Clinical Catch-Up: March 23-27


The COVID-19 pandemic continues to dominate the news and is likely to for quite some time. The biopharma industry is doing what it can to test and repurpose therapies, develop diagnostics and respond to the crisis. Also, although some clinical trials are being slowed or halted, others are reporting out data. Here’s a look.

World Health Organization is organizing the SOLIDARITY clinical trial to create data that can be leveraged to decide which treatments are most effective, if they decrease mortality and hospital stays. It will have five arms, one standard of care, one Gilead’s remdesivir, one a combination of lopinavir/ritonavir, another a combination of lopinavir/ritonavir/interferon beta, and the fifth of chloroquine. At least 10 countries are participating.

Researchers ran a trial of 55 people in China with mild cases of COVID-19 and 13 severe cases. The goal was to determine if the cytotoxic lymphocytes in patients with the disease were exhausted—these cytotoxic lymphocytes are necessary to control viral infections, and functional exhaustion of them is linked to disease progression. The short answer is: yes, “the function of NK and CD8+ cells was exhausted with the increased expression of NKG2A in COVID-19 patients. Importantly, in patients convalescing after therapy, the number of NK and CD8+ cells were restored with reduced expression of NKG2A.” Patients were administered AbbVie’s Kaletra in about 94.12% of patients, and chloroquine phosphate was used in 7.35%, with 64.71% receiving interferon (IFN). About half also received antibiotic treatment. The researchers believe that by targeting NKG2A with various therapies, which might include checkpoint inhibitors and other drugs, they may be able to prevent the functional exhaustion of the cytotoxic lymphocytes.

IHU-Mediterranee Infection in Marseille, France researchers published an article in the International Journal of Antimicrobial Agents describing the potential use of a combination of hydroxychloroquine and the antibiotic azithromycin, which is better known as Z-Pak. The U.S. Food and Drug Administration (FDA) is also evaluating the drugs but have not yet made recommendations. The French study, which is very small, “showed a significant reduction of the viral carriage” after six days of treatment and “much lower average carrying duration” compared to patients receiving other treatment. Six patients in the trial were asymptomatic and 22 had upper respiratory tract infection symptoms. Eight patients had lower respiratory tract infections. Twenty cases were treated in the study, with untreated patients acting as negative controls.

Biohaven Pharma announced a successful meeting with the FDA at the end of its Phase II trial of intranasal vazegepant for acute treatment of migraine. It plans to initiate a Phase III for the treatment. Vazegepant is part of Biohaven’s NOJECTION Migraine Platform.

Imstem Biotechnology reported the FDA had lifted the clinical hold and cleared the IND application for its IMS001 for multiple sclerosis. The drug is an investigational, allogeneic cell product given intravenously to patients with MS. It expects to initiate a Phase I trial in relapsing/remitting, secondary, and primary progressive forms of MS in 2020 in the US.

AbbVie and Genentech’s Phase III VIALE-A trial of Venclexta (venetoclax) in combination with azacytidine versus azacytidine in combination with placebo met its dual primary endpoints of statistically significant improvement of overall survival (OS) and composite complete remission rate in previously-untreated acute myeloid leukemia (AML) patients who are not eligible for intensive chemotherapy. The independent Data Monitoring Committee recommended the positive efficacy results should be reported early and the data submitted to the FDA and other regulators. Venclextra is a first-in-class drug that selectively binds and inhibits the BCL-2 protein.

AnHeart Therapeutics announced that the Chinese Drug Evaluation Agency cleared its IND and Clinical Trial Authorization (CTA) for two Phase II trials of taletrectinib. The first will be in first- and second-line non-small cell lung cancer (NSCLC) with ROS1 mutations. The second will be in patients with locally advanced or metastatic solid tumors with NTRK mutations. Taletrectinib is a next-generationl selective ROS1 and NTRK inhibitor.

CytoDyn announced that two more patients were treated for COVID-19 using the company’s leronlimab. They are being treated under an emergency IND at a New York hospital. Leronlimab is a viral-entry inhibitor that blocks CCR5.

Novavax announced positive topline data from its pivotal Phase III clinical trial of NanoFlu, its seasonal flu vaccine. The primary objectives were non-inferior immunogenicity of NanoFlu compared to Sanofi’s Fluzone Quadrivalent based on several 28-day metrics.

Vero Biotech treated the first person with COVID-19 and complicating pulmonary hypertension with its proprietary inhaled nitric oxide (iNO) delivery system, GENOSYL DS at home. The patient was treated under an emergency IND. Genoxyl is indicated to improve oxygenation and reduce the need for extracorporeal membrane oxygenation in neonates with hypoxic respiratory failure associated with clinical or echocardiographic evidence of pulmonary hypertension in conjunction with ventilator support and other therapies.

Rafael Pharmaceuticals enrolled more than 75% of the 500 patients needed for its pivotal Phase III trial for metastatic pancreatic cancer (AVENGER 500). The trial is studying the efficacy and safety of CPI-613 (devimistat) in combination with modified FOLFIRINOX (mFFX) as first-line therapy. Devimistat is a first-in-class drug that targets the mitochondrial tricarboxylic acid (TCA) cycle, which is essential to tumor cell multiplication and survival.

Seelos Therapeutics announced additional interim data from its Phase I studies of Intranasal Racemic Ketamine (SLS-002). It also completed its Type C meeting with the FDA to discuss the protocol design for the study of the drug for Acute Suicidal Ideation and Behavior (ASIB) in patients with Major Depressive Disorder (MDD). All vital signs related adverse events were mild and transient. No serious adverse events were observed.

Eloxx Pharmaceuticals temporarily paused enrollment in its Phase II clinical trials for ELX-02 in cystic fibrosis because of the COVID-19 pandemic. ELX-02 is a small molecule drug candidate designed to restore production of full-length functional proteins.
