This investigator-initiated trial conducted by the Vall d’Hebron Institute of Oncology (VHIO) in Barcelona, Spain, is sponsored by the Osteosarcoma Institute (OSI; View Source), whose mission is to dramatically increase treatment options and survival rates in osteosarcoma patients through identifying and funding the most promising and breakthrough osteosarcoma clinical trials and science. Dr. Lee Helman, Director of the OSI, commented that MYC amplification/overexpression occurs in a subset of patients with osteosarcoma and there is mounting evidence that this may be associated with a poor outcome. We are grateful for the opportunity to support a study evaluating the use of a MYC inhibitor in collaboration with VHIO and Peptomyc." The OSI is a science-driven organization whose strategy is guided by its active and engaged Strategic Advisory Board (SAB) of preeminent physicians and other researchers from academia and industry. We would like to acknowledge OSI SAB members William Tap, MD; Katherine Janeway, MD, MMSc; Brian Crompton, MD, Lara Davis, MD, and Chand Khanna, DVM, PhD for their expert contributions to the development of this clinical trial.

"We are extremely grateful to the OSI and VHIO for this study and we are thrilled to expand our OMO-103 clinical program with the initiation of a third clinical trial for this candidate, underscoring OMO-103’s potential versatility across a broad range of solid tumors," commented Dr. Laura Soucek, Chief Executive Officer of Peptomyc. "Patients with advanced osteosarcoma, a rare type of bone cancer affecting predominantly children, adolescents, and young adults have an extremely poor prognosis, highlighting the need for novel treatment regimens to combat this highly aggressive disease. With MYC representing a bad prognostic for osteosarcoma patients – potentially resulting in resistance to standard of care treatment – we believe that inhibiting MYC could have a significant anti-tumor effect in this dismal disease."

Dr. Claudia Morales Valverde, Senior Researcher of the Genitourinary, Central Nervous System (CNS) Tumors, Sarcoma and Cancer of Unknown Primary Site Group at the Vall d’Hebron Institute of Oncology (VHIO) in Barcelona and Principal Investigator of the trial said, "This is the first use of a MYC inhibitor in osteosarcoma patients and we are eager to conduct this seminal study at the Vall d’Hebron University Hospital. MYC is especially amplified in osteosarcomas and our study will include at least 30% of patients below the age of 18, highlighting the importance of pediatric, adolescent, and adult specialists’ collaboration."

Dr. Manuela Niewel, Chief Medical Officer of Peptomyc, added, "I am really excited to test OMO-103 in this underserved patient population and hopefully make a change in their disease outcome. "

The Phase 2 trial (OSTEOMYC) aims at evaluating the safety and clinical activity, pharmacodynamics, and pharmacokinetics of OMO-103 in advanced osteosarcoma. The primary efficacy endpoint is progression-free survival (PFS) at 16 weeks per RECIST criteria. Secondary endpoints include Overall Response Rate (ORR) per RECIST and overall survival. The trial is enrolling patients at Vall d’Hebron University Hospital in Barcelona, Spain. More information about the trial is available at:

About Osteosarcoma

Osteosarcoma, while rare, is the most common type of bone cancer and is often associated with a high degree of malignancy, early metastasis, rapid progression, and poor prognosis. This cancer occurs primarily in children, adolescents, and young adults ranging from 10 to 30 years of age. The risk of diagnosis decreases in adulthood but rises again in older adults, usually over the age of 60. Approximately 3 new cases/million population are diagnosed each year. Treatment typically includes surgery and chemotherapy, with chemotherapy administered before and after surgery to help lower the risk of relapse. Even though curative therapy is available for the primary tumor, long-term outcomes for osteosarcoma patients continue to be impacted by metastatic progression and few improvements have been achieved in the last 40 years.

About MYC

MYC is the most dysregulated oncogene in human cancer, controlling multiple transcriptional programs associated to most hallmarks of cancers, including increased proliferation, metastatic potential, immune suppression, and resistance to treatment.

About OMO-103

OMO-103 is a first-in-class and best-in-class mini-protein against MYC. It has successfully been tested in a Phase Ia study in all-comers solid tumors and is currently in a Phase Ib study in metastatic pancreatic ductal adenocarcinoma (mPDAC) patients in combination with standard of care chemotherapy.

On January 16, 2025 GT Medical Technologies, Inc. (GT MedTech), a medical device company with a corporate purpose of improving the lives of patients with brain tumors, reported the company has completed a $37 million first close of a Series D financing round (Press release, GT Medical Technologies, JAN 16, 2025, View Source [SID1234649756]).

The financing was led by Evidity Health Capital, alongside new investor Accelmed Partners. Also participating were existing investors MVM Partners, Gilde Healthcare and Medtech Venture Partners. The funds will accelerate the completion of the ROADS clinical study that is focused on GammaTile for newly diagnosed brain metastases, and the GESTALT clinical trial for patients with newly diagnosed glioblastomas (GBMs). In addition, the funds will support the continued commercialization of GammaTile, the Company’s FDA cleared bioresorbable radiotherapy implant for the treatment of brain tumors.

In conjunction with the financing, Adam Lessler, MD, Partner at Evidity Health Capital, and Camilo Rico, Vice President at Accelmed Partners, will join GT MedTech’s Board of Directors.

"Since 2019, doctors across the country have chosen GammaTile as a proven treatment for patients with operable brain tumors," said Per Langoe, Chief Executive Officer at GT MedTech. "With the support of Evidity and Accelmed, we are well-positioned to expand the availability of GammaTile and advance our ongoing clinical studies to continue transforming brain tumor treatment."

By delivering tile-based radiation therapy directly into the surgical cavity at the time of tumor removal, GammaTile provides immediate, localized treatment. This approach targets remaining cancer cells when they are at their lowest levels to help prevent regrowth while minimizing radiation exposure to healthy brain tissue.

"The Series D financing round underscores the confidence investors have in GammaTile Therapy and our vision to innovate brain tumor care," added Sandeep Yadav, Chief Financial Officer of GT MedTech. "We are thrilled to welcome Adam and Camilo to our Board of Directors as we enter this next phase of growth."

On January 15, 2025 Handa Pharmaceuticals, Inc. ("Handa") (6620.TWO) announced that its U.S. subsidiary, Handa Therapeutics, LLC (the "Company"), has acquired PHYRAGO (dasatinib) tablets, a U.S. Food and Drug Administration ("FDA") approved chronic myeloid leukemia treatment that was developed by Nanocopoeia, LLC (Press release, Nanocopoeia, JAN 15, 2025, View Source [SID1234650016]). PHYRAGO is the first and only dasatinib product that can be co-administered with gastric acid-reducing agents. An estimated one-third of patients who require SPRYCEL treatment may also take gastric acid-reducing agents1, which can reduce dasatinib’s drug exposure by more than 40% when taken with a proton pump inhibitor and more than 60% when taken with an H2 receptor antagonist2.

PHYRAGO was granted Orphan-Drug Designation and has received three (3) years of data exclusivity that will expire December 5, 2026. Should PHYRAGO be granted Orphan-Drug Exclusivity, it may be eligible for seven (7) years of exclusivity, until December 5, 2030. PHYRAGO is protected by several issued patents, including those listed in the FDA’s Approved Drugs and Therapeutic Equivalents publication (the "Orange Book") that expire January 22, 2041.

The Company is in the process of selecting a U.S. commercialization partner and expects PHYRAGO to be available to patients in Q1-2025.

PHYRAGO is indicated for adult patients with newly diagnosed Philadelphia chromosome positive chronic myeloid leukemia (Ph+ CML) in chronic phase and adult patients with Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL) who no longer benefit from, or did not tolerate, other treatments.

"PHYRAGO represents a novel dasatinib formulation that delivers equivalent efficacy to SPRYCEL, with the additional benefit of allowing patients to take dasatinib with gastric acid-reducing agents", said Bill Liu, Chairman and CEO of Handa. "Unlike SPRYCEL, PHYRAGO allows concomitant use with a proton pump inhibitor or H2 receptor antagonist."

The effect of co-administration of gastric acid-reducing agents on SPRYCEL is significant. The SPRYCEL label warns that the "co-administration of SPRYCEL with a gastric acid-reducing agent may decrease the concentration of dasatinib. Decreased dasatinib concentrations may reduce efficacy. Do not administer H2 agonists or proton pump inhibitors with SPRYCEL."3

The FDA approved PHYRAGO with a label that allows co-administration with gastric acid-reducing agents, stating that "No clinically significant differences in the pharmacokinetics of PHYRAGO were observed following concomitant use with omeprazole (proton pump inhibitor) or famotidine (H2 receptor antagonist)."4 and "Avoid concomitant use of PHYRAGO with antacids. If concomitant use of an antacid cannot be avoided, administer the antacid at least 2 hours prior to or 2 hours after the dose of PHYRAGO."5

According to Bristol Myers Squibb’s annual report, net sales of SPRYCEL in 2023 totaled $1.44 billion. For full prescribing information about PHYRAGO, please visit www.phyrago.com.

The China subpopulation results were consistent with those in the global population:

TIVDAK demonstrated a 45% reduction in the risk of death compared to chemotherapy (HR: 0.55 [95% CI: 0.27-1.15] in the China subpopulation who had received prior standard systemic therapies, with more than half of this Chinese population having received prior anti-PD(L)1 therapy. Median OS for patients treated with TIVDAK was not reached versus chemotherapy 10.7 months [95% CI: 6.0-not reached] with a median follow-up of 11.5 months.
Secondary endpoints of PFS and confirmed ORR also favored treatment with TIVDAK compared to chemotherapy.
The safety profile of TIVDAK in the China subpopulation was manageable and consistent with the global profile.
"Recurrent or metastatic cervical cancer remains a significant challenge for patients, highlighting a critical unmet need for effective treatments that extend survival after relapse," said Dr. Rafael Amado, M.D., President, Head of Global Research and Development at Zai Lab. "The consistent and positive results in the China subpopulation of the global Phase 3 study reinforce the potential for TIVDAK, the only ADC therapy in this disease setting, to increase options in this therapeutically unmet clinical setting. If approved, we expect TIVDAK to add to ZEJULA and augment our commercial franchise in women’s tumors."

"There are approximately 150,000 new cases of cervical cancer annually in China1, and patients face limited treatment options once their cancer recurs or spreads after initial treatment," said Dr. Lingying Wu, Professor of the Department of Gynecologic Oncology of National Cancer Center / Cancer Hospital Chinese Academy of Medical Sciences. "While the recent adoption of immunotherapy as a first-line treatment in China represents progress, there is a lack of effective options for patients following relapse. The promising results from TIVDAK, which demonstrated superior survival extension in patients whose disease progressed after initial treatments, including prior anti-PD(L)1 treatment, offer hope for addressing this critical unmet need."

In April 2024, the U.S. Food and Drug Administration (FDA) approved the supplemental Biologics License Application (sBLA) granting full approval for TIVDAK (tisotumab vedotin-tftv) for the treatment of patients with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy. The approval was based on results from the global, randomized, Phase 3 innovaTV 301 clinical trial (NCT04697628), which met its primary endpoint, demonstrating overall survival (OS) benefit in adult patients with previously treated recurrent or metastatic cervical cancer treated with TIVDAK compared to chemotherapy.

TIVDAK demonstrated a 30% reduction in the risk of death compared to chemotherapy (hazard ratio [HR]: 0.70 [95% CI: 0.54-0.89], two-sided p=0.0038)2. Median OS for patients treated with TIVDAK was 11.5 months [95% CI: 9.8-14.9] versus chemotherapy 9.5 months [95% CI: 7.9-10.7].
PFS and confirmed ORR were also significantly improved compared to chemotherapy.
The safety profile of TIVDAK was consistent with its known safety profile as presented in the U.S. prescribing information, and no new safety signals were observed.
Based on these encouraging results, Zai Lab intends to submit an NDA for TIVDAK to China’s National Medical Products Administration (NMPA) in the first quarter of 2025. The full China subpopulation data will be presented at a future medical conference in 2025.

About innovaTV 301 Trial Design

The innovaTV 301 trial (NCT04697628) is a global, 1:1 randomized, open-label Phase 3 trial evaluating TIVDAK (tisotumab vedotin) versus investigator’s choice of single agent chemotherapy (topotecan, vinorelbine, gemcitabine, irinotecan, or pemetrexed) with recurrent or metastatic cervical cancer who received chemotherapy.

Patients with recurrent or metastatic cervical cancer with squamous cell, adenocarcinoma, or adenosquamous histology, and disease progression during or after treatment with chemotherapy doublet +/- bevacizumab and an anti-PD-(L)1 agent (if eligible) are included. The primary endpoint was overall survival. The main secondary outcomes were progression-free survival and objective response rate.

The study was conducted by Seagen, which was acquired by Pfizer in December 2023, in collaboration with Genmab, European Network of Gynaecological Oncological Trial Groups (ENGOT, study number ENGOT cx-12) and the Gynecologic Oncology Group (GOG) Foundation (study number GOG 3057), as well as other global gynecological oncology cooperative groups.

About Cervical Cancer in China

Cervical cancer remains one of the leading causes of cancer death in women in China and globally. An estimated 150,000 new cases of cervical cancer occur annually in China1. Current treatment options are limited for patients with recurrent or metastatic cervical cancer with disease progression on or after systemic therapy. TIVDAK is well positioned to provide a new option for previously treated advanced cervical cancer patients who currently have limited treatment options and poor outcomes.

About TIVDAK (tisotumab vedotin)

TIVDAK (tisotumab vedotin) is an antibody-drug conjugate (ADC) composed of Genmab’s human monoclonal antibody directed to tissue factor (TF) and Pfizer’s ADC technology that utilizes a protease-cleavable linker that covalently attaches the microtubule-disrupting agent monomethyl auristatin E (MMAE) to the antibody. Nonclinical data suggest that the anticancer activity of tisotumab vedotin is due to the binding of the ADC to TF-expressing cancer cells, followed by internalization of the ADC-TF complex, and release of MMAE via proteolytic cleavage. MMAE disrupts the microtubule network of actively dividing cells, leading to cell cycle arrest and apoptotic cell death. In vitro, tisotumab vedotin also mediates antibody-dependent cellular phagocytosis and antibody-dependent cellular cytotoxicity.

TIVDAK received accelerated approval from the FDA in September 2021 and full approval in April 2024 for adult patients with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy.

Please see full prescribing information, including BOXED WARNING for TIVDAK here.

Zai Lab has an exclusive license from Seagen Inc., a company later acquired by Pfizer, to develop and commercialize TIVDAK in Greater China (mainland China, Hong Kong, Macau, and Taiwan, collectively).
