Call for Proposals: Accelerating impact of long-acting technologies in low- and middle-income countries

The objective of this call for proposals is to speed the development of existing medicines, into long-acting products, for treatment and prevention of diseases including HIV and its coinfections/comorbidities, tuberculosis (TB) and malaria.


Safe and efficacious medicines are available for the prevention and treatment of major diseases, but their effectiveness can be compromised by poor treatment completion. Lack of adherence can worsen clinical outcomes, leading to increased mortality, persistent transmission and increased drug resistance in the case of antimicrobials and antivirals.  Analyses of treatment and prevention of HIV, malaria, and TB within public health programs show wide disparities in rates of completion, especially among specific populations and regions.[1],[2],[3],[4],[5]

Currently, most medicines in use require daily intake of oral tablets. Reasons for limited levels of adherence include: pill burden; duration of treatment (e.g., antiretrovirals (ART), maintenance phase for treatment of drug susceptible TB); stigma (e.g., treatment of TB, prophylaxis or treatment of HIV); discontinuation in access to health care for key populations (e.g. hepatitis C (HCV) treatment in people who inject drugs); and supply and programmatic issues. In addition, treatment interruptions are frequent in asymptomatic people (e.g., TB or malaria prophylaxis, HIV pre-exposure prophylaxis (PrEP) or ART).

Long-acting products have revolutionized other fields, such as schizophrenia and contraception, and could dramatically change the response to other major diseases affecting LMICs.

While not yet approved, long-acting products at various stages of development have been identified through wide-ranging consultations[6] and landscaping[7],[8],[9] that hold promise to dramatically transform the management of HIV and its co-infections/comorbidities, TB, or malaria, among other disease areas.

However, in the absence of intervention, an extensive time-lag for these new technologies to be available in LMICs can be expected. Therefore, Unitaid aims to support interventions that can accelerate development of game-changing long-acting solutions for global health impact.

Call scope

Under this call, Unitaid is soliciting proposals to support development of long-acting products of medicines to treat and/or prevent diseases affecting LMICs, notably HIV, HIV coinfections/comorbidities, TB, and malaria, with broader consideration for management of antimicrobial resistance (AMR). Proposals should include the following elements:

  • repurposing critical standard-of-care medicines into long-acting products, examples of such products may include injectables, implants, oral dosing technologies, or other; 


  • enabling sound commercialization to facilitate subsequent uptake and scale in LMICs for resulting products. Considerations include: capacity for adequate and quality-assured production; regulatory strategy for LMICs; licensure and pricing strategies that can facilitate introduction and broad access in LMICs.

Proposals submitted should clearly demonstrate the fit with the objectives set out above, the expected impact and value for money, as well as, the complementarity to similar projects in this area. 

Applicants are encouraged to consider products that can be introduced in the market within three to five years (i.e. products that could be eligible for purchase by major funders and countries as relevant and supply capacity created to address demand sufficiently by the end of this timeframe).

Topics which are out of scope for this Call include: a) proposals seeking the development of long-acting products including new chemical entities (NCEs), or new indications for approved drugs, that require full clinical development prior to submission to regulatory approval; b) proposals aiming to implement and/or deliver products at scale.

Proposals that include more than one product, leveraging investments across product-categories, and collaborative partnerships including industry are welcomed. Proposed project governance should consider the integration of a scientific advisory board.

Process for proposal submission

Note:  If selected, applicants should plan to be available for a face-to-face kick-off meeting with Unitaid, in Geneva, between 22-31 July (exact date tbc). In addition, successful applicants should plan to have sufficient human resource capacity available to advance a first draft of the project plan by early September.

Unitaid works through market-based interventions to achieve global market and public health impact. Proposals should clearly demonstrate the use of innovative and sustainable approaches to address key public health problems.

Applicants should be clear about the underlying assumptions made in their proposed approach, and should highlight any major risks or other factors that may affect the delivery of results. Finally, proposals are expected to outline a lean, concrete and clear pathway to results and impact.

The proposed implementing agency needs to demonstrate capacity/prior experience implementing projects of this nature, including capacity to address concerns of and seek input and buy-in from key civil society groups at all stages of the proposal.

All proposals received will be considered, but Unitaid reserves the right to not fund all the areas outlined in this call. Funding may be allocated to more than one successful proponent.
