DUBLIN--( BUSINESS WIRE )--The "Global MCL1 Inhibitor Drug Clinical Trials & Commercialization Opportunity Insights 2023" report has been added to ResearchAndMarkets.com's offering. A compelling case has been made for the use of MCL-1 inhibitors in the treatment of cancer by the positive preclinical trial results of numerous other investigational candidates besides S63845. MCL-1 also has the potential to be used as a therapeutic target for a variety of malignancies, as evidenced by the outcomes of the expansion of these candidates to solid tumors. Research and development of MCL-1 inhibitors is still an emerging field, however, prominent pharmaceutical companies like Amgen, Novartis, and AstraZeneca have also invested in the development of these candidates, which vouches for the future potential of MCL-1 inhibitors and the unanticipated market growth in the coming years. There still remain certain drawbacks associated with MCL-1 inhibitors that need to be addressed to realize the prospective growth potential of the MCL-1 inhibitors market. MCL-1 has been identified as a central protein in the pathogenesis of several cancers, majorly hematopoietic malignancies. It is a dynamic and unique protein, which is involved in a variety of cellular functions, including cell cycle progression, metabolism, and differentiation among others. However, its role as a pro-survival member of the BCL-2 that prevents apoptosis is what has brought it into the limelight as a promising therapeutic target for cancer. In addition, overexpression of MCL-1 also promoted drug resistance of both solid tumors and hematological malignancies to various chemotherapeutic agents through different signaling mechanisms. Therefore, due to its key role in promoting cell survival and the resistance to treatment, MCL-1 has emerged as a promising therapeutic target, and researchers are now working to find strategies to inhibit MCL-1. Compared to other proteins, targeted inhibition of the MCL-1 has more advantages. The protein is overexpressed in a number of cancers including breast and lung cancers, two cancers having the highest incidence and mortality rates. MCL-1 can prevent the process of apoptosis in cancer cells and promote survival, leading to an increase in tumor mass. In preclinical trials, inhibition of the MCL-1 was shown to induce cell death. Additionally, it also increased the efficacy of other anticancer drugs administered in combination with the MCL-1 inhibitor. Further, MCL-1 is also indicated in the development of resistance to current treatments. Especially in blood cancers, resistance to treatment is a common event occurring in cancer patients and is something that has been challenging the treatment outcomes and survival of patients. Overexpression of MCL-1 plays a role in this as its upregulation can counteract the effects of drugs that induce apoptosis otherwise. Targeting the MCL-1 can overcome this resistance and enhance the effectiveness of chemotherapies used in treating hematopoietic cancers. Adding on to this, the combination of MCL-1 inhibitors with other targeted therapies and anticancer drugs can have a synergic effect on cancer cells, leading to enhanced cell death and improved treatment outcomes. Research has also found that while normal cells rely on several survival mechanisms, most cancer cells become highly dependent on MCL-1 for their survival. Therefore, it is hypothesized that targeting the MCL-1 will be a highly targeted strategy specific to cancer cells, and it will leave non-cancer cells unharmed. To some extent, results from clinical and preclinical trials conducted by researchers and drug developers have been able to justify this. Though there remain some limitations such as the emergence of unforeseen adverse effects such as cardiac problems, the potential of MCL-1 as a therapeutic target cannot be denied, and is an avenue that needs to be explored more with potential candidates. Results from preclinical and clinical trials for many promising candidates have returned encouraging outcomes. S63845 was among the first candidates to enter preclinical trials, and to date, it has been assessed in a number of solid and hematopoietic cancers and has shown promising results. Servier and Novartis jointly developed S64315/MIK665, the clinical-trial version of S63845. As mentioned above, MCL-1 inhibitors can act as ideal combinatorial agents. Therefore, S64315 is being assessed in combination with azacitidine, a chemotherapeutic drug, and VOB560, an investigational BCL-2 inhibitor, in patients with hematopoietic cancers.

SUZHOU, China and ROCKVILLE, Md., Dec. 13, 2023 /PRNewswire/ -- Ascentage Pharma (6855.HK), a global biopharmaceutical company engaged in developing novel therapies for cancer, chronic hepatitis B (CHB), and age-related diseases, announced today that it has released updated data from a randomized, controlled, registrational Phase II study of the company's novel drug candidate, olverembatinib (R&D code: HQP1351), in patients with chronic-phase chronic myeloid leukemia (CML-CP) resistant and/or Intolerant to first- and second-generation tyrosine kinase inhibitors (TKIs), in an Oral Presentation at the 65th American Society of Hematology (ASH) Annual Meeting, taking place in San Diego, CA, the United States. Prof. Xiaojun Huang and Prof. Qian Jiang, from the hematology department of Peking University People's Hospital, are the principal investigators of the study. The ASH Annual Meeting is one of the largest gatherings of the international hematology community, bringing together the most cutting-edge scientific research and latest data of investigational therapies that represent leading scientific and clinical advances in the global hematology field. Garnering growing interest from the global research community, multiple studies of Ascentage Pharma's key drug candidates (including olverembatinib and lisaftoclax) have been selected for presentations at this year's ASH Annual Meeting, including two Oral Presentations on olverembatinib. This is the sixth consecutive year in which study results on olverembatinib have been selected for Oral Presentations at the ASH Annual Meeting. Data from this Chinese study (HQP1351CC203) of olverembatinib showed that, in patients with CML-CP resistant and/or intolerant to prior treatment with TKIs, the olverembatinib arm achieved statistically significant improvement in event-free survival (EFS) compared to the control arm that was treated with the best available therapy (BAT), thus meeting the primary endpoint of the study with markedly improved prognosis for patients in the olverembatinib arm, compared to those in the control arm. In November 2023, based on results from this study, the China National Medical Products Agency (NMPA) approved olverembatinib for the treatment of adult patients with CML-CP resistant to and/or intolerant of first- and second-generation TKIs. Olverembatinib is being jointly commercialized in China by Ascentage Pharma and Innovent Biologics. Prof. Qian Jiang, deputy director of the hematology department of Peking University People's Hospital and a principal investigator of the study, commented, "In November 2021, olverembatinib was granted its first marketing authorization that ended the lack of effective treatment for patients with T315I mutant CML in China. However, resistance to TKIs remained a major challenge in the treatment of CML. According to existing clinical data, 30%-50% of patients treated with first- or second-generation TKIs develop resistance/intolerance. These patients have a very poor prognosis due to the lack of effective treatments. The updated data from this randomized, controlled, registrational Phase II study showed that olverembatinib significantly improved the EFS for patients with first- and second-generation TKI-resistant and/or intolerant CML while exhibiting potent efficacy and favorable safety. These results supported the recent approval for an additional indication of olverembatinib. We are confident that, through standardized diagnosis and treatment, olverembatinib will benefit the broader population of patients with CML by better treatment responses earlier and further improving the prognosis of patients with TKI-resistant and/or intolerant CML." Dr. Yifan Zhai, Chief Medical Officer of Ascentage Pharma, said, "Results from this study supported the recent approval for an additional indication of olverembatinib and the selection for Oral Presentation at the ASH Annual Meeting for the sixth consecutive year, which are encouraging achievements that indicated strong recognition for our work. Remaining committed to the mission of the addressing unmet clinical needs in China and around the world, we will expedite our clinical development programs to bring more safe and effective therapies to patients in need." Highlights of the study presented at ASH 2023: Olverembatinib (HQP1351) Demonstrates Efficacy Versus. Best Available Therapy (BAT) in Patients with Tyrosine Kinase Inhibitor-Resistant Chronic Myeloid Leukemia Chronic-Phase in a Registrational Randomized Phase 2 Study Format: Oral Report Abstract: #869 Session: 632. Chronic Myeloid Leukemia: Clinical and Epidemiological: Novel Therapeutic Approaches Time: December 11, 2023, Monday; 3:45 PM (Pacific Time) / December 12, 2023, Tuesday; 7:45 AM (Beijing Time) Highlights: Background: Patients with CML resistant and/or intolerant to first- and second-generation TKIs have a high risk of disease progression and poor prognosis. Results from a Phase I study and a registrational Phase II study of olverembatinib (HQP1351-SJ0002, HQP1351CC201/202) have demonstrated favorable safety, potent antitumor activity, as well as potent inhibitory activity against BCR-ABL1WT and T315I mutations. Moreover, olverembatinib also showed significant inhibitory activity against BCR-ABL1 compound mutations. Methods: The study enrolled patients with CML-CP resistant and/or intolerant to 3 TKIs, including imatinib, dasatinib, and nilotinib, with an ≤ 2 Eastern Cooperative Oncology Group (ECOG) performance score and adequate organ functions. Patients were randomized at a 2:1 ratio to receive olverembatinib (40mg, every other day [QOD]) or BAT (interferon, hydroxyurea, homoharringtonine [HHT], and TKIs [imatinib, dasatinib, and nilotinib] in monotherapy or combinations). The primary endpoint of this study was EFS. After reaching EFS, patients in the BAT arm were allowed to cross-over to the olverembatinib arm for continued treatment. Patients: As of October 17, 2023, a total of 144 patients were enrolled, of whom 96 patients received olverembatinib and 48 received BAT. In the BAT arm, 22 (47.8%) patients received nilotinib; 16 (34.8%) received dasatinib; 2 (4.3%) received imatinib; 2 (4.3%) received nilotinib combined with hydroxyurea; 2 (4.3%) received dasatinib combined with interferon; 1 (2.2%) received nilotinib combined with interferon; and 1 (2.2%) received interferon combined with hydroxyurea and HHT. The median (range) duration of treatment of the olverembatinib arm and the BAT arm were 21.4 (0.6-44.2) months and 2.9 (0.2-40.5) months, respectively. The median (range) duration of follow-up of the two arms were 30.8 (1.3-46.0) months and 30.4 (0-45.8) months, respectively. Efficacy results: Clinical data from this study showed, in patients with CML-CP resistant and/or intolerant to prior treatment with TKIs, the olverembatinib arm achieved statistically significant improvement in EFS compared to the BAT arm, thus reaching the primary endpoint. Compared with the BAT control arm, olverembatinib reduced event risk by 60%. The EFS of the olverembatinib arm at 12, 24, and 36 months were 59% (95% CI, 48-68), 47% (95% CI, 36-57), and 47% (95% CI, 36-57), respectively. Among the 48 patients in the BAT arm, 35 (73%) patients were crossed-over to received olverembatinib after reaching the primary endpoint (25/35 patients were crossed-over 3 months prior to this study). The olverembatinib arm showed a significantly higher cumulative response rate than the BAT arm, as well as durable efficacy. Safety results: In the olverembatinib arm, the median duration of treatment was 21.4 (0.6-44.2) months, and 85.4% of patients experienced grade ≥3 adverse events (AEs). In the BAT control arm, the median duration of treatment was 2.9 (0.2-40.5) months, and 67.4% of patients experienced grade ≥3 AEs. The incidence of grade ≥3 hematologic AEs in the olverembatinib arm declined over time as the treatment went on, and the incidence of grade ≥3 non-hematologic AEs did not increase as the treatment continued. As of October 17, 2023, a total of 98 patients (56 [58.3%] patients in the olverembatinib arm and 42 [87.5%] patients in the BAT control arm) discontinued therapies due to disease progression/treatment failure (13.5% vs 45.8%), AEs (28% vs 31.3%), consent withdrawal (9.4% vs 2.1%), poor compliance (3.1% vs 2.1%), death (1% vs 2.1%), drop-out from follow-up (0%-2.1%), and other reasons (3.1% vs 2.1%). Conclusions: In patients with TKI-resistant and/or intolerant CML, the olverembatinib arm has achieved significantly improvement in EFS (HR=0.4, 95%CI 0.3,0.5), p＜0.001, comparted with the BAT control arm, thus reaching the primary endpoint of the study. In addition, the olverembatinib arm has shown a higher cumulative response rate and longer duration of responses. * Olverembatinib is an investigational drug that has not been approved for any indication outside the Chinese mainland About Ascentage Pharma Ascentage Pharma (6855.HK) is a globally focused biopharmaceutical company engaged in developing novel therapies for cancers, chronic hepatitis B, and age-related diseases.
