This approval of Penpulimab by the NMPA is based on a multicenter, single-arm, open-label pivotal clinical trial. Patients enrolled were r/r cHL patients who had failed at least second- line systemic chemotherapy and were administered 200 mg Penpulimab monoclonal antibody by intravenous injection once every two weeks until progress is made or reached unacceptable toxicity. The key research endpoint was the objective response rate ("ORR") evaluated by the independent radiology review committee ("IRRC") with reference to the Lugano 2014 lymphoma efficacy rating criteria.

The research shows that:

The ORR assessed by IRRC was 89.4% (76/85) with 47.1% (40/85) patients achieved complete response (CR). The median follow-up time was 15.8 months. The 12-month duration of response ("DoR") was 74.9%. And 12-month progression-free survival ("PFS") was 72.1%.
In terms of safety profile, the median exposure to Penpulimab antibody was 14.8 months, and 76.6% of patients were treated with Penpulimab antibody for 12 months or longer. Serious adverse events ("SAEs") associated with Penpulimab antibody was 10.6%, with no more than one patient experiencing a drug-related SAE. 26.6% of Grade 3 or higher adverse reactions had occurred, with equal to or greater than 2% of rash, hyperlipidemia, and lung infection. 4.3% of Grade 3 immune-related adverse events ("irAEs") had occurred, with no Grade 3 or higher irAEs.
Penpulimab is currently the only new PD-1 monoclonal antibody that applies IgG1 subtype and is modified by Fc segment, which has a lower antigen binding dissociation rate and a unique binding epitope as demonstrated by analysis on crystal structure. These features allow Penpulimab to effectively and continuously block PD-1/PD-L1 binding, thus differentiates it from other PD-1 products on the market, and may allow Penpulimab to more effectively enhance immunotherapeutic efficacy and reduce immune-related adverse reactions, as demonstrated by improved safety profile in clinical data.

Penpulimab is Akeso’s first innovative antibody protein drug that has been granted marking approval with major research studies covering major oncology diseases such as liver cancer, gastric cancer, lung cancer, Hodgkin’s lymphoma and nasopharyngeal carcinoma. In addition to the said approval for the treatment of cHL, Penpulimab has submitted 2 NDAs in China and 1 biologics license application ("BLA") in the U.S.:

In August 2021, NDA of Penpulimab for third-line treatment of metastatic nasopharyngeal carcinoma was submitted and was accepted by the NMPA.

In July 2021, NDA of Penpulimab for combined chemotherapy for first-line treatment of locally advanced or metastatic squamous non-small-cell lung cancer was submitted and was accepted by the NMPA.

In May 2021, Penpulimab for third-line treatment of metastatic nasopharyngeal carcinoma has been submitted to the Food and Drug Administration of the United States (FDA) for a BLA through the Real-Time Oncology Review (RTOR) program.

On August 6, 2021 BioInvent International AB ("BioInvent") (Nasdaq Stockholm: BINV) reported that it has entered into a second clinical trial collaboration and supply agreement with MSD, a tradename of Merck & Co., Inc., Kenilworth, NJ., USA, to evaluate the combination of BioInvent’s BI-1808, one of its proprietary anti-TNFR2 antibodies and MSD’s anti-PD-1 therapy, KEYTRUDA in a Phase 1/2a clinical trial for patients with lung cancer and ovarian cancer (Press release, BioInvent, AUG 6, 2021, View Source [SID1234586028]).

"We are very pleased we have reached a second collaboration with MSD that supports the expansion of the clinical trial program with our anti-TNFR2 antibody BI-1808. The Phase 1 component is already enrolling patients who receive BI-1808 as a single agent. We are excited about the potential synergistic activity of BI-1808 in combination with pembrolizumab and this agreement supports the strong interest elicited by our broadening pipeline of anti-cancer antibodies," said Martin Welschof, CEO of BioInvent.

The Phase 1/2a trial explores the potential of BI-1808 to treat patients with ovarian cancer and non-small cell lung cancer both as a single agent and in combination with KEYTRUDA. A separate cohort in the Phase 2a component will explore the activity of BI-1808 as a single agent in cutaneous T cell lymphoma. It is planned to perform the trial in the U.S., Denmark, Hungary, the United Kingdom, and Russia. Patient enrollment is already taking place in several European countries.

The anti-TNFR2 antibody BI-1808 is part of BioInvent’s tumor-associated regulatory T cells (Treg)-targeting program, which has emerged from its F.I.R.S.T platform technology that simultaneously identifies targets and high-quality antibodies, generating promising new drug candidates to target the tumor microenvironment. TNFR2 is particularly upregulated on Tregs and has been shown to be important for tumor expansion and survival, representing a new and important target for cancer immunotherapies.

KEYTRUDA is a registered trademark of Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc., Kenilworth, NJ, USA.

On August 6, 2021 Immunic, Inc. (Nasdaq: IMUX), a clinical-stage biopharmaceutical company developing a pipeline of selective oral immunology therapies focused on treating chronic inflammatory and autoimmune diseases, reported financial results for the second quarter ended June 30, 2021 and highlighted recent activity (Press release, Immunic, AUG 6, 2021, View Source [SID1234586027]).

"So far this year, we have made outstanding progress with both our selective oral DHODH inhibitor, IMU-838, as well as IMU-935, a highly potent and selective inverse agonist of the transcription factor RORγt, enabling what we believe will be an eventful and potentially transformative first half of 2022. In particular, we anticipate five data read-outs from clinical trials within the next twelve months, and expect to begin our first phase 3 program very soon. I want to congratulate our entire team for this remarkable momentum," stated Daniel Vitt, Ph.D., Chief Executive Officer and President of Immunic. "In June, we received U.S. Food and Drug Administration (FDA) clearance for our Investigational New Drug (IND) application for the phase 3 ENSURE program of IMU-838 in patients with relapsing-remitting multiple sclerosis (RRMS), and the supportive phase 2 CALLIPER trial in patients with progressive multiple sclerosis (PMS). Initiation of these trials in the second half of this year will mark a major milestone for our lead program. Additionally, we look forward to completing recruitment of our ongoing phase 2 CALDOSE-1 trial of IMU-838 in patients with ulcerative colitis (UC) during the second half of 2021, and reporting top-line data for this potential second key indication for IMU-838 in the first half of 2022."

"At our virtual R&D Day just last month, we presented very encouraging in vitro data showing that IMU-935 may inhibit both the generation of Th17 cells and the production of IL-17 cytokines that are responsible for the development of autoimmune diseases, without impairing thymocyte development, thereby avoiding a potential risk for lymphoma that has complicated third-party programs in this space. We also detailed highly encouraging new preclinical data which suggests that IMU-935 can affect castration-resistant prostate cancer (CRPC) both directly by reducing androgen receptor (AR) expression via RORγ and inhibiting tumor growth, and indirectly by inhibiting tumorigenesis-promoting Th17 and IL-17. Based on the strength of this data, we are preparing a phase 1 trial in metastatic CRPC (mCRPC) patients with Johann Sebastian de Bono, M.D., Ph.D., Regius Professor of Cancer Research and Professor in Experimental Cancer Medicine, The Institute of Cancer Research and The Royal Marsden NHS Foundation Trust, London, United Kingdom, acting as the Principal Investigator. We expect this trial to commence during the fourth quarter of this year and also anticipate availability of initial human data from moderate-to-severe psoriasis patients from our phase 1 trial of IMU-935 during the second quarter of 2022."

Dr. Vitt added, "As previously announced, at the end of the first quarter of 2021, we settled our remaining royalty obligation to 4SC AG for both IMU-838 and IMU-935, for $17.3 million, which was paid 50% in cash and 50% in shares of Immunic’s common stock during the second quarter. This strategic decision provides us with 100% of the future sales potential of our two lead programs and should drive significant value for our shareholders. Last month, we were able to offset this payment by bolstering our balance sheet with a $45.0 million financing, providing us with anticipated runway through multiple value inflection points into 2023."

Second Quarter 2021 and Subsequent Highlights

July 2021: Completed a $45.0 million underwritten public offering of common stock.
July 2021: Hosted a virtual R&D Day to provide an update on the preclinical and clinical development of IMU-935, including:
Based on preclinical studies performed by Immunic, as well as third-party research, the company believes that IMU-935’s observed selectivity may enable it to inhibit the generation of Th17 cells and the production of IL-17 cytokines without impairing RORγt function required for normal thymocyte development and may, therefore, avoid the risk of T cell malfunction and potential lymphoma formation seen in third-party RORγt programs.
In preclinical studies, IMU-935 was observed to suppress the expression of mutated AR-V7 in prostate cancer cell lines, thus potentially inhibiting tumor growth in CRPC patients who are insensitive to androgen-targeted therapies. By suppressing the expression of pro-tumorigenic IL-17, IMU-935 may also inhibit tumorigenesis in an indirect fashion. Based on these results, the company is currently preparing an open-label phase 1 dose escalation trial designed to establish a recommended phase 2 dose and to assess safety, tolerability, anti-tumor activity, biomarkers and pharmacokinetics (PK) of IMU-935 in patients with progressive mCRPC.
The full PK and blinded safety data from the completed single ascending dose (SAD) part of the phase 1 trial of IMU-935 was made available. The data set revealed dose-linear PK and a blood half-life that may be appropriate for once or twice daily dosing. Although the trial is still blinded, no significant safety findings have been detected in the SAD cohorts, to date.
June 2021: Announced FDA clearance of the company’s IND application to begin the phase 3 ENSURE program, comprised of two multicenter, randomized, double-blind trials designed to evaluate the efficacy, safety, and tolerability of IMU-838 versus placebo in RRMS patients. Additionally, announced FDA clearance of a separate IND application to initiate the supportive, multicenter, randomized, double-blind, placebo-controlled phase 2 CALLIPER trial of IMU-838 in patients with PMS, which will run concurrently with the phase 3 program in RRMS and which is designed to corroborate IMU-838’s neuroprotective potential.
June 2021: Announced the appointment of Inderpal Singh as General Counsel. Mr. Singh is responsible for legal and compliance matters and has become part of the management team of the company.
April 2021: Announced interim data from the 10 mg Cohort 2 of the EMPhASIS trial of IMU-838 in RRMS confirming, along with previously published data from Cohort 1, that the 30 mg once daily dosing of IMU-838 is the most appropriate dose for the company’s phase 3 program in RRMS. The experimental part of double-blind treatment in Cohort 2 has meanwhile been completed.
Anticipated Clinical Milestones

IMU-838 in RRMS: The twin, multicenter, randomized, double-blind, phase 3 ENSURE-1 and ENSURE-2 trials of 30 mg daily IMU-838 or placebo will run concurrently. Dosing of the first patient is expected in the second half of 2021.
IMU-838 in PMS: The multicenter, randomized, double-blind, phase 2 CALLIPER trial of 45 mg daily IMU-838 or placebo is intended to run concurrently with and to complement the phase 3 program in RRMS. Dosing of the first patient is expected in the third quarter of 2021.
IMU-838 in UC: Recruitment of the phase 2 CALDOSE-1 trial of IMU-838 in patients with UC is expected to be completed in the second half of 2021 and top-line data of the induction phase is expected to be available in the first half of 2022, as previously announced.
IMU-935 phase 1 program in healthy volunteers and psoriasis patients: The multiple ascending dose (MAD) part of the phase 1 trial of IMU-935 is ongoing and progressing. Unblinded safety, pharmacodynamic and PK data from the SAD and MAD parts in healthy volunteers is expected to be available in the second half of 2021. Initiation of the third portion of the phase 1 trial in patients with moderate-to-severe psoriasis is expected in the third quarter of 2021 and initial human data from this patient population is expected to be available in the second quarter of 2022.
IMU-935 phase 1 trial in CRPC patients: An open-label phase 1 dose escalation trial designed to establish a potential recommended phase 2 dose and to assess safety, tolerability, anti-tumor activity, biomarkers and PK of IMU-935 in patients with progressive mCRPC, is expected to commence in the fourth quarter of 2021.
IMU-856 phase 1 program: The SAD part of the ongoing phase 1 trial of IMU-856 has been completed. Based on the favorable data available so far, the company expects to receive clearance from the Ethics Committee in Australia to proceed to the MAD part in healthy volunteers, in the near future. Unblinded safety data from the SAD and MAD parts in healthy volunteers is expected to be available in the first quarter of 2022. Initiation of the third portion of the phase 1 trial in patients with several diseases involving bowel barrier dysfunction is expected in the first half of 2022.

"Our second quarter accomplishments have advanced our lead clinical breast cancer program down a clear path towards a registrational study and substantially de-risked our broader clinical pipeline," said Dr. Matt Coffey, President and Chief Executive Officer of Oncolytics Biotech Inc. "Clinical AWARE-1 data show that pelareorep is an immunotherapeutic agent that synergistically combines with checkpoint inhibitors. These findings support the statistically significant overall survival benefit observed in our prior phase 2 breast cancer trial, achieving a key regulatory objective. They also suggest that pelareorep’s efficacy can be further enhanced by combining it with checkpoint inhibition. We are currently working to confirm this hypothesis in the BRACELET-1 breast cancer trial, which will support pelareorep’s advancement to a registrational study."

Dr. Coffey continued, "Beyond our lead program, we also presented clinical proof-of-concept data in pancreatic cancer that further demonstrate pelareorep’s immunologic mechanism of action and potential to address unmet needs across multiple indications. Together with AWARE-1 data, these results support our ongoing trials evaluating pelareorep-checkpoint inhibitor combinations and highlight pelareorep’s potential as an enabling technology for multiple classes of immunotherapeutic agents. Looking forward, our strong financial foundation leaves us well-positioned to build on this momentum and advance pelareorep’s clinical development. As we work towards this goal, we will remain primarily focused on breast cancer and our stated clinical milestones while pursuing a partnership strategy to further broaden pelareorep’s potential impact."

Second Quarter and Subsequent Highlights

Breast Cancer Program

Achieved primary endpoint in AWARE-1 study

Data from the twenty HR+/HER2- early-stage breast cancer patients included in AWARE-1’s first two cohorts were presented in an electronic poster at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2021 (link to PR; link to poster). Results from these patients, who were treated with pelareorep and letrozole without (cohort 1) or with (cohort 2) the PD-L1 inhibitor atezolizumab (Tecentriq), showed that that pelareorep and letrozole treatment upregulated tumor PD-L1 expression, induced the generation and expansion of T cell clones, promoted tumor infiltration of CD8+ T cells, and increased CelTIL score, a measure of tumor cellularity and inflammation that is significantly correlated with event-free and overall survival. These desirable effects were further enhanced in patients receiving atezolizumab, demonstrating that pelareorep and atezolizumab synergistically combine to generate an anti-cancer immune response in the tumor and peripheral blood. Notably, cohort 2 met the pre-specified success criteria for the study’s primary endpoint, with six of ten patients achieving at least a 30% increase in CelTIL score following treatment. Together, these data support the results of a prior successful phase 2 trial (IND-213) that showed a statistically significant near doubling of overall survival with pelareorep treatment. This supports the clinical rationale behind the phase 2 BRACELET-1 trial: Evaluating the safety and efficacy of pelareorep and chemotherapy alone, and in combination with a PD-L1 inhibitor, in HR+/HER2- breast cancer patients.

Gastrointestinal Cancers Program

Phase 2 data demonstrating clinical proof-of-concept for pelareorep-checkpoint inhibitor combination therapy in pancreatic cancer

Data from a phase 2 trial evaluating pelareorep in combination with the PD-1 inhibitor pembrolizumab (KEYTRUDA) in pancreatic adenocarcinoma patients who progressed after first-line treatment were featured in an electronic poster presentation at the 2021 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting (link to PR; link to poster). Findings from the trial indicate that pelareorep and pembrolizumab synergize and show anti-cancer activity in these difficult-to-treat patients, with a 42% disease control rate achieved and durations of control ranging from approximately 2.5 months to approximately 7 months despite the absence of chemotherapy in the treatment regimen. Biomarker data showed that patients achieving disease control had increased activation of anti-cancer CD8+ T cells in the peripheral blood, and reduced levels of pro-tumor Treg cells in the peripheral blood and tumor compared to those with progressive disease. These results, which are consistent with what has been seen in clinical trials in other indications, such as breast cancer, highlight the broad applicability of pelareorep’s immunotherapeutic mechanism of action. They also bode well for a successful outcome in the phase 1/2 GOBLET trial, which includes a cohort evaluating pelareorep and the PD-L1 inhibitor atezolizumab in combination with chemotherapy as a first-line treatment in metastatic pancreatic cancer patients (link to PR).

Additional Immunotherapeutic Combinations and Opportunities

Preclinical data highlighting pelareorep’s ability to synergize with multiple classes of anti-cancer agents

Data presented in two electronic poster presentations at the AACR (Free AACR Whitepaper) Annual Meeting 2021 showed that pelareorep enhanced the anti-tumor efficacy of the poly(ADP)-ribose polymerase 1 (PARP-1) inhibitor talazoparib and the cyclin-dependent kinase (CDK) 4/6 inhibitor palbociclib, which are both FDA approved for the treatment of breast cancer. The observed synergistic effects were notably mediated through immunologic mechanisms rather than through the molecular pathways typically associated with PARP-1 and CDK4/6 inhibition (link to PR; link to CDK4/6 poster; link to PARP-1 poster). Together, these results suggest that pelareorep may enhance the therapeutic potential of PARP-1 and CDK4/6 inhibitors by expanding the mechanisms by which they exert anti-tumor effects.

Changes to the Board of Directors

William G. Rice, Ph.D. has stepped down from Oncolytics Biotech’s Board of Directors to avoid any potential conflicts that might arise from the development of pelareorep with molecules being developed by Aptose Biosciences Inc., the company for which Dr. Rice serves as Chairman of the Board, President & Chief Executive Officer. "I’m a staunch supporter of Oncolytics and wish to express my sincere gratitude for the time serving the Board and working with a wonderful group of directors and officers," stated Dr. Rice. Oncolytics would like to thank Dr. Rice for his guidance during his tenure as a member of the Board.

Cohort 5 (n=6), HR- / HER2+ (pelareorep + trastuzumab + atezolizumab)
The study combines pelareorep, without or with atezolizumab, and the standard of care therapy according to breast cancer subtype. Tumor tissue is collected from patients as part of their initial breast cancer diagnosis, again on day three following initial treatment, and finally at three weeks following treatment, on the day of their mastectomy. Data generated from this study are intended to confirm that pelareorep is acting as a novel immunotherapy, to evaluate potential synergy between pelareorep and checkpoint blockade, and to provide comprehensive biomarker data by breast cancer subtype. The primary endpoint of the study is overall CelTIL score (a measurement of cellularity and tumor-infiltrating lymphocytes). Secondary endpoints for the study include CelTIL by breast cancer subtype, safety, and tumor and blood-based biomarkers.

About BRACELET-1

The BRACELET-1(BReast cAnCEr with the Oncolytic Reovirus PeLareorEp in CombinaTion with anti- PD-L1 and Paclitaxel) study is an open-label, phase 2, randomized study in patients with HR+/HER2-, endocrine-refractory metastatic breast cancer being conducted under a co-development agreement with Merck KGaA, Darmstadt, Germany and Pfizer. PrECOG LLC, a leading cancer research network, is managing the study. The study will take place at 20 trial sites and is expected to enroll 45 patients randomized into three cohorts. A three-patient safety run-in was conducted with patients receiving pelareorep, paclitaxel, and avelumab prior to randomization. The three cohorts being treated are as follows:

Cohort 1 (n=15): paclitaxel
Cohort 2 (n=15): paclitaxel + pelareorep
Cohort 3 (n=18): paclitaxel + pelareorep + avelumab (Bavencio)
Patients in cohort 1 will receive paclitaxel on days 1, 8, and 15 of a 28-day cycle. Patients in cohort 2 will receive the same paclitaxel regimen as cohort 1, plus pelareorep on days 1, 2, 8, 9, 15 and 16 of the 28-day cycle. Patients in cohort 3 will receive the same combination and dosing regimen as cohort 2, plus avelumab on days 3 and 17 of the 28-day cycle. The primary endpoint of the study is overall response rate. Exploratory endpoints include peripheral and tumor T cell clonality, inflammatory markers, and safety and tolerability assessments.

The GOBLET (Gastrointestinal tumOrs exploring the treatment comBinations with the oncolytic reovirus peLarEorep and anTi-PD-L1) study is a phase 1/2 multiple indication biomarker, safety, and efficacy study in advanced or metastatic gastrointestinal tumors. The study will be conducted at 15 centers in Germany. The primary endpoint of the study is safety, with overall response rate and biomarker evaluation (T cell clonality and CEACAM6) as exploratory endpoints. Approximately 55 patients are planned to be enrolled in four independent cohorts:

Pelareorep in combination with atezolizumab, gemcitabine, and nab-paclitaxel in 1st line metastatic pancreatic cancer patients (n=12);
Pelareorep in combination with atezolizumab in 1st line MSI (microsatellite instability)-high metastatic colorectal cancer patients(n=19);
Pelareorep in combination with atezolizumab and TAS-102 in 3rd line metastatic colorectal cancer patients (n=14); and
Pelareorep in combination with atezolizumab in 2nd line advanced and unresectable anal cancer patients (n=10).

On August 6, 2021 Syntrix reported that A new study led by researchers at NYU Grossman School of Medicine and its Laura and Isaac Perlmutter Cancer Center revealed for the first time that activation of CXCR2 may be a general resistance-response to non-small cell lung cancer (NSCLC) treatments that inhibit the RAS/RAF/MEK/ERK signaling pathway, and may explain why many patients with lung cancer do not respond to such treatments (Press release, Syntrix, AUG 6, 2021, View Source [SID1234586025]).

Published in Cancer Discovery, findings from the study show that inhibition of CXCR2 signaling with SX-682 increased sensitivity of lung cancer to both investigational and FDA-approved therapies targeting the RAS/RAF/MEK/ERK signaling pathway.

Lung cancer is the most common cause of cancer-related death worldwide, with over 1.8 million lung cancer deaths annually and approximately 236,000 new cases in the U.S. NSCLC accounts for approximately 84% of new lung cancer diagnoses each year.

"These findings have major clinical implications with many existing and new NSCLC treatments inhibiting the RAS/RAF/MEK/ERK signaling pathway, including targeted therapies such as osimertinib to mutant EGFR, and sotorasib and adagrasib (MRTX849) to mutant RAS," said John A. Zebala, MD, PhD, co-author of the study and President at Syntrix Pharmaceuticals.

Using cell culture and mouse models, the NYU team demonstrated how inhibition of SHP2 (SHP2 is required for KRAS activation), KRAS, EGFR or MEK caused activation of CXCR2 signaling that drew granulocytic myeloid-derived suppressor cells (gMDSCs) into tumors. The infiltrating gMDSCs impaired the anti-tumor actions of T cells. The researchers found the same effects on CXCR2 signaling and gMDSC influx in tumors from patients treated with the KRAS G12C-specific inhibitor, adagrasib.

The researchers found that combining SX-682 with SHP2 inhibition in an extremely aggressive mouse tumor model significantly depleted gMDSC infiltration and generated CD8+ effector T cells with strong anti-tumor activity. Compared with SHP2 inhibition alone, the combination completely suppressed tumor growth after two weeks of treatment, the time point at which untreated tumor-bearing mice started to die. The combination also prolonged survival (median: 38 days) compared to SHP2 inhibition alone (median: 27 days) or SX682 alone (median: 21.5 days), more than doubling overall survival compared with untreated (median: 18 days) mice. The team found no toxicity after five weeks of combination treatment. The study concludes that the results support testing of RAS/ERK pathway inhibitors with SX-682 in NSCLC patients.

ABOUT SX-682: SX-682 is an oral allosteric small-molecule inhibitor of CXCR1 and CXCR2 (CXCR1/2) being investigated in several Phase 1/2 clinical trials. CXCR1/2 are a combined "master switch" of the tumor microenvironment. Clinical studies have shown an inverse correlation between blood CXCR1/2 ligands and immune-checkpoint blockade (ICB) response and survival. SX-682 has been validated in major solid tumor models, where it exhibits mono-agent activity, blocks metastasis, depletes MDSCs, activates infiltration and killing by immune effector cells, reverses chemo-resistance, and enhances ICB.
