DCFPYL F-18 is an urea-based radiotracer composed of the prostate-specific membrane antigen (PSMA)-targeting agent DCFPyL and labeled with the positron-emitting isotope, fluorine F 18, that can potentially be used for positron-emitting tomography (PET) imaging. Upon administration of fluorine F 18 DCFPyL, the DCFPyL moiety binds to PSMA expressed on tumor cells. The fluorine F 18 moiety facilitates PET imaging of PSMA-expressing tumor cells. DCFPYL F-18 is investigated in a number of clinical trials in patients with prostate cancer and neuroendocrine tumors.

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.

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.
Bristol-Myers Squibb developed Rimegepant, also known as BMS-927711. Rimegepant is a potent, selective, competitive and orally active calcitonin gene-related peptide (CGRP) antagonist in clinical trials for treating migraine. Rimegepant has shown in vivo efficacy without vasoconstrictor effect; it is superior to placebo at several different doses (75 mg, 150 mg, and 300 mg) and has an excellent tolerability profile.

Prostamedix is a 68Ga-labeled ligand of the prostate-specific membrane antigen (PSMA) for Prostate Cancer PET imaging. Because of the increased expression of PSMA in Prostate Cancer and its metastases, Prostamedix was reported to exhibit a favorable lesion-to-background ratio with high detection rates. Further studies evaluating Prostamedix showed substantially higher detection rates in patients with recurrent PC than reported for other imaging modalities, especially at low PSA values. The chelator HBED-CC (N,N'-bis-[2-hydroxy-5-(carboxyethyl)benzyl]ethylenediamine-N,N'-diacetic acid), represents a hitherto rarely used acyclic complexing agent especially allowing efficient radiolabelling with 68Ga even at ambient temperature. By combining HBED-CC with the PSMA inhibitor Glu-urea-Lys, a favorable aromatic part is introduced into the radiotracer which was found to be a necessary requirement for sustainable interaction with the PSMA receptor, putatively with the accessory hydrophobic pocket of the PSMA

Setmelanotide (RM-493), is an investigational, first-in-class melanocortin-4 receptor (MC4R) agonist in development for the treatment of rare genetic disorders of obesity. Setmelanotide is thought to activate the MC4R, part of a key biological pathway in humans that regulates weight by increasing energy expenditure and reducing appetite. Variants in genes within the MC4 pathway are associated with unrelenting hunger, known as hyperphagia, and severe, early-onset obesity. Setmelanotide is a potential replacement therapy that may restore lost activity in the MC4 pathway, reestablishing weight and appetite control in patients with these rare genetic disorders.
ODM-201 (also known as BAY-1841788) is a non-steroidal antiandrogen, specifically, a full and high-affinity antagonist of the androgen receptor (AR), that is under development by Orion and Bayer HealthCare for the treatment of advanced, castration-resistant prostate cancer (CRPC). ODM-201 appears to negligibly cross the blood-brain-barrier. This is beneficial due to the reduced risk of seizures and other central side effects from off-target GABAA receptor inhibition that tends to occur in non-steroidal antiandrogens that are structurally similar to enzalutamide. Moreover, in accordance with its lack of central penetration, ODM-201 does not seem to increase testosterone levels in mice or humans, unlike other non-steroidal antiandrogens. Another advantage is that ODM-201 has been found to block the activity of all tested/well-known mutant ARs in prostate cancer, including the recently-identified clinically-relevant F876L mutation. ODM-201 has been studied in phase I and phase II clinical trials and has thus far been found to be effective and well-tolerated, with the most commonly reported side effects including fatigue, nausea, and diarrhea. No seizures have been observed.

Gallium edotreotide Ga-68 is a radioconjugate consisting of the octreotide derivative edotreotide labeled with gallium 68 (Ga-68). Similar to octreotide, gallium Ga 68-edotreotide binds to somatostatin receptors (SSTRs), especially type 2 receptors, present on the cell membranes of many types of neuroendocrine tumor cells and their metastases, thereby allowing for imaging of SSTR-expressing cells with positron emission tomography (PET). Gallium edotreotide Ga-68 has been authorized in the EU as SomaKit for the diagnosis of gastro-entero-pancreatic neuroendocrine tumors. It was investigated in clinical trials for imaging of brain tumors, pituitary tumors and neuroendocrine tumors of various origin.
