Description

Reusable multi-dose, variable dose, single pen injector for type 2 diabetes and weight management
Field of the invention
The present invention relates to a liquid pharmaceutical compositions of Semaglutide delivered with a reusable pen injector device. In an embodiment, the pen injector device comprises one or more cartridges suitable for delivering multiple and different variable doses of Semaglutide for the treatment of type 2 diabetes and weight management. The present invention also relates to a novel liquid pharmaceutical compositions comprising Semaglutide in concentration of 3 mg/mL to 25 mg/mL and phenol at a concentration of 0.11% w/w to 0.5% w/w.
Background of the invention
Semaglutide is one of the useful drug for the treatment of type 2 diabetes and weight management. The drug is approved in an oral as well as injectable dosage form.
W02006097537 disclosed Semaglutide for the first time. The same document also disclosed certain injectable compositions of Semaglutide.
Semaglutide is a long-acting analogue of human glucagon like-1 peptide i.e. an Aib , Arg - GLP-l(7-37) analogue substituted on the s-amino group of the lysine residue in position 26 with an (S)-22,40-dicarboxy-10,19,24-trioxo-3,6,12,15-tetraoxa-9,18,23-triazatetracontan-l- oyl side chain. The side chain consists of two 8-amino-3, 6-dioxaoctanoic acid (ADO) spacers, one y-glutamic acid (Glu) spacer, and a fatty diacid (1, 18- octadecanedioic acid). Pharmaceutical dosage forms comprising Semaglutide are disclosed in WO 2006097537 and in WO 2019038412. There are two approved injectable brands of Semaglutide available, i.e. Ozempic® and Wegovy®.
Ozempic® is approved for treatment of diabetes and available in disposable pen injector and uses different device for different doses (Device 1: 0.25mg, 0.5mg; Device 2: Img; Device 3: 2mg). Ozempic® is available as a solution for subcutaneous injection wherein concentration of phenol is 5.5 mg/ml. Wegovy® is presented as a clear and colorless solution for subcutaneous injection in a 1 mL prefilled type I glass syringe (PFS) attached with stainless steel needle, rigid needle shield (type II/polyisoprcnc) and a rubber plunger (type Uchlorobutyl). The PFS is assembled into a single-use prefilled pen (PFP). Wegovy® is available with packs of 4 PFPs each: - 0.25 mg semaglutide in 0.5 mL (strength 0.25 mg); - 0.5 mg semaglutide in 0.5 mL (strength 0.5 mg); 1 mg semaglutide in 0.5 mL (strength 1 mg); - 1.7 mg semaglutide in 0.75 mL (strength 1.7 mg); - 2.4 mg Semaglutide in 0.75 mL (strength 2.4 mg).
One of the major drawback of the approved injectable (Wegovy®) Semaglutide formulations is that the injectable dosage form is available either in disposable single pen injectors or fixed dose, multiple dose injectors. So, a patient needs to use/buy disposable pen every week or need to buy different pen injector for different doses as per approved dosage regimen and for the entire time period of the therapy. The pen provided for injecting is a single use pen, and should be thrown out after each dose is administered. This not only increases the cost of therapy to the patient but also unnecessary waste is generated which has an impact on the environment also.
Further, as explained, in WO 2019038412, the Semaglutide liquid formulation is not stable when higher amount of phenol is used for formulating the higher dose of Semaglutide required for weight management therapy. Hence, the WO’412 document discloses formulations of Semaglutide with no or insignificant amounts of phenol. This typical formulation of Semaglutide probably necessitated the use of a single use pen for drug delivery.
Thus, it is required to research and develop a new formulation of Semaglutide that is more cost effective for patients, is stable enough to avoid use of single use pens for delivery, give better patient compliance and is environment friendly. Inventors of the present invention have surprisingly found that by optimizing the concentration of phenol in the formulation it is possible to formulate higher concentration of Semaglutide without impacting its stability. With such a stable formulation, it is possible to deliver multiple doses of Semaglutide using a multi-dose injector device containing a cartridge and the device can be reused by replacing with a new cartridge. Thus the current invention aims to provide a high concentration formulations of Semaglutide with optimized phenol concentration which is stable and which can be delivered by a multi dose reusable pen.
Summary of the invention
The present disclosure relates to a high concentration Semaglutide liquid composition delivered with a reusable pen injector device. In an embodiment, the pen injector device comprises one or more cartridges suitable for delivering multiple doses of Semaglutide. The present invention also relates to certain liquid pharmaceutical compositions comprising Semaglutide is in concentration of 3 mg/mL to 25 mg/mL and phenol is in a concentration of 0.11% w/w to 0.5% w/w.

One advantage of the pen injector is that it is provided with a mechanism that can reliably deliver a medicament with multiple dose via a single pen injector. Same device is able to deliver different doses for type 2 diabetes treatment as well as for weight management, in approved dosage form it can be delivered by different device.
Another advantage is that a pen injector is provided with a mechanism that will never deliver a volume of medicament larger than what the patient selected. Still another advantage is that a pen cap can be provided with a cartridge which may be changed and the pen injector can be reused for the drug delivery again and patient need not to buy new pen injector every time he wants a refill making the current invention cost effective also.

Table 5: Semaglutide composition in Multi-dose reusable pen injector as per present invention (Type 2 Diabetes)
Currently approved product is a multi-dose disposable pen injector but uses different device for different doses (Device 1: 0.25mg, 0.5mg; Device 2: Img; Device 3: 2mg)
Figure imgf000016_0001
The present invention thus relates to multi-dose reusable pen injector to deliver different doses from single device and suitable for the effective treatment of both, type 2 diabetes and for weight management therapy. Each device can deliver different doses as per the dosage regimens necessary for effective of type 2 diabetes therapy and weight management. From a single cartridge/device, it is possible to provide effective dosages from 0.25 mg dose of Semaglutide to 2.4 mg of Semaglutide through a single device to a patient. Thus, it is possible to provide multiple doses such as 0.25 mg/0.5 mg/1 mg/1.7 mg/2 mg /2.4 mg to a patient in need thereof. This will reduce significant cost to patient. The Pen device can also be reused multiple times with new cartridge to deliver required no of doses.
Advantage of the present invention over existing therapy are
• High concentration, stable formulations of Semaglutide.
• Multiple doses of variable different doses can be delivered from a single device.
• Device can be reused by replacing with a new cartridge.
• Cost effective option for patients.
• Better patient compliance though adherence to long term treatment. Following are non-limiting examples of high concentration, stable formulations of Semaglutide. It is illustrative and representing the preferred modes of carrying out the invention. The scope of invention is not limited to these specific embodiments only but should be read in conjunction with what is disclosed anywhere else in the specification together with those information and knowledge that are within the general understanding of a person skilled in the art.
