IMM2510 is a novel, potentially best-in-class bispecific antibody consisting of an anti-PD-L1 antibody fused to a vascular endothelial growth factor (VEGF) receptor "trap" which binds VEGF. IMM2510 is differentiated from other PD(L)1xVEGF antibodies by its ability to bind multiple VEGF receptor ligands beyond VEGF-A, a smaller molecular weight allowing for potentially better tumor penetration, and enhanced antibody-dependent cellular cytotoxicity (ADCC) designed to improve tumor killing. IMM2510 has completed a dose-escalation clinical trial for advanced solid tumors and demonstrated multiple responses including patients with squamous non-small cell lung cancer (NSCLC) who previously failed PD-1 inhibitors.

IMM27M is a next-generation anti-CTLA-4 antibody with enhanced ADCC activity, which has been designed to promote intratumoral regulatory T cell depletion to enhance the efficacy and reduce the toxicity associated with first-generation anti-CTLA-4 antibodies. IMM27M has completed a dose-escalation clinical trial demonstrating anti-tumor activity in patients with advanced solid tumors and has entered combination studies with IMM2510 in China in July 2024.

Terms of License and Collaboration Agreement
Under the terms of the agreement, a wholly owned subsidiary of Instil will receive global development and commercialization rights for IMM2510 and IMM27M outside of Greater China, while ImmuneOnco will retain development and commercialization rights in Greater China including Taiwan, Macau, and Hong Kong. ImmuneOnco will receive an upfront payment and potential near-term payments of up to $50 million as well as potential additional development, regulatory, and commercial milestones exceeding $2 billion plus single digit to low double-digit percentage royalties on global ex-China sales.

On August 1, 2024 GSK plc (LSE/NYSE: GSK) reported the US Food and Drug Administration (FDA) has approved Jemperli (dostarlimab) in combination with carboplatin and paclitaxel (chemotherapy) followed by Jemperli as a single agent for the treatment of adult patients with primary advanced or recurrent endometrial cancer (Press release, GlaxoSmithKline, AUG 1, 2024, View Source [SID1234645260]). This approval broadens the previous indication for Jemperli plus chemotherapy to include patients with mismatch repair proficient (MMRp)/microsatellite stable (MSS) tumours who represent 70-75% of patients diagnosed with endometrial cancer and who have limited treatment options. The supplemental Biologics License Application (sBLA) supporting this expanded indication received Priority Review and was approved ahead of the Prescription Drug User Fee Act action date.

Hesham Abdullah, Senior Vice President, Global Head Oncology, R&D, GSK, said: "Jemperli plus chemotherapy is the first and only immuno-oncology regimen to show significant and meaningful improvement in overall survival for adult patients with primary advanced or recurrent endometrial cancer regardless of biomarker status. We are thrilled this option is now available for more patients in the US, including the 70-75% with MMRp/MSS tumours where treatment options have been limited."

Today’s expanded approval is based on results from dual primary endpoints of investigator-assessed progression-free survival (PFS) and overall survival (OS) from Part 1 of the RUBY phase III trial. RUBY Part 1 is the only clinical trial in this setting to show a statistically significant OS benefit in the full population of patients with primary advanced or recurrent endometrial cancer, demonstrating a 31% reduction in risk of death (HR: 0.69; 95% CI: 0.54–0.89) compared to chemotherapy alone.

At the 2.5-year landmark, 61% (95% CI: 54-67) of patients in the Jemperli plus chemotherapy group compared to 49% (95% CI: 43-55) in the chemotherapy group were alive. In addition, a 16.4-month improvement in median OS was observed with Jemperli plus chemotherapy versus chemotherapy alone (44.6 months [95% CI: 32.6–NR] vs. 28.2 months [95% CI: 22.1–35.6], respectively). The median duration of follow-up was more than three years.1 The safety and tolerability analysis from RUBY Part 1 showed a safety profile for Jemperli and carboplatin-paclitaxel that was generally consistent with the known safety profiles of the individual agents. The most common treatment-emergent adverse events (≥ 20%) in patients receiving Jemperli plus chemotherapy were nausea, alopecia, fatigue, peripheral neuropathy, anaemia, arthralgia, constipation, diarrhoea, myalgia, rash, hypomagnesemia, decreased appetite, peripheral sensory neuropathy and vomiting.

Matthew Powell, MD, Chief, Division of Gynecologic Oncology, Washington University School of Medicine, and US principal investigator of the RUBY trial said: "The initial approval of Jemperli plus chemotherapy was practice-changing for patients with dMMR/MSI-H primary advanced or recurrent endometrial cancer and today’s expanded approval will offer even more patients the opportunity for improved outcomes. This is the only immuno-oncology treatment regimen that has shown a statistically significant overall survival benefit for the full patient population, which is a meaningful step forward in treating this challenging cancer."

Adrienne Moore, Survivor, Founding Member and President of Endometrial Cancer Action Network for African-Americans (ECANA) said: "With this expanded approval for Jemperli plus chemotherapy, GSK is bringing a much-needed new treatment regimen to the endometrial cancer community that may help patients with primary advanced or recurrent endometrial cancer live longer, providing hope to patients and their families. Survivors and advocates should be excited by today’s news and especially delighted that this approval means that more patients in the US who are diagnosed with endometrial cancer will have a new treatment option."

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,2 with an estimated 1.6 million people living with active disease at any stage and 417,000 new cases reported each year worldwide.3 Incidence rates are expected to rise by approximately 40% between 2020 and 2040.4 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 mismatch repair deficient (dMMR)/microsatellite instability-high (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 opportunities for transformational outcomes.

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. This includes patients with MMRp/MSS and dMMR/MSI-H tumours. Jemperli is also approved 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. Additionally, Jemperli is 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.

"This significant designation by the EMA underscores the ongoing unmet need for new liver cancer therapies. Orphan designation further supports Elevar’s mission to bring a novel first-line systemic treatment option to patients in the EU diagnosed with hepatocellular carcinoma, a leading cause of cancer death in the EU and worldwide," commented Chris Galloway, M.D., senior vice president of clinical and medical affairs.

About EMA Orphan Designation[i]

To qualify for Orphan designation by EMA, a medicine must meet a number of criteria:

it must be intended for the treatment, prevention or diagnosis of a disease that is life-threatening or chronically debilitating;
the prevalence of the condition in the EU must not be more than 5 in 10,000 or it must be unlikely that marketing of the medicine would generate sufficient returns to justify the investment needed for its development;
no satisfactory method of diagnosis, prevention or treatment of the condition concerned can be authorized, or, if such a method exists, the medicine must be of significant benefit to those affected by the condition.
The European Union (EU) offers a range of incentives for medicines that have been granted an orphan designation by the European Commission, including access to a centralized authorization resulting in a single opinion and a single decision from the European Commission valid in all EU Member States. Additionally, authorized orphan medicines benefit from 10 years of protection from market competition with similar medicines with similar indications once they are approved.[ii]

About Hepatocellular Carcinoma

More than 800,000 people worldwide are diagnosed with liver cancer each year. Liver cancer is a leading cause of cancer accounting for more than 700,000 deaths annually.[iii] Hepatocellular Carcinoma (HCC) is the most common type of primary liver cancer. It most frequently develops in people with chronic underlying liver inflammation which may be from viral and non-viral causes. HCC typically has a poor prognosis with limited treatment options and continues to be a diagnosis with an ongoing urgent medical need.

About Rivoceranib Rivoceranib, a small-molecule tyrosine kinase inhibitor (TKI), is a highly potent inhibitor of vascular endothelial growth factor receptor (VEGFR), a primary pathway for tumor angiogenesis. VEGFR inhibition is a clinically validated target to limit tumor growth and disease progression. Rivoceranib is currently being studied as a monotherapy and in combination with chemotherapy and immunotherapy in various solid tumor indications. Ongoing clinical studies include uHCC (in combination with camrelizumab), gastric cancer (as a monotherapy and in combination with paclitaxel), adenoid cystic carcinoma (as a monotherapy) and colorectal cancer (in combination with Lonsurf). Rivoceranib was the first TKI approved in gastric cancer in China (November 2014). It is also approved in China in combination with camrelizumab as a first-line treatment for uHCC (January 2023). The drug has been studied in more than 6,000 patients worldwide and was well tolerated in clinical trials with a comparable safety profile to other TKIs and VEGF inhibitors. Orphan drug designations have been granted in gastric cancer (U.S., EU and South Korea), in adenoid cystic carcinoma (U.S.) and in uHCC (U.S.). Elevar Therapeutics, Inc. holds the global rights (excluding China) to rivoceranib and has partnered for its development and marketing with HLB-LS in South Korea. Rivoceranib, under the name apatinib, is also approved in China for advanced gastric cancer and in second-line advanced HCC by the Chinese -territory license-holder, Jiangsu Hengrui Pharmaceuticals Company Ltd., (Hengrui Pharma), under the brand name Aitan.

About Camrelizumab Camrelizumab (SHR-1210) is a humanized monoclonal antibody that binds to the programmed death-1 (PD-1) receptor. Blockade of the PD-1/PD-L1 signaling pathway is a therapeutic strategy showing success in a wide variety of solid and hematological cancers. Camrelizumab is developed by Hengrui Pharma and has been studied in more than 5,000 patients. Currently, 50 clinical trials are underway in a broad range of tumors (including liver cancer, lung cancer, gastric cancer, and breast cancer, etc.) and treatment settings. Camrelizumab, under the brand name AiRuiKa, is currently approved for eight indications in China, including monotherapy for the treatment of HCC (second-line), in combination with rivoceranib as a treatment for uHCC (first-line), relapsed/refractory classic Hodgkin’s lymphoma (third-line), esophageal squamous cell carcinoma (second-line) and nasopharyngeal carcinoma (third-line or further) and in combination with chemotherapy for the treatment of non-small cell lung cancer (non-squamous and squamous), esophageal squamous cell carcinoma and nasopharyngeal carcinoma in the first-line setting. The U.S. Food and Drug Administration granted Orphan Drug Designation to camrelizumab for advanced HCC in April 2021.

In October 2023, Elevar licensed camrelizumab, an anti-PD-1 antibody, for commercialization from Jiangsu Hengrui Pharmaceuticals Co., Ltd. (Hengrui Pharma) worldwide excluding Greater China and Korea.

Operational Highlights

TakeAim Lymphoma

In July 2024, emavusertib was granted Orphan Drug Designation (ODD) by the European Commission (EC) for the treatment of patients with primary central nervous system lymphoma (PCNSL). To qualify for ODD in the European Union, among several requirements, emavusertib must be intended for the treatment, prevention or diagnosis of a disease that is life-threatening or chronically debilitating and the prevalence of the condition must be fewer than 5 in 10,000 across the EU.

"We are extremely pleased that emavusertib has been granted ODD in the EU for the treatment of PCNSL. The designation is significant for the development of emavusertib in the EU and shows the high unmet need for this patient population," said Jonathan Zung, Chief Development Officer.

In addition to the EC ODD designation, Curis continues to progress the clinical development of emavusertib and expects to have initial data for 15-20 patients with R/R PCNSL by late 2024.

"We are pleased with our progress in the TakeAim Lymphoma study and look forward to providing updated data at the ASH (Free ASH Whitepaper) conference in December. As we continue the expansion of clinical sites in our PCNSL study, we have initiated discussions with health authorities to align on a registrational development path for emavusertib in PCNSL. We are excited to take this next step in advancing a novel treatment for patients with PCNSL," said James Dentzer, President and Chief Executive Officer.

TakeAim Leukemia

In May 2024, Curis released data for 25 new patients in the Relapsed/Refractory (R/R) FLT3 mutation (FLT3m) and U2AF1/SF3B1 Splicing Factor mutation (SFm) cohorts who had received fewer than 3 lines of prior therapy and were treated with emavusertib as monotherapy at the Recommended Phase 2 Dose (RP2D) of 300 mg BID. 12 R/R AML patients with FLT3m were treated with emavusertib. Preliminary data show 6 objective responses in 11 response-evaluable patients: 3 complete remission (CR), 1 CR with partial hematologic recovery (CRh) and 2 morphologic leukemia-free state (MLFS) with on-treatment duration range of 46-324 days. 4 patients were ongoing at the data-cutoff, including 1 CRh and 1 MLFS. 20 R/R AML patients with SFm were treated with emavusertib. Preliminary data show 4 of 18 response-evaluable patients in this population have achieved objective response (CR/CRh/MLFS). 8 of 20 patients were ongoing at the data-cutoff, including 1 MLFS. 2 patients were not response-evaluable.

Upcoming Presentations

On September 26, 2024, Curis will be hosting the 3rd Annual Symposium on IRAK-4 in cancer. The symposium will be hosted by Dr. Eric S. Winer and Dr. Grzegorz S. Nowakowski and will focus on IRAK-4 and the promise of IRAK-4 inhibition in both hematologic malignancies and solid tumors.

Upcoming Milestones

TakeAim Lymphoma – updated clinical data from the on-going combination study of emavusertib with ibrutinib in patients with R/R PCNSL in late 2024.
TakeAim Leukemia – updated clinical data from the on-going monotherapy study of emavusertib in patients with R/R AML with a FLT3 or SFm in late 2024.
Initial safety data from the frontline triplet combination study of emavusertib with azacitidine and venetoclax in patients with AML in late 2024.

"The granting of Fast Track Designation by the FDA highlights the significant unmet need for patients with relapsed or refractory PTCL," said Richard A. Miller, M.D., co-founder, president and chief executive officer of Corvus. "The current treatment options for these patients provide limited efficacy and are associated with significant toxicity, and there are no FDA fully approved agents. There continues to be strong interest in soquelitinib from investigators at sites with deep experience treating T cell lymphomas and we are on track to initiate patient enrollment in our registrational Phase 3 trial in PTCL in the third quarter 2024."

The Fast Track program is designed to facilitate the development and expedite the review of new drugs or biologics that are intended to: 1) treat serious or life-threatening conditions and 2) demonstrate the potential to address unmet medical needs. Fast Track designation can accelerate development and review of new drug and biological products by increasing the level of communication between FDA and drug developers and by enabling the FDA to review portions of a drug application on a rolling basis. In addition to Fast Track Designation, soquelitinib has also been granted FDA Orphan Drug Designation for the treatment of T cell lymphoma, which provides benefits to drug developers, including assistance in the drug development process, tax credits for clinical costs, exemptions from certain FDA fees and seven years of post-approval marketing exclusivity.
