In January 2017, Palatin and AMAG Pharmaceuticals agreed that AMAG exclusively would complete development and market bremelanotide in North America and the two would work together to license it in other territories; AMAG agreed to pay $60 million upfront, up to $80 million in regulatory milestones, up to $300 million in sales milestones, and tiered royalties ranging from high single digit to low double digit percentages.A New Drug Application of bremelanotide for female sexual dysfunction was accepted by the U.S. Food and Drug Administration (FDA) in June 2018, with a Prescription Drug User Fee Act (PDUFA) goal date set for 23 March 2019. It was approved for use in the United States in June 2019. References

(Small amounts of a fetuss DNA escapes through the placenta to circulate in the mothers blood.) A genome-wide association study done in China used genome-wide cfDNA analyses to diagnose various chromosome-related disorders including PKS. The study scanned the DNA in the blood of 29,007 pregnant women and found three cases with abnormal amount of DNA originating from the entire p-arm of chromosome 12. All three cases were confirmed to have a fetus with PKS. Two of these cases were missed by chromosomal microarray analysis of the placenta and chorionic villi. However, the study did not define the rate of false negative cases, i.e. negative results in women actually carrying a fetus with PKS. While further studies are required, this method may turn out to be a critically useful addition for the prenatal detection of PKS, particularly during early pregnancies for the purpose of pregnancy options counseling. Postnatal diagnosis
The postnatal diagnosis of PKS is strongly suggested or indicated in most cases based on finding the key defects of PKS in an individual on physical examination and various radiography, ultrasound, and related methods. However, some individuals with this syndrome do not have a sufficient number of these defects or have a set of defects that are also compatible with other birth defect disorders such as Fryns syndrome, trisomy 12p, and Sifrim-Hitz-Weiss syndrome (also termed CHD4 Neurodevelopmental Disorder). The diagnosis can be confirmed in these cases as well as in all cases of PKS by detecting its sSMC using special methods.
