OVATION 2 is evaluating the dosing, safety, efficacy and biological activity of intraperitoneal administration of IMNN-001 in combination with neoadjuvant chemotherapy (NACT) in patients newly diagnosed with advanced epithelial ovarian, fallopian tube or primary peritoneal cancer. Treatment in the neoadjuvant period is designed to shrink the tumors as much as possible for optimal surgical removal after three cycles of chemotherapy. Following NACT, patients undergo interval debulking surgery, followed by three additional cycles of adjuvant chemotherapy to treat any residual tumor. Patients were randomized 1:1 and evaluated for safety and efficacy to compare NACT plus IMNN-001 versus standard-of-care NACT. Patients randomized to the IMNN-001 treatment arm received up to 17 doses of 100 mg/m2, in addition to NACT. Full enrollment of 110 patients was reached in September 2022.

The OVATION 2 Study is meant to inform the design of the intended Phase 3 trial and was not powered for statistical significance. Per the Statistical Analysis Plan (SAP), the primary efficacy analysis will be based on the Intent to Treat (ITT) population. The primary efficacy endpoint is PFS, with secondary endpoints including OS, Objective Response Rate, Chemotherapy Response Score and Surgical Response.

Stacy Lindborg, Ph.D., president and chief executive officer of IMUNON, said, "Reaching data lock for the OVATION 2 Study is a significant achievement for our team and a step forward in our mission to bring an innovative treatment to patients battling ovarian cancer. With the last patient enrolled in September 2022, the analyses generated using the ITT population, an industry gold standard, will now have sufficient data maturity to analyze both PFS and OS endpoints with a good level of confidence. We are hopeful that IMNN-001 will offer improved outcomes and a much-needed alternative to those affected by this deadly disease."

Sebastien Hazard, M.D., Ph.D., chief medical officer of IMUNON, added, "Given the maturity of our data, OS will be important in the readout of the trial and in planning the Phase 3 trial. As the definitive endpoint, OS has been observed across all tumor types as most reflective of the long-term benefit of immunotherapies. We look forward to the trial readout and sharing learnings from the trial with the patient and medical community."

About IMNN-001 Immunotherapy

Designed using IMUNON’s proprietary TheraPlas platform technology, IMNN-001 is an interleukin-12 (IL-12) DNA plasmid vector encased in a nanoparticle delivery system that enables cell transfection followed by persistent, local secretion of the IL-12 protein. IL-12 is one of the most active cytokines for the induction of potent anticancer immunity acting through the induction of T-lymphocyte and natural killer cell proliferation. IMUNON previously reported positive safety and encouraging Phase 1 results with IMNN-001 administered as monotherapy or as combination therapy in patients with advanced peritoneally metastasized primary or recurrent ovarian cancer, and completed a Phase 1b dose-escalation trial (the OVATION 1 Study) of IMNN-001 in combination with carboplatin and paclitaxel in patients with newly diagnosed ovarian cancer.

About Epithelial Ovarian Cancer

Epithelial ovarian cancer is the fifth deadliest malignancy among women in the United States. There are approximately 22,000 new cases of ovarian cancer every year and approximately 70% are diagnosed in advanced Stage III/IV. Epithelial ovarian cancer is characterized by dissemination of tumor in the peritoneal cavity with a high risk of recurrence (75% in Stage III/IV) after surgery and chemotherapy. Since the five-year survival rates of patients with Stage III/IV disease at diagnosis are poor (41% and 20%, respectively), there remains a need for a therapy that not only reduces the recurrence rate, but also improves overall survival. The peritoneal cavity of advanced ovarian cancer patients contains the primary tumor environment and is an attractive target for a regional approach to immune modulation.

Jemperli (dostarlimab) plus chemotherapy application accepted for review by the European Medicines Agency to expand use to all patients with primary advanced or recurrent endometrial cancer

On June 24, 2024 GSK plc (LSE/NYSE: GSK) reported the European Medicines Agency (EMA) has accepted its application to expand the use of Jemperli (dostarlimab) in combination with standard-of-care chemotherapy (carboplatin and paclitaxel) to all adult patients with primary advanced or recurrent endometrial cancer (Press release, GlaxoSmithKline, JUN 24, 2024, View Source [SID1234644500]). The EMA’s Committee for Medicinal Products for Human Use will begin the formal review process to make a recommendation to the European Commission, with approval expected in H1 2025.

Currently, in the EU, Jemperli in combination with carboplatin and paclitaxel is approved for the treatment of adult patients who are candidates for systemic therapy with primary advanced or recurrent endometrial cancer that is mismatch repair deficient (dMMR) or microsatellite instability-high (MSI-H). If this new application is approved, dostarlimab would be expanded to all patients with primary advanced or recurrent endometrial cancer, regardless of their biomarker type, including those with mismatch repair proficient (MMRp)/microsatellite stable (MSS) tumours where currently there are no approved frontline immuno-therapy-based treatments in the EU.

The application is based on results from Part 1 of the RUBY phase III trial. The trial met its primary endpoints of investigator-assessed progression-free survival (PFS) and overall survival (OS), demonstrating a statistically significant and clinically meaningful benefit in the overall population of patients treated with dostarlimab plus carboplatin-paclitaxel versus chemotherapy alone. RUBY Part 1 is the only clinical trial to show a statistically significant overall survival benefit in this patient population. The safety and tolerability analyses from RUBY showed a safety profile for dostarlimab plus carboplatin-paclitaxel that was generally consistent with the known safety profiles of the individual agents.

OS data were presented at the Society of Gynecologic Oncology Annual Meeting on Women’s Cancer on 16 March 2024, and were published in Annals of Oncology on 9 June 2024.

About endometrial cancer
Endometrial cancer is found in the inner lining of the uterus, known as the endometrium. Endometrial cancer is the most common gynaecologic cancer in developed countries, with approximately 417,000 new cases reported each year worldwide1, and incidence rates are expected to rise by almost 40% between 2020 and 2040.2,3 In Europe, approximately 121,000 people are estimated to be diagnosed with primary advanced or recurrent endometrial cancer each year.4 Approximately 15-20% of patients with endometrial cancer will be diagnosed with advanced disease at the time of diagnosis.5 Among patients with primary advanced or recurrent endometrial cancer, approximately 70-75% have MMRp/MSS tumours.6

About RUBY
RUBY is a two-part global, randomised, double-blind, multicentre phase III trial of patients with primary advanced or recurrent endometrial cancer. Part 1 is evaluating dostarlimab plus carboplatin-paclitaxel followed by dostarlimab versus carboplatin-paclitaxel plus placebo followed by placebo. Part 2 is evaluating dostarlimab plus carboplatin-paclitaxel followed by dostarlimab plus niraparib versus placebo plus carboplatin-paclitaxel followed by placebo.

In Part 1, the dual-primary endpoints are investigator-assessed PFS based on the Response Evaluation Criteria in Solid Tumours v1.1 and OS. The statistical analysis plan included pre-specified analyses of PFS in the dMMR/MSI-H and overall populations and OS in the overall population. Pre-specified exploratory analyses of PFS and OS in the MMRp/MSS population and OS in the dMMR/MSI-H populations were also performed. RUBY Part 1 included a broad population, including histologies often excluded from clinical trials and had approximately 10% of patients with carcinosarcoma and 20% with serous carcinoma.

In Part 2, the primary endpoint is investigator-assessed PFS in the overall population, followed by PFS in the MMRp/MSS population, and OS in the overall population is a key secondary endpoint. Additional secondary endpoints in Part 1 and Part 2 include PFS per blinded independent central review, PFS2, overall response rate, duration of response, disease control rate, patient-reported outcomes, and safety and tolerability.

RUBY is part of an international collaboration between the European Network of Gynaecological Oncological Trial groups (ENGOT), a research network of the European Society of Gynaecological Oncology (ESGO) that consists of 22 trial groups from 31 European countries that perform cooperative clinical trials, and the GOG Foundation, a non-profit organisation dedicated to transforming the standard of care in gynaecologic oncology.

About Jemperli (dostarlimab)
Jemperli, a programmed death receptor-1 (PD-1)-blocking antibody, is the backbone of GSK’s ongoing immuno-oncology-based research and development programme. A robust clinical trial programme includes studies of Jemperli alone and in combination with other therapies in gynaecologic, colorectal and lung cancers, as well as where there are other opportunities for transformational outcomes. It was the first immuno-oncology treatment approved, in combination with chemotherapy, in the frontline setting for primary advanced or recurrent dMMR/MSI-H endometrial cancer.

In the US, Jemperli is indicated in combination with carboplatin and paclitaxel, followed by Jemperli as a single agent for the treatment of adult patients with primary advanced or recurrent endometrial cancer that is dMMR, as determined by a US FDA-approved test, or MSI-H, and as a single agent for adult patients with dMMR recurrent or advanced endometrial cancer, as determined by a US FDA-approved test, that has progressed on or following a prior platinum-containing regimen in any setting and are not candidates for curative surgery or radiation. The sBLA supporting this indication in combination with carboplatin and paclitaxel for dMMR/MSI-H primary advanced or recurrent endometrial cancer received Breakthrough Therapy designation and Priority Review from the US FDA. Jemperli is also indicated in the US for patients with dMMR recurrent or advanced solid tumours, as determined by a US FDA-approved test, that have progressed on or following prior treatment and who have no satisfactory alternative treatment options. The latter indication is approved in the US under accelerated approval based on tumour response rate and durability of response. Continued approval for this indication in solid tumours may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

Jemperli was discovered by AnaptysBio, Inc. and licensed to TESARO, Inc., under a collaboration and exclusive license agreement signed in March 2014. Under this agreement, GSK is responsible for the ongoing research, development, commercialisation, and manufacturing of Jemperli, and cobolimab (GSK4069889), a TIM-3 antagonist.

Important Information for Jemperli in the EU

GSK’s Omjjara (momelotinib) approved in Japan for treatment of myelofibrosis

On June 24, 2024 GSK plc (LSE/NYSE: GSK) reported that Japan’s Ministry of Health, Labour and Welfare (MHLW) has approved Omjjara (momelotinib) for the treatment of myelofibrosis (Press release, GlaxoSmithKline, JUN 24, 2024, View Source [SID1234644499]). Omjjara is a once-a-day, oral JAK1/JAK2 and activin A receptor type 1 (ACVR1) inhibitor. The approval is based on data from the pivotal phase III MOMENTUM and SIMPLIFY-1 trials.

This is the fourth major regulatory approval for GSK’s momelotinib in the treatment of myelofibrosis, following approval under the brand name Ojjaara from the US Food and Drug Administration and authorisations under the brand name Omjjara from the European Commission and the Medicines and Healthcare products Regulatory Agency in the UK.

Nina Mojas, Senior Vice President, Oncology Global Product Strategy, GSK, said: "Myelofibrosis has a heavy disease burden, with symptomatic patients experiencing spleen enlargement, fatigue, night sweats and bone pain, along with anaemia which can lead to treatment discontinuation and dependence on regular blood transfusions. With the approval of Omjjara, myelofibrosis patients in Japan will have a new treatment option for this complex blood cancer."

Myelofibrosis is a blood cancer that affects approximately 1 in 500,000 people worldwide, with up to 5,000 patients impacted in Japan.4,5,6 In Japan, about 70% of patients diagnosed with primary myelofibrosis, and about half of those patients diagnosed with secondary myelofibrosis, have moderate to severe anaemia at the time of diagnosis.1,2,3 Nearly all patients are estimated to develop anaemia over the course of the disease.7,8,9,10 Myelofibrosis patients with anaemia require additional supportive care, including transfusions, and more than 30% will discontinue treatment with established therapies due to anaemia.11 Patients who are anaemic and transfusion dependent have a poor prognosis and shortened survival.12,13,14,15,16,17,18,19,20

The approval is based on data from the MOMENTUM and SIMPLIFY-1 pivotal phase III trials. MOMENTUM was designed to evaluate the safety and efficacy of momelotinib versus danazol for the treatment and reduction of key manifestations of myelofibrosis in an anaemic, symptomatic, JAK inhibitor-experienced population. SIMPLIFY-1 was designed to evaluate the efficacy and safety of momelotinib versus ruxolitinib in myelofibrosis patients who had not received a prior JAK inhibitor therapy.

About Omjjara (momelotinib)
Momelotinib has a differentiated mechanism of action, with inhibitory ability along three key signalling pathways: Janus kinase (JAK) 1, JAK2, and activin A receptor, type I (ACVR1).1,21,22,23 Inhibition of JAK1 and JAK2 may improve constitutional symptoms and splenomegaly.1,21,23 Additionally, inhibition of ACVR1 leads to a decrease in circulating hepcidin levels, potentially contributing to anaemia-related benefit.1,21,22,23

In September 2023, the US Food and Drug Administration licensed24 momelotinib under the brand name Ojjaara for the treatment of intermediate or high-risk myelofibrosis, including primary myelofibrosis or secondary myelofibrosis (post-polycythaemia vera and post-essential thrombocythemia), in adults with anaemia.

In January 2024, the European Commission granted marketing authorisation25 for Omjjara for disease-related splenomegaly (enlarged spleen) or symptoms in adult patients with moderate to severe anaemia who have primary myelofibrosis, post polycythaemia vera myelofibrosis or post essential thrombocythemia myelofibrosis and who are Janus kinase (JAK) inhibitor naïve or have been treated with ruxolitinib. Omjjara was also approved26 by the Medicines and Healthcare products Regulatory Agency (MHRA) in the United Kingdom to treat the symptoms experienced by adult myelofibrosis patients who have moderate or severe anaemia.

Please refer to the updated Product Information (PI) for precautions concerning indication and important dosage, administration, and safety information in Japan which will shortly be updated at this link: Japan Pharmaceuticals and Medical Devices Agency.27

About myelofibrosis
Myelofibrosis is a rare blood cancer that disrupts the body’s normal production of blood cells because of dysregulated JAK-signal transducer and activator of transcription protein signalling. The clinical hallmarks of myelofibrosis are splenomegaly (enlarged spleen), severely low blood counts, including anaemia and thrombocytopenia, and debilitating constitutional symptoms, such as fatigue, night sweats and bone pain, attributable to ineffective haematopoiesis and excessive production of proinflammatory cytokines.28,29

About the pivotal clinical trials
MOMENTUM was a phase III, global, multicentre, randomised, double-blind study investigating momelotinib versus danazol in patients (n=195) with myelofibrosis who were symptomatic and anaemic and had been previously treated with a licensed JAK inhibitor. The trial was designed to evaluate the safety and efficacy of momelotinib for treating and reducing key hallmarks of the disease: symptoms, blood transfusions (due to anaemia) and splenomegaly. The MOMENTUM trial met all its primary and key secondary endpoints, demonstrating statistically significant response with respect to constitutional symptoms, splenic reduction and transfusion independence in patients treated with momelotinib versus danazol (Total Symptom Score reduction of 50% or greater: 25% momelotinib, 9% danazol, p=0.0095; reduction of spleen volume by 35% or greater: momelotinib 22%, danazol 3%, p=0.0011; no transfusions and all haemoglobin values ≥8 g/dL in the 12 weeks prior to week 24: momelotinib 30%, danazol 20%).30 The most common non-haematological treatment-emergent adverse events in momelotinib-treated patients over the entire study period as of the data cutoff were diarrhoea (45 [26%] of 171) and asthenia (28 [16%]); the most common grades 3 and 4 treatment-emergent adverse events were thrombocytopenia (33 [19%]) and anaemia (19 [11%]).31 Results from the 24-week randomised treatment period were presented at the 2022 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting and subsequently published in The Lancet,32,33 with 48-week data presented at the 64th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition in December 2022 and subsequently published in The Lancet Hematology.31,34

SIMPLIFY-1 was a multicentre randomised, double-blind, phase III study that compared the safety and efficacy of momelotinib to ruxolitinib in patients with myelofibrosis who had not received prior treatment with a JAK inhibitor (momelotinib: n=215 and ruxolitinib: n=217). SIMPLIFY-1 met its primary endpoint, demonstrating non-inferiority of momelotinib to ruxolitinib in spleen volume response (reduction by 35% or greater) with a difference of 9% (95% CI 2%-16%), and substantial improvements in transfusion independence rates (66.5% for momelotinib compared to 49.3% for ruxolitinib), a difference of 18% (95% CI 9%-26%).35,36 The most common grade 3 or higher haematologic abnormalities in either group were thrombocytopenia and anaemia. Grade 3 or higher infections occurred in 7% of patients who received momelotinib and 3% of patients who received ruxolitinib.
