Cabotegravir is an investigational drug that is being studied for the treatment and prevention of HIV infection. Cabotegravir belongs to a class (group) of HIV drugs called integrase inhibitors. Integrase inhibitors block an HIV enzyme called integrase. (An enzyme is a protein that starts or increases the speed of a chemical reaction.) By blocking integrase, integrase inhibitors prevent HIV from multiplying and can reduce the amount of HIV in the body. Cabotegravir does not require boosting with an additional drug. Two forms of cabotegravir are being studied: tablets that are taken by mouth (known as oral cabotegravir or oral CAB) and a long-acting injectable form that is injected into the muscle (known as cabotegravir LA or CAB LA; LA stands for "long-acting"). (A long-acting drug formulation works over a long period of time. Using this type of drug might mean that the drug could be taken less often, making a treatment or prevention regimen simpler to take.) Cabotegravir is in Phase-III clinical trials for HIV infections.

Samidorphan was developed as a sublingually bioavailable µ-opioid receptor antagonist. This drug participated in clinical trials for the treatment of Schizophrenia, Alcohol Dependence, and Binge Eating Disorder. The oral dose pharmacokinetics, safety, and tolerability of samidorphan were evaluated in phase II double blind, placebo-controlled, randomized studies in healthy adults. In addition, the combination of samidorphan (SAM) with buprenorphine (BUP) was studied in phase III clinical trial in patients with major depressive disorder (MDM). It was shown that the long-term treatment did not reveal any new safety findings and confirmed that the risk of abuse and dependence with BUP/SAM was low.
KD025 is an orally available, selective small molecule inhibitor of ROCK2 (Rho-associated coiled-coil kinase 2), a molecular target in multiple autoimmune, fibrotic and neurodegenerative diseases. KD025 is the only ROCK2-specific inhibitor in the clinical trials. KD025 down-regulates the IL-17 and IL-21 secretion in human PBMCs, and leads to down-regulation of STAT3 phosphorylation, IRF4, and RORγt expression in CD4+ T cells. Kadmon Pharmaceuticals initiated phase II clinical trials of KD025 for the treatment of Graft-versus-host disease; Idiopathic pulmonary fibrosis; Plaque psoriasis.

OTL-0038 or OTL-38, a fluorescent-labelled folate receptor-α (FRα) targeted imaging agent that accumulates in vivo in tumor cells expressing FR. OTL38 is currently in ongoing Phase 3 clinical trial in ovarian cancer and successfully completed phase 2 clinical trial in lung cancer. OTL38 is being evaluated for its ability to help surgeons locate and remove hard-to-find cancerous lesions that are often widespread. In 2014, the OTL-38 molecule was granted orphan drug status which can be given to the maker of a drug that treats rare conditions or diseases and offers protection from competition for a period of time. In addition, OTL-38 was studied in phase II clinical trials in the Netherlands for the diagnosis of endometriosis.
Fexinidazole is an antiparasitic drug, which is in the phase III of clinical trial for the treatment of Human African Trypanosomiasis, and in the phase II for the treatment Disease, Chagas and Visceral Leishmaniosis. However, for the Visceral Leishmaniosis, studies were terminated, due to lack of efficacy. Fexinidazole rapidly metabolized to two active metabolites, a sulfone and a sulfoxide, which prolong the pharmacological action of parent drug. These metabolites retaine trypanocidal activity but are less effective in nifurtimox-resistant lines, which can lead to the potential danger in the use of fexinidazole as a monotherapy.
Viloxazine is an antidepressant drug was used to treat patients with depression. Viloxazine inhibits noradrenaline uptake. This drug was approved in some Europe countries, but not in the USA, but then it was discontinued because of competition from other drugs. In the frame of drug repositioning, Viloxazine participated in clinical trials for the treatment of attention deficit hyperactivity disorder. Phase II of trials was successfully passed.

Voclosporin (trans-ISA247) is a Cyclosporin A derivative and immunosuppressive compound currently being investigated for the treatment of psoriasis, lupus nephritis and for the prevention of organ rejection in kidney transplant patients. An animal study showed that a lower blood level of Voclosporin was able to produce a greater or similar inhibition of lymphocyte proliferation, expression of T-cell activation surface antigens, and T-cell cytokine production compared to Cyclosporin A. Voclosporin has been shown to be an efficacious and safe immunosuppressant in phase IIb and phase III trials in renal transplant recipients and in plaque psoriasis patients. In clinical trials, Voclosporin added to standard-of-care induction therapy for lupus nephritis increases complete renal remission (CRR) rates, but higher rates of adverse events including death were observed.
Selpercatinib (LOXO-292, ARRY-192) is a potent and specific RET (c-RET) inhibitor that was granted accelerated FDA approval on May 8, 2020, for specific RET-driven cancer indications. It is currently marketed under the brand name RETEVMO™ by Loxo Oncology Inc.
