FDA grants orphan drug status for Lipocine’s LPCN 1107 to prevent preterm birth
Specialty pharmaceutical firm Lipocine has received orphan drug designation from the US Food and Drug Administration (FDA) for its LPCN 1107 to prevent preterm birth (PTB).

LPCN 1107 is an oral product candidate of 17-alpha hydroxyprogesterone caproate under development for the indication of prevention of recurrent preterm birth. LPCN 1107 has the potential to become the first oral HPC product for the prevention of preterm birth in women with a prior history of at least one preterm birth. Potential benefits of our oral product candidate relative to current injectable products include the elimination of pain and site reactions associated with weekly injections, elimination of weekly doctor visits or visits from the nurse, and elimination of interference/disruption of personal, family or professional activities associated with weekly visits.

Preterm Birth (PTB) is defined as delivery of less than 37 weeks of gestation. PTB occurs in ~12% of all US births. PTB remains the leading cause of perinatal mortality and morbidity, accounting for as many as 75% of perinatal deaths.

The expense associated with PTB involves not only the immediate cost of the preterm baby being treated in the hospital ICU setting, but includes the long term treatment costs for disabilities for the life of the child. Current total PTB related economic impact on the US health system far exceeds $26 billion, an estimated cost in 2006.

Behrman RE et al. in: Behrman RE, Butler AS, eds. Preterm Birth: Causes, Consequences, and Prevention. Washington, DC: The National Academies Press; 2006:329-354.

There is a significant unmet need for a ‘patient friendly’ product for the prevention of PTB. The only FDA approved product for the prevention of PTB must be given by an intra-muscular injection each week for a total of 18-22 injections.

 

LPCN 1107: A Novel Oral Alternative

LPCN 1107 Product Attributes:

  • Designed for oral administration twice daily of hydroxyprogesterone caproate (same active as in the only FDA approvd injectable product for the prevention of recurrent PTB).
  • Eliminates site reaction and pain at the site of injection
  • Eliminates regular doctor office visits or visits from the nurse (weekly visits for 16 – 20 weeks)
  • Significant absorption upon oral dosing of LPCN 1107 in healthy non-pregnant women
  • Good dose response demonstrated in healthy non-pregnant women
  • LPCN 1107 was well tolerated in single dose study
  • LPCN 1107 may be eligible for orphan drug designation

LPCN 1107, Lipocine’s oral hydroxyprogesterone caproate (HPC) product candidate has the potential to become the first oral HPC product for the prevention of preterm birth in women with a prior history of at least one preterm birth. Potential benefits of our oral product candidate relative to current once-a-week intramuscular (IM) injectable product include the elimination of pain and site reactions associated with weekly injections, elimination of weekly doctor visits or visits from the nurse, and elimination of interference/disruption of personal, family or professional activities associated with weekly visits. Lipocine has successfully completed a Phase 1 study under a US IND designed to determine the pharmacokinetics and bioavailability of LPCN 1107 relative to an IM HPC, as well as safety and tolerability, in healthy non-pregnant female volunteers.

17α-Hydroxyprogesterone caproate is a synthetic, steroidalprogestin that is similar to medroxyprogesterone acetate andmegestrol acetate. It is an ester derivative of 17α-hydroxyprogesterone formed from caproic acid (hexanoic acid).

17α-Hydroxyprogesterone caproate was previously marketed under the trade name Delalutin by Squibb, which was approved by the U.S. Food and Drug Administration (FDA) in 1956 and withdrawn from marketing in 1999.

The US FDA approved Makena from KV Pharmaceutical (previously named as Gestiva) on February 4, 2011 for prevention ofpreterm delivery in women with a history of preterm delivery, sparking a pricing controversy.

Synthesis

Hydroxyprogesterone caproate can be prepared by the following sequence:[13]

It is made from 16-dehydropregnenolone acetate (16-DPA),[14] product of the Marker degradation.

CUISINE OF TAMILNADU

Cuisine of Tamil Nadu

tour operators india
Like all other South Indian states, Tamil Nadu is also known for a wide variety of delicious food both for the vegetarians as well as the non-vegetarians. Grains, lentils, rice and vegetables are the main ingredients of the traditional foods of Tamil Nadu. Spices add flavor and give a distinctive taste to the Tamil cuisines. Some of the most common and popular dishes of the region are idly, dosai, vada, pongal and Uppuma. Coconut chutney and sambhar invariably form a part of most of the Tamil dishes.
The typical Tamil breakfast includes dosai, which is a pancake made from a batter of rice, idly (steamed rice cakes) and lentils (crisp fried on a pan), vada (deep fried doughnuts prepared from a batter of lentils), pongal (a mash of rice and lentils boiled together and seasoned with cashew nuts, ghee, pepper and cummin seed), uppuma (cooked semolina seasoned in oil with mustard, pepper, cummin seed and dry lentils). These are the main local dishes but there are several variations that are eaten with coconut chutney and mulaga podi.For lunch and the main course, the food consists of boiled rice, which is served with an assortment of vegetable dishes, sambar, chutneys, rasam (a hot broth prepared from tamarind juice and pepper) and curd. On the other hand, the non-vegetarian lunch and dinner include curries and dishes cooked with chicken, mutton or fish. Crispy Papad/Papar and appalam form an important part of a typical Tamil meal.Filter coffee is a famous and popular beverage of the people of Tamil Nadu in general and Chennai in particular. It is interesting to note that making of filter coffee is like a ritual as the coffee beans are first roasted and then powdered. After the grinding work is over, the powder is put into a filter set and then boiling water is added to prepare the decoction, which is allowed to set for about 15-18 minutes. The decoction is ready and can be added to milk with sugar according to taste. The coffee is poured from one container to another in quick succession so that the ideal frothy cup of filter coffee is ready.

Chettinad Cuisine

Chettinad cuisine is one of the spiciest and most aromatic in India. The name Chettinad cuisine comes from the place of its origin, Chettinad. Chettinad cuisine and delicacy is a specialty of Tamil Nadu and is a delight for non-vegetarian food lovers. The Chettinad cuisine consists of several variations of mutton, fish, and chicken items. The Chettinad Pepper Chicken is a specialty of all the non-vegetarian dishes. Dishes like biryani and paya are popular Tamil style of Mughali food. Paya is a type of spiced trotters broth and is usually eaten with either parathas or appam.
