This phase I trial tests the safety, side effects, and best dose of triapine in combination with radiation therapy in treating patients with glioblastoma or astrocytoma that has come back after a period of improvement (recurrent). Triapine may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Giving triapine in combination with radiation therapy may be safe, tolerable, and/or effective in treating patients with recurrent glioblastoma or astrocytoma.

A Phase 1 Adaptive Dose Escalation With Dose Expansion Study of Triapine in Combination With Temozolomide (TMZ) for Patients With Recurrent Glioblastoma

This phase I trial tests the safety, side effects, and best dose of triapine in combination with temozolomide in treating patients with glioblastoma that has come back after a period of improvement (recurrent). Triapine inhibits an enzyme responsible for producing molecules required for the production of deoxyribonucleic acid (DNA), which may inhibit tumor cell growth. Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill tumor cells and slow down or stop tumor growth. Giving triapine in combination with temozolomide may be safe, tolerable, and/or effective in treating patients with recurrent glioblastoma.

A Phase II Randomized Control Trial of Triapine Plus Lutetium Lu 177 Dotatate Versus Lutetium Lu 177 Dotatate Alone for Well-Differentiated Somatostatin Receptor-Positive Neuroendocrine Tumors

This phase II trial compares the effect of adding triapine to lutetium Lu 177 dotatate versus lutetium Lu 177 dotatate alone (standard therapy) in shrinking tumors or slowing tumor growth in patients with neuroendocrine tumors that have spread from where they first started (primary site) to other places in the body (metastatic). Triapine may stop the growth of tumor cells by blocking some of the enzymes needed for deoxyribonucleic acid synthesis and cell growth. Lutetium Lu 177 dotatate is a radioactive drug. It binds to a protein called somatostatin receptor, which is found on some neuroendocrine tumor cells. Lutetium Lu 177 dotatate builds up in these cells and gives off radiation that may kill them. It is a type of radioconjugate and a type of somatostatin analog. Giving triapine in combination with lutetium Lu 177 dotatate may be more effective at shrinking tumors or slowing tumor growth in patients with metastatic neuroendocrine tumors than the standard therapy of lutetium Lu 177 dotatate alone.

Article

Author: Randall, Leslie M ; Vargo, John ; Kohn, Elise C ; Orr, Brian ; Ivy, S Percy ; Courtney-Brooks, Madeleine ; Mahdi, Haider ; Lin, Yan ; Behr, Sarah ; Fabian, Denise ; Beriwal, Sushil ; Gallion, Holly ; Richardson, Debra L ; Chu, Edward ; Beumer, Jan H ; Kunos, Charles ; Huang, Marilyn ; Taylor, Sarah E ; Ueland, Frederick ; Girda, Eugenia ; Olawaiye, Alexander B ; Chauhan, Aman ; Sullivan, Stephanie A ; Cooper, Kristine L ; Christner, Susan M

BACKGROUND:

The addition of IV triapine to chemoradiation appeared active in phase I and II studies but drug delivery is cumbersome. We examined PO triapine with cisplatin chemoradiation.

METHODS:

We implemented a 3 + 3 design for PO triapine dose escalation with expansion, starting at 100 mg, five days a week for five weeks while receiving radiation with weekly IV cisplatin for locally advanced cervical or vaginal cancer. Maximum tolerated dose (MTD), dose limiting toxicity (DLT), adverse events, pharmacokinetics (PK), pharmacodynamics (PD), and metabolic complete response (mCR) were assessed.

RESULTS:

19/21 patients were DLT evaluable. DLTs included grade 4 neutropenia (n = 2), leukopenia (n = 2), lymphopenia (n = 2), and hypokalemia (n = 1). Grade 3 toxicities at least possibly related were as expected for cisplatin chemoradiation: lymphopenia (n = 12), anemia (n = 10), neutropenia (n = 4), leukopenia (n = 8), decreased platelets (n = 2), hypertension (n = 1), and hyponatremia (n = 1). MTD and RP2D were established at 100 mg. 8/13 evaluable patients had a mCR. Triapine had a bioavailability of 59%. Methemoglobin levels correlated with triapine exposure. Smoking almost doubled CYP1A2 mediated triapine clearance.

CONCLUSIONS:

Oral triapine is safe when given with cisplatin chemoradiation, convenient, bioavailable. Exposure is negatively impacted by smoking, and methemoglobin is a biomarker of exposure.

Incorporation of triapine (T) to cisplatin chemoradiation (CRT) for locally advanced cervical and vaginal cancer: Results from NRG-GY006, a phase III randomized trial

Article

Author: Feddock, Jonathan M ; Deng, Wei ; Mell, Loren K ; Monk, Bradley J ; Chino, Junzo P ; Amarnath, Sudha R ; Arend, Rebecca C ; Walker, Joan L ; Santos-Reyes, Luis Javier ; Kunos, Charles M ; Ghamande, Sharad A ; Albuquerque, Kevin ; Lea, Jayanthi S ; Aghajanian, Carol ; Jegadeesh, Naresh ; Chon, Hye Sook ; DiSilvestro, Paul ; Richardson, Debra L ; Mayadev, Jyoti ; Donnelly, Eric ; Holman, Laura L ; MacKay, Helen ; Gao, Lei ; Quick, Allison M ; Lowenstein, Jessica ; Leath, Charles A

BACKGROUND:

Cisplatin-based chemoradiation (CRT) plus brachytherapy for locally advanced cervical cancer (LACC) is standard. Intrinsic overexpression of ribonucleotide reductase (RNR) may enhance DNA damage repair from CRT. We report on outcomes of adding RNR inhibitor, triapine (T), to CRT.

METHODS:

NRG-GY006 is an open-label randomized phase III trial. FIGO 2009 LACC (stages IB2, II, IIIB or IVA) without para-aortic nodal involvement or stages II-IV vaginal cancer were eligible. Random assignment to CRT or in combination with thrice-weekly T (CRT + T) occurred. Radiation consisted of either 3D conformal (3DCRT) or image-guided intensity modulated RT (IG-IMRT) followed by intracavitary brachytherapy. Primary endpoint was overall survival (OS). Progression-free survival (PFS) was secondary. Exploratory endpoints included complete metabolic response rate on post treatment PET/CT imaging and comparative toxicity and outcomes for 3DCRT vs. IG-IMRT.

FINDINGS:

Four-hundred-fifty patients were randomized including 448 eligible (224 in CRT and 224 in CRT + T). Median age was 47 (range 23-85). The majority had cervical cancer (93.3 %) with squamous histology (82 %). 52 % had FIGO stage II disease. Racial/ethnic distribution included non-Hispanic white (53.8 %), black (15.2 %) and Hispanic/Latina (22.5 %). At randomization, IG-IMRT was planned in 74.3 % and HDR brachytherapy in 98.2 %. No differences in Grade 3-5 toxicities were observed: CRT: 52 % and CRT + T: 49 %, with two G5 toxicities (cardiac arrest and acidosis) in the CRT + T arm. The median patient follow-up was 28 months (IQR 15-45). HR for death was 1.018 (95 % CI 0.634-1.635) while HR for progression was 1.021 (95 % CI 0.694-1.501).

INTERPRETATION:

Triapine added to CRT did not improve OS.

Opposing effects of mycotoxins alternariol and deoxynivalenol on the immunomodulatory effects of oxaliplatin and triapine

Article

Author: Kowol, Christian R ; Gufler, Judith ; Hager, Sonja ; Heffeter, Petra ; Marko, Doris

Mycotoxin occurrence in food worldwide is estimated to increase due to climate change. Moreover, studies on how these food contaminants interfere with medications and especially anticancer therapies are rare. With the rise of anticancer immunotherapies, particularly mycotoxins with immunomodulatory activity, such as alternariol (AOH) or deoxynivalenol (DON), are of great concern. Both mycotoxins interfere with the pro-inflammatory nuclear factor kappa B (NF-κB) pathway in myeloid cells. This pathway not only plays an important role in the anticancer immune response but also inflammatory side effects induced by chemotherapeutic drugs. Consequently, the aim of this study was to investigate possible beneficial or detrimental immunomodulatory interactions between these mycotoxins and anticancer drugs. To assess the combined influence of mycotoxins and anticancer therapies on immune cell stimulation, THP-1 NF-κB reporter cells were utilized as monocytes as well as differentiated and polarized macrophages. Parameters for activation (NF-κB activity and protein expression), differentiation (CD14 and CD71 surface marker expression) and polarization (interleukin 10 (IL10), interleukin 8 (CXCL8), tumor necrosis factor α (TNF), prostaglandin-endoperoxide synthase 2 expression and CXCL8 secretion) were assessed upon combinatory treatment. Both mycotoxins affected the immunostimulatory effects of the pre-selected anticancer drugs oxaliplatin and triapine, although in opposing directions. While AOH generally suppressed a drug-induced activation and increased anti-inflammatory IL10 levels, DON potentiated activation and pro-inflammatory markers, such as CXCL8 and TNF in immune cells. In conclusion, AOH and DON have the potential to alter the immunological effects of anticancer therapies, which should be considered during therapy as well as in their future risk assessment.

Nanopharmaceutics, Inc. Announces the End of Patient Recruitment for the National Cancer Institute (NCI) Sponsored Phase 3 Clinical Study in Advanced-Stage Cervical and Vaginal Cancers with Cisplatin During Radiation Therapy with and without Triapine®

ALACHUA, Fla., Nov. 2, 2022 /PRNewswire/ -- Nanopharmaceutics, Inc., a clinical-stage pharmaceutical development company, today announced completion of patient enrollment in the 450 patient Phase 3 clinical study sponsored by the NCI, part of the National Institutes of Health, and led by NCI funded network group, NRG Oncology, with participation of the NCI National Clinical Trials Network (NCTN), "A Randomized Phase III Trial of Radiation Therapy and Cisplatin Alone or in Combination with Intravenous Triapine in Women with Newly Diagnosed Bulky Stage IB2, Stage II, IIIB, or IVA Cancer of the Uterine Cervix or Stage II-IVA Vaginal," (NRG-GY006, ClinicalTrials.gov Identifier: NCT02466971). The randomized phase 3 trial is evaluating radiation therapy and cisplatin with Nanopharmaceutics' proprietary formulation of Triapine® compared to the standard radiation therapy and cisplatin, alone, in treating patients with newly diagnosed stage IB2, II, or IIIB-IVA cervical cancer or stage II-IVA vaginal cancer. Radiation therapy uses high energy protons to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, stopping them from dividing, or by stopping them from spreading. Triapine® may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether radiation therapy and cisplatin are more effective with Triapine® Injection in treating cervical or vaginal cancer. 450 patients were enrolled in the study, which was performed under a Cooperative Research and Development Agreement (CRADA) between NCI and Nanopharmaceutics. About Triapine® Triapine® is a synthetic heterocyclic carboxaldehyde thiosemicarbazone with potential antineoplastic activity being studied in the treatment of cancer. It is a type of ribonucleotide reductase inhibitor. Also called 3-aminopyridine-2-carboxaldehyde thiosemicarbazone and 3-AP, Triapine® inhibits the enzyme ribonucleotide reductase, resulting in the inhibition of the conversion of ribonucleoside diphosphates to deoxyribonucleotides necessary for DNA synthesis.
