products, but I suspect that probably the most important thing about the announcement is that they're aiming to make this available to other companies to licence for their own drug development. They claim it's ready now, so if this turns out to be true, and they can get other companies interested, then I think the company could really be in good shape, and importantly, can start getting earning some cash before they run out --- their March 4C estimated 2 years of remaining cash. The other important implication of the announcement, as @GazD suggests, is this new program might increase expenses and force them to pass the hat around much sooner.

So, what I'm watching: can they get any traction on this CellPryme-M platform by the end of CY2022? How much are expenses increasing in their next 2 quarterly updates?

Not much to report, but I finally got around to following up wtih Rebecca Lim (Prescient's Director of Scientific Affairs) about their IP and the announcement about the expansion of their PTX-100 trial. In retrospect, I should have been more specific with my questions, so I didn't get a particularly informative response. At any rate, here's the questions that I asked:

  • From what I understand from the [journal article that Rebecca sent me previously], the Omnicar system is a development of the Spytag/spycatcher system. Is this correct?
  • If so, can you give an outline of what's unique about Omnicar? Does Prescient own all the IP for this system?
  • I saw the ASX announcement on 27th July about the successful phase 1b trial of PTX-100, and the results sound really encouraging. Was this result published somewhere, and if so, can you please point me to the reference?"

Here's Rebecca's response:
"To answer your questions: we’ve licensed the IP for the OmniCAR system which comprises of the SC/ST system from Oxford University and the SC/ST application for cell therapies which is from U Penn. OmniCAR is unique amongst universal immune receptor systems due to its covalent binding system and rapid binding. This addresses challenges in the field as unbound binders can negatively impact targeting of the tumour cells and/or safety concerns associated with unbound binders in circulation.

The PTX-100 trial outcomes are yet unpublished as we are moving onto an expansion trial now. You might have seen on the same ASX announcement, we have seen some encouraging results with relapsed/refractory PTCL patients and will be expanding into a cohort focusing on this patient group."

So it's still not clear to me exactly what differentiates the Omnicar system from other Spytag/Spycatcher systems, but her brief mention about covalent binding matches what is described in this paper [Minutolo et al. (2020), J.Am.Chem.Soc. 142], so I'm assuming that this is the same thing. None of the authors on that paper are listed on Prescient's website, although in their latest investor presentation (ASX announcement 4/8/21) the two authors who declared patents in the paper are both mentioned, so presumably they have some relationship with the company.

[Updated with my new understanding of how Omnicar fits in.] This company is hard to know much about yet. They are primarily focussed on cancer treatments and it looks like they have two have two different (possibly related) therapeutic approaches, one is based around the CAR-T (Chimeric antigen receptor T cells) technology and another one that they call "Targeted therapies". The basis of the whole thesis is their Omnicar system (a type of CAR-T system), which is still very much at the pre-clinical stage. They have developed the technology into their own system and labelled it "Omnicar". I had quite a bit of trouble finding much of the scientific research output that this company is based on. I contacted their investor relations team to ask for some references but they didn't write back. I was then suspicious, so I got in touch with Rebecca Lim, who is listed on the website as Director of Scientific Affairs. She has a position at Monash University, so I contacted her on that email address. She sent me a paper [Minutolo et al. (2020), J.Am.Chem.Soc. 142] from the Journal of the American Chemical Society. This paper is clearly where the CEO (Steven Yatomi-Clarke) gets the diagrams for his presentations. The paper is quite interesting and there seems to be a compelling scientific case, so I've now bought a small parcel of shares. (However, I'm a mathematician, not a biologist, so while I can read charts of experimental data, evaluating cancer therapies is definitely not my speciality). After digging around a bit more, I've come up with some more info. From their ASX announcement on 26/5/21 they've licensed the Spytag/Spycatcher system from Oxford University and a covalent binding system from the University of Pennsylvania, which is what is described in the Minutolo et al. paper. It looks like this is what is now called "Omnicar". From the paper it seems that the UPenn system was specifically built on the Spytag/Spycatcher system and so presumably they needed to licence both to use the UPenn patents. They've identified three potential therapeutic directions for Omnicar research (see their ASX announcement on 18th Jan 2021): -Acute Myeloid Leukemia; -solid tumours including breast, ovarian and gastric cancers; and -glioblastoma multiforme. I don't know enough about these to comment on the likelihood of success. The other area they are working on is the "Targeted therapies", which consists of two drugs PTX-100 and PTX-200, which are both in clinical trial stages. If either of these work out this would help pay the bills while they get the Omnicar system through the research and clinical trial process. They have also mentioned in the past that they are looking into anti-viral activity against SARS-CoV-2, although in their March 2021 quarterly update they say that because there's so many vaccines out now they are putting this research on hold. It's hard to value the company, since they still haven't got anything concrete to treat any specific cancer, so I can only guess. (My fair value estimate is the price I hope to pick up more shares for, based on the recent share price movements, not business fundamentals.) They do have a lot of cash on hand --- in the 2020/2021 annual report they declare $16 million in cash & equivs, with a net loss of $4.1 million over the year, giving them about 3 years at current rates before needing more cash. Given the early stage of Omnicar research, I imagine it will be at least this long before any treatments are clinically available, but assuming the current clinical trials work out (a big assumption) the PTX-100 and PTX-200 drugs may provide some wins earlier than that.
