Puma Biotechnology, Inc. | March 16, 2023
Puma Biotechnology, Inc., a biopharmaceutical company, recently announced the online publication of the Phase II TBCRC041 randomized clinical trial results in JAMA Oncology. The trial investigated the use of alisertib, an adenosine triphosphate–competitive and reversible inhibitor of aurora kinase A, alone or in combination with fulvestrant in postmenopausal women with endocrine-resistant, HER2-negative metastatic breast cancer who were previously treated with fulvestrant.
The Phase II randomized clinical trial was conducted via the Translational Breast Cancer Research Consortium and included patients previously treated with CDK 4/6 inhibitors and everolimus.
The trial enrolled 91 evaluable patients, with baseline characteristics balanced between the two arms of the trial. However, more patients in the alisertib plus fulvestrant arm had previously received chemotherapy for metastatic disease (47.8% in the alisertib alone arm vs. 68.9% in the alisertib plus fulvestrant arm). In each arm of the trial, all patients had earlier been treated with CDK 4/6 inhibitors. Everolimus was previously administered to 37% of patients in the alisertib alone arm and 57.8% in the alisertib plus fulvestrant arm.
The trial's efficacy results indicated that nine partial responses were observed in the 46 evaluable patients in the alisertib alone arm, leading to an overall response rate of 19.6%. The median duration of response was 15.1 months, with a clinical benefit rate of 41.3% at 24 weeks. The projected median progression-free survival (PFS) was 5.6 months. Nine of the 45 evaluable patients in the alisertib plus fulvestrant arm of the study responded, for an overall response rate of 20.0%. There was one patient who had a complete response and eight patients who showed partial responses. The median duration of response was 8.5 months, with a clinical benefit rate of 28.9% at 24 weeks. The median PFS was expected to be 5.4 months.
The most prevalent grade 3 or higher adverse events in the alisertib alone arm of the trial were neutropenia (43.4%), anemia (19.6%) and leukopenia (17.4%). The most prevalent grade 3 or higher adverse events in the alisertib plus fulvestrant arm of the study were neutropenia (42.2%), leukopenia (31.1%), lymphopenia (15.6%), fatigue (11.1%), and anemia (8.9%).

Magenta Therapeutics, Inc. and Dianthus Therapeutics, Inc. a privately-held, clinical-stage biotechnology company dedicated to advancing the next generation of antibody complement therapeutics, announced today that they have entered into a definitive merger agreement to combine the companies in an all-stock transaction. The combined company will focus on advancing Dianthus’ pipeline of next-generation complement inhibitors, including DNTH103 currently in a Phase 1 clinical trial. Upon completion of the merger, the combined company is expected to operate under the name Dianthus Therapeutics, Inc. and trade on the Nasdaq under the ticker symbol “DNTH”.
In support of the merger, Dianthus has secured commitments for a $70 million private investment in its common stock and pre-funded warrants from a syndicate of healthcare investors led by Fidelity Management & Research Company, Catalio Capital Management, 5AM Ventures, Avidity Partners, Wedbush Healthcare Partners and founding investors Fairmount, Tellus BioVentures and Venrock Healthcare Capital Partners, that is expected to close immediately prior to completion of the merger. With the cash expected from both companies at closing and the proceeds of the concurrent private financing, the combined company is expected to have approximately $180 million of cash or cash equivalents immediately post-closing. The cash resources are intended to be used to advance Dianthus’ pipeline through multiple clinical data catalysts and is expected to fund operations into mid-2026. The merger and related financing are expected to close in the third quarter of 2023.
“I’m delighted to announce this planned merger with Magenta, which comes at a pivotal moment in the evolution of our company as we advance our pipeline of next-generation complement therapeutics for people living with severe autoimmune diseases,” said Marino Garcia, President and Chief Executive Officer of Dianthus Therapeutics. “Gaining access to the public capital markets can enhance our financial strength and fuel our growth strategy, enabling us to unlock the full potential of our pipeline, including our plans to address multiple autoimmune disorders with our clinical-stage active C1s inhibitor, DNTH103.”
“After a thorough exploration of our strategic alternatives, management and our Board of Directors believe the transaction with Dianthus Therapeutics will culminate in a successful outcome for our stockholders,” said Steve Mahoney, President, Chief Financial and Operating Officer of Magenta. “Dianthus has made rapid progress in developing and advancing DNTH103 into the clinic where it has the potential to be a transformative classical pathway inhibitor for severe autoimmune diseases. We are extremely grateful to our current and former employees who contributed to Magenta’s efforts to develop its programs and we now look forward to the combined company’s advancement on opportunities for value creation for patients.”

Pharming Group N.V. announces the first commercial shipments of Joenja® to patients in the United States. Joenja®, an oral, selective PI3Kδ inhibitor, is the first and only treatment approved in the U.S. for activated phosphoinositide 3-kinase delta (PI3Kδ) syndrome (APDS), a rare and progressive primary immunodeficiency, in adult and pediatric patients 12 years of age and older.
Under the terms of Pharming's 2019 exclusive license agreement with Novartis for leniolisib, the corresponding first commercial sale of Joenja® triggers a $10 million milestone payment by Pharming to Novartis.
Stephen Toor, Chief Commercial Officer of Pharming, commented
"We are pleased to announce that the first Joenja® shipments to patients, with payor reimbursement, were delivered approximately two weeks following FDA approval, achieving an important milestone for patients suffering with APDS. We look forward to making Joenja® widely available across the U.S. as the first and only approved treatment for patients with APDS."
About Activated Phosphoinositide 3-Kinase δ Syndrome (APDS)
APDS is a rare primary immunodeficiency that was first characterized in 2013. APDS is caused by variants in either one of two identified genes known as PIK3CD or PIK3R1, which are vital to the development and function of immune cells in the body. Variants of these genes lead to hyperactivity of the PI3Kδ (phosphoinositide 3-kinase delta) pathway, which causes immune cells to fail to mature and function properly, leading to immunodeficiency and dysregulation.1,2,3 APDS is characterized by a variety of symptoms, including severe, recurrent sinopulmonary infections, lymphoproliferation, autoimmunity, and enteropathy.4,5 Because these symptoms can be associated with a variety of conditions, including other primary immunodeficiencies, it has been reported that people with APDS are frequently misdiagnosed and suffer a median 7-year diagnostic delay.6 As APDS is a progressive disease, this delay may lead to an accumulation of damage over time, including permanent lung damage and lymphoma.4-7 A definitive diagnos
is can be made through genetic testing. APDS affects approximately 1 to 2 people per million worldwide.
