Below is a look at some of the headlines for companies that made news in the healthcare sector on October 30, 2014.
Immunomedics, Inc., (Nasdaq:IMMU) announced isactuzumab govitecan (IMMU-132), the Company's proprietary solid-tumor antibody-drug conjugate (ADC), continues to produce encouraging results in a Phase 2 clinical trial in heavily-pretreated patients with diverse, metastatic solid cancers. The provisional results were presented by Dr. David M. Goldenberg, Chairman, Chief Scientific Officer, and Chief Medical Officer, at the 5th Annual World ADC Summit in San Diego, CA.
In 113 patients who have received at least one dose of isactuzumab govitecan, treatments with the ADC resulted in at least 64 patients (57%) with partial responses and disease stabilization. All lesions were measured by computed tomography (CT) based on RECIST 1.1 criteria. The major responses were observed among patients with 6 different advanced cancers, including triple-negative breast, small-cell and non-small-cell lung, colorectal, esophageal, and urinary bladder cancers.
The ADC was well tolerated at the Phase 2 dose used in the trial expansion, with neutropenia being the major toxicity, and about 10% of patients having grade 3 and 4 other toxicities. This suggests a higher therapeutic index (ratio of therapeutic benefit to toxicity) than historical results with irinotecan, SN-38's parent compound.
"We are most encouraged with the results in patients with triple-negative breast cancer, small-cell and non-small-cell lung cancers, especially in these patients who have late-stage diseases," remarked Cynthia L. Sullivan, President and Chief Executive Officer. "We plan to complete the Phase 2 study before the end of this year. Discussions with key opinion leaders, as well as potential corporate partners, on the further development of this valuable agent are ongoing," Ms. Sullivan added.
Isactuzumab govitecan is made up of SN-38, the active metabolite of irinotecan, conjugated to the Company's humanized anti-TROP-2 antibody. TROP-2 is expressed by many human tumors, such as cancers of the breast, cervix, colon and rectum, kidney, liver, lung, ovary, pancreas, and prostate, but with only limited expression in normal human tissues. Preclinical studies have indicated that isactuzumab govitecan delivers up to 135-times the amount of SN-38 to a human pancreatic tumor xenograft than when irinotecan is given. In patients who relapsed or were refractive to prior topoisomerase I or II inhibitors, this ADC demonstrated subsequent activity, suggesting that it can overcome resistance to such inhibitors, including irinotecan.
In addition to isactuzumab govitecan (IMMU-132), the Company is also developing another SN-38 based ADC, labetuzumab govitecan (IMMU-130), for the treatment of patients with metastatic colorectal cancer. The clinical study of this agent is advancing into a Phase 2 trial, with some patients under therapy for many months and showing long-term disease control after failing prior irinotecan-containing regimens. Here again, despite the frequent dosing, the ADC appears to be well tolerated by patients, with transient and reversible neutropenia, and manageable diarrhea the major side effects, which were mild and irregular.
Hemispherx Biopharma, Inc. (NYSE MKT:HEB), reported a new peer reviewed publication entitled, "The Quest for Effective Ebola Treatment; Ebola VP35 is an Evidence-Based Target for dsRNA Drugs" in the Nature Group's current issue of Emerging Microbes and Infections (October 29, 2014). This publication was authored by affiliates of Hemispherx. The publication provides an illustration of the crystallographic coordinates of a truncated VP35 complex with dsRNA.
Death from Ebola virus (EBOV) infection is associated with markedly impaired coagulation and innate immunity cascades, increased production of pro-inflammatory cytokines, profound immune suppression resulting in peripheral T lymphocyte apoptosis, and a lack of adaptive immunity (Fields Virology 923-956, 2013). By contrast, survivors of infection by EBOV develop an effective immune response with the production of EBOV neutralizing antibodies. Early events in EBOV infection influence the patient's ability to develop an effective immune response. The success of EBOV replication is dependent on viral inhibition of initial innate immune responses to infection. Disarming innate immune responses is a common mechanism employed by highly pathogenic human viruses, including those of the influenza and coronavirus families (Antiviral Res 100:615, 2013). EBOV is one of the more successful of the emerging highly pathogenic viruses in evasion of innate immune mechanisms.
Critical Role of VP35 in High Death Rates -- VP35 is a multifunctional major virulence protein that is indispensable for EBOV replication. Double-stranded RNA (dsRNA) is a necessary component of viral replication, which initiates systemic signaling cascades that normally activate interferon (IFN) regulatory factors leading to the production of IFN-α/β (type I IFNs). VP35 inhibition of dsRNA effectively disarms essential components of the innate immune response. VP35 binds to sequence-independent dsRNA, resulting in the suppression of multiple steps in the IFN signaling cascade, which otherwise would provide a broad antiviral state by activation of both the innate and adaptive arms of the immune response. Multiple investigators have demonstrated that VP35 binds dsRNA (Antiviral Res93:354, 2012) and molecular crystallographic analysis has demonstrated that binding is achieved by non-covalent bonding with the dsRNA phosphodiester backbone and thus shielding of viral produced dsRNA from host antiviral signaling pathways (Nat Struct Mol Biol 17:165, 2010). The inavailability of viral produced dsRNA during replication results in an increased virus load and its consequences. Thus, the VP35 dsRNA interaction is an evidence-based target for antiviral interruption of EBOV, potentially ameliorating the pathogenesis of EVD.
Therapeutic dsRNA May Overcome the Lethal dsRNA Sequestration Action of VP35 and Reverse the "dsRNA Deficiency" Associated with Ebola -- Various forms of dsRNA have been studied as inducers of type I IFNs. Although the original dsRNA studied for efficacy in humans, poly I:poly C, was found to induce serious adverse events in humans that limited pharmaceutical development, several derivatives have survived the rigors of animal and clinical testing. Poly I:Poly C12U (rintatolimod, Ampligen®) was designed as an IFN inducer with a markedly reduced incidence of adverse events compared to the parent compound poly I:poly C and has demonstrated antiviral activity against a wide variety of DNA and RNA viruses in pre-clinical testing, including SARS (Severe Acute Respiratory Syndrome). Multiple mechanisms may be involved in the antiviral activity of rintatolimod in its predicted EBOV utility. These include direct induction of innate immunity as a TLR3 agonist, competition for VP35 binding with dsRNA allowing activation of innate immune responses, and/or serve as a required dsRNA cofactor for IFN induced enzymes that function in the innate immune cascades triggered by viral infections. In contrast to drugs under intensive development to help contain this global crisis, sequestration of dsRNA is non-sequence dependent with the phosphodiester backbone freely available for VP35 binding. Since EBOV has been demonstrated to be mutating rapidly in this epidemic (Science 345:1369, 2014), anti-EBOLA agents that depend on sequence maintenance (vaccines, monoclonal antibodies, active site viral enzyme inhibitors) may be at risk following clinical development even with crisis activated reductions in regulatory requirements.
A Secondary Efficacy Mechanism -- In animal studies, Ampligen® was also efficacious by a second mechanism as an adjuvant for highly pathogenic avian influenza virus vaccines, and this drug is now being evaluated as an adjuvant in a variety of cancer vaccine trials. Epitope expansion has also been observed with Ampligen® applied intranasally in man (Vaccine 32(42):5490, 2014) and this property may also result in antibody levels to accelerate recovery from Ebola and evade mutational inhibitory properties.
Evidence Based Experimental Therapeutics -- The use of experimental pharmaceuticals beyond phase I in FDA-sanctioned clinical trials helps ensure the availability of products with established safety profiles sufficient for open-label clinical testing and analysis of efficacy. The use of potential drugs already in clinical trials also helps ensure a reliable supply of clinical- grade drugs, which removes the ethical dilemma of patient selection for treatment (New England J Med 371:1066, 2014). In third world countries, with limited facilities for medical intervention, protecting the individual from exposure to Ebola containing bodily fluids may be achieved by heightening immunity on the majority of mucosal surfaces, as by the potential use of intranasal sprays of Ampligen®. Hemispherx is working with regulatory authorities to potentially inhibit further escalation of this global crisis.
On September 29, 2014, Hemispherx announced a series of collaborations designed to determine the potential effectiveness of Alferon® N and Ampligen® as potential preventative and/or therapeutic treatments for Ebola related disorders (http://www.hemispherx.net/content/investor/default.asp?goto=800 ).
