In a BIO Digital session on “The Convergence of Health and Tech: Personalizing Medicine Beyond the Imaginable,” panelist Ray Deshaies, Amgen Inc.’s senior vice president of global research, said he was excited for the future of drug research, noting that there is an evolving trend away from the development of monospecific drugs designed to exert their effect on just one specific target. The early stage product pipelines of biopharma companies are now adding bi- or multispecific drug candidates that exert an influence on several mechanisms in the cell, either simultaneously or sequentially. He noted that this is a sea change that is beginning to sweep over the industry. Biopharma companies are now beginning to uncover ways to counteract unwanted disease-causing proteins that have previously been difficult to block using a single small-molecule drug approach.

Product development

The FDA sent a complete response letter to Allergan plc, an Abbvie Inc. company, and Molecular Partners AG regarding the BLA for abicipar pegol, their VEGF-A inhibitor-Darpin therapy for patients with wet age-related macular degeneration. In the letter, the FDA noted the rate of intraocular inflammation occurring after administering abicipar pegol 2 mg/0.05 mL results in an unfavorable benefit-risk ratio. Abbvie said it will meet with the FDA to discuss the comments and determine next steps.

Chiasma Inc. secured U.S. approval for Mycapssa, the first oral formulation of the acromegaly medicine octreotide to get a regulatory green light. Octreotide has until now only been available by injection. The drug was approved for long-term maintenance treatment in acromegaly patients who have responded to and tolerated treatment with octreotide or lanreotide, both somatostatin analogues.

Xpovio (selinexor), an oral selective inhibitor of nuclear transport from Karyopharm Therapeutics Inc., received FDA approval for treating adults with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), including DLBCL arising from follicular lymphoma, after at least two lines of systemic therapy. The drug will be available immediately in the U.S., the company said, and, due to COVID-19 restrictions, the launch will be a virtual one.

A second attempt by Nabriva Therapeutics plc to win U.S. approval for the antibiotic Contepo (fosfomycin) has been undone by COVID-19. Manufacturing issues stymied the original NDA. This time, restrictions of FDA staff travel to Europe sunk the venture, leading to a new complete response letter (CRL) for the candidate as a potential treatment of complicated urinary tract infections, including acute pyelonephritis. The company warned of the potential for the CRL in May. The agency did not request any new clinical data, nor did it raise any other concerns about the safety or efficacy of Contepo in the CRL.

The FDA approved Zogenix Inc.’s Fintepla (fenfluramine), an oral treatment for patients ages 2 and older with seizures associated with Dravet syndrome, a rare, pediatric-onset form of epilepsy.

COVID-19 developments

Two months after the launch, the World Health Organization (WHO) has laid out the spending plans for its push to accelerate development and production of COVID-19 vaccines, therapeutics and diagnostics.

The consolidated investment case calls for $31.3 billion over the next 12 months, of which $3.4 billion has been contributed to date. The money will accelerate development and fund delivery of 500 million diagnostic tests and 245 million courses of therapies to poorer countries by mid-2021, with 2 billion doses of vaccine, of which 1 billion will go the poorer countries to be delivered by the end of 2021. The investment is significant, but WHO said the total cost is less than a 10th of the $375 billion the global economy is losing every month due to the pandemic.

A new U.K. trial evaluating drugs for hospitalized patients in the early stages of COVID-19 has elected to test Evelo Biosciences Inc.'s anti-inflammatory monoclonal microbial, EDP-1815, after an earlier trial found it led to favorable anti-inflammatory activity in psoriasis patients. Interim data from the trial, called TACTIC-E, are anticipated during the fourth quarter. If results of the phase II/III study are positive, Evelo said its team will engage with regulators to determine if the data support registration. Glenmark Pharmaceuticals Ltd. has been granted manufacturing and marketing approval for the launch of its antiviral drug, favipiravir, for the treatment of mild to moderate COVID-19, a move it deems a “landmark development for COVID-19 patients in India.” Glenmark filed the product for use in clinical trials with the Drug Controller General of India (DCGI) and became the first pharmaceutical company in India to receive approval to conduct a phase III study in patients with mild to moderate disease caused by the SARS-CoV-2 virus.

Applied Biology Inc. said that a team of scientists, while studying the genetics of the androgen receptor in male pattern baldness, discovered a possible breakthrough treatment for COVID-19. Immunoprecise Antibodies Ltd. and Litevax BV will collaborate on a preclinical study to analyze the immunogenicity, safety and potency of Immunoprecise's SARS-CoV-2 vaccine candidates. Orgenesis Inc. entered a preliminary, nonbinding term sheet with Leidos Holdings Inc. to develop Orgenesis’ ranpirnase to treat severe acute respiratory syndrome associated with SARS-CoV-2. Ranpirnase catalyzes the degradation of RNA and mediates several biological activities, including regulation of cell proliferation, maturation, differentiation and cell death. Moderna Inc. and Catalent Inc. will collaborate on large-scale, commercial fill-finish manufacturing of Moderna’s mRNA-based COVID-19 vaccine candidate, mRNA-1273, at Catalent’s biologics facility in Bloomington, Ind. Catalent will provide vial filling, packaging capacity and additional staffing required for round-the-clock manufacturing operations to produce an initial 100 million doses of the vaccine candidate intended to supply the U.S. market starting in the third quarter of 2020. Palatin Technologies Inc. is developing melanocortin 1 receptor agonist PL-8177 as a treatment for patients with COVID-19 after a preclinical test in multiple inflammatory disease models and a lung injury model showed it reduced inflammation, protected lung tissue and reduced lung fibrosis. Schrödinger Inc. said it is expanding its work to discover new antiviral therapies for COVID-19. The company is leading the computational design work in an alliance of major biopharma companies collaborating on the COVID-19 initiative, including Takeda Pharmaceutical Co. Ltd., Novartis AG, Gilead Sciences Inc. and Wuxi Apptec.

Regulatory news

The FDA reported it has launched Project Patient Voice (PPV), created by the agency's Oncology Center of Excellence. The PPV website provides publicly available information describing patient-reported symptoms from cancer trials for marketed treatments. While those data have historically been analyzed by the FDA during the drug approval process, they are rarely included in product labeling and, therefore, are largely inaccessible to the public. The data can provide additional, complementary information for health care professionals, specifically when discussing the potential side effects of a cancer treatment. In the first phase of the pilot website, only one trial will be included while the FDA seeks public feedback on how the information is presented. It will use that feedback to consider improvements to the website in order to make the information as user-friendly as possible.

The FDA has finalized its guidances on the clinical development of drugs to treat community-acquired bacterial pneumonia (CAPB) and hospital-acquired and ventilator-associated bacterial pneumonia (HABP/VABP). They discuss the overall development program and clinical trial designs for drugs to support an indication of CAPB or HABP/VABP.


Word on the Street: Industry responses to the issues of the week

“In terms of launching in the virtual environment, given the pandemic started in Q1, we've known for quite some time that a virtual launch would be necessary, and we've been preparing accordingly. All of our field teams have been provided additional tools to virtually engage with customers. We rapidly launched multiple digital tools to facilitate continued sales force engagement with customers, and the field team has been trained on how to utilize these tools with the appropriate promotional pieces in DLBCL.”
Ian Karp, Karyopharm Therapeutics Inc.’s vice president of investor and public relations, speaking on conference call to investors about the FDA approval of Xpovio (selinexor), an oral selective inhibitor of nuclear transport for treating adults with relapsed or refractory diffuse large B-cell lymphoma

"While these agents have demonstrated efficacy in a proportion of cancer patients, there clearly is room for improvement to lift the tail of the curve."
Michele Teng, associate professor at the QIMR Berghofer Medical Research Institute, told the audience at the clinical trials plenary session of the American Association for Cancer Research Virtual Annual Meeting II, where researchers presented data from a pair of immunotherapies looking to build on the success targeting PD-(L)1

"In the tissue-agnostic approvals to date, we believe that based on the biology and clinical results, that we can infer clinical effects across a wide variety of tumors. The chance of each rare biomarker-positive tumor responding will be higher than the chance that a specific tumor type will be inherently resistant."
Steven Lemery, acting director of the division of oncology at the FDA, speaking at a session of the American Association for Cancer Research Virtual Annual Meeting II, noting that if a resistance was found in a certain tumor type, the label could be modified to note the exception
