Comments by CEO Ulf Hannelius
This past financial year we have significantly advanced the therapeutic diabetes vaccine Diamyd. With a focus on our Diamyd platform precision medicine supported by clinical results from several international placebo controlled randomized trials, we are 1) Moving ahead with a pivotal phase 3 trial in individuals newly diagnosed with type 1 diabetes (T1D) carrying the genetic HLA DR3-DQ2 haplotype, 2) Advancing our efforts to treat individuals at-risk for T1D through an innovation milieu financially supported by the Swedish government, 3) Evaluating Diamyd in individuals diagnosed with Latent Autoimmune Diabetes in Adults (LADA) and 4) Progressing at high speed the build-up of our own manufacturing facility in Umeå. These activities are supported by a strong financial position that give us a runway into 2023.

During the past quarter we announced new sensitivity analyses that support the robustness of our clinical results with Diamyd that show a significant and clinically relevant effect on preserving endogenous insulin production and lowering blood glucose in individuals that carry the HLA DR3-DQ2 haplotype. In addition, we announced new positive results from the phase 2b trial DIAGNODE-2 that show that individuals positive for the HLA DR3-DQ2 haplotype and treated with Diamyd measure significantly shorter time with elevated blood glucose and significantly more time with normal blood glucose (TIR, Time In Range). These findings are very comforting and strongly support the design of the precision medicine phase 3 trial DIAGNODE-3. Work is ongoing to start the trial in Europe and the US. We recently received the greenlight from the Swedish MPA and we are expecting to hear from the authorities in the other European countries within the coming months. The trial protocol has also been submitted to the US FDA and here we still have some outstanding questions from the FDA that need clarification before the trial can start in the US. We will make sure to work closely with the FDA and other authorities to advance Diamyd as fast as possible. On the prevention side we recently achieved a major milestone as we together with a stellar team of collaborators received in total MSEK 40 from the governmental innovation office VINNOVA for the five-year innovation milieu ASSET (AI for Sustainable Prevention of Autoimmunity in the Society). The focus of ASSET is to predict the individual’s risk of being diagnosed with T1D and to evaluate therapeutic efforts to delay or prevent progression to diagnosed T1D. This is a very exciting and ambitious long-term project that I believe will produce results that are significant for both Diamyd Medical, our partners, and the broader field of T1D and autoimmune diseases.

We are also looking forward to the first results from the GADinLADA trial where intralymphatic injections of Diamyd are evaluated in individuals diagnosed with LADA. This is an important and large indication that is genetically similar to T1D but is still often diagnosed and treated like type 2 diabetes (T2D). With the very promising results from T1D we see great promise in broadening the use of Diamyd also for LADA, an indication that represents up to 10% of all individuals diagnosed with T2D. In parallel with these clinical efforts, the work to set up our own manufacturing facility in Umeå Sweden is progressing according to plan. The small-scale experimental manufacturing is in place, and we soon expect to have the large-scale equipment installed. The main aim is to get the manufacturing process GMP certified, and the facility approved to have new material in place for a potential application for accelerated market approval and commercialization. Also, to further secure our long-term control of the manufacturing strategy we recently acquired the property where we have our manufacturing facility. This will provide us opportunities going forward to scale-up and broaden our activities in Umeå in alignment with market demand and sustainability goals.

Finally, in addition to the recent non-dilutive grant from VINNOVA that will support the prevention efforts with Diamyd, we have also strengthened our cash position. During the financial year we received MSEK 148 from the divestment of Companion Medical and MSEK 60 from a directed share issue. We recently conducted an additional direct issue, of SEK 150, which in all make sure we can continue to advance at full pace and reach several important milestones.

I would like to thank all our shareholders, partners, collaborators and employees for your support and valuable work.

Significant events during the fourth quarter
June 1, 2021 – August 31, 2021
GAD65 manufacturing facility on track for Diamyd vaccine production
Small-scale experimental production of the recombinant human protein GAD65, the active component in the therapeutic diabetes vaccine Diamyd, was established at the manufacturing facility in Umeå. Large-scale production is being set up primarily using Cytiva equipment. The future CGMP certified production process at the facility is a key part of Diamyd Medical’s regulatory strategy for potential future conditional and accelerated market approvals.

Additional analyses showed robust treatment effect of the therapeutic vaccine Diamyd
Diamyd Medical conducted, as part of interactions with regulatory agencies, two new analyses on the large meta-analysis dataset of 627 individuals that participated in four previous placebo controlled clinical trials evaluating the efficacy and safety of the therapeutic diabetes vaccine Diamyd. Both analyses supported the clinical relevance and significance of the treatment benefits of Diamyd, which further support the design of the Phase III trial DIAGNODE-3 which is planned to start recruiting patients later this year.

Diamyd Medical secured precision medicine patent for prevention and treatment of autoimmune diabetes
The European Patent Office has informed Diamyd Medical that the Company’s patent application regarding prevention and treatment of autoimmune diabetes in individuals carrying the HLA DR3-DQ2 gene will be granted. The patent is valid until 2035 and provides central protection in Europe for the treatment or prevention of genetically defined autoimmune diabetes using GAD, which is the active component in the therapeutic diabetes vaccine Diamyd. The patent claims cover the patient population in which Diamyd has shown efficacy and is targeted in the upcoming Phase III trial DIAGNODE-3.

24-month follow-up of Phase IIb Diamyd clinical trial indicated continued positive treatment effect post 15 months
50 out of the 109 individuals in DIAGNODE-2 who were included in an extension study had been followed for a total of 24 months. The actively treated individuals carrying HLA DR3-DQ2, in total 15 individuals, followed their expected trajectory from 15 to 24 month, showing no indication of diminishing treatment effect compared to their progression up to 15 months. As also expected, safety at 24 months looked good with no difference in adverse events between actively treated and placebo treated individuals.

Diamyd Medical was elected to present Diamyd meta-analysis results at the EASD diabetes conference
A scientific abstract detailing the latest findings from a meta-analysis based on data from more than 600 individuals with type 1 diabetes participated in clinical trials with the diabetes vaccine Diamyd (GAD-alum) has been elected to be presented orally on October 1 at the 57th EASD Annual Meeting (European Association for the Study of Diabetes).

Significant events after the reporting period

Diamyd Medical and partners were awarded SEK 40 million from VINNOVA for the prevention of autoimmune diseases
The Swedish governmental innovation agency VINNOVA provides SEK 40 million in financing for an innovation milieu in sustainable precision health that will be led by Diamyd Medical. The project aims to develop and evaluate new algorithms based on artificial intelligence (AI) for preventive precision medical treatments for type 1 diabetes and other autoimmune diseases. The innovation milieu also includes Mainly AI AB, Lund University, Sahlgrenska University Hospital, the National Diabetes Register and the Leading Healthcare Foundation. Diamyd Medical’s part of the five- year grant amounts to approximately SEK 18 million.

Analysis that supports the effect of the diabetes vaccine Diamyd will be presented at a the ISPAD conference
A new analysis showing the effect of the diabetes vaccine Diamyd (GAD-alum) in reducing the time a patient has high blood glucose, was selected to be presented at the ISPAD conference (The International Society of Pediatric and Adolescent Diabetes), which this year will be held on 13-15 October. The analysis is based on data from Continuous Glucose Monitoring (CGM) and will be presented by Professor Johnny Ludvigsson, Principal Investigator of the clinical trial DIAGNODE-2.

First regulatory approval received to start the Phase III trial DIAGNODE-3 with the diabetes vaccine Diamyd
The Swedish Medical Products Agency gave approval for the start of DIAGNODE-3, a placebo-controlled precision medicine Phase III trial with the diabetes vaccine Diamyd. The trial is designed to confirm the efficacy and safety of Diamyd in individuals recently diagnosed with type 1 diabetes, who carry the genetically defined haplotype HLA DR3-DQ2.

FDA paused the start of DIAGNODE-3 in the US
The start of the Phase III trial DIAGNODE-3 in the United States was paused by the US Food and Drug Administration (FDA) to clarify certain outstanding questions regarding the study drug. Diamyd Medical will be notified of which questions that are outstanding within 30 days.

Acquisition of property with manufacturing facility in Umeå
Diamyd Medical announced the acquisition of the property in Umeå, Sweden, where production of the recombinant protein GAD65, the active component in the therapeutic diabetes vaccine Diamyd is being established. The property is acquired for a purchase price of SEK 24.5 million and comprises approximately 20 000 square feet including the 10 000 square feet Diamyd Medical rents today, as well as 90 000 square feet of land area.

Proceeds of SEK 150 million were raised via a directed share issue
A directed share issue of 5 357 143 B-shares at a price of SEK 28 per share was completed. The price corresponded to a discount of approximately 17.0 percent calculated on the volume weighted average price on the Nasdaq First North Growth Market for the preceding 30 trading days. Through the directed share issue, the Company received gross proceeds of SEK 150 million. The directed share issue was subscribed by qualified investors.

Two drugs in clinical development
Diamyd and Remygen are drugs in clinical development that focus on the underlying disease mechanisms of diabetes; the dysfunction and loss of insulin-producing beta cells in the pancreas.

Diamyd is an antigen-specific immunomodulating precision medicine diabetes vaccine for the treatment and prevention of autoimmune diabetes (type 1 diabetes and LADA, Latent Autoimmune Diabetes in Adults).

Clinical data indicate the potential of the diabetes vaccine Diamyd to halt or stop the autoimmune destruction of insulin-producing beta cells in individuals that carry the HLA DR3-DQ2 haplotype. The effect is achieved by antigen-specific reprogramming of immune cells by administration of low doses of Diamyd in superficial lymph nodes. By maintaining the endogenous insulin production, Diamyd has the potential to make a significant difference in the daily life of patients as well significantly reduce the complications of type 1 diabetes. Topline results from the Phase IIb trial DIAGNODE-2 demonstrated a significant treatment effect of Diamyd in the predefined genetic patient group.

Remygen is an oral regenerative and immunomodulatory drug candidate for the treatment of autoimmune- and type 2 diabetes. By stimulating the growth of insulin-producing cells, Remygen has the potential to reverse the disease progression in autoimmune- and type 2 diabetes. Based on clinical data, Remygen has also the potential to protect against hypoglycemia by improving the hormonal response. Remygen is now being investigated in a clinical Phase I/II trial (ReGenerate-1), where clinical efficacy is evaluated with the aim of optimizing the treatment regimen ahead of registration-based trials.

Clinical trials
Type 1 diabetes is a devastating disease which requires daily treatment with insulin to sustain life. The importance of finding a drug that improves the prospects for patients with diabetes is of utmost importance. The effect of intralymphatic administration of Diamyd, an antigen-specific precision medicine immunotherapy aimed at stopping the immune system’s attack on insulin-producing beta cells in autoimmune diabetes, will be evaluated in the Phase III trial DIAGNODE-3 and is evaluated in the Phase II trial GADinLADA.

Remygen, which aims to stimulate the growth of beta cells in patients with diabetes, is evaluated in patients in a Phase I/II trial.

Upcoming clinical trial
Trial with Diamyd in lymph node

DIAGNODE-3 – DIAMYD IN LYMPH NODES WITH ORAL SUPPLEMENTATION OF VITAMIN D
The placebo-controlled Phase III trial DIAGNODE-3 will include approximately 330 individuals aged 12 to 28 who have been recently diagnosed with type 1 diabetes and who carry the genetically defined haplotype HLA DR3-DQ2. The trial will be conducted at approximately 50 clinics in Europe and the United States, where almost half of all individuals with type 1 diabetes are estimated to carry the current haplotype. After an initial month in which all trial participants receive vitamin D, the individuals will be randomized 2:1, ie two out of three trial participants will receive three intralymphatic injections of Diamyd and one in three will receive the corresponding placebo at one month intervals, with one primary reading 24 months after trial start. The design provides, based on efficacy data from previous studies on the HLA-restricted patient population, a high probability of reaching the primary endpoints; preservation of stimulated C-peptide and lower HbA1c. The Coordinating Investigator for the trial is Professor Johnny Ludvigsson at Linköping University. The Sponsor of the trial is Diamyd Medical.

Ongoing clinical trials
Trial with Diamyd in lymph node

GADinLADA – DIAMYD IN LYMPH NODES WITH ORAL SUPPLEMENTATION OF VITAMIN D
The main aim of the trial is to evaluate the safety of intralymphatic treatment with Diamyd in patients with LADA (Latent Autoimmune Diabetes in Adults). The patients have been recruited in Norway at the Norwegian University of Science and Technology (NTNU) in Trondheim, in collaboration with St. Olavs Hospital, University Hospital in Trondheim, and in Sweden at the Center for Diabetes, Akademiskt specialistcentrum, an academic specialist unit run in collaboration between Stockholm County’s healthcare area, Karolinska Institutet and Karolinska University Hospital. The patients included in the trial are between 30 and 70 years old, have been diagnosed with LADA within the last 18 months and are not yet on insulin therapy. The Sponsor of the trial is the Norwegian University of Science and Technology with Ingrid K Hals as Sponsor’s representative. Diamyd Medical contributes with study drugs, expertise and some financial support for immunological analyzes and determination of HLA haplotypes. The first results from the trial are planned to be announced in early 2022.

Trial with Remygen (GABA)

REGENERATE-1 – REMYGEN /ALPRAZOLAM
An open-label, investigator initiated clinical trial with Remygen. The trial includes approximately 36 patients aged 18-50 who have had type 1 diabetes for more than five years with low to non-existing insulin production. Safety and initial efficacy results from the dose escalation section of the trial have paved the way to initiate the main trial and have also demonstrated a potential effect of Remygen to improve the hormonal response to hypoglycemia. The main trial evaluates whether the insulin-producing cells can be regenerated and if the hormonal response to hypoglycaemia can be improved using Remygen and the combination of Remygen and Alprazolam. The trial is led by Professor Per-Ola Carlsson at Uppsala University, Sponsor of the trial.

Manufacturing of GAD65 in Umeå
A new facility for vaccine manufacturing is being set up in Umeå, the Capital of Västerbotten County in Sweden, for the manufacture of recombinant GAD65, the active pharmaceutical ingredient in the therapeutic diabetes vaccine Diamyd currently in late-stage clinical development. The 10 000 square feet site, comprising of clean rooms, laboratory facilities and office space, will facilitate full control, predictability and scalability of the manufacturing technology of the active ingredient. Diamyd Medical has chosen Cytiva’s configurable single-use bioprocess manufacturing platform FlexFactory for the process. Small-scale experimental production of GAD65 is now established at the manufacturing facility. Large-scale production is being set up primarily using Cytiva equipment.

Title: GlycoConnect ADCs Based on Topoisomerase 1 Inhibitor Exatecan (SYNtecan E) Show Excellent In Vivo Efficacy and Tolerability
Time: 9:30pm CEST / 3:30pm EDT / 12:30 PDT
Authors: Floris van Delft, Remon van Geel, Jorin Hoogenboom, Marloes Wijdeven, Laureen de Bever, Sorraya Popal, Jord van Schaik, Sander van Berkel
Synaffix utilizes GlycoConnect, a proprietary technology based on the native glycan of monoclonal antibodies, which is used as a privileged conjugation site for ADCs. In addition, a highly polar spacer technology (HydraSpace) enables the conjugation of any cytotoxic, hydrophobic payload, providing ADCs with significantly expanded therapeutic index (TI).

Camptothecins form a class of clinically relevant chemotherapy drugs based on their ability to inhibit DNA topoisomerase 1 while also demonstrating excellent potential as payloads for antibody-drug conjugates (ADCs), as exemplified by the recent market approvals of Enhertu and Trodelvy.

Synaffix’s data demonstrate that:

Exatecan, a clinically validated and potent campothecin, is readily combined with Synaffix’s HydraSpace technology, resulting in the SYNtecan E linker-payload
GlycoConnect ADCs of trastuzumab were generated by conjugation of SYNtecan E to antibodies and evaluated for efficacy and tolerability
Complete tumor regression was observed in a mouse xenograft study (BT-474) after a single dose, while safety studies in mice corroborated high tolerability of SYNtecan E ADCs
Prof. Floris van Delft, CSO of Synaffix, said: "We are delighted to be presenting new data on our groundbreaking technologies at this distinguished annual meeting. As the ADC community once again comes together to share its latest research, Synaffix is excited to showcase its continued efforts to develop truly best-in-class ADC therapeutics."

In the last few months, Synaffix has signed significant ADC technology out-licensing agreements with Kyowa Kirin, a global specialty pharmaceutical company; ProfoundBio, an emerging oncology biotherapeutics company; and Innovent Biologics, a leading biopharmaceutical company developing innovative medicines for the treatment of major diseases. These come in addition to earlier collaborations with ADC Therapeutics, Mersana Therapeutics and Shanghai Miracogen. Three ADCs using Synaffix’s technology are in the clinic.

Prescient has some very positive findings to share about its OmniCAR platform’s tumour-killing abilities

On October 13, 2021 Prescient reported it’s OmniCAR platform could overcome the limitations of CAR-T treatments for cancer and it’s attracting the attention of leading global therapy decision makers (Press release, Prescient Therapeutics, OCT 13, 2021, View Source;utm_medium=rss&utm_campaign=prescient-has-some-very-positive-findings-to-share-about-its-omnicar-platforms-tumour-killing-abilities [SID1234591147]).

Clinical stage oncology company Prescient Therapeutics (ASX:PTX) will present pre-clinical data on its OmniCAR platform at a key international cell and gene conference.

OmniCAR was developed to overcome challenges and limitations of CAR-T treatments – a new type of intervention used in immunotherapy and cancer treatment.

Prescient Director of Scientific Affairs Dr Rebecca Lim said the latest results demonstrate important capabilities of OmniCAR to deliver next generation cell therapies that are controllable and able to target multiple cancer antigens.

These are key milestones for Prescient’s in-house OmniCAR programs as well as in the development of the overall platform and for potential partners and collaborators.

It is these crucial milestones which will be presented at the Cell & Gene Meeting on the Mesa in Carlsbad, California in the coming days. The conference brings together international senior executives and decision makers on therapies, including cell therapy.

The company’s most recent work, conducted in collaboration with the Peter MacCallum Cancer Centre in Melbourne, showed that OmniCAR-T cells begin antigen-directed killing of tumour cells in vitro as soon as they are armed.

"The team also showed that OmniCAR-T cells could be re-armed and continue to kill tumour cells without loss of cytotoxicity," Lim said.

"Excitingly, we saw for the first time the real-time ‘switchability’ of the OmniCAR system where the tumour killing ability of the OmniCAR-T cells could be redirected towards a different antigen through the addition of a different binder.

"These early wins are extremely encouraging, and we look forward to the next phase of pre-clinical testing where the OmniCAR technology will be put through its paces using gold standard cancer models."

OmniCAR aims to overcome major CAR-T therapy obstacle
A dose response relationship is the correlation between the amount of drug given and magnitude of response. In conventional pharmacology, dose responses are typically straightforward to establish, with typically higher doses leading to greater effects.

However, in cell therapies such as CAR-T therapy, where living cells that continue to grow and divide are administered to patients, effects are considerably less predictable and controllable.

OmniCAR aims to overcome this challenge by combining the potent cytotoxicity of cell therapy with the control and predictability of a conventional drug.

Prescient conducted treatment of glioblastoma multiforme (GBM) cells with OmniCAR-T cells armed with varying amounts of SpyTagged EGFRviii and Her2 binders to test whether different doses of binders resulted in commensurate levels of CAR-T activity.

In both cases, OmniCAR showed dose-dependent tumour killing activity, with the ability to control OmniCAR-T cell activity proportional with the amount of binder administered.

Furthermore, this version of OmniCAR, employing version 3 of the SpyTag/SpyCatcher (ST/SC) system, demonstrated especially high potency, with 60-fold less binder, which has implications for further improving patient safety and lowering cost of goods.

Re-arming capability of OmniCAR a game-changer in CAR-T cell treatment
Single infusions of CAR-T cells may be insufficient to drive meaningful patient outcomes in many cancers, especially solid tumours. Whilst some CAR-T studies have demonstrated clinical efficacy in stubborn cancers with up to seven separate infusions of CAR-T cells, the time, cost, logistics and patient requirements of this approach is prohibitive.

In contrast, achieving ongoing control of T cell activity through complete control of binder administration is viable, logistically undemanding, and inexpensive. Moreover, this method is identical to infusions of biological therapeutics used routinely in clinical practice today.

Prescient has demonstrated the re-arming capability of OmniCAR. OmniCAR-T cells pre-armed with Her2 binders demonstrated potent ability to kill cancer cells expressing Her2.

The cells were then washed and rested for seven days, resulting in unarmed OmniCAR cells. These same OmniCAR-T cells were then capable of being re-armed with Her2 binders, and once again demonstrated targeted killing.

Furthermore, the re-armed cells exhibited the same levels and kinetics of cytotoxicity of pre-armed OmniCAR-T cells, demonstrating that OmniCAR cells can be unarmed, re-armed and still kill.

Treatment hope for GBM brain cancer
Glioblastoma (GBM) is a fast-growing and aggressive brain tumor, characterised by antigen heterogeneity and rapid mutations that drive rapid progression of disease.

These characteristics present significant challenges for therapies, including CAR-T therapies, that rely on single antigen targeting. However, Prescient is seeking to overcome these limitations and provide more effective treatment with the development of OmniCAR to enable multi-antigen targeting.

Prescient has now demonstrated a unique feature of OmniCAR to redirect a single cell product from one cancer antigen to another in GBM cells.

In a novel experiment, OmniCAR was tested sequentially against a co-culture of GBM cells expressing antigens Her2 or EGFRviii. OmniCAR-T cells pre-armed with EGFRviii binders demonstrated rapid cytotoxicity against those GBM cells expressing EGFRviii.

Prescient still to discover true powers of OmniCAR
Prescient Managing Director and CEO Steven Yatomi-Clarke the company looks forward to presenting their data at Cell & Gene Meeting to prominent companies in the field.

"It is very pleasing to see a large body of work accomplished successfully so quickly and is a credit to the Prescient team and the incredible collaborators at Peter MacCallum Cancer Centre," he said.

"Importantly, none of these tests have even been optimised, so we have yet to see the true limits of this technology.

"OmniCAR is proving to be a predictable and powerful system to work with and we look forward to sharing updates as our programs progress."

Prescient’s drug therapy PTX-100 also shows promise
Meanwhile Prescient’s cancer-fighting drug therapy PTX-100 is also showing significant promise for the company, with early stage trials showing benefit to patients with hard to treat cancers.

PTX-100 works by blocking an important protein known as GGT-1 that is involved in cancer-causing pathways in cells.

The drug was well-tolerated, even at the highest dose, with its safety profile meaning it might benefit fragile patients unable to tolerate more toxic therapies, or as a combination agent with other treatments.

Shares in Prescient continue to rise on its promising results, up 11% at the time of writing to 25 cents.

The company will be hosting an ‘OmniCAR Explainer’ session next Tuesday 19th October at 11am (AEDT) where they will discuss the results in more detail. Click here to book in.

FDA Authorizes Sorrento Phase 2 Trial of Epidural Resiniferatoxin for the Orphan Indication of Control of Intractable Cancer Pain

On October 13, 2021 Sorrento Therapeutics, Inc. (NASDAQ: SRNE, "Sorrento") reported that the company has received FDA clearance to proceed with a global Phase 2 clinical study of resiniferatoxin (RTX), entitled "A Multicenter, Phase 2 Study to Assess the Safety and Efficacy of Epidural Resiniferatoxin for the Treatment of Intractable Pain Associated with Advanced Cancer" (Press release, Sorrento Therapeutics, OCT 13, 2021, View Source [SID1234591168]). The Phase 2 trial, a multi-center, double blind, controlled study will assess the "efficacy and safety of several RTX doses vs. placebo controls to manage intractable pain in up to 120 patients with advanced cancer" (NCT05067257). Three RTX dose groups (15, 20 and 25 mcg) will be evaluated against both a vehicle control group and a concurrent control group over a year of follow up. The primary objective of the study is to identify the recommended Phase 3 dose for later studies.

The decisions related to this indication follow the analysis of the significant observations from the Phase 1b trial results (NCT03226574). The Phase 1 was an ascending dose safety study in 17 patients to assess the safety and preliminary efficacy of epidural administration of resiniferatoxin for the treatment of intractable pain due to cancer. RTX was generally well tolerated after epidural administration at doses up to 30 mcg with the most common adverse event of "procedural pain" experienced by just over half of subjects (52.9%) and all of these events were considered at most moderate severity and lasted only a few hours. Pharmacokinetic sampling showed no measurable systemic RTX levels in nearly all subjects. Preliminary efficacy showed promising long-standing benefit in pain reduction.

In the Phase 1 study, clinical efficacy was defined as a 30% decrease in average pain scores (CE30), calculated for both average pain for three consecutive days from original baseline score of ≥ 6 on a scale of 1 to 10 (NRS rating scale) and worst average pain, compared to baseline using the NRS during the 3 months post injection. Eleven of 17 subjects achieved this efficacy endpoint with subjects receiving 15 or 25 mcg showing the best results. For CE50 and CE70, 6 and 4 subjects, respectively, achieved these endpoints again with those receiving 15 or 25 mcg showing best results. These results are promising in view of the challenging, intractable pain conditions due to advanced cancer, however the somewhat small sample size enrolled requires confirmation in larger follow-on studies.

About Resiniferatoxin (RTX)

Resiniferatoxin is a small-molecule derivative (diterpene ester), purified from a cactus-like plant (Euphorbia sp.). It is a highly potent agonist of the transient receptor potential vanilloid-1 (TRPV1) receptor which are specifically upregulated with chronic severe noxious pain. A thousand times "hotter" than pure capsaicin (16 billion Scoville units versus 16 million), and with a high affinity for afferent sensory pain nerves, resiniferatoxin binds to TRPV1 receptors and selectively ablates the neurons responsible for perpetuating chronic severe pain signals experienced by patients.

More information on this trial can be found at www.clinicaltrials.gov (NCT03542838).

NeoImmuneTech Announces First Patient Dosed in Phase 1b Study of NT-I7 (efineptakin alfa) and Kymriah® (tisagenlecleucel) in Relapsed/Refractory Large B-Cell Lymphoma

On October 13, 2021 NeoImmuneTech, Inc. (KOSDAQ: 950220), a clinical-stage T cell-focused biopharmaceutical company, reported that the first patient has been dosed in a Phase 1b study of its lead drug candidate, NT-I7 (efineptakin alfa), a novel long-acting human interleukin-7 (IL-7), following CAR-T cell therapy tisagenlecleucel (Kymriah) in patients with relapsed/refractory (r/r) Large B-Cell Lymphoma (LBCL) (Press release, NeoImmuneTech, OCT 13, 2021, View Source [SID1234591188]).

Diffuse Large B-Cell Lymphoma (DLBCL) is the most commonly occurring subtype of Non-Hodgkin Lymphoma (NHL), accounting for 25% to 30% of all NHL and >20,000 cases in the U.S. annually1. Despite improvement in therapeutic options, treatment is often not curative with as many as 50% of patients developing relapsed or refractory disease2.

"We have shown in multiple animal models that the addition of NT-I7 to CAR-T cells substantially increased CAR-T cell proliferation, persistence, and target-specific tumor killing, resulting in significantly prolonged survival of the treated animals," said NgocDiep Le, M.D., Ph.D., Executive VP and Chief Medical Officer of NeoImmuneTech (NIT). "Now that we have begun dosing in this study, we look forward to evaluating the potential of NT-I7 therapy to prolong clinical response and survival for patients with r/r LBCL."

Se Hwan Yang, Ph.D., President and Chief Executive Officer of NIT added, "While CAR-T cell therapies have revolutionized the way we treat multiple hematologic malignancies, relapsed or refractory illness still impacts many patients with LBCL who are in need of additional treatment options. By advancing this Phase 1b study, we hope to pave the way for a new therapeutic solution that could enhance the clinical impact of Kymriah alone and ultimately improve patient outcomes."

This multicenter Phase 1b study will evaluate the safety, tolerability, and preliminary anti-tumor activity of NT-I7 administration following standard-of-care tisagenlecleucel CAR-T cell therapy, and determine the recommended Phase 2 dose of the combination for further future clinical development.

About NT-I7

NT-I7 (efineptakin alfa) is the only clinical-stage long-acting human IL-7, and is being developed for oncologic and immunologic indications, in which T cell amplification and enhanced functionality may provide clinical benefit. IL-7 is a fundamental cytokine for naïve and memory T cell development and for sustaining immune response to chronic antigens (as in cancer) or foreign antigens (as in infectious diseases). In clinical trials to date, NT-I7 has exhibited favorable PK/PD and safety profiles, both as a monotherapy and in combination with other anticancer treatments. NT-I7 is being studied in multiple clinical trials in solid tumors and as a vaccine adjuvant. Studies are being planned for testing in hematologic malignancies, additional solid tumors and other immunology-focused indications.
