FDA Approves Orserdu (elacestrant) for Patients with ESR1 Mutations in ER+, HER2- Advanced or Metastatic Breast Cancer

The Menarini Group (“Menarini”), a leading Italian pharmaceutical and diagnostics company, announced  the U.S. Food and Drug Administration (FDA)   approval of  Orserdu for the treatment of postmenopausal women or adult men, with ER+, HER2-, ESR1-mutated advanced or metastatic breast cancer with disease progression following at least one line of endocrine therapy. Stemline Therapeutics (“Stemline”), a wholly-owned subsidiary of the Menarini Group, headquartered in New York and focused on bringing transformational oncology treatments for cancer patients, will commercialize Orserdu in the U.S.




“The FDA approval of Orserdu marks the first ever therapy for ER+, HER2- advanced or metastatic breast cancer patients with ESR1 mutations and we are very proud to offer a targeted therapy addressing this huge unmet need,” commented Elcin Barker Ergun, Chief Executive Officer of the Menarini Group. “We are grateful to the patients, investigators and administrators who participated in the clinical trials that led to this remarkable innovation.”

Orserdu is approved under the FDA’s Priority Review and Fast Track designation based on the results of the registrational Phase III trial EMERALD, that demonstrated statistically significant progression-free survival (PFS) with elacestrant vs SOC endocrine monotherapy (fulvestrant, letrozole, anastrozole, exemestane), meeting both primary endpoints in all patients and in those patients whose tumors harbor ESR1 mutations.

In the group of patients whose tumors had ESR1 mutations, elacestrant reduced the risk of progression or death by 45% (PFS HR=0.55, 95% CI: 0.39, 0.77) vs SOC. A post-hoc analysis of the PFS results based on the duration of prior CDK4/6i inhibitors (CDK4/6i) usage was presented at San Antonio Breast Cancer Symposium (SABCS) in December 2022. The median PFS was 8.6 months on elacestrant vs 1.9 months for SOC, in those patients whose tumors harbored ESR1 mutations and had been treated with a CDK4/6i for at least 12 months.

Safety data is consistent with the other endocrine therapies. Most of the adverse events (AEs), including nausea and musculoskeletal pain were grade 1 and 2. No hematological safety signal was observed and none of the patients in either of the two treatment arms had sinus bradycardia.

“Advanced or metastatic ER+, HER2- breast cancer pre-treated with endocrine-based therapy remains an area of unmet medical need. The last endocrine therapy approved was about 20 years ago, and effective endocrine options for this patient population are needed,” said Dr. Aditya Bardia, MD, MPH, Director of Breast Cancer Research at Mass General Cancer Center, Associate Professor at the Medicine Department at Harvard Medical School, and Principal Investigator for the EMERALD trial. “ESR1 mutations are a known driver of resistance to standard endocrine therapy, and so far, have been difficult to treat. The approval of elacestrant is welcomed as it offers a novel option for patients with ER+, HER2- metastatic breast cancer. This therapy targets the ESR1 mutations in metastatic breast cancer and provides patients with a convenient oral once-daily dose.

“Each year 300,000 Americans are diagnosed with breast cancer and metastatic breast cancer causes the vast majority of deaths from the disease: more than 43,000 annually. We urgently need new and better treatment options to extend and improve the lives of people with metastatic breast cancer,” said Sonya Negley, Executive Director, Metavivor. “We are thrilled to see the approval of Orserdu, a new oral endocrine therapy, for patients who have tumors that harbor ESR1 mutations, which are present in up to 40% of ER+, HER2- advanced or metastatic breast cancer. We advise patients to get tested for ESR1 mutations at progression in their metastatic treatment, so that their healthcare team can identify the right treatment options for their disease.“

Agios Announces FDA Approval of Tibsovo as Monotherapy for Newly Diagnosed Adult Patients with IDH1 Mutant Acute Myeloid Leukemia (AML) Not Eligible for Intensive Chemotherapy


TIBSOVO├é® (ivosidenib) Structural Formula Illustration


Agios Pharmaceuticals, Inc., a leader in the field of cellular metabolism to treat cancer and rare genetic diseases,  announced the U.S. Food and Drug Administration (FDA) approved a supplemental New Drug Application (sNDA) to update the U.S. Prescribing Information for Tibsovo, an isocitrate dehydrogenase-1 (IDH1) inhibitor, to include adult patients with newly diagnosed acute myeloid leukemia (AML) with a susceptible IDH1 mutation as detected by an FDA-approved test who are ≥ 75 years old or who have comorbidities that preclude use of intensive induction chemotherapy. The sNDA was granted Priority Review and accepted under the FDA's Real-Time Oncology Review pilot program, which aims to make the review of oncology drugs more efficient by allowing the FDA access to clinical trial data before the information is formally submitted to the agency. Tibsovo received initial FDA approval in July 2018 for adult patients with relapsed or refractory (R/R) AML and an IDH1 mutation1.
“Despite several new AML medicines approved in the last two years, many newly diagnosed patients are still not eligible for existing therapies or combination regimens because of age and other comorbidities,” said Chris Bowden, M.D., chief medical officer at Agios. “With today’s additional Tibsovo approval, we are now able to provide a targeted, oral therapy to patients with an IDH1 mutation who may not have other treatment options. In addition, we are continuing our work to expand the utility of Tibsovo in newly diagnosed AML patients in ongoing Phase 3 trials in combination with both intensive chemotherapy and azacitidine. I would like to thank the patients, nurses, physicians and caregivers who participated in the clinical trial, as well as the tremendous employees at Agios whose focus on patients made this possible.”
AML is a cancer of the blood and bone marrow marked by rapid disease progression and is the most common acute leukemia affecting adults with approximately 20,000 new cases estimated in the U.S. each year2,3. AML patients are typically older or have comorbidities that preclude the use of intensive chemotherapy4. These patients typically have a worse prognosis and poor outcomes5. The majority of patients with AML eventually relapse6. The five-year survival rate is approximately 28%2. For 6 to 10 percent of AML patients, the mutated IDH1 enzyme blocks normal blood stem cell differentiation, contributing to the genesis of acute leukemia7. IDH1 mutations have been associated with negative prognosis in AML.
“The Phase 1 results for Tibsovo demonstrated that this oral, single agent therapy can induce durable responses in newly diagnosed AML patients with an IDH1 mutation,” said Gail J. Roboz, M.D., Professor of Medicine, Director of the Leukemia Program and a member of the Sandra and Edward Meyer Cancer Center at Weill Cornell Medicine and NewYork-Presbyterian/Weill Cornell Medical Center*. “Many patients included in the study had features associated with particularly aggressive and challenging forms of AML, including secondary disease, adverse risk genetics and prior treatment with hypomethylating agents.”
Tibsovo Safety and Efficacy Data
The efficacy of Tibsovo was evaluated in an open-label, single-arm, multicenter clinical trial (Study AG120-C-001, NCT02074839) that included 28 adult patients with newly diagnosed AML with an IDH1 mutation who were assigned to receive a 500 mg daily dose. The cohort included patients who were age 75 or older or had comorbidities that precluded the use of intensive induction chemotherapy (baseline Eastern Cooperative Oncology Group [ECOG] performance status of ≥2, severe cardiac or pulmonary disease, hepatic impairment with bilirubin >1.5 times the upper limit of normal, or creatinine clearance <45 mL/min). Patients had a median age of 77 years (range of 64 to 87) and 68% had AML with myelodysplasia-related changes. The primary endpoint is the combined complete remission (CR) and complete remission with partial hematologic improvement (CRh) rate. CRh is defined as <5% of blasts in the bone marrow, no evidence of disease and partial recovery of peripheral blood counts (platelets >50,000/microliter and ANC >500/microliter).
In this trial, Tibsovo demonstrated:
  • CR+CRh rate of 42.9% (12 of 28 patients) (95% CI: 24.5, 62.8).
  • The CR rate was 28.6% (8 of 28 patients) (95% CI 13.2, 48.7) and the CRh rate was 14.3% (4 of 28 patients) (95% CI 4.0, 32.7).
  • Median durations of CR and CR+CRh were not estimable, with 5 patients (41.7%) who achieved CR or CRh remaining on Tibsovo treatment (treatment duration range: 20.3 to 40.9 months) as of the data cutoff.
  • 58.3% (7 of 12) of patients who achieved CR or CRh were in remission at 1 year after receiving treatment.
  • For patients who achieved a CR or CRh, the median time to best response of CR or CRh was 2.8 months (range, 1.9 to 12.9 months).
  • Among the 17 patients who were dependent on red blood cell (RBC) and/or platelet transfusions at baseline, 7 (41.2%) became independent of RBC and platelet transfusions during any 56-day post-baseline period.
  • Of the 11 patients who were independent of both RBC and platelet transfusions at baseline, 6 (54.5%) remained transfusion independent during any 56-day post-baseline period.
The safety profile of single-agent Tibsovo was evaluated in 28 patients with newly diagnosed AML with an IDH1 mutation treated with a dose of 500 mg daily. The median duration of exposure to Tibsovo was 4.3 months (range, 0.3 to 40.9 months). In the clinical trial, 25% (7 of 28) of patients treated with Tibsovo experienced differentiation syndrome, which can be fatal if not treated. Of the 7 patients with newly diagnosed AML who experienced differentiation syndrome, 6 (86%) patients recovered. QTc interval prolongation occurred in patients treated with Tibsovo. The most common adverse reactions (≥20%) of any grade in patients with newly diagnosed AML were diarrhea, fatigue, decreased appetite, edema, nausea, leukocytosis, arthralgia, abdominal pain, dyspnea, myalgia, constipation, differentiation syndrome, dizziness, electrocardiogram QT prolonged, mucositis and vomiting.

FDA Approves Lonsurf (trifluridine/tipiracil) for Adult Patients with Previously Treated Advanced Gastric or Gastroesophageal Junction (GEJ) Adenocarcinoma

In continuation of my update on Lonsurf

Trifluridine and tipiracil.svg
Taiho Oncology, Inc.  announced that the United States Food and Drug Administration (FDA) has approved Lonsurf as a treatment for adult patients with metastatic gastric or gastroesophageal junction adenocarcinoma previously treated with at least two prior lines of chemotherapy that included a fluoropyrimidine, a platinum, either a taxane or irinotecan, and if appropriate, HER2/neu-targeted therapy.
“The approval of Lonsurf represents a significant milestone for patients living with advanced gastric or GEJ adenocarcinoma who have limited effective treatment options after standard treatment options have failed,” said Timothy Whitten, President and Chief Executive Officer, Taiho Oncology, Inc. “We thank all the patients and physicians who helped make this possible through their participation in Lonsurf clinical trials.”
The approval for Lonsurf follows an FDA Priority Review designation and is based on data from a global, randomized, Phase III TAGS trial evaluating Lonsurf plus best supportive care (BSC) versus placebo plus BSC in patients with previously treated advanced gastric cancer or GEJ adenocarcinoma following progression or intolerance to previous lines of standard therapy. The trial met its primary and secondary endpoints demonstrating prolonged overall survival (OS) with Lonsurf versus placebo, and a safety profile consistent with prior experience with this drug. Full results from the TAGS trial were presented at the European Society of Medical Oncology (ESMO) 2018 Congress with a simultaneous publication in The Lancet Oncology.1
“Effective treatments for patients with heavily pretreated advanced gastric and GEJ cancer are limited,” said Martin Birkhofer, MD, Senior Vice President and Chief Medical Officer, Taiho Oncology, Inc. “By improving survival, Lonsurf may provide a significant impact on the lives of these patients.”
This approval expands the current indication for Lonsurf in the United States, where it is currently approved for the treatment of patients with metastatic colorectal cancer (mCRC) who have been previously treated with standard chemotherapy, based on results obtained in the RECOURSE trial.
