"Optogenetics is emerging as a promising therapeutic approach that might restore sight to patients who are legally blind," said Jay Bradner, President of the Novartis Institutes for BioMedical Research. "The Arctos technology builds on our conviction that optogenetic gene therapies may meaningfully help patients battling devastating eye diseases."

Arctos developed its technology as a potential method for treating inherited retinal dystrophies (IRDs) and other diseases that involve photoreceptor loss, such as age-related macular degeneration (AMD). Existing gene therapy treatments aim to correct a specific gene, so only a small subset of patients can benefit. The Arctos technology is not limited to a specific gene, and thus can potentially address many forms of IRDs regardless of the underlying mutation. Arctos’ proprietary, light-sensitive optogene is delivered to specific retinal cells using gene therapy, thus turning the targeted cells into replacement photoreceptor-like cells. If successful, a therapeutic based on such a technology could be used to treat any disease that causes blindness due to photoreceptor death.

"We’ve watched this technology develop and mature into a therapeutic program that complements our existing portfolio and gives us new optogenetics technology to wield in our efforts to bring desperately needed therapeutic options to patients for these blinding diseases," said Cynthia Grosskreutz, Global Head of Ophthalmology at the Novartis Institutes for BioMedical Research.

IRDs, which impact more than 2 million people globally and often result in complete blindness, can be caused by mutations in over 100 different genes.1 AMD is the leading cause of visual disability, affecting an estimated 170 million people globally.2 There are no curative therapies currently available for AMD.

The Arctos technology was based on discoveries by its scientific co-founders Drs. Sonja Kleinlogel and Michiel van Wyk of University of Bern, Switzerland. Arctos was originally incubated by +ND Capital and was later supported by Novartis Venture Fund through a Series A financing round led by +ND Capital.

On September 21, 2021 Vivoryon Therapeutics N.V.

"In the first half of 2021, we made significant progress towards bringing our lead candidate varoglutamstat to patients suffering from Alzheimer’s disease. Despite the ongoing pandemic, recruiting into our European Phase 2b study VIVIAD is on track and we’re particularly excited about the initiation of our complementary Phase 2 study VIVA-MIND in the US. Furthermore, by entering into a strategic regional partnership with Simcere, we have made substantial headway towards making varoglutamstat available to AD patients in China in the future," said Dr. Ulrich Dauer, CEO of Vivoryon. "Beyond AD, we are pleased to see our diverse preclinical pipeline of oral small molecule inhibitors maturing in a number of indications with exceptionally high medical need."

Corporate Highlights and R&D Updates
Varoglutamstat

Vivoryon’s US Phase 2a/b VIVA-MIND study for varoglutamstat in patients with early AD is being initiated as planned. VIVA-MIND is a combined Phase 2a/b study expecting to enroll 180 patients into the Phase 2a adaptive dose finding part, with an interim futility analysis planned for H1/2023. If predefined criteria are fulfilled, the trial is stage-gated into the Phase 2b part, enrolling an additional 234 patients treated at the selected dose for ³72 weeks. The primary endpoint for this study is CDR-SB (clinical dementia rating scale – sum of boxes), an established approvable endpoint measuring a combination of cognitive abilities and activities of daily living. The VIVA-MIND study is sponsored by Vivoryon and the study director is Dr. Howard Feldman, Professor of Neurosciences and Director of the Alzheimer’s Disease Cooperative Study (ADCS) at the University of California San Diego School of Medicine. The study is coordinated by the ADCS, and supported by the National Institute on Aging (NIA), part of the National Institutes of Health (NIH) (NIA award number R01AG061146). The study’s first site is now approved to initiate screening of its first participant.
On June 29, 2021, Vivoryon and Simcere Pharmaceutical Group Ltd announced that they have entered into a strategic regional licensing partnership to develop and commercialize medicines targeting the neurotoxic amyloid species N3pE (pGlu-Abeta) to treat AD in Greater China. The agreement grants Simcere a regional license to develop and commercialize varoglutamstat (PQ912), Vivoryon’s Phase 2b-stage N3pE amyloid-targeting oral small molecule glutaminyl cyclase (QPCT) inhibitor with disease-modifying potential for AD, as well as the Company’s preclinical monoclonal N3pE‑antibody PBD-C06 in the Greater China region.
Enrollment into the ongoing European Phase 2b VIVIAD study in patients with mild cognitive impairment (MCI) and mild AD is on track, with an interim safety readout anticipated in mid-2022. A number of additional study centers were opened to balance the effects of COVID-19 related patient and staff protection policies implemented at German study sites. Details on the study led by Prof. Dr. Philip Scheltens, University Medical Center, Amsterdam, were recently published in a peer-reviewed journal as Vijverberg et al., Alzheimer’s Research & Therapy (2021) 13:142 (View Source).
Patent Portfolio

Throughout the first half of 2021, Vivoryon has significantly expanded its patent portfolio with eight additional patents granted for the Company’s small molecule inhibitors and antibody-based medicines in development to treat AD and other diseases with exceptionally high medical need. Year to date (as of September 21, 2021) a total of 14 additional patents have been granted.

Financial Results for the First Six Months of 2021
In the first two quarters of 2021, research and development expenses amounted to EUR 9,456 k (H1 2020: EUR 6,380 k). This increase was mainly driven by higher expenses for production (H1 2021: EUR 4,194 k, H1 2020: EUR 1,876 k), expenses for share-based payments (H1 2021: EUR 464 k, H1 2020: EUR 3 k) and higher costs associated with basic research projects in connection with Meprin (H1 2021: EUR 220 k, H1 2020: nil) and cancer (H1 2021: EUR 162 k, H1 2020: nil).

General and administrative expenses increased to EUR 2,337 k (H1 2020: EUR 1,138 k). This increase is largely attributable to costs for consulting (H1 2021: EUR 1,030 k, H1 2020: EUR 481 k) and expenses for share based payments (2021: EUR 464 k, 2020: nil). The increase in consulting costs resulted from the transformation of the Company’s legal form, subsequent adaption of administrative structures and preparations for potential future capital measures.

The Company did not generate any licensing revenues in the reporting period. Revenues deriving from the strategic regional licensing partnership with Simcere will be recognized starting in the third quarter of 2021.

Net loss of the period was EUR 11,671 k compared to EUR 7,572 k in the first half of 2020.

The Company held EUR 19,832 k in cash and cash equivalents as of June 30, 2021, compared to EUR 26,306 k as of December 31, 2020.

Pr. Benjamin Besse, Director of Clinical Research at Gustave Roussy (Villejuif, France), and Principal Investigator of the Atalante 1 study, commented: "There was a lot learned during this trial about Tedopi and its potential clinical benefit that will help inform future studies in the immunotherapy field. Applying the 2020 SITC (Free SITC Whitepaper)(2) guidelines defining resistance categories for PD-1/PD-L1 checkpoint inhibitors to our trial, developed while this trial was ongoing, suggest there is great potential for Tedopi in patients with secondary resistance(3) . Therefore, we are very pleased to share such very promising results demonstrating the substantial benefits of Tedopi for NSCLC patients with secondary resistance to anti-PD-1 treatments, a hard to treat patient population with high medical need."

The Atalante 1 clinical trial evaluated the benefit of Tedopi in an HLA-A2 positive patient population with NSCLC at invasive stage IIIB or metastatic stage IV, in 2nd or 3rd line treatment following checkpoint inhibitor failure. The Tedopi treatment was compared to docetaxel or pemetrexed chemotherapy (CT) treatments in this patient population, with overall survival as the primary endpoint of the trial.

The Atalante 1 clinical trial evaluated the benefit of Tedopi in an HLA-A2 positive patient population with NSCLC at invasive stage IIIB or metastatic stage IV, in 2nd or 3rd line treatment following checkpoint inhibitor failure. The Tedopi treatment was compared to docetaxel or pemetrexed chemotherapy (CT) treatments in this patient population, with overall survival as the primary endpoint of the trial.

A total of 219 patients were enrolled in Atalante 1. 183 (84%) of these patients received sequential CTimmunotherapy (IO), of which 118 patients (54%) met the definition of PoI, with otherwise similar other baseline characteristics to the overall Atalante 1 population.

Tedopi demonstrated a favorable benefit/risk ratio versus standard of care (SoC) docetaxel or pemetrexed in advanced HLA-A2+ NSCLC patients with secondary resistance to immune checkpoint inhibitors.

The main results were:
Improved efficacy
1. Overall survival (primary endpoint) was statistically significantly improved for Tedopi: HR=0.59 (95% CI: 0.38, 0.91) in favor of the Tedopi arm. A clinically meaningful gain in median overall survival of 3.6 months in favor of the Tedopi arm with Tedopi OS at 11.1 months versus 7.5 months for SoC (p=0.017).

2. The objective response rate and progression free survival (PFS) were lower in the Tedopi arm, as
expected for a therapeutic vaccine versus a cytotoxic drug while at 6 months, the disease control
rate (DCR) was similar (25 % Tedopi versus 24 % SoC).

3. Post progression survival was also significantly longer in the Tedopi arm (7.7 months versus 4.6 months; p=0.004).

Improved safety profile
1. A good ECOG performance status(5), with time to ECOG deterioration significantly longer in the Tedopi arm (8.6 months versus 3.3 months; p=0.0005).

2. A maintained quality of life was observed with Tedopi (p= 0.04).

3. A good tolerance profile of Tedopi with fewer Severe Adverse Events (Tedopi 38% vs SoC 68%, p<0.001). No Treatment Emergent Adverse Effects of concern in the Tedopi arm.

On September 20, 2021 PharmaMar (MSE:PHM) reported that new data on Yondelis (trabectedin) in patients with metastatic or inoperable leiomyosarcoma will be presented at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) congress, which is being held virtually from 16th to 21st September (Press release, PharmaMar, SEP 20, 2021, View Source [SID1234596669]).

Under the title "LMS-04 study: a randomised, multicenter phase-III study comparing doxorubicin alone versus doxorubicin with trabectedin followed by trabectedin in nonprogressive patients as first-line therapy, in patients with metastatic or unresectable leiomyosarcoma. A French Sarcoma Group study," the French Sarcoma Group will present data from a phase III study comparing first-line treatment with trabectedin in combination with doxorubicin versus standard-o-care single-agent doxorubicin for the first-line treatment of patients with metastatic or unresectable leiomyosarcoma.

The study achieved its primary endpoint of Progression Free Survival (PFS), progression RECIST (Response Evaluation Criteria In Solid Tumors)1 , supplemented by central review. In the combination arm of trabectedin with doxorubicin, median PFS reached 12.2 months, compared to 6.2 months with single-agent doxorubicin (HR = 0.41; 95% CI 0.29-0.58; P<0.0001).

In addition, the Overall Response Rate (ORR) was 38% using the combination, compared to 13% in the comparator arm. Overall Survival (OS) was 30.5 months in patients who received trabectedin in combination with doxorubicin, compared to 24.1 months in patients who received doxorubicin alone.

Patricia Pautier, M.D., oncologist, head of the multidisciplinary committee of gynecologic oncology at Gustave-Roussy and lead author of the study, said: "Leiomyosarcoma has been classically reported as the most frequent soft tissue sarcoma subtype together with liposarcoma, a third of them have a uterine location. Patients have a poor prognosis when leiomyosarcomas are metastatic. In prospective clinical trials, a median PFS of about 6 months and overall survival of around 12–15 months are usually reported for patients treated with any first-line chemotherapy, representing a true unmet medical need. In general, Doxorubicin and Ifosfamide are the backbone of sarcoma treatment, but nor other association nor new therapies are superior to doxorubicin in terms of overall survival." She added: "Trabectedin is known to be active in second line treatment for leiomyosarcomas.

The previous phase II of the trabectedin-doxorubicin combination in metastatic or advanced LMS in first line therapy (LMS02) share very encouraging results in terms of ORR, PFS and OS. The results of the LMS04 study have confirmed that this combination is superior in terms of PFS to doxorubicin alone with a 6 months statistical benefit; the impact on PFS2 also is in favor of the use of the association in combination rather than in a sequential way. There is a clinical impact on overall survival and a longer follow-up will let us know if this therapy will impact overall survival and will be the new standard of treatment in this indication.
