Angiotensin (1-7) [Ang 1-7] is a 7 amino acid peptide generated predominantly from Ang II by the action of Ang-converting enzyme 2. Ang 1-7 can act as a negative modulator of aldosterone secretion in vitro and in vivo. The endogenous heptapeptide angiotensin-(1-7) (Ang-(1-7)) is a RAS component that has a central role in the alternative axis. It is generated by the cleavage of Ang-II by the action of the angiotensin converting enzyme 2 (ACE 2) and acts via interaction with the G-protein coupled receptor Mas. Angiotensin (1-7) induces vasorelaxation through release of NO and prostaglandins, perhaps through activation of a non-AT1, non-AT2 receptor, Mas. Counteracts the vasoconstrictive and proliferative effects of angiotensin II and stimulates vasopressin (anti-diuretic hormone) release in vivo. Clinical uses range from treatment of cardiovascular-related diseases, ocular pathologies, metabolic dysfunctions, brain conditions and degenerative diseases to applications in cell differentiation and hematopoiesis, tumor therapy, acute lung injury, fibrosis, infection, among others. Tarix Orphan is developing TXA127 for rare neuromuscular and connective tissue diseases. TXA127 is a pharmaceutical formulation of the naturally occurring peptide, Angiotensin (1-7). TXA127 has been effective in animal models of Duchenne muscular dystrophy (DMD), Limb-girdle muscular dystrophy (LGMD), congenital muscular dystrophy MDC1A, Marfan syndrome, and Dystrophic Epidermolysis Bullosa (DEB). FDA granted rare pediatric disease designation to TXA127 from Tarix to treat recessive dystrophic epidermolysis bullosa (RDEB). TXA127 has been granted orphan drug status by FDA as a treatment for pulmonary arterial hypertension, to enhance engraftment in patients receiving a stem cell transplant, and for Myelodysplastic Syndrome (MDS). Tarix Orphan has broad IP protection for TXA127 and Orphan Drug Designations (ODDs) have been granted for DMD LGMD and DEB in the U.S., and for DMD in Europe. Tarix Orphan aims to initiate a clinical trials for both DMD and DEB in early 2018 and has an active IND for a Phase II trial in DMD, as well as Fast Track designation for DMD.

Nelipepimut-S (formerly known as E75) is an immunogenic peptide from the HER2 protein that is highly expressed in breast cancer. The NeuVax™ (Galena, OR, USA) vaccine, nelipepimut-S plus granulocyte-macrophage colony-stimulating factor, is designed for the prevention of clinical recurrences in high risk, disease-free breast cancer patients. Nelipepimut-S is being developed by Sellas Life Sciences Group. When combined with the immunoadjuvant granulocyte-macrophage colony-stimulating factor (GM-CSF), nelipepimut-S has been used as a vaccine that is capable of eliciting a robust anti-HER2 immune response. Early-phase clinical trials that enrolled women with node-positive or high-risk node-negative breast cancer who had been rendered disease free with standard of care therapy but were at risk for recurrence, demonstrated the vaccine to be safe with a suggestion of clinical benefit. Nelipepimut-S is currently being evaluated in a Phase III clinical trial.

Aviptadil, a vasoactive intestinal polypeptide, is a vasodilator and lowers blood pressure if administered intravenously. In 2007, the orphan designation was granted by the European Commission for aviptadil for the treatment of sarcoidosis, a disease of unknown cause that affects many organs and tissues, most commonly the lungs. Sarcoidosis is characterized by specific microscopic lesions called granulomas. Aviptadil is able to influence the immune system that decreases the inflammatory processes seen in sarcoidosis by acting on the white blood cells (lymphocytes and monocytes) involved in the formation of the granulomas. In combination with phentolamine, the drug is used to treat erectile dysfunction. In addition, aviptadil has been studied in phase II clinical trials for patients with respiratory distress syndrome.

Rusalatide acetate (also known as chrysalin or TP 508) is a 23-amino acid peptide derived from human prothrombin; it represents part of the receptor-binding domain of the human thrombin molecule. Rusalatide acetate binds to high-affinity thrombin receptors and mimics cellular effects of thrombin at sites of tissue injury. Rusalatide acetate demonstrated safety and potential efficacy in phase I/II clinical trials for the treatment of diabetic foot ulcers. It interacts with cell surface receptors to stimulate a cascade of cellular and molecular wound healing events, including activation of nitric oxide signaling. In addition, this drug participated in phase II clinical trial to determine the effectiveness of four doses for treating broken wrists in adults. However, this study was terminated because the drug did not demonstrate benefit compared to placebo. Rusalatide acetate was also studied as a cardiovascular drug. However, in January 2012, Capstone discontinued the development of rusalatide, for financial reasons. Recent studies show that a single injection of TP508 (rusalatide acetate) administered 24 h after irradiation significantly increases survival and delays mortality in murine models of acute radiation mortality. Thus, this drug is being developed as a potential nuclear countermeasure.
