IDH mutations occur in approximately 80% of low-grade gliomas, promoting tumorigenesis through increased levels of the oncometabolite D-2-hydroxyglutarate (2-HG). Data from the ongoing perioperative study found that treatment with vorasidenib 50 mg and TIBSOVO 500 mg resulted in mean percent reduction in 2-HG (95% CI) of 92.6% (76.1, 97.6) and 91.1% (72.0, 97.0), respectively, relative to untreated samples in patients with low-grade glioma.

"The updated data demonstrate that robust 2-HG suppression by vorasidenib and TIBSOVO resulted in positive changes in both the tumor cells and the tumor immune microenvironment," said Ingo Mellinghoff, M.D., Memorial Sloan Kettering Cancer Center, an investigator for the study. "These findings underscore that the mutant IDH enzyme plays an active role in the growth of low-grade gliomas and that IDH inhibition may play a significant role in the future treatment of these tumors."

The study data demonstrated that short-term treatment with vorasidenib and TIBSOVO reduced tumor cell proliferation, altered the epigenetic state, and promoted the expression of genes associated with cellular differentiation. Additionally, the data showed that treatment with vorasidenib and TIBSOVO activated interferon signaling and increased T-cell infiltration.

"These early results further support the role of IDH inhibition in treating patients with hard-to-treat cancers, including IDH mutant low-grade glioma," said Susan Pandya, M.D., Vice President, Clinical Development, Head of Cancer Metabolism Global Development, Servier Pharmaceuticals. "These data build on evidence that vorasidenib demonstrates anti-tumor activity through 2-HG suppression and we look forward to confirming the clinical benefit of vorasidenib in patients with IDH mutant low-grade gliomas in the global Phase 3 INDIGO study."

TIBSOVO (ivosidenib tablets) is currently approved in the U.S. as monotherapy for the treatment of adults with IDH1-mutant relapsed or refractory acute myeloid leukemia (AML) and for adults with newly diagnosed IDH1-mutant AML who are ≥75 years old or who have comorbidities that preclude the use of intensive induction chemotherapy.

Vorasidenib, an investigational, oral, brain-penetrant dual inhibitor of mutant IDH1 and IDH2 enzymes, is currently being evaluated in the registration-enabling Phase 3 INDIGO study as a potential treatment for patients with residual or recurrent grade 2 glioma.

Perioperative Study of Vorasidenib and TIBSOVO

Vorasidenib and TIBSOVO are being evaluated as a single agent in an ongoing perioperative study in IDH1-mutant Grade 2/3 glioma. The primary endpoint is 2-hydroxyglutarate (2-HG) concentration in tumors resected following presurgical treatment with vorasidenib and TIBSOVO compared with untreated control tumors. Patients were randomized to 500 mg TIBSOVO once daily, 50 mg vorasidenib once daily or the control arm in cohort 1; and 250 mg TIBSOVO twice daily or 10 mg vorasidenib once daily in cohort 2. Patients were treated for four weeks prior to surgery and had the option to continue postoperative treatment until disease progression.

About Glioma

Glioma presents in varying degrees of tumor aggressiveness, ranging from slower growing (low-grade glioma) to rapidly progressing (high-grade glioma-Glioblastoma Multiforme). Tumor enhancement is an imaging characteristic assessed by magnetic resonance imaging (MRI), and enhancing tumors are more likely to be high-grade.

Common symptoms of glioma include seizures, memory disturbance, sensory impairment and neurologic deficits. The long-term prognosis is poor, and regardless of treatment, the majority of patients with low-grade gliomas will have recurrent disease that will progress over time. Approximately 11,000 low-grade glioma patients are diagnosed annually in the U.S. and EU and somatic mutations in IDH1 and IDH2 occur in approximately 80% of low-grade gliomas.

On June 6, 2021 Innovent Biologics, Inc. ("Innovent", HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high-quality medicines for the treatment of cancer, metabolic, autoimmune and other major diseases, reported that the results of the Phase 1 study in Chinese patients with advanced solid tumors were released today at the American Society for Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting 2021 (Press release, Innovent Biologics, JUN 6, 2021, View Source [SID1234583619]).

This is a Phase 1 study to evaluate the pharmacokinetic (PK), pharmacodynamic (PD) and safety of pemigatinib in Chinese patients (pts) with advanced malignancy. Moreover, potential efficacy of pemigatinib was explored in a broad spectrum of fibroblast growth factor receptor (FGFR) alteration in variety of cancer types. 12 patients with 5 different cancer types (colorectal cancer, gastric cancer, cholangiocarcinoma, esophageal carcinoma and breast cancer) and FGF/FGFR1-3 alterations were enrolled. All the subjects were failed to prior standard therapy. As of Jan 31, 2021, all patients received at least once treatment, the safety was controllable with the most common treatment related adverse events (TRAE) of hyperphosphatemia, decreased appetite and diarrhea. Two patients reported ≥ grade 3 TRAEs, which were hyponatremia and proteinuria. There were no TEAEs leading to death or treatment discontinuation. Among 11 efficacy evaluable patients, 2 of them had partial responses (PR) as evaluated by investigators with 1 cholagiocarcinoma harboring FGFR2 point mutation (p.F276C) and the other esophageal carcinoma carrying FGFR1 mutation (p.A354V). 3 patients had a best overall response of stable disease (SD). The objective response rate (ORR) was 16.7% (95%CI: 2–48%) and disease control rate was 41.7% (95%CI: 15–72%).

Professor Yi Ba from Tianjin Medical University Cancer Institute and Hospital said," Pemigatinib had an acceptable and manageable toxicity in Chinese patients with advanced malignancy. A significant implication of the data is that it extended the population that potentially benefit from pemigatinib other than FGFR2 fusion/rearrangement."

"Several FGFR inhibitors are being in clinical stage" said Dr. Hui Zhou, Senior Vice President of Clinical Development, Innovent Biologics. "Innovent has multiple clinical trials of pemigatinib for the treatment of cholangiocarcinoma and other types of tumors. Currently we are preparing the New Drug Application (NDA) of pemigatinib in China. We presented the data at the ASCO (Free ASCO Whitepaper) Annual Meeting, which highlighted our capability of small molecules. In the future, we will conduct in-depth clinical development of pemigatnib to explore its treatment in other indications. We are looking forward to providing innovative therapies for more cancer patients in the future."

About Pemazyre (pemigatinib)

In April 2020, the U.S. Food and Drug Administration (FDA) approved Incyte’s Pemazyre (pemigatinib), a selective, oral inhibitor of FGFR isoforms 1, 2 and 3, for the treatment of adults with previously treated, unresectable locally advanced or metastatic cholangiocarcinoma with a fibroblast growth factor receptor 2 (FGFR2) fusion or rearrangement as detected by an FDA-approved test. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

In Japan, Pemazyre is approved for the treatment of patients with unresectable biliary tract cancer with a FGFR2 fusion gene, worsening after cancer chemotherapy. In Europe, Pemazyre is approved for the treatment of adults with locally advanced or metastatic cholangiocarcinoma with a FGFR2 fusion or rearrangement that have progressed after at least one prior line of systemic therapy. Pemazyre is marketed by Incyte in the United States, Europe and Japan.

In December 2018, Innovent and Incyte entered into a strategic collaboration for three clinical-stage product candidates discovered and developed by Incyte, including pemigatinib (FGFR1/2/3 inhibitor). Under the terms of the agreement, Innovent has received the rights to develop and commercialize the three assets in Mainland China, Hong Kong, Macau and Taiwan.

Pemazyre is a trademark of Incyte Corporation.

This is a Phase 1b dose escalation and dose expansion study to evaluate the tolerability, safety and preliminary efficacy of sintilimab plus fruquintinib, and to determine the recommended phase 2 dose (RP2D). 44 CRC patients that had failed at least 2 previous lines of therapy containing fluoropyrimidine, oxaliplatin or irinotecan were enrolled. They received either 5mg-intermittent or 3mg-continous dosage (n=22, each). The objective response rate (ORR) was 22.7% (10/44, 95% CI: 11.5-37.8%) with 27.3% (6/22, 95% CI: 10.7-50.2%) in the 5mg-intermittent group and 18.2% (4/22, 95% CI: 5.2-40.3%) in the 3mg-continuous group. With a median follow-up time of 11.3 (range: 9.8-11.7) months, the Kaplan-Meier estimated median progression free survival (PFS) was 5.6 (95% CI:4.3-7.5) months among all 44 patients, with 6.9 (95% CI:5.4-8.3) months for the 5mg-intermittent group and 4.2 (95% CI:2.9-9.5) months for the 3mg-continuous group. The safety for this combination therapy was controllable.

Dr. Hui Zhou, Senior Vice President of Clinical Development, Innovent Biologics, said, "The preliminary results were very encouraging, which have given us a very promising efficacy signal that TYVYT (sintilimab injection) in combination with ELUNATE (fruquintinib) could be used as a third-line treatment for advanced CRC with microsatellite stability. These results would warrant further investigation in a larger population. This study also underscores our commitment to provide innovative treatment options to patients with cancer."

Dr. Weiguo Su, Chief Scientific Officer of HUTCHMED, said, "Fruquintinib’s clean profile led us to evaluate this sintilimab combination in many different tumor types, with this favorable safety profile further highlighted by the combination’s RP2Ds similarity to their monotherapy RP2D. This CRC data at RP2D is promising, showing median PFS at nearly double what was demonstrated under monotherapy. We are exploring next steps in bringing this novel therapy to cancer patients."

About Colorectal Cancer

Colorectal cancer is one of the most common malignancies in the world with relatively high morbidity and mortality. With the improvement of living conditions, the incidence of CRC in China has been increasing in recent years. Surgery is the major treatment for early stage CRC, but a large proportion of patients who have received surgery would develop relapse or distant metastasis, and die from disease progression. More than 95% of advanced CRCs are microsatellite stable, with very limited efficacy of immunotherapy and large unmet clinical needs.

About TYVYT (Sintilimab Injection)

TYVYT (sintilimab injection) is an innovative PD-1 inhibitor with global quality standards jointly developed by Innovent and Lilly. Sintilimab is a type of immunoglobulin G4 monoclonal antibody, which binds to PD-1 molecules on the surface of T-cells, blocks the PD-1 / PD-Ligand 1 (PD-L1) pathway, and reactivates T-cells to kill cancer cells. Innovent is currently conducting more than 20 clinical studies of sintilimab to evaluate its safety and efficacy in a wide variety of cancer indications, including more than 10 registrational or pivotal clinical trials.

In China, TYVYT (sintilimab Injection) has been approved for two indications, including:

The treatment of relapsed or refractory classic Hodgkin’s lymphoma after two lines or later of systemic chemotherapy
In combination with pemetrexed and platinum chemotherapy, for the first-line treatment of nonsquamous non-small cell lung cancer
In combination with gemcitabine and platinum chemotherapy, for the first-line treatment of squamous non-small cell lung cancer
Additionally, Innovent currently has regulatory submissions under review in China for TYVYT (sintilimab Injection):

In combination with BYVASDA (bevacizumab injection) for the first-line treatment of hepatocellular carcinoma
The second-line treatment of squamous non-small cell lung cancer
In May 2021, the U.S. FDA accepted for review the Biologics License Application (BLA) for sintilimab in combination with pemetrexed and platinum chemotherapy for the first-line treatment of nonsquamous non-small cell lung cancer.

TYVYT (sintilimab Injection) was included in China’s National Reimbursement Drug List (NRDL) in 2019 as the first PD-1 inhibitor and the only PD-1 included in the list in that year..

About ELUNATE (fruquintinib)

Fruquintinib is a highly selective and potent oral inhibitor of VEGFRs –1, –2 and –3. VEGFR inhibitors play a pivotal role in blocking tumor angiogenesis. Fruquintinib was designed to improve kinase selectivity to minimize off-target toxicities, improve tolerability and provide more consistent target coverage. The generally good tolerability in patients to date, along with fruquintinib’s low potential for drug-drug interaction based on preclinical assessment, suggests that it may also be highly suitable for combinations with other anti-cancer therapies.

Fruquintinib was approved for marketing by the NMPA in September 2018 and is marketed under the brand name ELUNATE in China. ELUNATE is for the treatment of patients with metastatic CRC that have been previously treated with fluoropyrimidine, oxaliplatin and irinotecan, including those who have previously received anti-VEGF therapy and/or anti-EGFR therapy (RAS wild type).

HUTCHMED retains all rights to fruquintinib outside of China. In China, HUTCHMED is partnered with Eli Lilly and Company and is responsible for development and execution of all on-the-ground medical detailing, promotion and local and regional marketing.

On June 6, 2021 Innovent Biologics, Inc. ("Innovent", HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high-quality medicines for the treatment of cancer, metabolic, autoimmune and other major diseases, together with AnHeart Therapeutics Co., Ltd ("AnHeart"), a clinical stage oncology company focused on underserved patients in global markets, reported a presentation of a scientific poster entitled "Preliminary results from TRUST: A phase II clinical study to investigate Taletrectinib in treating patients with ROS1 fusion positive non-small cell lung cancer (NSCLC)" which summarizes initial data from its ongoing trial of taletrectinib (NCT04395677) at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) 2021 Annual Meeting (Press release, Innovent Biologics, JUN 6, 2021, View Source [SID1234583621]).

As of the data cut-off date of April 8, 2021, there were 15 crizotinib treatment-naïve patients and 5 crizotinib pre-treated patients, who had been confirmed to be ROS1 fusion positive and assessed at least twice by investigators. The results were as follows:

In the crizotinib treatment-naïve patients (n=15), the overall response rate (ORR) was 93% (14/15) and the disease control rate (DCR) was 93% (14/15);
In the crizotinib pre-treated patients (n=5), the ORR was 60% (3/5); and the DCR was 100% (5/5). ROS1 G2032R resistant mutations were identified in three of the five patients and all three patients experienced tumor regressions; and
Taletrectinib has shown a manageable safety profile characterized primarily by gastrointestinal adverse events, with reversible increases of aspartate aminotransferase (AST) and alanine aminotransferase (ALT).
"These safety and efficacy data for taletrectinib are very promising for ROS1 fusion positive lung cancer patients," said Dr. Caicun Zhou, director of the Department of Oncology, Shanghai Pulmonary Hospital. "Responses appear particularly impressive in crizotinib treatment-naïve patients, and while the number of crizotinib pre-treated patients is limited, thus far all five patients continue to benefit from the drug."

"We are glad to see the study result of Taletrectinib can be presented at ASCO (Free ASCO Whitepaper) meeting, the most authoritative clinical oncology conference", said Dr. Hui Zhou, Senior Vice President of Clinical Development, Innovent Biologics, "In China, ROS1 positive fusion patients have limited treatment choices at present. More new drugs are needed to develop for clinical application. Taletrectinib has shown good efficacy and safety results, which offers hope to patients with ROS1 fusion positive non-small cell lung cancer."

"Our team is highly focused on completing patient enrollment for this phase II TRUST trial in Q3 2021," said Bing Yan, MD, co-founder and chief medical officer of AnHeart. "These data from the TRUST trial have built a solid foundation for our upcoming global trials of taletrectinib and will support us in seeking regulatory approvals of talectrectinib in China and globally. We sincerely thank the patients, their families and investigators in the TRUST trial and look forward to bringing taletrectinib to all ROS1 fusion positive patients in the near future upon approval."

About Taletrectinib

Taletrectinib is an investigational next-generation tyrosine kinase inhibitor (TKI) designed to effectively target ROS1 and NTRK fusion mutations with potential to treat TKI-naïve or pre-treated patients. ROS1 rearrangement is estimated to be an oncogenic driver in approximately 2 to 3 percent of patients with advanced NSCLC, and NTRK rearrangement is estimated to be an oncogenic driver in approximately 0.5 percent of patients with other advanced solid tumors. More information about the ongoing TRUST (Taletrectinib ROS1 LUng STudy) trial and the basket trial in NTRK fusion positive solid tumors of taletrectinib may be found by searching clinical trial identifiers NCT04395677 and NCT04617054, respectively at View Source

On 1 June 2021, Innovent and Anheart announced an exclusive license agreement for the co-development and commercialization of AnHeart’s lead drug candidate, taletrectinib – a next-generation tyrosine kinase inhibitor (TKI) designed to effectively target ROS1 and NTRK – in Greater China, including mainland China, Hong Kong, Macau and Taiwan.
